Frontend Developer (React, TypeScript)

At JetBrains, code is our passion. Ever since we started, back in 2000, we have strived to make the strongest, most effective developer tools on earth. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create. We're currently building No Pressure, an AI-powered simulator for role-playing and debugging difficult conversations (such as feedback, conflict, negotiation, and others). It is a human-centered, UX-first AI product – a web application with interactive conversational AI that helps people learn through virtual meetings with AI characters. We’ve completed an MVP, secured the budget for its further development, and are now moving into the pilot phase with our first customers. It’s a bold, design-led, user-first product, and we’re looking for people who are excited to build something truly new, meaningful, and well-crafted from the ground up.

About the role:

You’ll be a hands-on frontend developer building and scaling a UX-first AI product from MVP to pilot and beyond. You’ll own the frontend of the product, implementing complex, user-facing features – from learning flows and AI-driven interactions to admin dashboards, analytics, and billing – working closely with design and product teams to deliver fast, clean, and production-ready experiences. This role is senior in scope. We’re looking for a frontend engineer who is comfortable owning large parts of the product, making architectural decisions, and shaping how the frontend evolves as the product scales. You’re expected to proactively suggest solutions and improvements, while also respecting and accurately implementing product and design decisions.

In this role, you will:

• Own the frontend of product features, including learning paths, recommendations, the AI coach, and real conversation debugger.
• Build and support frontend experiences for AI/agent-driven workflows and interactive conversational interfaces.
• Build and maintain admin interfaces, including dashboards, analytics views, reporting, and configuration panels.
• Implement the UI for core product functionality, including billing, roles and permissions, and usage tracking.
• Turn prototypes into scalable, maintainable architecture.
• Develop the frontend codebase, shaping its architecture, and making technical decisions to ensure scalability and maintainability as the product grows.

Requirements

Must have:

• 3+ years of professional frontend web development experience.
• Strong experience with React and TypeScript.
• The proven ability to build responsive, interactive UIs (forms, dashboards, and modals).
• Experience prototyping quickly and iterating into production-quality code.
• The ability to write clean, readable, and maintainable code.
• Good design sensibilities and attention to UI/UX details.
• Experience working closely with Figma and design prototypes.
• A solid understanding of client-server architecture and REST APIs.
• A bachelor’s or master’s degree in computer science, engineering, IT, mathematics, or a related field.

Nice to have:

• Experience with real-time communication (WebRTC, LiveKit, or similar).
• Experience integrating AI/LLM-based features into frontend applications.
• Experience building SaaS products.
• Familiarity with frontend-adjacent infrastructure and tooling (e.g. Docker, CI/CD pipelines, error monitoring tools, basic deployment, or environment setup).
• Experience with design systems or reusable component libraries (Figma + scalable UI).
• Familiarity with product analytics and usage tracking.

Qualities and experience

Must have:

• A strong sense of ownership and responsibility.
• A focus on real product impact, not just implementation.
• The ability to balance initiative and autonomy with strong respect for design intent and product direction.
• Experience making frontend architecture or technical decisions within an existing product.
• Experience working cross-functionally with designers, PMs, or stakeholders.
• Clear evidence of skill growth, role progression, or increasing scope over time.

Nice to have:

• Experience in early-stage startups or 0→1 products.
• Comfort working in fast-moving, ambiguous environments.
• Experience owning features or product areas end to end.
• Mentorship or knowledge-sharing experience.
• The ability to learn new tools and frameworks or switch tech stacks confidently.
• Experience working directly with end users.
• Openness, empathy, kindness, and strong communication skills.
