  • • Create clear, modern, well-tested code.
  • • Collaborate across teams in a product-driven environment.
  • • Conduct code reviews and continuously look at ways of improving our ways of working.

  • • An interview with the Hiring Manager.
  • • Challenge Stage - Contextualised to the role.
  • • A final, values-alignment interview.
  • • WHAT'S THE CULTURE LIKE AT PRIMER?
  • • We're building a culture where people can do their best work and be proud of the impact they have. You'll be working with people who are mission-driven, smart, and reflective, and who are genuinely invested in building exceptional products and delivering success for our merchants.
  • • We work remotely, and have done since day one. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships through great remote working practices and thoughtfully designed face-to-face time, including workations, our annual company retreat, and access to co-working spaces across most major cities.
  • • The work is challenging. Scaleups are a challenge, and building category-defining products is a challenge. But there's a meaningful difference between a challenge and a struggle. At Primer, the right challenge comes with the right support: strong onboarding, a collaborative environment, and a team that is genuinely invested in your success. It's never something you face alone.
