Software Engineer- London

Flow is massively accelerating the development of next-generation hardware systems. We’re on a mission to reinvent the way humanity develops its most important machines.

We’re backed by Sequoia Capital with angel investors including Patrick & John Collison (Stripe), David Helgason (Unity) and Kyle Parrish (Figma).

Flow is the default requirements tool for complex systems engineering used by next gen space, defense, automotive and robotics companies. When humanity returns to the Moon, builds fusion power, or lands the first interplanetary colony - Flow will have played a vital role.

You’ll help build features that tackle some of the world’s toughest hardware engineering problems - and depending on your experience, you’ll take on increasing ownership and leadership responsibilities as we scale.

• Own understanding problems: work with customers, customer success and sales to clearly define customer problems.

• Own designing solutions: contribute to solution design by identifying simpler, better solutions.

• Build MVPs & iterate quickly: build features, gather feedback and iteratively improve features that solve our customer problems.

• Fix customer issues: jump on calls with users to troubleshoot and deploy feature improvements within hours.

If you’re more experienced (4+ years):

• Lead from the front: hire, mentor and manage best-in-class talent.

• Develop deep expertise and ownership in an area that drives Flow forward: such as, distributed systems, product design or performance.

• Builder at heart: You have 2+ years of experience as a software engineer (we’ll level appropriately based on experience).

• Problem solver: A track record of sucessfully solving real human problems.

• High Agency: driven to solve the most important problems even if no one has told you to

• Iterative Development: experience in shipping MVP solutions, gathering feedback and improving solutions to solve user pain faster.

• Strong technical skills: adept at JavaScript and React, including performance implications in browsers.

• Strong communicator: clear, concise and direct.

• Backend: Golang

• Frontend: TypeScript / React / Next.js

• Infrastructure: Terraform, AWS

• Containerization: Docker

• Database: PostgreSQL

• APIs: GraphQL (Hasura, Apollo)

We’re hiring across multiple levels.

• If you’re earlier in your career, you’ll build and ship core features with guidance.

• If you’re more experienced, you’ll take ownership of entire product areas, lead by example, and help shape the future of Flow’s engineering culture.

1. Speed over everything. If you go over a pothole at 20 mph, you really feel it. If you go over at 200 mph, you barely feel it. Everything we do, we need to do with urgency. This is our superpower and why we win. This is a discipline that requires effort and focus every day.

2. Own, Downscope, ship, iterate: We work in small, fast cycles. Our philosophy is to downscope and ship. The goal is to get a v1 out today and learn from seeing it used. We work with users not at them. Execution is the sole currency by which our customers value us. This does not always mean success at the first iteration, but we must be fully committed to delivering.

3. Fundamentals done well: Most success comes from mastering the basics. The trade off is always scope, never quality. This is why we prioritize simplicity. Doing so requires extreme clarity of thought: a talent for cutting to the essence of a problem, communicating it well and then solving it.

4. Disagree and Commit: To move fast, we have to decide fast. That means debating ideas hard, then committing fully once a decision is made.

5. Enjoy the climb: Climbing Everest is hard. The air thins, your body falters, and you pass those who didn’t make it. But we’re here to keep climbing. This is the work that will define us. Enjoy the climb. The view at the top only means something if you loved the journey getting there.
