Security Engineer, Full Stack

Hadrian

Los Angeles, CA 90011

Health InsuranceRetirement Benefit

4+ years in security engineering, software engineering, or infrastructure/platform engineering, with real hands-on security ownership somewhere in there.
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.
Fluency with agentic systems. Familiarity with agentic loops and task delegation - building with or on LLM agents and automation
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
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."
A track record of deleting controls or process - retiring the checks that shouldn't exist and proving the automated replacement held.
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.
