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. You’ll spot weaknesses before they become outages, work closely with our Infrastructure, Backend, Data Acquisition, Scores, and Client Support teams, and help keep us running through evenings, weekends, and the biggest moments in the sporting calendar.

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

• Partner with the Infrastructure Team to design, implement, and continuously improve monitoring, observability, and fault-diagnostic practices

• Lead major incident management, including coordination, stakeholder communication, service recovery, and measures to limit customer impact

• Troubleshoot and resolve complex issues hands-on

• Be available for out-of-hours and weekend support to resolve critical incidents quickly

• Run consistent post-incident reviews, with root causes identified and corrective actions tracked through to completion

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

What you’ll bring
We’re looking for someone with the skills, experience, and mindset to thrive in this role. Ideally, you’ll have:

• Bachelor’s degree in Computer Science, IT, or a related field

• Proven experience as a Systems Engineer, Infrastructure Engineer, or similar in a high-volume, data-driven company

• Strong hands-on experience with a major cloud platform (AWS, GCP, or Azure) and server management

• Strong proficiency with Linux/Unix systems

• Scripting expertise in Python, Bash, or similar

• Experience with monitoring tools such as Prometheus, Grafana, or similar

• Good knowledge of scalable logging infrastructure for fault analysis, diagnostics, data quality, and performance monitoring and optimisation

• The ability to work in a cross-functional team and communicate clearly with developers, engineers, and non-technical colleagues

• Willingness to join out-of-hours and weekend support arrangements
