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.

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.
