You have 3+ years of backend experience in a language such as Golang, Rust or Python, excellent communication skills and familiarity with TDD, continuous delivery and agile methodologies. Using these skills, you’ll work closely with other engineers, product owners and key stakeholders to deliver secure, resilient and scalable solutions.

What You’ll Do

You'd be on a team with a well-defined goal. Your team-members are other engineers, and likely a few people from other functions like product management, data analysis, and design. You and your team decide what to do to achieve your goals.

As a Backend Software Engineer, you're expected to:

  1. Express requirements as code. Otherwise known as “good automated testing at all levels of the pyramid.” We like TDD a lot.

  4. Practice continuous integration and delivery.
  5. Work with databases and object storage.

  7. If you're on a team that operates a service: you'd also be expected to be on an on-call team, and your team is empowered to keep after-hours incidents below one per person per 3 months.
  8. Help grow your colleagues. Inspire, mentor and coach.
  9. Improve yourself. Raise your skill-levels and bring new approaches to your team.

Your success is measured by the pace and quality of the engineering solutions you deliver in your team. We define quality very broadly: it includes security, privacy, capacity, performance, reliability, cost-efficiency, etc.
