Senior DevOps Engineer — Infrastructure Migration Project

We are looking for an experienced Senior DevOps Engineer to assess, plan, and execute the migration of our application infrastructure.

Our company develops and operates its own proprietary software platform, and the selected engineer will work closely with our internal development team.

The infrastructure consists of four isolated environments:

* Development
* Testing
* Staging
* Production

Each environment includes:

* Two frontend services
* One backend system consisting of more than 10 Docker containers
* PostgreSQL database
* Redis
* Potentially RabbitMQ
* Self-hosted Jenkins server and runners
* Private Docker Registry

The backend includes API services, data fetchers, Laravel Horizon workers, and queue-processing services.

The ideal candidate should have strong experience with Docker, Linux, CI/CD, Jenkins, PostgreSQL, Redis, RabbitMQ, networking, infrastructure security, backup and recovery, and production migrations with minimal downtime.

This is initially a project-based engagement focused on infrastructure migration. After the migration is completed, we may continue working with the engineer on a part-time basis for ongoing infrastructure support, maintenance, and optimization.

About SpeedSize

SpeedSize powers the next generation of video-led e-commerce. Our patented psychovisual AI and AI-first delivery remove a compromise the industry has lived with for 30 years, speed or quality, so brands can serve full-quality video and imagery at a fraction of the size and load. We work with premium enterprise brands and we're scaling fast.

The role

You'll own the GTM OS: the systems that power our entire go-to-market motion across sales, marketing, partnerships, and the handoffs into finance, operating as one cohesive system fed by clean, structured, real-time data.

You'll transform HubSpot into a ledger for the entire company, deploy a PRM, deploy Sybill, and prepare the OS for AI agents (e.g. Gemini Enterprise). You'll build the reporting the company's divisions run on day to day, and own the data quality that holds it all together.

What you'll own

• HubSpot as the company ledger. Architect and build the object and data model, lifecycle states, pipelines, properties, and workflows so HubSpot becomes the ledger the entire company runs on.
• Context graph (Sybill). Deploy and own the context graph. It auto-populates HubSpot with clean, structured data and gives the entire company a unified, data-driven, customer-centric brain to query.
• Partner system (PRM, e.g. Introw.io). Deploy and own the PRM: data model, deal registration, attribution, partner workflows, and payouts.
• Data architecture, quality, and automation. Own enrichment, routing, scoring, and attribution, and automate lead capture, handoffs, lifecycle, and renewals so teams move without manual setup.
• Integrations and MCP. Connect the stack through APIs and prepare it for MCP access so it's ready for AI agents (e.g. Gemini Enterprise).
• Reporting and forecasting. Build the pipeline, forecasting, and attribution reporting the company's divisions run on day to day, and the data-quality standards that keep it trustworthy.

Who you are

• A GTM systems builder. You build revenue systems that compound. You sit where marketing handoffs meet sales execution and post-sale expansion, and you turn business problems into scalable systems.
• Fluent in HubSpot and the wider GTM stack. You know HubSpot cold as the system of record, and you've worked across CRM, automation, and data tooling to make a stack operate as one.
• AI-native. You think AI-first, you're comfortable with the technology, and you can design a data structure and systems built for the agentic future.
• Outcome-driven. Beyond knowing workflows, you tie every build to the business outcome it drives and ruthlessly prioritize your work against them.
• An owner. You think in outcomes and handoffs, and you run a domain end to end.

Requirements

• Proven experience building and owning GTM systems across sales and marketing
• Deep, hands-on HubSpot expertise as the system of record
• Experience deploying and integrating a PRM and the wider GTM stack
• Workflow automation, data architecture, and data-quality governance (enrichment, routing, scoring, attribution)
• API integration work and data modeling
• Revenue forecasting and pipeline analytics
• Familiarity with Google Workspace and Slack
• Plus: experience with agentic AI, MCP, and context graphs (Sybill)

How we work

You'll work directly with the SVP of Sales & GTM and closely with our CEO and CTO. We move fast, build from first principles, and expect owners.

We operate in one of the most competitive and sophisticated categories on Amazon: Health & Wellness.

Our brands compete alongside industry leaders such as NOW, Pure Encapsulations, and Nature Made. We already have proven products, strong unit economics, and a solid operational foundation. 

To support this growth, we're looking for a highly organized and execution-focused Project Operations Manager who can bring structure, accountability, and operational excellence to our product and business operations.

About the Role

This is not a "track deadlines and send status updates" role.

