Job Description

ABOUT THE ROLE

We are building a new product at the intersection of agentic AI and hard backend engineering. The work runs deep: distributed systems, demanding data problems, and AI engineering that takes large language models beyond demos, into systems you can trust.

As a Senior Frontend Developer you will own the client side of it: a React application where rendering quality, performance, and developer experience all matter. You will set the standard for how our interfaces look, feel, and hold up — and AI is part of the daily craft here too.

WHAT YOU’LL DO

• Design and deliver major frontend features end to end: component architecture, implementation, tests, and production rollout.
• Own the hardest problems in our client: state management at scale, rendering performance, and a component system that stays coherent as it grows.
• Shape the UX: turn loosely specified product ideas into intuitive, polished, visually consistent interfaces.
• Lead delivery with junior developers: break features into tasks, review their code, and raise the bar.
• Build the interfaces our AI agents are experienced through — and use AI tooling deliberately in your own workflow.
• Document the designs and decisions that keep the codebase evolvable.

WHAT WE EXPECT FROM YOU

• Own outcomes: when you take a feature, it ships — designed well, tested, and supported in production.
• Drive technical excellence: set, refine, and enforce the standards the rest of the team builds on.
• Sweat the pixels: hold the bar for interfaces that are intuitive, fast, and beautiful.
• Multiply the team: mentor junior developers and give feedback that makes people better, not just code.
• Think in abstractions: our codebase is built on a few deep concepts — you extend them without breaking them.
• Make AI a multiplier: use agents and AI tooling deliberately, and help define how the whole team uses them.

WHAT YOU BRING

• Deep modern React: hooks, state management (Redux or similar), performance profiling, and component API design.
• Strong TypeScript and JavaScript fundamentals: the language, the event loop, the browser.
• Solid Java (or another strong object-oriented language) — the best frontend work here spans both sides of the wire.
• Real experience shipping complex single-page applications: routing, forms, async data flows, error handling.
• Production discipline: thorough testing (unit and end-to-end), CI, accessibility, and an instinct for performance.
• A track record of mentoring developers and leading feature delivery.

BONUS POINTS

• A design system at customization depth (e.g. MUI): theming, design tokens, dark mode.
• End-to-end tooling: Playwright or Cypress.
• Server-driven UI or component-registry architectures.
• Hands-on LLM / agentic AI experience: prompting, tool calling, or agent frameworks.
• Python.

QUALIFICATIONS

• Bachelor degree in Computer Science or Computer Engineering.
• Other degrees considered with a proven track record in software development.
