Apply now and help build reliable, scalable, and innovative embedded solutions used by customers worldwide.

Company overview:
 

Graphio auto-discovers processes, reveals best case scenarios, and keeps every AI agent and human on it - all with metadata only.
 

No workflow changes. Fast rollout in less than 2 days.

We’ve built and scaled before: the team behind Graphio.ai previously built upSWOT, a B2B platform adopted by hundreds of financial institutions, which was later acquired by Uptiq.  We’re applying those lessons in execution, delivery, and scale to Graphio.ai.

Supported by senior leaders from Experian, Mastercard, Lattice, BambooHR, Altrata, SAP, JackHenry, FIS, Pfizer, Workday, Customertimes, and more (graphio.ai/investors).

Position Overview:

We are looking for a Strong Middle Product Designer to work under Product Owner supervision, and design the product experience that turns complex workflow intelligence into clear, trustworthy actions for busy operators.
 

Graphio.ai reconstructs cross-team workflows from API-enabled metadata, automatically generates an ideal workflow (golden path), detects deviations that signal broken handoffs, and delivers weekly/monthly reporting to a single accountable owner. Your job is to make this feel obvious: what the system found, why it matters, what to do next, and how to tune it - all without overwhelming the user.
 

This is a B2B SaaS product used by senior operators. The bar for clarity, speed, and confidence is set high.

Key Responsibilities:

• Own end-to-end product design from UX research and user testing to final UI, including dev-ready handoff.
• Make complex output understandable and trustworthy: decision support, and “what changed / what to do now” flows that drive action.
• Partner closely with the Product Manager, Machine Learning and AI specialists, and Software Engineers to turn model outputs into user-ready experiences and to iterate quickly.
• Maintain a scalable design system (components, variables) to keep the product consistent and fast to build.
• Lead user research in a pragmatic way: interviews, usability tests, and lightweight validation with operators to uncover confusion, friction, and adoption blockers.
• Design onboarding and first-time experience flows that support fast rollout and short time-to-value, without workflow changes.
• Use product data and qualitative feedback to identify drop-offs, iterate on UX, and improve engagement with reports and alerts.
• Raise the overall quality bar: establish design principles for clarity, actionability, and trust in AI-driven insights.

Preferred Qualifications:

• 4+ years of product design experience, ideally in B2B SaaS, analytics, workflow tools, or data-heavy products.
• Strong portfolio showing end-to-end thinking: problem framing, exploration, trade-offs, and shipped outcomes.
• Experience designing for complex data, decision-support, or “insights-to-action” products (not just dashboards).
• Strong systems thinking: ability to turn complex datasets into clear information architecture and interactions.
• Strong decision making capabilities and self-sufficiency.
• Proficiency in Figma.
• Comfort collaborating closely with engineers and iterating quickly in a startup environment.
• Understanding of accessibility, usability best practices, and how to design for busy operators.
• Nice to have: familiarity with front-end constraints (HTML/CSS/JS), design for enterprise settings, and experience with AI-assisted product experiences.

What we offer:

• Ownership of core product surfaces where customers experience the value of Graphio.ai (ideal workflow review/editing, deviations, reporting).
• Tight collaboration with Product, Machine Learning, and Engineering with fast iteration cycles and clear feedback loops.
• A chance to design for clarity in a complex domain where good UX directly drives business outcomes.
• Growth into design leadership: as the company scales, you will have the opportunity to help hire, mentor, and lead a growing team of product designers, shaping our design culture, standards, and system.
• Remote-friendly team with low overhead and high trust.
• Competitive compensation and room to grow as the product and team scale.

