[Hiring] Senior Frontend Engineer @Re:Build Manufacturing

Role Description

If you've 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. We're 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.

What You'll Do

• 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
  • Version-controlled project plans
• Building interfaces for AI agent interactions including:
  • Streaming chat
  • Proactive coordination alerts
  • 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

Qualifications

• 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

Requirements

• 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

Benefits

• Full health/dental/vision
