Site Reliability Engineer

The candidate will have responsibilities across the following functions:

Reliability and Engineering Excellence:

• Own and improve the reliability, availability, and performance of globally distributed, Kubernetes-based production systems.
• Define and continuously improve SLIs, SLOs, and SLAs using metrics derived from Prometheus and Grafana.
• Drive reliability best practices across the entire software development lifecycle.

Kubernetes and Platform Operations:

• Operate and scale production-grade Kubernetes clusters (EKS/GKE) running critical audio streaming and backend services.
• Troubleshoot complex production issues across pods, nodes, networking, storage, and the Kubernetes control plane.
• Implement autoscaling, rollout strategies, and resilience patterns for containerised workloads.

CI/CD and GitOps:

• Own and improve CI/CD pipelines using GitHub Actions and Jenkins to ensure safe, reliable, and repeatable deployments.
• Implement and operate GitOps workflows using Argo CD for Kubernetes application and configuration management.
• Enforce deployment best practices including canary, blue-green, and rollback strategies.

Observability and Monitoring:

• Build and maintain a strong observability stack using Prometheus (metrics), Grafana (visualisation), and Loki (logs).
• Design effective alerting strategies that reduce noise and improve signal quality.
• Use observability insights to drive performance tuning, capacity planning, and reliability improvements.

Incident Management and Operational Excellence:

• Lead and participate in incident response for platform, Kubernetes, and database-related issues.
• Perform post-incident reviews (PIRs) with clear root cause analysis and preventive actions.
• Improve on-call readiness, runbooks, and operational maturity for 24x7 global systems.

Databases and State Management:

• Support and improve reliability of MySQL in production, including monitoring, backups, failover, and performance tuning.
• Collaborate with backend teams on schema changes, query performance, and scaling strategies.

Infrastructure and Automation:

• Design and manage cloud infrastructure integrated with Kubernetes using Infrastructure-as-Code (Terraform).
• Automate operational tasks using Python and/or Go to reduce toil and improve system resilience.
• Drive cost and capacity optimisation across cloud and Kubernetes environments.

Collaboration and Innovation:

• Work closely with backend, mobile, data, product, and QA teams to embed reliability principles early.
• Contribute to Pocket FM's engineering roadmap with a focus on scale, resilience, and operational efficiency.
• Apply modern SRE and cloud-native best practices pragmatically in production.

Requirements:

• 3+ years of experience in Site Reliability Engineering or platform engineering roles.
• Proven experience operating large-scale, Kubernetes-based, consumer-facing systems.
• Strong hands-on expertise with Kubernetes in production environments.
• Experience with Prometheus, Grafana, and Loki for monitoring, alerting, and logging.
• Strong experience with CI/CD systems such as GitHub Actions and Jenkins.
• Hands-on experience with GitOps workflows using Argo CD.
• Solid experience managing and supporting MySQL in production.
• Strong experience with AWS and/or GCP.
• Proficiency in Python and/or Go.
• Strong Infrastructure-as-Code experience using Terraform.
• Solid understanding of Linux, networking, and cloud security fundamentals.
