You’ll partner closely with engineering teams to evolve our platform architecture, improve reliability, and accelerate delivery through automation, observability, and thoughtful system design.

Key Responsibilities

• Build and evolve multiple distributions of Kubernetes platform.

• Build automation and tooling to streamline deployments, configuration, and environment management.

• Drive reliability practices such as SLOs, error budgets, incident responses, and post‑incident reviews.

• Develop golden paths for service onboarding, CI/CD, and platform usage across all K8s variants.

• Implement observability systems including metrics, logging, tracing, and alerting.

• Collaborate with product and engineering teams to ensure platform capabilities meet evolving needs.

• Optimize performance and capacity across compute, storage, and networking layers.

• Champion infrastructure-as-code and modern cloud‑native patterns.

• Drive automation-first operations using IaC and Git Ops.

• Lead incident response, RCA, post-incident learning, and improve on-call health.

• Partner with security teams to enforce platform guardrails, policy, and secure defaults.

• Lead complex troubleshooting efforts across distributed systems and production environments.

• Mentor engineers and contribute to a culture of operational excellence.

Required Qualifications

• 8+ years in SRE, DevOps, or platform engineering with hands‑on ownership of production systems.

• Expertise in Kubernetes and container orchestration at scale.

• Proficiency with IaC tools such as Terraform, Ansible, and CloudFormation.

• Solid programming skills in languages such as Go, Python, or Bash.

• Deep understanding of distributed systems, networking, and Linux internals.

• Experience building CI/CD pipelines using tools like Gitlab runners, GitHub Actions, or Jenkins.

• Strong observability background with Prometheus, Grafana, Open Telemetry, or similar.

• Proven track record of incident management and improving system reliability.

Preferred Qualifications

• Experience designing internal developer platforms or platform‑as‑a‑product models.

• Experience in Open Shift, Titan‑k8s and Robin.

• Knowledge of event‑driven architectures and streaming systems like Kafka.

• Security engineering familiarity including secrets management and compliance frameworks.

• Contributions to open‑source projects in the cloud‑native ecosystem.

• Strong experience with cloud platforms such as AWS, Azure, or GCP.

What Success Looks Like

• A stable, scalable platform that accelerates developer productivity.

• Reduced operational toil through automation and self‑service tooling.

• Clear reliability metrics that guide engineering decisions.

• Faster, safer deployments with strong CI/CD foundations.
