Senior Frontend Engineer

AtRe:Build our mission is to ensure the next generation of important products are made at scale in America. We are laying the foundation for a better future for our customers employees and communities by revitalizing Americas manufacturing base and creating meaningful jobs across the country including in historically deindustrialized regions.

We operate an advanced end-to-end manufacturing platform that partners with industrial companies and innovators to take products from first concept to full-scale production in critical verticals including aerospace and defense electrification medical energy and environment and robotics and automation.

The way we operate is as important as the work we do. Its guided by TheRe:BuildWay 16 principles that shape how we collaborate with each other partner with our customers and vendors and contribute to the communities where we operate.(link toThe Re:Build Way principles)

If youve worked alongside hardware teams you know the damage that results from a missed change request or critical context that was never relayed to the right person. Reflow exists to close that gap. Were building the first AI-powered platform purpose-built for hardware product development one that listens across the tools teams already use maintains a structured picture of every program and proactively coordinates across disciplines when things inevitably change.

This is a ground-floor opportunity for a hands-on frontend engineer to shape the user experience of a high-potential product with the support of a parent company leading innovation in engineering and manufacturing.

Were seeking a frontend engineer who cares deeply about building interfaces that are fast intuitive and delightful. The ideal candidate has shipped production React applications and has strong opinions on component architecture and design systems. You should already be using AI coding tools like Cursor Copilot or Claude to accelerate your work with excitement about building the product that finally replaces the spreadsheets and status meetings that hardware teams have been stuck with for decades.

This senior engineer will work alongside our engineering team and head of product to build the interfaces through which users manage structured engineering artifacts (requirements project plans dependencies) interact with ambient AI agents and get real-time visibility into project health across disciplines. The role is hands-on - you will be coding daily while contributing to frontend architecture decisions and helping grow the design system as we scale.

Your day-to-day responsibilities will include:

• Building production-grade React applications with TypeScript
• Developing and maintaining a shared component library
• Building rich interfaces for structured engineering data: requirements with traceability phase/gate tracking dependency graphs task boards with discipline tags and version-controlled project plans
• Building interfaces for AI agent interactions including streaming chat proactive coordination alerts and AI-generated status summaries and deliverables (proposals SOWs reports)
• Implementing portfolio-level dashboards for engineering leaders and executives showing cross-project cost schedule and risk
• Writing well-tested code with unit and end-to-end tests
• Collaborating with backend engineers on API integration and client SDK usage
• Contributing to frontend architecture decisions code reviews and engineering best practices

• 5 years building production web applications with 3 years focused on React
• Demonstrated proficiency using AI coding tools (Cursor Copilot Claude etc.) to accelerate development
• Expert-level expertise with React TypeScript and modern JavaScript
• Strong experience with component-driven development design systems and tools like Storybook
• Proficiency with CSS frameworks (Tailwind CSS preferred) and responsive design
• Experience with modern build tools (Vite esbuild or similar)
• Understanding of API integration patterns (REST OpenAPI generated clients)
• Ability to balance rapid iteration with maintainable well-tested code

• Have worked in early-stage 0 to 1 startup environments
• Familiarity with hardware development engineering workflows or project management processes
• Experience building UIs for AI/LLM-powered features (streaming responses chat interfaces structured AI output)
• Familiarity with headless component libraries (Base UI Radix Headless UI)
• Background in data visualization or dashboard-heavy applications
• Understanding of authentication/authorization patterns (OIDC JWT)
• Experience with end-to-end testing frameworks (Playwright Cypress)
• Background in B2B SaaS platforms project management tools or technical collaboration products
