Senior Site Reliability Engineer - Infra Ops

• Design, build, and operate Kubernetes platforms that provide secure, highly available, and scalable foundations for critical production services across hybrid and public-cloud environments.

• Build infrastructure as code with Terraform, creating reusable modules, safe delivery workflows, and well-governed infrastructure changes.

• Develop backend services, internal tools, and operational automation in Go, Python, or JavaScript/TypeScript to eliminate manual work and improve the developer experience.

• Partner with engineering and product teams to understand workload requirements and design pragmatic solutions for reliability, performance, capacity, security, and cost.

• Improve the production lifecycle through reliable CI/CD, deployment automation, progressive delivery, and clear operational ownership.

• Define and evolve observability practices across metrics, logs, traces, alerting, and dashboards so teams can detect issues early and troubleshoot effectively.

• Own production reliability by participating in on-call, leading incident response, performing root-cause analysis, and driving blameless postmortems and durable corrective actions.

• Establish and maintain reliability targets through meaningful SLIs, SLOs, error budgets, capacity planning, disaster-recovery testing, and resilience improvements.

• Embed security and compliance into platform operations, partnering with Security to protect infrastructure, workloads, and data while meeting applicable regulatory requirements.

• Apply AI-assisted and data-driven operational techniques to improve signal detection, reduce alert noise, accelerate root-cause analysis, and surface opportunities for automation.

• Raise the bar for the team through thoughtful code reviews, documentation, knowledge sharing, and mentorship.

• Mentor and support team growth , fostering collaboration and scalability.

• 5+ years of experience in Site Reliability Engineering, DevOps, Infrastructure Engineering, or a closely related software engineering role supporting production systems.

• Deep, hands-on Kubernetes expertise: designing, operating, securing, and troubleshooting production clusters and containerized workloads at scale.

• Strong Terraform experience, including authoring reusable modules, managing state and environments, and delivering infrastructure changes through reviewable, automated workflows.

• Production software-development experience in Go, Python, or JavaScript/TypeScript, with the ability to build maintainable backend services, tooling, and automation - not only scripts.

• Demonstrated success improving the reliability, performance, scalability, or cost efficiency of distributed systems in production.

• Experience with cloud infrastructure and core networking concepts, including IAM, DNS, load balancing, routing, service networking, and secure connectivity.

• Strong observability and troubleshooting skills using metrics, logs, traces, alerting, and incident data to diagnose complex systems.

• Experience defining and operating against SLIs, SLOs, error budgets, incident-management processes, postmortems, and disaster-recovery practices.

• Familiarity with CI/CD, GitOps or deployment automation, and safe rollout strategies such as canary or blue-green deployments.

• A security-minded approach to infrastructure and a track record of partnering effectively with Security and engineering teams in regulated or high-availability environments.

• Clear written and verbal communication, strong ownership, and the judgment to balance speed, risk, and operational excellence.

• Experience applying AI-assisted tooling to engineering or operations workflows is a plus.
