About the role

<p><strong>Position Summary</strong></p> <p>SingleStore engineers build the real-time data platform that enables some of the world's most demanding applications. Our cloud-native database architecture enables high-performance transactional and analytical workloads at scale.</p> <p>As a Senior or Principal Software Engineer on the Managed Service (Helios) team, you will build and own release-defining projects at the intersection of distributed systems, cloud infrastructure, networking, and database technology. Helios runs thousands of SingleStore clusters across AWS, Azure, and GCP — autonomously deployed, scaled, secured, and healed on top of Kubernetes — operating at the frontier of multi-cloud, multi-region, multi-tenant, low-latency, always-on systems. You will work across the control plane, the data plane, the operator, networking, storage, and the customer portal, with true end-to-end ownership.</p> <p>Note: This role is open across multiple levels. Final leveling (Senior, Staff, or Principal) will be determined based on experience, scope of impact, and demonstrated technical leadership throughout the interview process.</p> <p><strong>What you'll do:</strong></p> <ul> <li>Lead technical design and decision-making for large, release-defining projects impacting SingleStore's cloud platform, spanning distributed systems, cloud infrastructure, and database technology.</li> <li>Design and implement new capabilities across networking, control plane, and managed service infrastructure, including multi-cloud and multi-region architecture, secure connectivity, identity, and storage.</li> <li>Solve complex, mission-critical system problems with solutions that are scalable, maintainable, and resilient — covering consistency, availability, performance, isolation, security, and cost across thousands of tenants on shared and dedicated infrastructure.</li> <li>Investigate, debug, and fix issues in the cloud — diagnosing elusive distributed-systems bugs, noisy-neighbor regressions, and subtle cross-cloud asymmetries in production.</li> </ul> <h4><strong>Your Experience:</strong></h4> <ul> <li>Strong understanding of and hands-on experience with distributed systems and cloud services.</li> <li>4+ years of experience developing and debugging system-level software in languages similar to Golang, C++, or Rust (more for Principal).</li> <li>Bachelor's degree in Computer Science or equivalent practical experience.</li> <li>Demonstrated ability to design and build highly reliable, high-performance system software.</li> <li>Track record of leading non-trivial projects from design through production rollout, navigating ambiguity along the way.</li> </ul> <p><strong>Preferred Qualifications</strong&gt
