Nice to have: * Prior experience working in dual-use, Defense, Government, Cyber Security, or Regulated Enterprise environments. * SC or DV clearance eligibility in the UK. * Experience with cryptographic key management (Vault, KMS) and code-signing infrastructure. * Familiarity with zero-trust networking tools and Kubernetes security operators (Cilium, Istio, Kyverno, SPIRE). ## Description As a Release Engineer at Valarian, you will own the delivery pipelines and release lifecycle for Acra-ensuring our hardened platform can be deployed reliably, predictably, and securely across cloud-native, on-premise, and strictly air-gapped environments. Releasing software at Valarian is not a typical SaaS continuous deployment pipeline. Because Acra operates as an enclave citadel in high-consequence environments (defense, government, and highly regulated enterprise), our releases must meet strict cryptographic verification, zero-trust integrity, and reproducible build standards. You will build and maintain the secure build systems, artifacts, release tooling, and deployment automation that allow engineering teams to ship high-velocity code without compromising security, compliance, or operational resiliency. What you'll do: * Own the Release Lifecycle: Build, maintain, and optimize CI/CD pipelines and release engineering tooling for the Acra platform stack across multiple environments (multi-cloud, hybrid, on-prem, and air-gapped). * Architect Air-Gapped & Offline Packaging: Design reproducible, self-contained release artifacts (Helm charts, container images, binary bundles) capable of deploying seamlessly into environments with zero internet connectivity. * Enforce Software Supply Chain Security: Implement cryptographic signing (e.g., Sigstore/Cosign, SLSA provenance), Software Bill of Materials (SBOM) generation, and automated vulnerability gating across all build pipelines. * Automate Infrastructure-as-Code (IaC): Maintain release-side IaC and GitOps delivery frameworks (ArgoCD, Flux, Terraform) to ensure target environments maintain consistent posture and deterministic updates. * Streamline Developer Velocity & Reliability: Partner closely with platform, security, and application engineering teams to standardize versioning, branching strategies, and automated testing feedback loops. * Drive Release Readiness & Auditability: Ensure every Acra platform release produces immutable audit trails, change logs, and evidence artifacts required for government and commercial compliance standards. ## Related Videos - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Rate-limiting using eBPF and Istio: How to protect your SaaS customers from themselves](https://www.wearedevelopers.com/videos/100220-rate-limiting-using-ebpf-and-istio-how-to-protect-your-saas-customers-from-themselves) - [Enabling automated 1-click customer deployments with built-in quality and security](https://www.wearedevelopers.com/videos/83-enabling-automated-1-click-customer-deployments-with-built-in-quality-and-security) - [Next-gen CI/CD with Gitops and Progressive Delivery](https://www.wearedevelopers.com/videos/1603-next-gen-ci-cd-with-gitops-and-progressive-delivery) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Events like RSAC Get You CISOs.
