• Be responsible for your code by writing automated tests, participating in code reviews, and supporting production systems.
• Help automate deployment, upgrades, and maintenance using modern DevOps tools and practices (CI/CD, containerization, telemetry, instrumentation).
• Occasionally provide on-call support for critical systems (we keep it reasonable).

• Solid experience with C/C++ on Linux and real-time systems.
• Practical experience in using IP-based protocols (TCP/IP, UDP, HTTPS, etc.).
• Familiarity with unit testing, especially using Google Test.
• Understanding of network protocols and distributed systems.
• Experience with cloud infrastructure and container orchestration.
• Strong problem-solving skills.
• Ability to work independently and communicate clearly.

• Hands-on experience with Python, Google Test framework, GitLab CI/CD, Kubernetes, or Terraform.
