Developer Experience CX

Job Description

CI/CD Infrastructure & Tooling

• 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.

Pipeline Instrumentation & Optimisation

• Analyse pipelines for inefficiencies (e.g., flaky tests, redundant steps, lack of caching).
• Recommend and implement optimisations (parallelisation, test selection, caching strategies).
• Define benchmarks and KPIs (e.g., build times, flakiness %, cost per run).
• Measure and report on productivity gaps (e.g., time lost to flaky tests, slow builds, manual release steps).

Onboarding & Documentation

• Maintain up-to-date documentation on SDLC processes, CI/CD, release flows, and GitHub usage.
• Provide templates, playbooks, and starter kits.
• Automate repetitive onboarding processes.

GitHub & SDLC Guardrails

• Own GitHub governance (branch protections, repo standards,
• integrations).
• Implement base SDLC guardrails (PR templates, code owners, security scans).
• Ensure compliance requirements are integrated into pipelines.

Monitoring & Incident Flow

• Set up alerts for pipeline health regressions.
• Provide first-level triage to distinguish infra vs. test vs. dependency issues.
• Escalate to the correct engineering team and ensure test ownership is tracked.

Release Management Support

• Build tooling for release notes, changelogs, packaging, and
• deployment.
• Standardise release processes across services.
• Enable customer-facing packaging and deployments, without owning release decisions.

Change Management & Adoption

• Identify friction in developer workflows through metrics, surveys,
• and incident data.
• Drive adoption of DevEx improvements by partnering with engineering teams, running enablement sessions, and monitoring uptake.
• Establish feedback loops to validate impact (e.g., reduced build times, improved developer satisfaction).

Qualifications

• 3 - 5+ years of experience DevEx Engineer.
• Proven experience with CI/CD platforms (e.g., GitHub Actions, GitLab CI, CircleCI).
• Strong background in SDLC practices and developer productivity tooling.
• Hands-on experience with infrastructure automation (e.g., Docker, Kubernetes, IaC with Terraform, Ansible or Pulumi).
• Familiarity with observability & monitoring (Datadog, Prometheus, or similar).
• Experience managing or improving monorepo build systems.
• Strong ability to measure developer productivity gaps and define KPIs.
• Experience in driving adoption of change in engineering
• organisations.
• Excellent communication skills and a collaborative mindset.

Nice to have

• Experience in release engineering or building developer-facing platforms.
• Background in Software Engineering, SRE or infrastructure engineering, with a strong developer tooling focus.
• Knowledge of compliance-driven SDLC requirements (e.g., ISO 27001, SOC2).
• Experience running developer surveys, DX metrics frameworks (e.g., DORA, SPACE), or feedback-driven adoption programs.
