Senior Engineer - Developer Experience

Complexio is seeking a Senior Engineer to lead its Developer Experience (DevEx) team. The DevEx team is responsible for building and maintaining systems, processes, and tooling that underpin the company’s Software Development Lifecycle (SDLC). The role involves designing and implementing DevOps practices to improve engineering productivity, consistency, and satisfaction, with a strong emphasis on data-driven analysis and automation. It's a hands-on, impactful role with significant team leadership influence.

Requirements

• Own and operate CI/CD systems (GitHub Actions, runners, caching, artifact storage).
• Maintain stability, scalability, and cost-effectiveness of pipelines.
• Build and maintain systems for our monorepo.
• Ensure CI/CD observability with metrics flowing into Datadog/Slack.
• Measure and report on productivity gaps (e.g., build times, flakiness %, cost per run).
• Develop tooling for release notes, changelogs, packaging, and deployment.
• Standardise release processes across services.
• Enable customer-facing packaging and deployments, without owning release decisions.
• Identify friction in developer workflows through metrics, surveys, and incident data.
• Drive adoption of DevEx improvements by partnering with engineering teams and running enablement sessions.

Benefits

• Professional growth and continuous learning
