This is your opportunity to make an impact through precision, collaboration, and innovation — delivering trusted infrastructure that drives real-world outcomes.

We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee.

Join us and you’ll be part of an open, friendly community of experts. We’ll train and support you in taking your career wherever you want it to go.

Monitor & Diagnose: Analyse logs and telemetry via Prometheus, Grafana, or ELK to detect anomalies and inform continuous improvement. Collaborate & Document: Work with platform engineers and SREs to define coverage, maintain traceability, and capture results for release assurance.