Company Operating Requirements:

At Graphio.ai we run a high-ownership, mission-driven team with clear operating rules. Please read these carefully before applying:

• LinkedIn profile is required (company policy). Employees are required to keep a current LinkedIn profile that shows their Graphio.ai position and is linked to the official Graphio.ai company page (company logo visible on the profile). Profile standards are provided during onboarding.
• Synchronized team vacations. The team takes coordinated time off four times per year to keep planning aligned and reduce context switching. Dates are announced in advance.
• Startup constraints. Vacation timing may be restricted during critical company periods. We plan time off as a team and communicate constraints early.
• Relocation readiness. Team members may reside in Ukraine, but must be prepared to relocate with their families to Europe or the United States if the company requests it and it becomes legally possible. Any relocation would be discussed in advance.
• Non-standard schedule. The role requires flexibility to collaborate across time zones. This may occasionally include early/late meetings depending on customer and team needs.
• US Eastern Time (ET) collaboration. This role requires regular overlap with US East Coast (ET) working hours.
• Zero slow offboarding. We run lean and fast. When the fit isn’t there, we act quickly: employment may be ended within a day and access is removed immediately.

Application requirement: short intro video:

Please include a short self-introduction video (2–3 minutes). You can add the link directly to your resume or submit it through the hiring platform in any available way (YouTube, Loom, Google Drive, or similar).

• No need for a polished production, a simple smartphone recording is perfectly fine.
• This does not replace live conversations, it only helps us speed up the first screening and understand your communication style and motivation.
• In the video, please cover:
  • Who you are and 2–3 measurable outcomes you delivered in recent roles
  • Why you are applying for this role at Graphio.ai
  • Why you are leaving or have left your previous role
  • Your view on how a high-ownership startup team should operate (pace, ownership, communication, and work-life balance expectations)
• Applications without the video may not be reviewed.

Final note:

Graphio.ai is not a 9-to-5 corporate environment. We move fast, operate with high ownership, and expect proactive execution without micromanagement. Graphio.ai is a strong fit for people who actively seek challenges for personal growth - especially those who want to build their own company one day and see this as a place to learn how high-performing startups execute.

ABOUT PROJECT

We are a leading technology company that uses real-world data in real-time to optimize campaign performance and revolutionize health decision-making. Leveraging proprietary datasets and methodology, we target healthcare professionals and patients with an unprecedented level of accuracy—delivering unparalleled results to the clients we serve.

Company overview:
 

Graphio.ai stops revenue loss before it happens by detecting broken handoffs between teams.
 

We analyze API-enabled metadata from your existing systems to automatically identify when Sales, Customer Success, Legal, Finance, Product, and Operations are misaligned - before deals stall, renewals fail, or contracts slip.
 

No workflow changes. Fast rollout in less than 2 days.

AI learns what successful execution looks like in your company and alerts you to dangerous deviations in real time.

We’ve built and scaled before: the team behind Graphio.ai previously built upSWOT, a B2B platform adopted by hundreds of financial institutions, which was later acquired by Uptiq.  We’re applying those lessons in execution, delivery, and scale to Graphio.ai.

Supported by senior leaders from Experian, Mastercard, Lattice, BambooHR, Altrata, SAP, JackHenry, FIS, Pfizer, Workday, Customertimes, and more (graphio.ai/investors).

Position Overview:

We are looking for a Junior/Middle Backend Developer to help build and maintain the backend services that power Graphio.ai’s workflow intelligence product.

In this role, you will work on C# / .NET–based APIs and backend services that support customer onboarding (workspace setup and invites), system integrations, metadata ingestion and processing, and generation of user-facing outputs such as weekly/monthly reports and alerts.

You will join a small team where shipping, reliability, and clean engineering practices matter. This is a role for someone who wants to grow fast by working on real production systems, with support from senior engineers and clear technical direction.

Key Responsibilities:

