🚀 About Flow

Flow is massively accelerating the development of next-generation hardware systems. We're the core collaboration layer for complex, regulated engineering—used by the most important space, defense, automotive, and robotics companies of our era.

Backed by Tier-1 VC for our Series A. Angel investors include Patrick + John Collison (Stripe), David Helgason (Founder, Unity), and Kyle Parrish (VP Sales, Figma).

Flow is already the de facto reference for agile systems engineering in hard tech. When humanity returns to the Moon or builds fusion power on Earth—Flow will have played a small but vital role.

👷‍♂️ What You’ll Do

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.

• Build and ship features that accelerate solutions to urgent global challenges.

• Take ideas from customer calls to production within hours.

• Contribute to brainstorms by identifying simpler, better solutions.

• Write clear, readable, and maintainable code.

• Jump on calls with users to troubleshoot and support your own features.

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

• Own product ideation and delivery for a team of talented engineers.

• Lead from the front — especially on the unglamorous stuff — and set an excellent example for others.

• Hire, mentor, and nurture best-in-class talent.

• Develop deep expertise in an area that drives Flow forward — whether that’s taste, distributed systems, product, or browser performance.

❤️ About You

• Passionate about solving real human problems.

• You love the feeling of getting things done.

  • “Perfect is the enemy of good.”

• You’re not afraid to form strong opinions —

  • And even less afraid to change them with new evidence.

• Excited to explore new challenges, even outside traditional “technical” domains.

• Comfortable with compromise if it means solving user pain faster.

• Always striving to understand the bigger picture (“Why”).

  • And you speak up when you don’t — others may be wondering too.

• A strong communicator: clear, concise, and courteous.

• You have a strong understanding of JavaScript and React, including performance implications in browsers.

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

🖥️ Our Tech Stack

• Backend: Golang

• Frontend: TypeScript / React / Next.js

• Infrastructure: Terraform, AWS

• Containerization: Docker

• Database: PostgreSQL

✨ Leveling

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.
