Senior SRE Engineer

Stack

Responsibilities

• ▹Define, instrument and report on SLIs, SLOs and error budgets across critical services, so reliability decisions are driven by data rather than opinion
• ▹Own observability end-to-end (metrics, logs, traces, dashboards and alerting) and drive measurable reductions in detection and resolution times
• ▹Reduce alert noise and false positives so on-call engineers can trust what wakes them up
• ▹Run reliability reviews and an error-budget policy that shapes how teams prioritize between shipping and stability
• ▹Operate, scale and upgrade the multi-cluster Kubernetes (GKE) environment: cluster lifecycle, autoscaling, networking, ingress and resource management
• ▹Act as the deep-expertise escalation point for cluster and platform issues across dozens of services
• ▹Own capacity planning, performance and cloud cost efficiency, balancing spend against reliability targets
• ▹Build self-service platform tooling that lets product teams move quickly without needing to become infrastructure experts
• ▹Embed security into the platform through RBAC and least-privilege, secrets management, image and dependency scanning, network policies and a disciplined patching cadence
• ▹Partner with the security function on vulnerability remediation, audit readiness and secure-by-default infrastructure
• ▹Own disaster recovery: define and regularly validate RTO/RPO targets through DR drills and failure testing
• ▹Contribute to architecture and production-readiness reviews so reliability and security are designed in
• ▹Lead the on-call rotation and act as incident commander during production incidents
• ▹Run blameless postmortems, quantify impact and track corrective actions through to closure
• ▹Build and maintain Infrastructure as Code (Terraform) and CI/CD pipelines, enforcing GitOps and progressive delivery with automated rollbacks
• ▹Systematically identify, measure and eliminate operational toil through automation
• ▹Within the first 12 months, establish shared measurement with the Security team (vulnerability remediation times, patching cadence and coverage, access review completion, security incident detection and response times) and a single agreed view of operational health across engineering and security
• ▹Connect platform performance to the business it supports: the reliability of the marketing and growth stack, the speed and safety of the path from commit to production, and the infrastructure cost behind serving and acquiring users

Requirements

• ▹Experience operating high-traffic, always-on production systems at meaningful scale, typically gained over 5-8 years in SRE, Platform or DevOps roles
• ▹Hands-on production Kubernetes experience: you have run clusters day to day, through upgrades, autoscaling and real troubleshooting under load
• ▹A strong cloud engineering background, along with solid Linux and networking fundamentals
• ▹A track record of defining and operating with SLOs and error budgets, and comfort being measured on reliability outcomes
• ▹Experience with Infrastructure as Code and CI/CD pipeline design
• ▹Depth in observability tooling: instrumentation, dashboarding and alert design
• ▹A genuine security-first mindset, where least-privilege, secrets hygiene and vulnerability management are habits
• ▹Scripting and automation fluency in at least one language, used to build tooling and remove toil
• ▹Incident-command experience: owning on-call, running blameless postmortems and driving resolution times down over time
• ▹Ability to communicate clearly with both engineers and leadership, especially under pressure

Nice to have

• ▹Experience with high-scale consumer or mobile app backends, or with AI/ML inference workloads and their scaling characteristics
• ▹Experience with GitOps and progressive-delivery patterns such as canary and blue-green rollouts
• ▹Familiarity with service mesh, API gateways, or multi-region and multi-cluster topologies
• ▹Cloud cost optimization and FinOps discipline at scale
• ▹Exposure to compliance initiatives (SOC 2, ISO 27001, GDPR) and broader DevSecOps practice
• ▹Chaos engineering or resilience testing experience
• ▹Relevant certifications in Kubernetes, cloud or DevOps disciplines
• ▹Experience supporting many independent services and teams concurrently in a fast-shipping, product-led environment
