About the role
We’re looking for a Senior Platform Engineer to own the reliability of our platform and how we deliver software. Our entire platform runs on AWS, spread across multiple regions and dozens of accounts, so strong AWS experience at this scale is the core of the role. You’ll set company-wide standards for CI/CD and GitOps, and run Kubernetes on AWS in production. You’ll also keep the platform available, observable and resilient under real payment traffic. You’ll work closely with the Security and engineering teams, and you’ll help bring AI-driven tooling into how we build and operate systems.
What You'll Be Doing - Platform reliability. Keep the platform available, resilient and fast. Take part in incident management and the on-call rotation, and run blameless post-incident reviews.
- Infrastructure. Design, build and run our multi-region, multi-account AWS landscape and the EKS clusters on it. Manage infrastructure as code with Terraform, and manage AWS resources from Kubernetes with AWS Controllers for Kubernetes (ACK).
- CI/CD and GitOps strategy. Define company-wide CI/CD standards and design reusable pipeline templates. Maintain pipelines across 20+ repositories, and roll out GitOps and progressive delivery (canary, blue/green) with Argo CD.
- Governance and guardrails. Build security and compliance guardrails into the platform and delivery pipelines, together with the Security team.
- Observability. Improve monitoring, logging and alerting with VictoriaMetrics, Grafana, Loki, Zabbix, Splunk and PagerDuty. Define SLOs, SLIs and error budgets for critical services.
- Toil reduction. Build internal tooling and self-service so engineers do less manual work.
- AI in operations. Find and adopt AI-driven tools for delivery and operations, such as failure prediction and automated root cause analysis.
- Documentation. Write and maintain configuration standards, runbooks and architecture designs.
