## Description

Get to Know Us Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox" security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn-it-alls, committed to a culture of respect, collaboration, ownership, and results. As a remote first company, we require minimum 25Mbps consumer grade broadband connection. What You'll Do The Expert Engineer on the Image Build & Release team is the technical anchor for how NodeZero gets built and delivered to customer environments. NodeZero runs as a container in customer infrastructure — building that image correctly, delivering it reliably, and updating it safely across thousands of deployments is a hard systems problem with direct customer impact. You will set the technical direction for the build pipeline, the image signing and scanning strategy, and the OTA (over-the-air) delivery infrastructure that pushes updates to deployed NodeZero instances. This is a hands-on staff-level role. You will write code, produce architecture designs, mentor engineers, and own the most consequential technical decisions for how NodeZero is packaged and shipped. The team is building from a strong starting point — you will raise the bar on automation, reliability, and delivery velocity. This role reports to the Client Platform Engineering Manager and works directly with the OTA Services team on the delivery side. Responsibilities Build Pipeline Architecture: Design and own the CI/CD pipeline that produces NodeZero container images — from source to signed, scanned artifact ready for distribution Image Integrity & Security: Define the image hardening, CVE scanning, and signing strategy that ensures NodeZero images meet security and compliance requirements before they ship OTA Delivery Infrastructure: Partner with the OTA Services team to design the delivery mechanism that pushes image updates to customer-deployed NodeZero instances reliably and safely — including rollout strategy, rollback, and version pinning Release Engineering Standards: Set standards for build reproducibility, artifact versioning, and release gating that the full Client Platform team follows Mentorship: Mentor P4 engineers through code review, design review, and architectural pairing; be the person the team turns to when they hit a hard systems problem Operational Excellence: Own the build and release infrastructure end-to-end — on-call for pipeline failures, build time regressions, and delivery incidents What You'll Bring Build & Release Engineering 8+ years of professional software engineering experience, with deep specialization in build systems, CI/CD, or release engineering for containerized applications Expert-level knowledge of Docker and container image construction — multi-stage builds, base image selection, layer optimization, image hardening Experience with container image signing and verification (Cosign, Notary, or equivalent) and image scanning toolchains (Trivy, Grype, Snyk, or equivalent) Strong track record building and operating CI/CD pipelines at scale