We're a growing Amazon brand. We run like a tech team — ClickUp, sprints, Slack, clear ownership — but our product is e-commerce, not software. Right now we need someone to own the operational backbone of the company: build the processes, cut through the noise, and help us scale without losing speed or quality.

If you're the kind of person who walks into chaos and immediately starts thinking "here's how we fix this" — keep reading.

What You'll Own

• Manage our ClickUp and Slack workspace: tasks, sprints, priorities, accountability
• Translate leadership decisions into clear, actionable work for teams
• Keep projects moving — and remove whatever gets in the way
• Spot process bottlenecks and drive improvements before they become problems
• Keep distributed teams aligned across time zones and functions
• Track operational metrics: progress, velocity, KPIs
• Support leadership on strategic initiatives as the business scales

Must Have

• 2+ years in project management, operations, or a coordination-heavy role
• Hands-on experience with ClickUp, Jira, Asana, or similar tools
• Practical understanding of Agile / Kanban — not just theory
• Experience coordinating cross-functional teams
• Strong written and verbal English (B2+)
• Ability to manage multiple workstreams without losing focus

Nice to Have

• Background in e-commerce, Amazon, or consumer brands
• Experience in a startup or fast-scaling environment
• Work with distributed or remote teams
• Basic understanding of SDLC

Who You Are

• You don't wait for instructions — you create clarity yourself
• You think in systems and processes, not isolated tasks
• You own outcomes, not just activity
• You're comfortable with ambiguity and shifting priorities
• You don't need to be managed — you manage yourself

What Success Looks Like at 3–6 Months

• Teams have clear priorities and don't block each other
• Risks are visible before they become fires
• Leadership has a clean picture of what's happening across the business

• Processes are simpler, faster, and ready to scale

   

What We Offer

• Direct impact on company growth and operations
• Close collaboration with founders from day one
• High autonomy and real ownership
• Remote-first with flexibility and trust
• Competitive USD-based compensation
• Room to grow as the business grows

About the Role

We're a fast-growing HVAC company scaling from $1M to a $2M–$4M annual target. We're looking for an Executive Assistant / Chief of Staff — not a traditional VA — to become the owner's right hand and help build the company's operational backbone. This is a long-term, high-trust role with a clear path to Chief of Staff or Director of Operations.
 

What You'll Own

• Full inbox management: sorting, prioritizing, drafting responses, tracking follow-ups
• Calendar coordination: scheduling, reminders, meeting organization
• Task management: centralized tracking, weekly reporting, workflow organization
• Meeting support: attending, recording, documenting decisions and action items
• Daily/weekly reporting (revenue, open estimates, missed calls, reviews, KPIs)
• Client experience monitoring: reviews, reputation, communication quality
• Contractor coordination: SEO, marketing, suppliers, vendors
• Growth track: eventually training a future Office Manager, building SOPs, overseeing dispatch/CSR quality
   

Who We're Looking For

• Fluent Ukrainian or Russian + English (C1 or higher)
• Higher education degree (business, management, economics, finance, or engineering a plus)
• Prior experience as an EA, Operations Manager, Project Manager, or Chief of Staff preferred
• Strong, hands-on proficiency with AI tools (ChatGPT, Claude, Gemini, etc.)
• Excellent written communication and high organizational standards
• Proactive, systems-thinking mindset — able to solve problems independently and bring recommendations, not just questions
• Comfortable handling confidential information with discretion
• Genuinely seeking a long-term career within one company (this is not a short-term or part-time gig)
   

What Success Looks Like

• 6 months in: Independently running communications, tasks, reports, and meetings; freeing up 15–20+ hours/week of the owner's time
• 12 months in: A true right hand — participating in operational decisions, hiring, and building the company's management system

We're building a prediction-markets and order-book trading platform where prices move in real time and real money changes hands on every trade. We're looking for a Full-Stack Developer to own features end-to-end, from the trading and market UIs to the APIs and services that price, match, and settle those trades. The front end is React + TypeScript. The back end is Node.js + NestJS. If you like problems where latency, correctness, and money all matter at the same time, this is that kind of product.

Work is split roughly evenly between front-end and back-end, and you'll spend it near the interesting parts of the system: live market feeds, order handling, and the trading experience itself.

