Senior Software Engineer (YDB Team)
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer (YDB Team) based in United Kingdom.
This is an opportunity to work on highly scalable infrastructure powering demanding AI and cloud workloads.
You will contribute to an open-source distributed database and storage platform at the heart of critical cloud services.
The role focuses on solving complex systems challenges through high-performance C++ engineering and advanced optimization.
- You’ll work with modern hardware, including high-speed networking, NVMe storage, and data processing accelerators.
- Your work will directly influence performance, reliability, scalability, and efficiency across production-grade infrastructure.
- You’ll collaborate with experienced engineers in an international, fast-moving environment where technical ownership is encouraged.
This is a hands-on role for someone excited by low-level systems, distributed computing, and building infrastructure for the future of AI.
Accountabilities
- Develop and optimize YDB components to take full advantage of modern hardware, including QLC NVMe drives, high-bandwidth network adapters, and DPUs.
- Improve performance across widely used storage technologies, including HDDs and TLC NVMe devices.
- Reengineer system components using more efficient algorithms to address complex scalability, performance, and reliability challenges.
- Design and implement high-performance, low-latency software components for heavily loaded production systems.
- Analyze system behavior and identify performance bottlenecks using profiling, debugging, and diagnostic techniques.
- Work on distributed storage and database infrastructure supporting demanding AI and cloud workloads.
- Contribute to the reliability, availability, and durability of production-grade distributed systems.
- Participate actively in incident investigation and resolution, helping identify root causes and implement lasting improvements.
- Collaborate with engineers across infrastructure, storage, networking, and AI-focused teams to deliver robust technical solutions.
- Contribute to an open-source codebase and participate in technical discussions, design decisions, and continuous improvement.
- Take ownership of engineering challenges from investigation and design through implementation, optimization, testing, and production deployment.
