Job Description

Bellroy isn’t a software company that happens to make physical products. We’re a product company, and our software exists to give us a real competitive edge. That distinction matters. It means we care about quality and craft, not just delivery speed. We build systems that solve real-world problems for our customers, our team, and our operations, and we do it with care. We're extending the capabilities of our bespoke e-commerce platform, integrating with digital marketplaces around the world and supporting the release of exciting new carry goods. As we scale, we're looking for a developer who’s genuinely at home in functional programming – whether your background is in Haskell, Clojure, Elixir, F#, Scala, OCaml, Erlang, or similar – to help us build an elegant platform to support our growth. We care less about which functional language you’ve used, and more about whether you think in maps, folds and algebraic data types; about types and composition; about building systems that are correct, observable and evolve gracefully. While we love pure functional programming as much as the next lambda enthusiast, we're pragmatic enough to know that sometimes a clever hack beats a perfect abstraction. The key is knowing the difference.

Job Responsibility

  • Extending the capabilities of our bespoke e-commerce platform
  • Integrating with digital marketplaces around the world
  • Supporting the release of exciting new carry goods
  • Building an elegant platform to support our growth

Requirements

  • Have spent 2+ years writing production code in a functional language (for example Haskell, Clojure, Elixir, F#, Scala, OCaml, Erlang, or a strongly‑functional style in Rust, Kotlin or Swift)
  • Take pride in crafting code that's thoughtfully designed and built to last
  • Are more interested in mastering your craft than climbing the management ladder (though we're open to that changing as you grow with us)
  • Thrive in a cross-functional environment, collaborating with experts across product design, data science, logistics, and beyond
  • See your work as more than a paycheck - you're driven by the challenge of creating exceptional solutions
  • Have an insatiable curiosity for new ideas, whether they come from technical blogs or philosophy podcasts
  • Want to be part of a company that's using business as a force for good

Nice to have

  • Have tamed Nix and lived to tell the tale
  • Know your way around the AWS ecosystem
  • Can navigate Ruby on Rails codebases (we have a slowly shrinking, legacy Rails ecosystem that interfaces with our Haskell services)

What we offer

  • Learning budget
  • Culture of continuous learning through hack days, company-wide learning events, weekly Technology Team book clubs and mob programming sessions
  • Culture where intellectual honesty is expected
  • Autonomy built into workflow
  • Tools needed to turn great ideas into reality
  • Weekly “cooldown” days to improve skills, tooling and workflows
