Who we're looking for

We are looking for a hands-on, growth-oriented Senior Backend Engineer to strengthen our Technical (Foundation) Cluster - the team that builds, transforms and maintains the core services, shared libraries, and internal platforms that keep every product clusters (teams) moving fast and safely.

You will work side-by-side with other senior engineers, EMs, and tech-PMs to design robust architectures, evolve our infrastructure, and make sure engineering fundamentals stay rock-solid as we scale.

Our stack
  • Backend: Ruby on Rails 7+, PostgreSQL
  • Infrastructure: Docker, Kubernetes, AWS
  • CI/CD & VCS: Jenkins, GitLab, Bitbucket
Why you’ll like it here
  • Impact at scale: your work reshapes the engineering landscape for dozens of squads and millions of users.
  • Strong engineering culture: autonomy, psychological safety, and a bias for action.
  • Growth path: mentorship from Staff and Principal Engineers who’ll support your own move toward Staff level.
  • Modern tooling & cloud-native mindset: Kubernetes, IaC, and continuous delivery are the norm, not the exception.
  • People-centric benefits: flexible hours, remote-first processes, and a learning budget you control.

Ready to build the foundations that everyone else stands on?

Apply now and let’s architect the future together.
