Principal DevOps Engineer

Principal DevOps EngineerCGI is seeking a Principal DevOps Engineer to lead the transformation of our enterprise build and release platform supporting CGI Advantage. Advantage Cloud Operations runs a build pipeline that takes a long time end to end. The Principal DevOps Engineer will own the full transformation: analyze the current pipeline, map every dependency, redesign the build architecture for speed and resilience, and deliver automated rollback. This is a hands-on engineering role with direct impact on release safety and customer outcomes. Location: This role can be performed from any of the US CGI office. Candidates should follow a hybrid schedule of 2–3 days onsite per week.Your Future Duties and Responsibilities:What You Will Own. Audit the current pipeline – instrument every stage, identify bottlenecks, and produce a dependency map. Redesign the pipeline architecture – parallelization, incremental builds, caching, artifact promotion, and environment reproducibility. Deliver automated rollback – every promotion gate must be reversible without manual intervention. Build resilience into the pipeline – flaky test isolation, retry policies, circuit breakers on external dependencies, and alerting when pipeline health degrades. Establish quality gates (unit, smoke, security scan, policy check) that block unsafe promotions without adding latency to the happy path. Document and hand off – every pattern, module, and decision is code reviewed, tested, and transferable to the wider team.Required Qualifications to Be Successful in This Role:What We Are Looking For. 10 + years in software engineering, DevOps, SRE, or Platform Engineering – you have rebuilt a slow, fragile pipeline before and can show the outcome. Deep hands-on expertise in GitHub Actions (or equivalent); you write pipelines as production code, not YAML copy paste. Strong grasp of dependency analysis – build graphs, artifact registries, incremental compilation, and test impact analysis. Proven experience designing automated rollback and blue green or canary promotion strategies in a multi tenant environment. Comfortable with Terraform, Kubernetes (AKS), and policy as code – you can trace a change from Git commit to running workload. Communicates trade offs clearly to both engineering teams and leadership; writes the design doc before writing the code. Success Criteria. Pipeline build time reduced to under 2 hours (incremental/ 4hrs full build) within six months. Automated rollback demonstrated and tested for all Advantage release tracks. Dependency map and build architecture documented and peer reviewed within 60 days. Zero manual steps required to promote or roll back a release by end of program.What You Can Expect from Us:Together, as owners, let's turn meaningful insights into action.
