Staff Developer Experience Engineer (Developer Experience)

Horizon3 as a Senior or Staff Developer Experience Engineer.

Responsibilities

• In this hands-on technical leadership role, you will shape how our engineers build, test, release, and operate software.
• You will define the architecture and roadmap for local development, repository tooling, CI/CD, build systems, and release workflows.
• You will lead high-impact initiatives across engineering, build reusable GitLab CI/CD templates, and establish sustainable practices for shared container images and build performance.
• You will also mentor engineers, communicate complex technical decisions clearly, and participate in design and operational reviews.
• Definir la arquitectura y la hoja de ruta para el desarrollo local, las herramientas de repositorio, CI/CD, los sistemas de construcción y los flujos de trabajo de lanzamiento.
• Liderar iniciativas de alto impacto en toda la ingeniería que reduzcan la coordinación manual y estandaricen el camino desde el cambio de código hasta la producción.
• Construir plantillas reutilizables de GitLab CI/CD, capacidades de ejecutores, flujos de trabajo de desarrolladores, puertas de prueba, promoción de artefactos, manifiestos de lanzamiento y caminos de reversión.
• Experience with container builds, Docker or OCI images, artifact repositories, and reproducible builds

Requirements

• 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
• 8+ years of experience in Developer Experience, Developer Productivity, Build/Release Engineering, Platform Engineering, SRE, DevOps, or software engineering with substantial tooling and delivery ownership
• Proficiency in Go and Python for automation, developer tooling, or platform services
• Demonstrated success leading complex initiatives across multiple teams and driving adoption of shared capabilities
• Excellent written and verbal communication skills
• Experience implementing automated tests, security checks, release gates, progressive delivery, and rollback

Preferred

• Experience mentoring engineers and influencing technical direction without relying on formal authority
• 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
• OpenTelemetry, Datadog, pipeline telemetry, or developer-productivity metrics experience
• Security-sensitive, regulated, or cybersecurity experience
• Exact tool matches are less important than strong software-engineering fundamentals, platform judgment, empathy for developers, and a track record of improving delivery systems at scale
