Senior Performance Test Engineer with C# .NET Gatling and AWS required to own the end-to-end performance strategy across 8-10 product teams in a mature, BAU performance environment, with a clear mandate to take it further.
Key skills: C# .NET, Gatling, k6, JMeter, OpenTelemetry/Splunk APM/Prometheus/Grafana, AWS, CI/CD, SLI/SLO, distributed tracing, Spark MCP and agentic AI.
The in-house performance platform is built on Gatling with a C# wrapper. You will maintain and enhance it, troubleshoot independently using tracing and metrics, and coach engineers directly within product squads rather than managing a dedicated performance team.
Around half your time will be enabling teams; the rest split between platform ownership and actively exploring how AI tooling particularly agentic workflows using Spark MCP and GitHub MCP can reduce manual effort, accelerate issue detection, and shift performance left into CI/CD pipelines. Splunk is the current observability stack; experience with Prometheus, Grafana, or Kibana is transferable.
You don’t need to have delivered full agentic AI projects end-to-end, but you should be genuinely curious, self-directing, and able to put something tangible in front of teams quickly. This is not a coordinating role you’ll be expected to build, demonstrate, and drive.
Hybrid: 2 days on-site (Wednesday & Thursday).
