Job Description

About Flow

Flow Engineering is an AI-native requirements platform that makes complex engineering work clear, collaborative, and verifiable. We’re reimagining how complex hardware is built by pairing world-class engineers with AI agents to design, iterate, and ship faster than ever before.

About the role

Flow is hiring a staff frontend software engineer to own core user experiences in Flow and bring AI-powered workflows into a clean, intuitive UI. You will work closely with design, product, infra, and AI engineers to make complex systems engineering concepts feel simple and fast.

You will help define how “agentic systems engineers” and domain experts interact with Flow, from requirements views to reviews, simulations, and AI assistance.

What you’ll do

• Own major user-facing surfaces in Flow v3, including interactive requirements views, collaboration and review flows, and AI-assisted workflows.

• Implement high-quality, accessible UI using a modern frontend framework and component system.

• Integrate AI features into the product in ways that feel natural, interpretable, and helpful to engineers.

• Partner with design and product to iterate quickly on interaction patterns, prototypes, and new workflows.

• Help shape frontend architecture, design systems, and performance optimizations as the app and user base scale.

About you

• 8+ years of experience building rich, data-heavy web applications with a modern frontend framework.

• Strong experience with React (or similar) and TypeScript, including component design, state management, and testing.

• A product mindset: you think in terms of user journeys, edge cases, and clarity, not just individual screens.

• Comfortable collaborating closely with design and product, and giving and receiving feedback through iterations.

• Willingness to occasionally work across the stack (e.g., refining APIs, wiring up integrations) to ship features end-to-end.

Our stack (frontend-leaning)

• React and TypeScript as the primary frontend stack.

• Tailwind or a similar utility-first or component-driven styling approach.

• Integration with backend APIs and AI services built in TypeScript/Node.js.

How we work & values

• Speed over everything: ship Flow v3 in slices, not in one big bang.

• Own, downscope, ship, iterate: you’ll own features from idea to shipped UI.

• Maximum effort, maximum fun: high energy, high ownership, and a team you want to build with.

• Competitive salary and meaningful equity.

• Health, dental, and vision coverage.

• Flexible time off and support for learning, conferences, and great tools.
