What You Will Do

• Software Development: Design, build, and maintain scalable control plane services, operators, and custom controllers for Kubernetes

• Cluster lifecycle management: Develop automation including provisioning, upgrades, patching, and decommissioning.

• Monitoring and Observability: Implement and improve monitoring, alerting, and incident response systems to ensure optimal system performance and minimize downtime

• Internal tooling: Create workflows, tools, APIs, and command-line interfaces (CLIs) to empower customers and ML/AI teams to deploy and monitor inference services efficiently.

• Reliability: Design resilient systems capable of gracefully handling failures in large-scale distributed environments.

• Investigation: identify and resolve unique cluster issues at a low level, documenting findings for future reference.

• Incident Response: Participate in on-call rotations to respond to incidents and perform root cause analysis to prevent future occurrences

What We're Looking For

• Master’s degree in Computer Science, Engineering or a related field

• 5+ years of experience in a similar role (Software Engineer, DevOps, SRE ...)

• Strong coding proficiency (ideally Golang) and knowledge of software development best practices

• Mastery of containerization and orchestration tools (Docker, Kubernetes...)

• Exposure to site reliability issues in critical environments (issue root cause analysis, in-production troubleshooting, on-call rotations...)

• Experience working against reliability KPIs (observability, alerting, SLAs)

• Strong problem-solving abilities and attention to detail.

• Ability to own and deliver end-to-end features with minimal oversight.

• Excellent communication skills and collaborative attitude.

• Team-oriented, humble and eager to learn.

• Strong understanding of networking, security, and system administration concepts

Now, it would be ideal if you had experience with:
