  • Own the lifecycle of backend services on GCP, ensuring resilience, performance and cost efficiency.
  • Design and implement OAuth2/OpenID Connect authentication and authorization solutions.
  • Contribute to event-driven architectures and highly concurrent backend systems.
  • Collaborate closely with engineering and platform teams to deliver secure and scalable solutions.
  • Mentor engineers and actively contribute to engineering best practices and technical excellence.
  • Drive automation initiatives to improve developer productivity and operational efficiency.
  • Stay up to date with modern backend and cloud technologies, sharing knowledge across teams.

Requirements:

  • Strong hands-on experience with Python (Django) and/or Node.js (Typescript/NestJS).
  • Experience building production-grade backend services and distributed systems.
  • Hands-on experience with GCP services.
  • Strong understanding of Infrastructure as Code and Terraform.
  • Experience designing scalable, secure and observable cloud-native architectures.
  • Solid knowledge of Kubernetes and containerized environments.
  • Understanding of Zero Trust and modern security engineering practices.
  • Experience with PostgreSQL performance optimization and event-driven architectures.
  • Strong engineering mindset with focus on automation, quality and operational excellence.
  • Ability to work effectively in cross-functional and international engineering teams.

Nice to have:

  • Experience with Go or Rust.
  • Contributions to open-source projects, technical blogging or public GitHub portfolio.
  • Broad full-stack understanding with backend specialization.
  • Passion for solving complex engineering and security challenges at scale.

What we offer:

  • Opportunity to work on strategic, global cybersecurity and cloud engineering initiatives.
  • Collaboration with highly experienced international engineering teams.
  • Long-term cooperation within a stable enterprise-scale environment.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
