- Strengthen the development and reliability of deployment pipelines that deliver builds to internal teams, QA and external platforms, ensuring consistent and repeatable releases across all target destinations.
- Design, build and maintain backend services such as build storage infrastructure, symbol servers, archiving systems and dashboards, ensuring they scale with studio demand.
- Write and review production-ready code, primarily in C++ and C#, setting expectations for quality, maintainability and testing.
- Join the rotating weekly support responder role to triage build/test issues across all infrastructure channels.
- Establish key metrics and dashboards that surface issues early, track reliability trends, and demonstrate measurable improvement over time.
- Identify bottlenecks in hardware utilisation, storage strategy, CI capacity, and build roadmap to address them.
- Support other engineers, contributing to knowledge sharing, documentation, and improved engineering practices.
- Work with the test automation team to integrate comprehensive quality gates into CI workflows, ensuring fast and actionable feedback for development teams.
What we are looking for
- Strong experience designing, operating and improving build systems, CI/CD pipelines or DevOps platforms at scale.

- Experience with console automation (PS5/Xbox).
- Experience with online store APIs (e.g. Steam/MS).
- Familiarity with Perforce or similar version control systems in large team environments.
- Familiarity with branching strategies and their application in large-scale, multi-project environments.
- Strong communication skills, with the ability to influence across disciplines and engineering leadership.
- Comfortable balancing hands-on technical work with broader architectural thinking.
Desirable
- Experience with hardware build farms, build node provisioning and cost-effective on-prem resource management.
- Strong understanding of build storage, archiving strategies and performance constraints.
- Experience with large-scale CI environments.
- Experience in improving tooling UX, dashboards, and workflow automation.
