• Improve automation and engineering processes to support reliable and efficient delivery

• Work closely with engineers and other teams to understand customer needs and develop effective technical solutions

• Identify opportunities to improve our systems, processes and developer productivity

• Share knowledge and contribute to the development of the wider engineering team

• Take ownership of problems and outcomes while working collaboratively with colleagues across our global organisation

• Working knowledge of REST, GraphQL and/or gRPC

• Experience working with databases such as Postgres and/or MongoDB

• A strong understanding of software engineering fundamentals, including testing, reliability, maintainability and code quality

• A willingness to take ownership, contribute ideas and continuously improve

It would be great if you also have

• Experience working with high-volume data platforms or distributed data systems

• Experience with event-driven architectures and messaging systems

• Experience with authentication, authorisation, identity or entitlement systems

• Experience building systems that operate across cloud and edge environments

• Experience working with video, telemetry, sensor or time-series data

• Experience in a high-growth product or SaaS environment

You do not need to be a sports expert to be successful at Catapult. We are looking for great engineers who are interested in the problems we are solving.

What success looks like

In 6 months

You will have a strong understanding of our platform, architecture and engineering practices and will be confidently owning one or more Go microservices.

You will be shipping production changes across our backend services and contributing to areas such as our unified entitlement and licensing system, distributed data platform and authentication systems.

You will also have built strong relationships with the engineering team in Boston and colleagues across our global engineering organisation.

In 12 months

You will be leading the architectural design of a significant subsystem, taking a problem from initial design through to production across our Go service estate.

You will be contributing to how we evolve our federation patterns, offline-first edge architecture, data and entitlement models, as well as
