  • Integrating with digital marketplaces around the world
  • Supporting the release of exciting new carry goods
  • Building an elegant platform to support our growth
  • Building features that not only work today but evolve gracefully tomorrow

Requirements

  • Have spent 2+ years wielding Haskell or another functional programming language
  • Take pride in crafting code that's thoughtfully designed and built to last
  • 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
  • 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

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
  • Autonomy built into workflow
