Job description
As a Security Engineer at Hadrian, you’ll shape the security of our platform as we expand to serve external customers and partners
You’ll drive the transition to Factory-as-a-Service, with identity, multi-tenancy, and data boundaries at the core
This is a full-stack role—spanning application code, cloud, Kubernetes, identity management, and cutting-edge operational technology on the factory floor
You’ll work with innovative systems, some being developed here for the first time, including manufacturing and OT environments that few security engineers have encountered
Join us as a founding member of a rapidly growing security team
Instead of inheriting legacy choices, you’ll establish the standards, best practices, and tools that will scale our security from the ground up
You’ll tackle challenges end-to-end—learning unfamiliar systems and designing solutions that make secure practices the default
Own security end-to-end across the whole stack — application code, cloud infrastructure (AWS/GCP), Kubernetes workloads, identity and authorization, and the factory-floor and operational-technology systems that produce real parts
Scale security through automation. Build the agentic tooling and automation loops — AI-driven checks, paved-road patterns, self-enforcing guardrails — that let coverage grow with what you build rather than with headcount
Dig into unfamiliar systems — new tech we’re adopting and manufacturing systems few people understand — map how they actually work, identify where the real risk lies, and design controls that fit the way Hadrian builds
Turn compliance into engineering. Build the practical foundations for CMMC 2.0 / NIST 800-171 and the ITAR boundary as controls that hold up under audit — not paperwork beside the system
Respond when it matters. Investigate, contain, and drive incidents to resolution, then turn each one into a systemic fix and a better default
Benefits
Relocation stipend if you’re moving from outside of LA
100% coverage of platinum medical, dental, vision, and life insurance plans for employees
401k
Flexible vacation policy
Eligibility & Requirements
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
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
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
A track record of deleting controls or process — retiring the checks that shouldn’t exist and proving the automated replacement held
Fluency with agentic systems. Familiarity with agentic loops and task delegation — building with or on LLM agents and automation
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.”
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
Security experience in manufacturing or OT environments
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
GCC High administration or migration experience
