Senior Software Engineer

Salary: $61,000 - 101,000 per year Requirements: We need senior-level experience in performance engineering for distributed systems and/or production reliability engineering. We need a strong cloud and container background, particularly AWS with Kubernetes/EKS; ECS exposure is a plus. We need experience with modern observability platforms such as Datadog, Dynatrace, Grafana, OpenTelemetry, CloudWatch, or similar tools. Experience with KEDA and/or Karpenter is a significant advantage. Experience with Akamai is strongly preferred. We need someone who can lead through influence, mentor engineers, and collaborate effectively across teams. Responsibilities: We lead performance engineering initiatives, including load, stress, and soak testing, capacity modelling, performance tuning, and prevention of regressions through KPIs, guardrails, and acceptance criteria. We improve production readiness through observability, actionable alerting, incident triage, and root-cause analysis that results in lasting remediation. We strengthen resilience patterns such as timeouts, retries, circuit breakers, backpressure, rate limiting, graceful degradation, and failover preparedness. We drive safer releases by using canary and progressive delivery approaches, along with automated rollback patterns. We optimise containerised workloads across EKS as the primary platform and ECS or other compute environments where relevant, while improving autoscaling strategy and right-sizing.
