  • 5+ years of professional software development experience, with deep expertise in C++ and Linux/Unix environments.
  • Strong background in systems programming, performance engineering, and optimizing distributed systems.
  • Proven understanding of database internals or experience in other high-performance computing domains (e.g., real-time data, high-frequency trading).
  • Experience with debugging and profiling tools in production environments.
  • Ability to work autonomously in a distributed team setting and communicate effectively across technical and non-technical stakeholders.
  • Open-source contribution experience and a collaborative mindset in peer reviews and community engagement.
  • Passion for efficiency, scalability, reliability, and clean code practices.
  • Bonus: Experience with ClickHouse, Kubernetes, network programming (TCP/IP), cloud infrastructure, and public technical speaking or blogging.
  • Competitive salary based on location and experience
    • U.S. General Remote: $133,450—$197,200 USD