• Build and maintain backend services and REST APIs using C# / .NET (ASP.NET Core) that powers core Graphio.ai flows: workspace setup, user access, system integrations, metadata ingestion, reporting, and alert delivery.
• Write clean, maintainable code and follow team standards; contribute to refactoring and long-term code health when needed.
• Work on ingestion and processing of metadata (events, entities, timestamps, identifiers) used for workflow intelligence and reporting.
• Design and implement asynchronous and event-driven processes using RabbitMQ (queues, background jobs, retries, idempotency).
• Improve API reliability and performance: clear contracts, consistent error handling, pagination, and rate limiting.
• Work with databases:
  • MongoDB for operational and metadata storage,
  • ClickHouse for analytics, aggregations, and reporting workloads.
• Write and optimize queries, design schemas and indexes, participate in migrations, and help ensure data integrity and consistency.
• Implement authentication, authorization, and secure-by-default practices (permissions, tenant boundaries, safe handling of sensitive data).
• Write unit and integration tests; participate in code reviews and apply feedback quickly.
• Monitor and troubleshoot services in production: use logs, metrics, and tracing; contribute to root-cause fixes.
• Document backend services and APIs: how they work, how to run locally, and how to debug common issues.
• Contribute to engineering workflows: Git-based collaboration, containerized development (Docker), and CI/CD practices.
• Collaborate with Product, Frontend, and Engineering peers to deliver features in small, shippable increments in a remote environment.

Required Qualifications:

• 1–2 years of backend development experience (or equivalent production experience through projects).
• Strong knowledge of C# and .NET (ASP.NET Core, Web API).
• Experience building REST APIs, including authentication, authorization, error handling, pagination, and versioning.
• Hands-on experience with MongoDB: schema design, indexes, aggregations, and query optimization.
• Understanding of analytical databases; experience with or willingness to learn ClickHouse (aggregations, partitioning, performance tuning).
• Experience with message queues and background processing; RabbitMQ is a strong plus.
• Understanding of asynchronous processing, eventual consistency, and retry mechanisms.
• Knowledge of secure engineering basics (auth, permissions, data protection).
• Comfortable working in a remote team: clear written communication, ownership of tasks, and predictable delivery.

Nice to Have:

• Experience building event-driven architectures and data pipelines.
• Experience working with large datasets and performance optimization.
• Familiarity with observability tools (logging, metrics, tracing).
• Startup experience or proven ability to move fast without heavy process.
• Experience with Kubernetes or cloud platforms (AWS, GCP, Azure).

What we offer:

• A practical growth role on real backend services used by customers, with clear feedback and mentorship from senior engineers.
• Work on meaningful product flows: metadata processing, workflow intelligence outputs, and reporting/alerts.
• A startup environment with low bureaucracy and fast iteration - you ship, learn, and improve quickly.
• Remote-friendly team with a simple setup and high trust.
• Competitive compensation (based on level) and growth opportunities as the team scales.

Company Operating Requirements:

At Graphio.ai we run a high-ownership, mission-driven team with clear operating rules. Please read these carefully before applying:

• LinkedIn profile is required (company policy). Employees are required to keep a current LinkedIn profile that shows their Graphio.ai position and is linked to the official Graphio.ai company page (company logo visible on the profile). Profile standards are provided during onboarding.
• Synchronized team vacations. The team takes coordinated time off four times per year to keep planning aligned and reduce context switching. Dates are announced in advance.
• Startup constraints. Vacation timing may be restricted during critical company periods. We plan time off as a team and communicate constraints early.
• Relocation readiness. Team members may reside in Ukraine, but must be prepared to relocate with their families to Europe or the United States if the company requests it and it becomes legally possible. Any relocation would be discussed in advance.
• Non-standard schedule. The role requires flexibility to collaborate across time zones. This may occasionally include early/late meetings depending on customer and team needs.
• Zero slow offboarding. We run lean and fast. When the fit isn’t there, we act quickly: employment may be ended within a day and access is removed immediately.

Application requirement: short intro video (required):

Please include a short self-introduction video (2–5 minutes). You can add the link directly to your resume or submit it through the hiring platform in any available way (YouTube, Loom, Google Drive, or similar).

• No need for a polished production, a simple smartphone recording is perfectly fine.
• This does not replace live conversations, it only helps us speed up the first screening and understand your communication style and motivation.
• In the video, please cover:
  • Who you are and 2–3 measurable outcomes you delivered in recent roles
  • Why you are applying for this role at Graphio.ai
  • Why you are leaving or have left your previous role
  • Your view on how a high-ownership startup team should operate (pace, ownership, communication, and work-life balance expectations)
• Applications without the video may not be reviewed.

