Front End Developer Designer Jobs in Austin, TX (NOW HIRING)

• Design, build, and maintain core user-facing features in Circuit's web application.

• Translate product requirements and design direction into polished, responsive, and accessible UI.

• Contribute to frontend architecture, patterns, and technical decisions in collaboration with engineering peers.

• Leverage agentic tools (Claude Code, Cursor) throughout the development cycle - scoping, implementation, testing, and bug triage - and help improve the team's shared agent tooling and context.

• Own features end-to-end, from implementation through testing, QA, and production release.

• Write and maintain unit, integration, and end-to-end tests to ensure long-term reliability.

• Instrument, monitor, and debug production frontend issues using observability tooling (Datadog RUM, tracing, structured logging), and use real-user data to drive performance improvements.

• Participate actively in technical discussions, design reviews, and planning sessions.

• Provide thoughtful code reviews and mentorship to support team-wide quality and growth.

• Collaborate closely with Product and Design to clarify requirements, surface tradeoffs, and improve UX.

• Identify and drive incremental improvements to performance, accessibility, developer experience, and frontend tooling.

• Manage individual priorities and deadlines while maintaining a high standard of execution.

• 7+ years of professional frontend or full-stack engineering experience building and shipping production web applications.

• Proven experience operating as a staff or principal-level individual contributor within a collaborative engineering team.

• Experience collaborating closely with Product and Design partners to iterate on UX and balance technical and product tradeoffs.

• Track record building AI-powered product surfaces: chat interfaces, streaming responses, optimistic/incremental rendering, and designing UX around non-deterministic outputs.

• Demonstrated ability to take loosely defined product requirements and turn them into high-quality, production-ready solutions.

• A track record of improving code quality, developer experience, or frontend practices through example and influence rather than authority.

• Comfort operating in ambiguous, fast-moving environments and managing individual priorities without heavy process or oversight.

• Fluent with agentic coding tools (Claude Code, Cursor, or similar) - comfortable delegating implementation to agents, reviewing and validating AI-generated code, and knowing when not to.

• Experience working with performance, reliability, and maintainability concerns in large or evolving frontend codebases.

• Advanced proficiency in TypeScript, React, HTML, and CSS, with a track record of building complex, user-facing features.

• Strong proficiency with CSS Modules and component-scoped styling approaches.

• Experience with modern state management patterns using React Query for server state and Zustand for client state.

• Experience building and maintaining shared component libraries with Storybook, visual regression testing (Chromatic), and accessibility tooling.

• Strong experience designing and implementing responsive, accessible interfaces that follow modern UX and accessibility standards.

• Experience with monorepo tooling and workflows (Turborepo, Nx, or similar) and managing dependencies across multiple frontend packages.

• Hands-on experience writing and maintaining unit, integration, and end-to-end tests (e.g., Playwright, Vitest, React Testing Library).

• Experience building and consuming RESTful APIs, with understanding of API design best practices and error handling patterns.

• Hands-on experience with CI/CD pipelines, GitHub Actions, and deployment automation. Experience with Docker, infrastructure tooling, and DevOps practices is highly valued.

• Familiarity with modern development workflows and tooling, including Git, Linux-based environments, and containers.

• Comfortable working across the full stack when needed - familiarity with backend concepts, databases, and API development is a plus.

• Working knowledge of Go and experience with Go, Docker, Kubernetes, and cloud platforms (AWS, GCP, Azure) is a plus.

• Familiar with integrating authentication/identity providers.

• Skilled at building the scaffolding that makes agents effective: authoring CLAUDE.md/context files, custom slash commands and skills, MCP integrations, or running agents on remote/headless dev environments.

• Awareness of emerging standards like A2UI, AG-UI, MCP Apps and similar.

If you've built in this space, we'd love to hear about it. Relevant experience might include:

• Building performant, interactive data visualizations with libraries such as D3.js, Recharts, Nivo, or similar

• Working with WebGL, Three.js, Babylon.js, or other 3D rendering tools in a browser context

• Designing navigation patterns and interaction models for complex visual environments (e.g., graph traversal, spatial zoom/pan, scene hierarchy)

• Thinking about rendering performance at scale - large datasets, real-time updates, level-of-detail strategies

• Background in game development or interactive simulation - the mental models transfer well

• Strong problem-solving abilities and comfort operating in ambiguity.

• Excellent communication skills, with the ability to explain technical concepts to non-technical stakeholders.

• Highly collaborative across Product, Design and Engineering.

• High ownership mentality with a bias toward action and results.

• Adaptable, curious, and energized by the pace of an early-stage startup.

• Low-ego collaborator who values feedback, iteration, and shared success.