Technical Stack:
- Frontend: React (hooks, modern state management), TypeScript, HTML5, CSS3
- Backend: Node.js, NestJS, TypeScript
- Real-Time: WebSockets / SSE, live market and order-book feeds
- Database: PostgreSQL, Redis
- Messaging: Kafka, RabbitMQ, or Redis Streams
- Data viz: TradingView, D3.js, Recharts, or Chart.js
- Web3 (a plus, not a requirement): ethers.js / viem, EVM chains, wallet integrations
- Version Control: Git

What You'll Do:

- Own features end-to-end: product discussion, design, build, deploy, and keep them healthy in production.
- Build trading and market UIs: order entry, live quotes, price impact, positions, and settlement views.
- Build the NestJS services behind them: market data, order handling, settlement, and the APIs that feed the UI.
- Work with real-time data: WebSocket fan-out, reconnect / resume, and keeping the UI in sync with a fast-moving backend.

What We're Looking For:

- 2+ years of full-stack experience shipping production features.
- Strong React and TypeScript (hooks, state management, performance).
- Solid Node.js and NestJS (REST APIs, services, background jobs).
- Comfortable with SQL (PostgreSQL) and Redis.
- Real-time experience with WebSockets / SSE, and a feel for what breaks at scale.
- Product sense: you can take a rough requirement and ship a usable feature from it.

- Proficient with AI-assisted development: you work fluently with agentic coding tools (Claude Code, Cursor, and similar), drive real multi-step work through them, review and correct what they produce, and know where they fall short.
- Clean Git habits and production deployment experience.

Nice to Have:

- Trading, fintech, iGaming, or other real-money / real-time systems.
- Order-book and matching concepts: limit / market orders, price-time priority, partial fills, maker / taker.
- Data-heavy or charting UIs (TradingView, D3.js, Recharts, Chart.js).
- Web3 / DeFi: ethers.js / viem, wallets (MetaMask, WalletConnect), on-chain data and indexing. We may add an on-chain surface later, so this is a real plus.

How We Work:

- Small, flat team with a short path from idea to production, and no bureaucracy.
- You own your slice and have a genuine say in how it's built.
- Open feedback, shared code.

What We Offer:

- Fully remote work (Europe / Ukraine time zone).
- Competitive salary.
- Flat company structure: no bureaucracy.
- Opportunities for professional growth.
- Work-life balance with flexible working hours.
- Access to various learning resources and development programs.
- 20 days of vacation time.
- 5 illness days.

At Promova, we're reimagining language education to help today's minds unlock their full potential — building learning that's calm, personal, and genuinely useful for people around the world. Our 150+ teammates share one mission: connect people, bridge cultures, and support lifelong learners everywhere — in every country except aggressor states (yes, even Antarctica).

We pair AI with human creativity so people can speak with confidence and feel at home in a new language. If you like solving real engineering problems, building systems that hold up under load, and shaping the platform learners rely on every day — you'll fit in here.
 

We're looking for a DevOps Engineer to join our Core Infrastructure team.

Our infrastructure team is the backbone for Promova and several internal products. We build reliable, cost-aware infrastructure that lets engineering teams ship without fighting their tooling. From AI features and Kubernetes clusters to developer tooling and multi-cloud setup, you'll help shape the foundation the rest of the company builds on.
 

Why This Role

Own the platform. You'll have end-to-end ownership of core infrastructure across AWS, Hetzner, Cloudflare, Kubernetes, and modern platform tooling.

Work on problems that matter. You'll design infrastructure that scales, improve reliability, automate the manual parts, and build the foundation for the AI features learners use every day. We'll be honest: some of this is greenfield, some is untangling what already exists — both are on the table.

Shape where the platform goes. There's real room to standardize infrastructure across products, bring in automation, make developer experience better, and influence architecture decisions across the company.

Build in an AI-first team. AI is part of how we build products and how we work day to day. You'll help our infrastructure support AI workloads — and use AI in your own engineering workflow.
 

What You'll Work On

• Own and evolve Promova's core infrastructure across AWS, Hetzner, and Cloudflare.
• Design, build, and maintain Infrastructure as Code with Terraform.
• Build and improve CI/CD pipelines with GitHub Actions, Argo CD and self-hosted runners.
• Manage and optimize Kubernetes (K3s) and AWS ECS environments.
• Improve reliability, observability, and incident response with Grafana, Prometheus, Loki, and related tooling.
• Support the infrastructure behind our AI features and internal platforms.
• Improve cloud cost visibility and bring spend down where it makes sense.
• Build provisioning and onboarding automation that makes developers' lives easier.
• Strengthen platform security through secrets management, access control, and solid infrastructure practices.
• Collaborate with fellow infrastructure engineers and help shape engineering standards across teams.
   