Final note:

Graphio.ai is not a 9-to-5 corporate environment. We move fast, operate with high ownership, and expect proactive execution without micromanagement. Graphio.ai is a strong fit for people who actively seek challenges for personal growth - especially those who want to build their own company one day and see this as a place to learn how high-performing startups execute.

Are you detail-obsessed, analytical, and ready to learn how e-commerce actually works at scale?

Argo Brands is a US-based consumer goods company with four active brands — including top-selling Amazon products with 50,000+ reviews. We sell across Amazon, TikTok Shop, Shopify, Walmart, Target, Kohl's, and Snappy. We're growing fast and need a sharp, reliable person to support our marketplace operations team.

This is an entry-level role. We're not looking for someone who already knows everything — we're looking for someone who is organized, analytical, persistent, and genuinely excited to learn how marketplace operations work from the inside. We'll invest in training you. In return, we need someone who takes ownership, catches mistakes before they become problems, and doesn't need to be chased.

What You'll Do

• Support day-to-day operations across four retail marketplaces: Walmart, Target, Kohl's, and Snappy
• Create and optimize product listings — titles, descriptions, bullet points, keywords, images
• Build and maintain spreadsheets, trackers, reports, and dashboards
• Monitor advertising performance and key business metrics across platforms
• Track P&L, profitability, and operational KPIs
• Automate repetitive tasks using AI tools and help improve team workflows
• Analyze data and flag opportunities or issues to the team
• Prepare reports, summaries, and presentations for management
  
  Who We're Looking For
• We're open to two profiles:
• Students or career-starters with no direct experience — if this is you, what matters most is strong English (written and spoken), an analytical mindset, high attention to detail, and the ability to stay focused and accurate on repetitive tasks for extended periods. If you're the type who notices errors others miss and takes pride in clean, structured work — we want to hear from you.
• Candidates with 1+ year of experience on Amazon, Walmart, or any other marketplace — your hands-on knowledge of listing management, advertising metrics, or operational workflows is a strong advantage.
  
  You're the Right Person If
• You take ownership and drive tasks to completion without needing constant check-ins
• You notice inconsistencies, errors, and missing information before they become problems
• You organize information clearly and naturally create repeatable processes
• You're proactive — you identify opportunities for improvement and suggest solutions
• You're a fast learner who adapts quickly to new tools, platforms, and workflows
• You actively use or are genuinely curious about AI tools to improve productivity
• You're comfortable working with data, metrics, and performance analysis
• You perform well in a fast-paced environment where priorities shift
• You can stay focused and accurate on repetitive, detail-oriented tasks over time
  
  Hard Skills (Required or Learnable)
• Strong Excel or Google Sheets skills — or a clear ability and willingness to develop them
• English proficiency — written and spoken (this is a must, as all work is in English)
• Basic understanding of e-commerce or marketplace logic (Amazon, Walmart, or similar) is a plus, not a requirement
• Familiarity with AI tools (ChatGPT, Claude etc.) is a strong plus
  
  What We Offer
• Full training and mentorship — we'll teach you how marketplace operations work at a real scale
• Remote work
• A front-row seat to how a multi-brand US e-commerce company operates across major retail platforms
• Real responsibilities from day one — this is not a "shadow someone" internship
• Clear growth path as you develop expertise
• A fast-moving, international team that values ownership and initiative

We are looking for a Senior Full-Stack Developer (AI-Native) to join the project full-time. This person will own the full stack — backend, frontend, and AI/agent layer — with no splitting between projects. They need to be a thinking partner, not an executor — someone the client's technical leadership wants to work with directly.

Your responsibilities will include:

• Own the full stack end-to-end — backend, frontend, and AI/agent layer — architecture decisions, performance work, integration, testing — without hand-holding.
• Work directly with the client's technical leadership as a thinking partner.
• Build and maintain LLM-powered agent systems with observability, evaluation, and structured tracing.
• Cover backend, frontend, and infrastructure independently — no "that's not my area."
• Use AI-assisted development (Claude Code or equivalent) fluently and extensively as a primary tool.

