Cybersecurity Incident Response Lead

Description: Reusable launch systems depend on secure, resilient information systems. As a Cybersecurity Incident Response Lead, you will lead the detection, investigation, containment, and recovery of cybersecurity incidents affecting Stoke’s infrastructure, engineering environments, manufacturing systems, and sensitive aerospace data. This is a hands‑on technical leadership role with ownership of incident response readiness and execution. You will lead complex investigations, coordinate response across teams, and translate findings into practical improvements that reduce risk and strengthen our ability to respond. You will provide technical direction and mentorship while working closely with IT, security, software engineering, manufacturing, and operations. We are a small, highly motivated team. You will balance decisive response with operational safety and continuity, keeping technical teams and leadership informed as incidents evolve. You must be ready to stay focused, move fast, self‑direct, and learn on the fly.
