Horizon3 · Remoto · United States
Join Horizon3 as a Staff Developer Experience Engineer, where you'll shape the way our engineers build, test, release, and operate software. In this hands-on technical leadership role, you'll define the architecture and roadmap for local development, CI/CD, build systems, and release workflows. You'll lead high-impact initiatives across engineering, establish sustainable practices, and improve developer workflow and delivery observability. You'll also mentor engineers, communicate complex technical decisions, and participate in design and operational reviews.
- Experience with container builds, Docker or OCI images, artifact repositories, and reproducible builds
- Experience mentoring engineers and influencing technical direction without relying on formal authority
- Deep experience designing and operating CI/CD systems, preferably GitLab CI/CD and self-hosted runners
- Strong understanding of software supply-chain security, dependencies, image vulnerabilities, provenance, secrets, and least privilege
- Strong understanding of Kubernetes-based development or delivery workflows

- Shared language/runtime base images, image signing, SBOMs, or provenance-control experience
- Internal developer platform, paved-road, service-template, or developer-portal experience
- Local Kubernetes, dev containers, Docker Compose, Orbstack, Skaffold, ArgoCD, or GitOps experience
- AI-assisted or agentic engineering workflow experience
- GitLab Runner fleets, CI optimization, build caching, or multi-repository release-system experience
