Software Engineer, React Focus

Job Description
You'll set technical direction for a TypeScript frontend platform serving a large data-intensive engineering program. This is a hands-on role: you'll write code, own architecture, and raise the ceiling for a team of ~6 engineers. Expect to work directly with backend, product, and end users.

What you'll do

• Co-own architecture for a React/TypeScript/Next.js application backed by gRPC/protobuf services
• Drive design of data-access layers (BFF/API boundaries, caching, pagination, streaming) where payload size and memory pressure are real constraints
• Set and enforce standards across a Turborepo monorepo: shared packages, versioning, build/CI performance, dependency hygiene
• Lead technical design reviews; write the design docs and white papers that anchor them
• Diagnose hard problems: memory exhaustion, render performance, pipeline issues
• Mentor engineers across levels and enable the team to work faster
• Work directly with customers and stakeholders to shape requirements, then decompose them into scoped, estimable work

Required Education, Experience, & Skills

• 6+ years building production software; 4+ in TypeScript/JavaScript and Node
• Deep React experience, including performance profiling and state/data-fetching architecture at scale
• Demonstrated ownership of system-level design decisions and their consequences
• Strong written communication: design docs, technical proposals
• Track record of mentoring and elevating other engineers
• Comfort operating with ambiguity and defining the problem
• Ability to obtain and maintain a DoD Secret clearance (U.S. citizen)

Preferred Education, Experience, & Skills

• gRPC / protobuf, especially large-payload or streaming scenarios
• Turborepo, Nx, or comparable monorepo tooling
• API design (REST, gRPC, BFF patterns) and versioning strategy
• Agentic / LLM-assisted development workflows and tooling
• Playwright or comparable E2E frameworks; test strategy across the pyramid
• CI/CD pipeline design and build optimization
• Data visualization at scale (AG Charts, D3, or similar)
• Storybook and component library ownership
• Wireframing and UX collaboration; comfort sketching a flow before building it
• Defense, aerospace, or other regulated-environment experience
