Senior/Lead/Staff Ruby Engineer in Product Cluster

Who we're looking for:

We are seeking a talented and experienced Backend Engineer to join our R&D Team (250+ people: developers, QA engineers, designers, technical support engineers, DevOps engineers, and product managers). This role is key for us, and we are looking for someone with a proactive mindset, strong technical expertise, and readiness to take ownership of complex engineering challenges.
 

Technology stack:

• Backend: Ruby on Rails 7+, PostgreSQL
• Infrastructure: Docker, Kubernetes, AWS
• CI/CD & VCS: GitLab
   

Our expectations:

• Solid backend development experience (7+ years) in Ruby.
• Strong understanding of software architecture, design principles, and development methodologies
• Strategic thinking and proven ability to solve complex engineering problems
• Experience in improving code quality, introducing best practices, and setting coding standards
• Excellent communication and collaboration skills, ability to work effectively in cross-functional teams

What You’ll Be Responsible For:

• 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.

Samples of tasks solved by our developers:

• Development of Dropbox-like functionality — creation and maintenance of cloud file storage with collaborative access and synchronization features.
• Billing systems integration.
• Integration with third-party services.
