Description
Complexio is Foundational AI. This works to automate business activities by ingesting whole company data – both structured and unstructured – and making sense of it. Using proprietary models and algorithms Complexio forms a deep understanding of how humans are interacting and using it. Automation can then replicate and improve these actions independently.
Complexio is a joint venture between Hafnia, in partnership with Marfin Management, C Transport Maritime, Trans Sea Transport and BW Epic Kosan and SÃmbolo
We are looking for a Senior Engineer to establish and lead our new Developer Experience team. This team’s mission is to improve engineering productivity, consistency, and satisfaction by building and maintaining the systems, processes, and tooling that underpin our Software Development Lifecycle (SDLC).
You will shape how our engineers build, test, release, and monitor software, ensuring frictionless workflows while keeping ownership of business logic, test quality, and development practices firmly with the product engineering teams.
This is a hands-on role with significant influence: you will design systems, implement tooling, measure productivity gaps, and drive adoption of better practices across the engineering organisation.
Requirements
- 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).
What You Won’t Do
- Define test strategy, coverage, or quality gates (owned by engineering teams).
- Own microservice/domain documentation.
- Dictate coding practices (linting rules, frameworks, languages).
What We’re Looking For
- 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.
Benefits
- Join a pioneering joint venture at the intersection of AI and industry transformation.
- Work with a diverse and collaborative team of experts from various disciplines.
- Opportunity for professional growth and continuous learning in a dynamic field.
