We're building an AI copilot for web testing automation. It enables manual and automation QA engineers to turn their manual testing flows into production-ready automated E2E testing scripts, saving hours of manual work and coding. We are a small team with zero bureaucracy, focusing on real users. We optimize for shipping value - not hype.
About the role:
You'll own the entire frontend and product UX, meaning you decide how the product looks, feels, and works. You'll design flows, build the UI, maintain the architecture, and set the quality bar for anything that touches the interface. Backend and AI are covered by a strong team of engineers.
Your focus in the first three months:
- Refactor backend-frontend communication and state management. The current architecture was vibecoded – you'll make it ready for feature scaling.
- Establish a clean design system from existing components.
- Ship token-by-token LLM response streaming to improve perceived performance.
- Design user onboarding from scratch.
- Build a user-friendly error system with clear resolution paths.
Why you should join us:
- Real ownership. You're not implementing someone else's Figma file. You decide how the product looks and feels.
- A small team that ships fast and skips bureaucracy. We benefit from direct feedback from users and quick iteration cycles.
- The backing of JetBrains. We are financially secure, with no reliance on external VC funding.
Who we're looking for:
A design/frontend engineer who can take a vague problem and turn it into a clear, usable, production-ready feature.
What matters most:
- Design-first thinking and UX intelligence over pixel perfection. You care more about whether something makes sense than whether it looks “pretty”.
- Strong product intuition. You notice UX friction, small paper cuts, and architectural smells – and feel responsible for fixing them.
- Prototype-and-ship mentality. You explore options quickly, consider alternatives, choose a direction, and move on.
Required experience:
Tech stack: React, TypeScript (web or desktop applications)
- Strong working knowledge of React and frontend architecture – enough to keep the codebase clean while actively using AI coding tools.
- Experience designing and implementing frontend systems end to end, not just isolated components.
- A portfolio or examples showing full ownership: projects where you designed and built the frontend yourself.
- At least one full year of experience in a startup or fast-moving team.
- Active experience with AI coding tools (Cursor, Claude Code, etc.) with a clear understanding of when they help – and when they hurt.
Nice to have:
We’d be especially excited if you have experience with any of the following (side projects count):
- Product design or product management.
- Electron or desktop app development.
- E2E testing – you’ve written tests yourself or worked closely with test automation.
- Early-stage or 0-to-1 projects where UX quality was critical.
- AI-powered products or LLM-based features.