What We're Looking For

• 4+ years as a DevOps, Platform, Infrastructure, or Site Reliability Engineer.
• Strong hands-on experience with AWS and modern cloud infrastructure.
• Solid Infrastructure as Code experience, ideally Terraform, Ansible.
• Experience running Kubernetes in production.
• Good understanding of CI/CD pipelines, GitHub Actions and Argo CD.
• Comfortable with Docker and Linux administration.
• Experience with observability tooling such as Grafana, Prometheus, and Loki.
• Experience with secrets management such as Vault or AWS Secrets Manager.
• Strong scripting skills (Bash and/or Python).
• An ownership mindset, good judgment, and clear communication.
• Experience mentoring teammates or leading infrastructure work is a plus.
   

Interview Process

• Intro call with the Recruiter
• Technical Interview
• Bar Raising Interview
• Offer

Sounds like you? Apply — and help build the platform behind how people learn languages.

About the role

No legacy, no bureaucracy, — just you and a small but incredibly strong engineering team making the right technical decisions together. A chance to go deep into fintech (card payments, compliance, settlement) and actually shape the product architecture.
 

Finance focus. This role is for our Finance direction: settlements, reconciliation, bank integrations, and integration with the core banking system. You'll go deep into the money flow — how funds move, settle, and reconcile across gateway, processor, schemes, and banks.
 

Fintech experience is essential. We need someone who already knows payments and fintech — this isn't a domain to pick up on the side. We expect proactivity and a readiness to take on and own the domain expertise: be the person the team relies on for settlement and reconciliation logic.
 

Important: we need a strong engineer with deep technical background. The engineering team is top-tier, and the bar is high. We're not looking for average — we're looking for people who can make decisions independently and own the outcome.
 

What you'll do:
 

Backend (Kotlin)

• Financial Core: double-entry ledger (immutable), settlement engine (MDR calculation, netting, payouts), pricing engine (IC++/blended), rolling reserve management
• Integrations: REST API integrations with payment gateway, card processor, KYC/KYB, SEPA/SWIFT payouts
• Webhook processing: ingestion and processing of vendor webhooks
• BPMN workflows: Camunda 8 — service tasks, user tasks, DMN decision tables for business processes (merchant onboarding, AML investigation, dispute management, settlement)
• Compliance: transaction monitoring rules, sanctions screening integration, SAR workflow
• API: REST API for merchant portal and ops panel
   

Frontend (Next.js)

• Merchant Portal: dashboard (transactions, volumes, conversion), settlement history, payouts, chargebacks, API keys, webhook settings, onboarding wizard
• Ops Panel: case management (AML, disputes), treasury dashboard, compliance dashboard, underwriting, merchant management
• Developer Portal: API documentation (OpenAPI), integration guides, sandbox
   

General

• Reconciliation: multi-layer reconciliation engine (gateway ↔ processor ↔ scheme ↔ bank ↔ safeguarding)
• Reporting: regulatory reporting, scheme reporting (Visa/MC), financial (P&L)
• Testing: we're AI-first when it comes to testing — fully automated coverage at every level: unit, integration, E2E. No manual QA — you write code, you write tests. E2E tests for the full payment flow (auth → capture → settlement → payout), integration tests with vendors, BPMN process tests via Camunda API

Requirements:
 

Must have

• 6+ years of Kotlin or Java (Spring Boot) — REST APIs, JPA/Hibernate, transaction management
• 3+ years of Next.js / React — SSR, TypeScript, state management
• PostgreSQL — queries, migrations, indexes, JSONB
• REST API design — versioning, error handling, idempotency
• Git, CI/CD
• Webhook processing, event-driven architecture
• Okta / OAuth2 / OpenID Connect

Fintech / payments experience — a must, not a nice-to-have: settlements, reconciliation, bank integrations, integration with a core banking system

AI-fluency — active integration of AI tools (Cursor, Claude Code, Codex) into daily engineering work. Not just "aware of AI" — uses it to multiply productivity, with a critical eye for generated output

Proactivity — identifies problems before they surface, proposes solutions, drives them to done. Doesn't wait to be told what to do

English: confident reading and listening is a must. Good spoken English is a strong plus
 

Nice to have:

• Understanding of double-entry accounting
• Camunda / BPMN experience
• Tailwind CSS, shadcn/ui
