• Drive improvements in telemetry and observability , helping us move from log‑centric metrics to first‑class telemetry using OpenTelemetry and modern observability stacks.
• Optimise for performance , helping the platform scale for low‑latency, high‑throughput demands in real‑time sports data delivery.
• Mentor and guide engineers , promoting a strong DevOps culture and fostering collaboration across teams.
• Architect and implement solutions that span software and infrastructure, balancing resilience, scalability, and maintainability

What We’re Looking For

Essential

• Proven experience as a Senior or Principal Engineer in both software and DevOps contexts.
• Strong .NET software engineering background.
• Deep expertise in Kubernetes (on‑prem and cloud) and Terraform .
• Experience with real‑time, event‑driven systems and message brokers (e.g., RabbitMQ, Kafka).
• Strong grasp of telemetry, observability, and performance monitoring in distributed systems.
• Track record of technical leadership and setting engineering standards.

Nice to Have

• Experience with OpenTelemetry , Prometheus, Grafana, or similar observability tooling.
• Exposure to hybrid‑cloud or cloud migration strategies.
• Familiarity with performance optimisation in low‑latency data pipelines.
• Contributions to DevOps‑related communities, blogs, open source, or talks.

What You’ll Get

• The opportunity to shape the future of DevOps and Developer Experience within an innovative, high volume‑growth, data‑centric company.
• Freedom to influence architecture and tooling decisions.
• A collaborative, pragmatic engineering culture focused on excellence.
• A domain which offers continual learning opportunities and a plethora of engaging technical challenges.
