Frontend Engineer

Job Title: Frontend Engineer

Location: Redwood City, CA (Onsite)

Job Type: Full-Time

Who we are

We’re a stealth-mode startup made up of a close-knit team of seasoned engineers who thrive on tackling challenging problems and delivering high-impact solutions. Our culture is built on trust, autonomy, and the shared belief that the best solutions come from diverse perspectives and fearless experimentation. We value deep thinking, rapid iteration, and the courage to question everything.

Responsibilities

• Create, modify, and improve the front-end experience and long-term maintainability of product features and team tooling.
• Develop and ship large user-facing features and components that fit seamlessly into the overall product architecture, ensuring a cohesive and consistent customer experience.
• Design and implement production-quality web applications that are performant, secure, and accessibility compliant.
• Bridge the frontend to backend APIs and AI agents — connect frontend components to REST and event-driven APIs, AI agents, and data services built in Go, Python, or Java.
• Build and maintain reliable, type-safe contracts between the frontend and backend (REST, WebSockets, streaming responses).
• Collaborate on refactoring frontend code — improving naming, file structure, and component boundaries.
• Establish and maintain design token structure and Tailwind/shadcn theming conventions across the codebase.
• Partner with UX Design to set up and maintain Storybook as a living component library, documenting components as they're built.
• Resolve the root cause of complex frontend and UX issues, applying appropriate programming paradigms (object-oriented and/or functional) and front-end software design patterns.
• Write and maintain tests across the stack — unit, integration, and E2E — with particular care around API contracts and critical user flows.
• Contribute to CI/CD pipelines and ensure builds, tests, and deployments are reliable and fast.
• Help define what great looks like in an AI-native product — contributing to UX and engineering discussions, and building the interaction patterns that make streaming output, agent status, and AI-generated intelligence feel intuitive rather than opaque.
• Leverage AI-assisted development tools (Claude, Copilot, Cursor, etc.) as a natural part of your workflow to accelerate delivery and debugging.

 Core qualifications

• 3-5 years of experience building large-scale web applications with a focus on performance, security, and accessibility.
• Experience connecting frontends to APIs — auth, error states, loading patterns, streaming responses.
• Solid hands-on experience with React and TypeScript, including component architecture, hooks, and state management.
• Familiarity with one or more backend languages used in the stack (Go, Python) — enough to read, trace, and debug across the integration boundary.
• Comfortable writing tests across the stack using modern tooling (Vitest, Playwright, Testing Library, etc.), with particular familiarity with integration and E2E patterns.
• Startup-ready: comfortable with ambiguity, fast iteration, and building without a safety net.
• Collaborative by nature — thrives in cross-functional settings and is genuinely excited to learn new skills alongside teammates.

Preferred Qualifications

• Experience building interfaces or APIs for AI-native products — agents, streaming completions, tool-use UIs, or LLM orchestration layers.
• Experience building or contributing to a design system, including token management and component documentation.
• Strong understanding of responsive web design across devices and screen sizes.
• Working knowledge of accessibility standards (WCAG) and experience building and auditing for compliance.
• Experience working with data visualization libraries such as Recharts, Chart.js, Plotly, D3, etc.

Why Join Us:

• Shape the DNA of a product with massive market potential.
• Work alongside a small, elite team with deep domain expertise.
• Competitive equity, flexible work setup, and zero bureaucracy.
• Build something that matters—with speed, autonomy, and purpose.
