Job description

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.

As a Senior 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.

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.

What you’ll do:

• Lead complex, cross-functional technical initiatives from conception to deployment.
• Work closely with product managers, designers, customers, and other engineers to ensure we deliver a high-quality experience.
• Drive the team's engineering standards, championing best practices in system design, code quality, testing, observability, and CI/CD pipelines to ensure we scale reliably.
• Solve complex, mission‑critical system problems with solutions that are scalable, maintainable, and resilient.
• Mentor and guide more junior team members, coordinate with other stakeholders and contribute to process improvements, raising the technical bar across the team.
• Communicate complex technical decisions and trade‑offs clearly, including their impact on system performance, reliability, and business outcomes.
• Partner cross‑functionally with teams including Sales, Marketing, and G&A to support product delivery and customer success.

Your experience:

• Strong understanding of and hands‑on experience with distributed systems and cloud services.
• 5+ years of experience developing and debugging system‑level software in languages similar to Golang or TypeScript.
• Track record of leading non‑trivial projects from design through production rollout, navigating ambiguity along the way.
• Strong communication skills with a passion for mentoring peers, fostering a collaborative team culture, and executing efficiently in a fast‑paced environment.
• Passion for building high‑quality products that are robust and easy to maintain in a fast‑paced, team‑oriented environment
• Bachelor's degree in Computer Science or equivalent practical experience.

Preferred Qualifications

• Experience building cloud‑native SaaS platforms.
• Experience working with frontend web frameworks like React.
• Prior experience mentoring engineers or leading technical projects.
