Role Description 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. What you’ll do - 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. Qualifications - 7+ years of professional experience in frontend software development. - Experience working on frontend infrastructure, platform, or developer experience teams. - Deep expertise in TypeScript and React. - Strong opinions on developer experience, loosely held. - Eye for design and attention to detail. - You treat other engineering teams as customers. - Comfort operating across the stack when needed. Requirements - 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). - 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. Benefits - Competitive Salary: The salary range for this position is $170,000 - $225,000 + equity. - Comprehensive Benefits: Health, dental, and vision insurance. - Remote friendly with WeWork access. - Unlimited PTO, shared downtime during the federal holiday calendar, and company-wide off time at the end of each year. - 401(k) match. - Lifestyle & wellbeing stipends. - Salary top-up during military reserve duty. - Fully paid parental leave. - Child and pet care reimbursement during travel.