What we expect from you:

Core stack — Backend:

• Python — FastAPI, SQLAlchemy, Alembic.
• PostgreSQL + PostGIS — spatial data modelling, multi-tenant isolation at the database, session, and repository layers.
• Redis — async task queues.
• Unit & integration tests — Pytest.

Core stack — Frontend:

• React + TypeScript — strict typing; comfortable with generics, discriminated unions, and type inference.
• Next.js — App Router, Server Components, server-side data fetching, middleware, Server Actions.
• Zustand — store design, selectors, SSR hydration concerns.
• Unit & integration tests + E2E — Vitest, Cypress or equivalent.

AI / Agent Layer:

• LLM-powered agents — SSE, tool-use patterns, prompt engineering.
• Observability & evaluation — structured tracing of agent runs and tool calls, usage tracking, analytics.

Infrastructure:

• AWS — ECS, S3, containerized deploys.
• Terraform — infrastructure as code.
• CI/CD — GitHub Actions.

Engineering Practices:

• Static typing — Pyright as CI gate; type hints on every signature, no escape hatches.
• Multi-tenancy — tenant isolation at the database, session, and repository layers.
• Git discipline — conventional commits, granular atomic history, clean PRs.

Tooling — AI-assisted development (Claude Code):

AI is a primary, everyday tool on this project, not an occasional helper. We expect a candidate who has moved well beyond ad-hoc prompting and treats their AI setup as part of their engineering craft.

• AI-native development — non-negotiable. Daily, extensive, fluent use of Claude Code (or equivalent) for reading, writing, refactoring, debugging, and navigating a large codebase. Working without AI in the loop is not how this team operates.
• Plain prompting is not enough. "Ask ChatGPT a question and paste the answer" is the baseline we expect candidates to be past. We're looking for someone who engineers their AI workflow: rich structured context, project conventions and reference examples fed to the model, clear scoping, iteration, and rigorous review of generated output.
• Skills, Hooks, Subagents— must understand, must be able to build, and already uses in real work. The candidate should be able to clearly explain what each is, and — critically — has already created and uses them day-to-day, not just heard of them:
  • Skills — reusable, on-demand instruction/knowledge packages that extend the agent's competence for a given task type (e.g. scaffold a module, generate a PR, run a review) and encode the team's conventions.
  • Hooks — deterministic, automated triggers on lifecycle events (pre-commit, before/after edit, on stop, etc.) executed by the harness itself — e.g. auto-running lint/typecheck/tests on changed files, or guarding protected areas.
  • Subagents — delegating multi-step or parallel work (large refactors, audits, codebase research) to scoped agents, with verification of their output.
• MCP awareness — understands the Model Context Protocol and how to connect AI to real context and tools (codebase, Git, issue tracker, browser, observability) rather than working blind. Hands-on MCP usage is a strong plus.
• Structured change management — artifact-driven workflow from exploration through implementation to verification.
• Critical, not credulous — reviews everything the model produces, never commits code they don't understand, knows where AI accelerates the work (boilerplate, tests, scaffolding, exploration) and where it does not (complex domain/architecture logic). AI is a force multiplier for their own thinking, never a copy-paste crutch.

Soft skills / Mindset:

• Initiative — proactively asks questions, proposes solutions, flags issues without being asked.
• Software Engineering Mindset — understands fundamentals, not just framework recipes; can reason about problems from first principles.
• Comfortable with the unknown — says "I don't know, let me find out," explores and digs in.
• Thinks aloud — communicates where they are, what they're considering, what they're unsure about.
• Fast — moves quickly without sacrificing quality; comfortable with startup pace and shifting priorities.
• Collaborative but opinionated — contributes ideas, challenges assumptions respectfully.
• English — B2+ — daily verbal and written communication with the client and their team; working proficiency minimum.

What We Offer:

• Work at a Top-employer company (according to DOU 2025).
• A strong culture built on empathy, trust, openness, and real care for employees.
• Competitive compensation with regular reviews.
• Paid vacation and sick leave.
• Medical insurance.
• Personal learning budget and access to top HR tools, platforms, and practices.
• Team events and regular team-building activities.
• Flexible hybrid work model with an office in central Kyiv.
