• You'll develop observability capabilities, enabling proactive monitoring and faster incident resolution.


• You'll facilitate incident management, driving root cause analysis and continuous improvement.


• You'll collaborate with engineering teams to embed reliability, resilience, and performance into every stage of delivery.

We're looking for these essential skills

• Software engineering and design experience (preferably .net/C\#), to build and improve production systems, apply solid design principles, and contribute directly to codebases to deliver reliable, scalable, and maintainable services.


• The ability to automate infrastructure, operational processes, and deployments using modern engineering practices.


• Experience building effective observability solutions, including monitoring, logging, alerting, and tracing.


• Strong problem\-solving skills with the ability to diagnose and resolve complex production issues.


• The ability to influence technical decisions and collaborate effectively across engineering and business teams.

It's a plus if you also have these skills

• Experience operating Kubernetes\-based platforms at scale.


• Knowledge of Infrastructure as Code tools and cloud platform services.
