## About the Role

* Strong software engineering skills and comfort shipping production code (e.g., .NET, Python, Java, etc.).
 * Solid integration experience: REST APIs, JSON, authentication flows, troubleshooting logs, and operational debugging.
 * Experience automating workflows (CI/CD, scripting, build/release pipelines, developer tooling).
 * A builder mindset: you like turning messy security problems into repeatable, scalable engineering solutions.

Nice-to-have (not required)

 * Exposure to application security tools/processes (SAST/DAST, secure SDLC, threat modeling).
 * Any familiarity with trust/identity/certificates/PKI (helpful, but not the focus).

## Description

We're looking for a hands-on security engineer who ships code-building automation and integrations that make secure development faster, safer, and easier at scale. You'll work on practical security engineering problems across the SDLC, including AI-enabled security use cases and responsible AI guardrails.

What you'll do

 * Build and maintain security automation (services, scripts, integrations) that reduces manual work and improves reliability.
 * Integrate security into developer workflows (code scanning, CI/CD checks, issue routing, PR-based remediation, reporting).
 * Partner with engineering teams to build security in from the start (practical patterns, tooling, and enablement
 * Contribute to AI security and governance controls (prompt/input safeguards, guardrails, monitoring, safe integration patterns).
 * Help accelerate security outcomes with AI-enabled security use cases (e.g., AI-assisted remediation and security workflow improvements).
