Job Description

Key responsibilities

  • Design and operate CI/CD pipelines for repository intake, build execution, image creation, artefact promotion, environment deployment, and evidence generation.
  • Implement release controls for private registries, package sources, signing, SBOM generation, vulnerability scanning, dependency provenance, and approval workflows.
  • Create observability across build systems, workflow services, repositories, test environments, model endpoints, and platform components using logs, metrics, traces, and dashboards.
  • Support troubleshooting of build failures, flaky pipelines, missing dependencies, environment drift, performance bottlenecks, and handover-readiness gaps.
  • Partner with software, SRE, testing, and security teams to define runbooks, operational KPIs, risk indicators, and audit-ready evidence packs for release decisions.

Examples of market tools, models, and platform components expected

  • CI/CD and release tools such as GitLab CI, Jenkins, ArgoCD, Tekton, GitHub Enterprise, Helm, Docker, Kubernetes, Kaniko, BuildKit, Nexus, Harbor, or Artifactory.
  • Security and supply-chain tooling such as Trivy, Grype, Syft, Cosign, SLSA-oriented controls, SBOM workflows, dependency scanning, secrets detection, and policy gates.
  • Observability stacks such as Prometheus, Grafana, Loki, OpenTelemetry, ELK/OpenSearch, Alertmanager, log aggregation, dashboarding, and automated health checks.
  • AI engineering integrations such as code-scanning workflows, model-backed log analysis helpers, documentation generators, internal model gateways, and workflow execution services.
  • Infrastructure automation using Terraform, Ansible, Helm, Python, Bash, GitOps patterns, private networks, controlled proxies, package mirrors, and secure secrets management.

Qualifications

  • 5+ years in DevOps, SRE, release engineering, platform operations, infrastructure automation, or secure build engineering roles.
  • Strong hands-on experience with CI/CD systems, Kubernetes-based delivery, container builds, private registries, artefact management, and release automation.
  • Practical knowledge of observability, incident response, operational dashboards, runbooks, SLA/SLO thinking, and troubleshooting distributed engineering environments.
  • Good understanding of software supply-chain security, SBOMs, image scanning, secrets handling, dependency provenance, and audit-ready release evidence.
  • Comfortable operating in confidentiality-sensitive programs where reproducibility, traceability, controlled access, and structured collaboration with engineering teams are essential.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
