Staff Ruby Engineer

We are looking for an experienced and strategic-thinking Staff Backend Engineer to join our R&D team (250+ people: developers, QA engineers, designers, technical support engineers, DevOps engineers, and product managers).

This is a key technical leadership role — Staff Engineer in our company is not just an expert developer, but a person who takes responsibility for the technical success of their cluster (a group of 2–4 cross-functional micro-teams working on related functionality).

We expect you to act as a technical driver: helping teams solve complex engineering challenges, improving architecture, scaling processes, and ensuring that technical decisions lead to sustainable product growth.

What you’ll be doing

• Taking ownership of the technical strategy and architecture within the cluster.

• Collaborating closely with Engineering Managers, Product Managers, and other Staff Engineers to align technical solutions with business goals.

• Helping teams design scalable and maintainable solutions.

• Conducting technical reviews of critical changes and driving engineering best practices.

• Identifying technical risks and finding ways to mitigate them early.

• Mentoring senior engineers and raising the technical bar across the cluster.

• Participating in hiring and onboarding processes for senior engineers.

• Driving cross-team technical initiatives and improvements.

Technology stack

Ruby on Rails (7+), PostgreSQL, Docker, AWS infrastructure, Kubernetes; CI/CD with Jenkins and Gitlab, BitBucket.

Experience with Ruby is not required — we are happy to consider candidates from any backend background who are ready to learn Ruby on Rails in the first 3 months.

What we expect from you

• 10+ years of experience in backend development.

• Experience designing and evolving architecture in complex systems.

• A product mindset and understanding of how technical decisions impact business outcomes.

• Strong communication skills and ability to influence without authority.

• Experience driving cross-team initiatives and leading technical discussions.

• Passion for clean code, technical excellence, and knowledge sharing.

• Readiness to learn Ruby on Rails (if you don’t have experience yet).
