About the role

  • As one of the first 15 employees, you’ll get to work directly with the founders and Heron's senior team, working both on new initiatives & making sure our products solve problems for existing customers.

  • We promote an outcome-focused, low-bureaucracy, engineering-first work environment with an emphasis on delivering customer impact at high velocity.

What we're looking for

We are not looking for specific frameworks, skillsets, and experiences. We value above all else folks who want to make real customer impact by building great software.

For example:

  • You thrive at solving tough problems
    • You enjoy breaking down challenging problems into simple & well-designed solutions
    • You are fact-driven and want to measure the real impact of your work
  • You enjoy building products and making real-world impact
    • You take responsibility over end-to-end deployment of what you build
    • You like shipping code frequently, iteratively, and collaboratively
    • You value MVPs and customer impact over perfectly engineered systems
    • You care about scalable infrastructure & process. Even better if you are the one to help improve / implement the system! e.g., DDD
    • You choose the best framework / technology for the task, even if you might have favourites. We work primarily in Python / Flask / FastAPI on the backend, Terraform / GCP for infra, and React / Javascript / Typescript / Vercel on the frontend, but are always experimenting with what framework enables the greatest performance and delivers the most value
  • You like to work in an fast-paced, high-growth, team-based environment
    • You are entrepreneurial. This means having a growth mindset, finding problems without being told about them, thinking independently about issues and clearly advocating your position, and taking full ownership of your work, even if things go wrong
    • You are a team player. You value diversity & inclusion in the workplace, are a helpful teammate, and understand best practices for building products as part of a team e.g., code review / version control


  • Thursday company lunches (always vegan-friendly!)
  • Nest pension (UK) // 401k plans (US)
  • Free psychotherapy sessions via Spill
  • Flexible work from home policy
  • Remote December: we go remote for 6 weeks in Dec/Jan to facilitate long home visits or other extensive yearly travel
  • Private health insurance through Vitality (UK)/Cigna (US)
  • Cycle to Work Scheme
