We’re looking for an experienced backend engineer to help define and standardize modern service-oriented architecture at scale. This role combines hands-on development with solution design and setting best practices across engineering teams.


🎯 Your Responsibilities:

  • Design and build services in Python, Java, or Go.

  • Define consistent service communication architecture (REST, gRPC, GraphQL, OAuth 2.0 / OIDC).

  • Automate unit, integration, and contract tests, and set up CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI).

  • Implement observability tools (OpenTelemetry, Prometheus, Grafana).

  • Refactor existing services to improve performance and developer experience.

  • Contribute to technical documentation and integration standards (OpenAPI, Markdown).

  • Participate in architectural review boards and design workshops.

  • Collaborate closely with DevOps, frontend, and product teams.


📌 Requirements:

  • 5+ years of experience in designing and building backend services.

  • Proficiency in at least two of the following languages: Python, Java, Go.

  • Knowledge of OpenAPI, JSON Schema, CI/CD workflows, and contract testing.

  • Hands-on experience with microservices, Kubernetes, and service meshes (e.g., Istio, Linkerd).

  • Practical experience with both SQL and NoSQL databases (PostgreSQL, Redis, MongoDB).

  • Understanding of DORA metrics, SDLC, and software delivery best practices.

  • English level B2+ – ability to work in an international team and write/read technical documentation.


💡 What We Offer:

  • 100% remote collaboration (B2B).

  • Competitive salary.

  • Opportunity to influence technical decisions and architecture standards.

  • Work with a skilled team and modern tech stack.

  • Strong knowledge-sharing culture and engineering-first mindset.
