Senior Frontend Engineer

### Who you are
- 7+ years of professional experience in frontend software development
- Experience working on frontend infrastructure, platform, or developer experience teams. You've built shared libraries, design systems, component frameworks, or internal tooling that other engineers depend on
- Deep expertise in TypeScript and React. You've thought seriously about component API design, render performance, state management boundaries, and how to ship library code that other teams consume without friction
- Strong opinions on developer experience, loosely held. You care about making other engineers productive and can balance long-term platform health with near-term team needs
- Eye for design and attention to detail. You hold UI to a high visual and interaction quality bar
- You treat other engineering teams as customers. You also care about the end users downstream (the operators using what gets built on top of your platform)
- Comfort operating across the stack when needed. You don't stop at the frontend boundary if the right solution involves a backend change
- Experience with module federation, micro-frontend architectures, or scaling frontend monorepos
- Familiarity with Node.js, Postgres, and OpenFGA
- Familiarity with web application security (authentication, authorization, XSS prevention) and experience applying it across full stack applications
- Experience building or contributing to design systems at scale
- Active Security clearance (or ability to obtain one) and willingness to travel onsite at least quarterly to perform user research and help debug issues

### What the job involves
- Vannevar's Frontend Platform team builds and maintains the frontend foundation that the entire Vannevar platform runs on. We turn cross-product needs into stable, well-documented platform capabilities so product teams can ship fast, stay consistent, and focus on mission problems
- We're looking for a senior frontend engineer to join this small, high-leverage team. You'll work on shared libraries, developer tooling, and the application shell (the code that every Vannevar product depends on)
- You'll also build user-facing platform features that directly impact how operators and analysts experience the product
- Own and evolve core frontend libraries and the application platform that Vannevar's products are built on
- Design and implement shared infrastructure: routing, authentication, error handling, UI components, and cross-app patterns
- Improve developer experience: faster local dev, better build pipelines, and clearer documentation
- Partner with product teams to understand their needs and turn recurring patterns into reusable platform capabilities
- Mentor and guide engineers across the organization on frontend architecture and best practices
