About the Role

We’re looking for a Senior Systems Engineer to take direct ownership of the reliability, availability, performance, and observability of the production systems behind our portfolio of real-time sports data products. Reporting to the Chief Operations Officer, you’ll make sure our products run around the clock, delivering accurate, timely data to customers 24/7.

This is a hands‑on technical leadership role with plenty of autonomy.

What you’ll do

• Own reliability and performance
• Own the end‑to‑end operation, reliability, and performance of critical real‑time sports data systems, with a focus on functional correctness, high availability, low latency, and minimal downtime
• Take accountability for the 24/7 health of all products, keeping systems live and data flowing
• Investigate operational risks independently, make sound technical decisions, and drive problems through to resolution
• Set clear ownership and performance standards so reliability and service quality stay central to technical and business decisions

Lead observability and incident response

Prepare for the big moments

• Lead operational readiness reviews ahead of major events such as the FIFA World Cup, Super Bowl, Indian Premier League, and college football season
• Drive proactive capacity planning and performance forecasting aligned with the sporting calendar
• Work with the Infrastructure Team to optimise performance and cost efficiency across cloud and physical infrastructure

Document and collaborate

• Maintain and improve documentation covering system architecture, observability, diagnostics, and optimisation
• Create and maintain product‑specific runbooks, including incident response frameworks, escalation procedures, and repeatable recovery processes
• Work with Backend Developers and Data Acquisition Engineers to keep systems integrated and aligned with technical goals
• Collaborate with Client Support to investigate and resolve client‑impacting issues quickly
• Work with the CIO, CTO, and senior leadership to define operational priorities and ensure technology investment matches business and customer needs
• Champion a collaborative, accountable, improvement‑focused culture where incident learnings and performance data inform decisions

Metrics

• Sustaining 99.9% uptime for critical real‑time data services
• Meeting per‑product SLOs for availability and p99 end‑to‑end latency
• Scaling smoothly through traffic spikes during major sporting events
• Responding quickly to client‑related infrastructure issues
