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.

What you’ll do

• Own key services and shared components in the cluster: design, develop, and operate them in production.

• Shape architecture together with other senior engineers: break monoliths into well-bounded modules, improve scalability and performance, and keep technical debt under control.

• Raise the bar on code quality and reliability through thoughtful design reviews and well-reasoned refactoring.

• Drive foundational improvements (observability, CI/CD, testing frameworks, security hardening) that make every team faster.

• Collaborate closely with PdM, Staff Engineers and CTO to translate business vision into required technical foundation and realistic milestones.

• Share knowledge: mentor mid-level developers, document best practices, and present learnings at internal tech talks.

• Contribute to hiring and onboarding by taking part in interviews and helping newcomers land smoothly.

Our stack

• Backend: Ruby on Rails 7+, PostgreSQL

• Infrastructure: Docker, Kubernetes, AWS

• CI/CD & VCS: Jenkins, GitLab, Bitbucket

About you

• 5–8 years of professional backend development experience.

• Deep appreciation of how rock-solid foundations accelerate every product team - and the drive to deliver them.

• Proven track record of designing and shipping production systems that serve thousands of users.

• Solid understanding of distributed system fundamentals: data modelling, caching, queues, monitoring, and failure scenarios.

• Comfortable owning features end-to-end — from RFC to production roll-out and post-mortem.

• Clear communicator who can explain trade-offs, listen to feedback, and build consensus.

• Passion for clean, readable code and a pragmatic approach to technical excellence

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.
