Zusammenfassung

Horizon3.ai, a remote cybersecurity company, seeks an Expert Engineer for the OTA Services team to scale NodeZero updates across thousands of deployments, including air-gapped environments. You will design and implement the update delivery, version management, and rollback mechanics, mentoring P4 engineers and collaborating with the Image Build team to ensure reliable artifact delivery.

You will tackle architecture, rollout strategies, and constrained-environment delivery, ensuring security and

Qualifikationen

• 8+ years of professional software engineering experience with deep specialization in distributed systems, remote update systems, or fleet management infrastructure.
• Deep understanding of remote update system design — delivery protocols, version negotiation, delta delivery, health verification, and rollback semantics.
• Experience designing rollout strategies for software deployed across heterogeneous, customer-managed environments — you understand the difference between a lab rollout and rolling something out to thousands of production deployments you don't control.
• Strong proficiency in Go, Python, or Rust for systems-level infrastructure work.

Aufgaben

• OTA Architecture: Design and own the over-the-air update system — the delivery protocol, version negotiation, rollout orchestration, health verification, and automatic rollback
• Deployment Fleet Management: Own the systems that track the version state of every NodeZero deployment — know what's running where, what's pending, and what's stuck
• Rollout Strategy: Design safe rollout strategies for updates — phased rollouts, canary deployments, customer pinning, and emergency hold mechanisms
• Constrained Environment Delivery: Design delivery mechanisms that work reliably across diverse customer environments including air-gapped networks, strict egress policies, and minimal-footprint deployments
• Reliability & Incident Response: Own OTA system reliability end-to-end — on-call for delivery failures, stuck updates, and version drift incidents
• Mentorship: Mentor P4 engineers through design review, code review, and technical pairing; be the person the team turns to when delivery semantics get complicated
