About the role

Senior Engineering Manager leading the Client Platform team (Image Build & Release and OTA Services) responsible for NodeZero runner delivery in customer environments, including CI/CD, software supply chain security, and over-the-air updates.

Responsibilities

  • Build, mentor, and grow Client Platform to ~10 engineers across Image Build & Release and OTA Services. Directly manage the Engineering Managers of both sub-teams and set technical and cultural direction for the full org.
  • Lead end-to-end CI/CD workflows to create, sign, and reliably publish the NodeZero runner container image. Own software supply chain security: reproducible builds, image signing, SBOM generation, and vulnerability scanning in CI.
  • Architect and operate the over-the-air update delivery system that keeps NodeZero runners current across thousands of customer environments — reliably, securely, and without requiring manual customer IT intervention.
  • Collaborate closely with Security Research to ensure the runner enables new autonomous pentest capabilities as they ship.
  • Act as a Product Owner: Partner with product managers, security researchers, and customer success to manage the client-side roadmap.

Qualifications

  • Demonstrated expertise leading teams that design, build, and operate containerized software deployed into on-premise or customer-managed environments.
  • Experience implementing robust software supply chain practices — secure builds, image signing (cosign, Notary), reproducible builds, and vulnerability scanning in CI.
  • Experience designing and operating OTA update mechanisms for distributed agents or edge software at scale — including staged rollouts, rollback, and delivery verification.
  • Ability to reason about correctness in opaque, customer-controlled environments where you cannot observe failure modes directly.
  • Experience building or significantly growing an engineering team — including hiring, onboarding, and establishing engineering norms tailored for shipped software.
  • Proven ability to define and instill engineering culture: rigorous code review standards, robust testing across diverse customer environments, and a strong culture of ownership.
  • Proficient in Go (preferred), Python, or C++.
  • Strong Linux OS-level operations: container runtimes, networking in corporate environments, systemd, process isolation.
  • Experience with CI/CD pipelines for building and signing container images (cosign, Notary v2, or equivalent).
  • Familiarity with OTA update protocols and frameworks: TUF, Omaha, or custom mechanisms.
  • Understanding of TLS, certificate pinning, and secure software delivery in hostile network environments.
