Security Engineer (Full Stack)

Join Hadrian, a rapidly growing security team, as a Security Engineer (Full Stack). In this role, you will shape the security of our platform as we expand to serve external customers and partners. You will drive the transition to Factory-as-a-Service, with identity, multi-tenancy, and data boundaries at the core. This is a full-stack role that spans application code, cloud, Kubernetes, identity management, and cutting-edge operational technology on the factory floor. You will tackle challenges end-to-end, establish standards and best practices, and own security across the entire stack.

• Conduire la transition vers Factory-as-a-Service, en mettant l'accent sur l'identité, la multi-location et les frontières des données.
• Établir les normes, les meilleures pratiques et les outils qui permettront de faire évoluer la sécurité de l'entreprise.
• Posséder la sécurité de bout en bout sur l'ensemble de la pile — code d'application, infrastructure cloud, charges de travail Kubernetes, identité et autorisation.
• To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State
• If you’re curious, thrive in ambiguity, and want to chart new territory, this is your opportunity to make a lasting impact
• A track record of deleting controls or process — retiring the checks that shouldn't exist and proving the automated replacement held
• You weigh risk against innovation — and say so. You make the risk-aversion versus innovation trade-off explicit on real decisions, so the business chooses deliberately rather than defaulting to "no."
• Ship the fix, not just the finding. You write code (Go, Python, or similar) and solve problems by building the guardrails and tooling — SDKs, CLIs, CI/CD checks, and patterns — that make it easy to do the right thing and hard to do the wrong one, rather than filing a ticket for someone else
• 4+ years in security engineering, software engineering, or infrastructure/platform engineering, with real hands-on security ownership somewhere in there
• Fluency with agentic systems. Familiarity with agentic loops and task delegation — building with or on LLM agents and automation
• Genuine breadth and curiosity. You move between application security, cloud and Kubernetes security, identity/authorization, and networking — and you actively want to understand how a new layer works, down to the details
• You move fast and learn faster. You take an under-specified mission, decide where to start, make sound calls under uncertainty, and ramp on something unfamiliar quickly
• Security experience in manufacturing or OT environments
• GCC High administration or migration experience
• Familiarity with ITAR/EAR and CUI marking and handling requirements
• Ability to mentor and grow a team. As security scales here, you can set technical direction and level up the engineers who join around you
