Job description

Sporting Solutions is a product led, technology-driven company that sources, generates, and distributes real-time sports betting data. Our systems operate under tight performance demands: low latency, high throughput, and ongoing reliability. We’re working to continually improve our platforms and are evolving our infrastructure and applications — including moving from legacy .NET Framework systems toward modern, containerised .NET 8/9 services running on Kubernetes in both on-prem and cloud environments.

About the Role

We are looking for a Principal Software Engineer with a DevOps mindset and deep software engineering experience, especially in .NET. This is a hands‑on, leadership role where you'll help shape the technical vision and engineering practices across the organisation. Leading through example and building Proof‑of‑Concept solutions to demonstrate improved practices will be key. You’ll work at the intersection of software architecture, DevOps strategy, and high‑performance infrastructure, driving forward our modernization efforts and improving how we build, deploy, monitor, and scale our systems.

What You’ll Do

• Define and shape our DevOps vision, working closely with senior engineering, infrastructure and existing DevOps teams.
• Lead our migration efforts from legacy .NET Framework apps to .NET 8/9, containerised and orchestrated with Kubernetes.
• Champion best practices in software delivery, CI/CD, observability, and infrastructure‑as‑code.
• 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

• 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.

What we offer

• Competitive annual leave package that increases with length of service + day off for your birthday!
• Hybrid working – 2 days a week in the office
• Company contribution to discounted gym scheme
• Vitality health care for you and your household
• Competitive yearly performance bonus
• Enhanced maternity and paternity leave
• Access to discounts for online shopping
• Cycle to work scheme
