THE ROLE

This role suits Backend Engineers who aren't afraid to jump in and shape the DevOps stack.

• Assess complexity, outline risks, and estimate effort and timelines.
• Rebuild or refactor backend/cloud components when needed, including rewriting services (with AI assistance).
• Utilize AI tools and agents to speed up research, refactoring, documentation, and investigations (Claude, Cursor and more).
• Design and maintain cloud environments using Infrastructure as Code (Terraform preferred) mainly for GCP, AWS and Azure.
• Build, maintain, and improve CI/CD pipelines.

Hiring manager: Igor Yakunin

Must-have:

• 5+ years Backend Engineering.
• Hands-on experience with GCP or strong AWS/Azure background and willingness to transition.
• Practical experience with Terraform (or similar IaC).
• Strong Linux, networking, and cloud fundamentals.
• Experience with Docker and containerized deployments.
• Proficiency in at least one backend language (Python, Node.js, Go, Java, etc.).
• Experience with SQL and/or NoSQL databases.

Nice-to-have:

• Experience with Kubernetes or other orchestration tools.
