Software Development Engineer - Frontend Infrastructure

You’ll own the core web stack at Sana - from our TypeScript/React frontend to the Node services, tooling, and monorepo infrastructure that power it. This is a role for engineers who love unblocking others: you’ll design and maintain the build systems, frameworks, and developer workflows that let teams ship fast, safely, and with confidence. You’ll work on everything from core web architecture and performance to CI, testing, and local development, ensuring our web platform is modern, secure, and a joy to build on., Own and evolve Sana’s TypeScript/React/Node foundations, including frameworks, services, and conventions * Maintain and improve our monorepo tooling: build tools, dependency management, scripts, and shared services * Design and refine local development, testing, and build workflows so they’re fast, reliable, and easy to use * Optimize web performance, reliability, and security across our frontend and Node services * Shape and implement our testing strategy (unit, integration, end-to-end, visual) and related tooling * Maintain and improve CI/CD pipelines, including caching, checks, and deployment workflows * Define and champion best practices for web development, debugging, and observability across teams * Collaborate closely with product engineers to identify friction points and remove them through better tooling and architecture, With Flex Work, we’re combining the best of both worlds: in-person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you’ll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote “home office” roles also have the opportunity to come together in our offices for important moments that matter.
