# Software Engineer - Agent Guardrails

- **Company:** BlueRock Security
- **Location:** München, Germany
- **Contract:** Permanent contract
- **Skills:** C++ (Programming Language), Memory Management, Python (Programming Language), Node.Js, Performance Tuning, Memory Leaks, Web Application Frameworks, Large Language Models, Build Management, Virtual Agents
- **Published:** August 13, 2026
- **Apply:** https://www.adzuna.de/details/5838605348

## About the Role

* Production mastery in Node.js and Python: experience with dynamic module loading, monkey-patching, and low-level runtime interception in both ecosystems.
 * Systems & FFI fundamentals: Comfort bridging managed runtimes into compiled binaries (e.g., Rust, C, C++), with fundamental understanding of memory management, thread safety, and dynamic linking.
 * Async execution expertise: Deep understanding of non-blocking control flow (asyncio, Node event loop) to ensure hooks never block host applications.
 * Proven track record of building resilient software on top of fast-evolving third-party SDKs and uncooperative runtimes.
 * A diagnostic mindset built for hunting down race conditions, memory leaks, and silent failures across runtime boundaries.

## Description

* Sensor Architecture: Design and build low-latency runtime instrumentation across Node.js and Python to track AI agent execution paths in real time.
 * Ecosystem Expansion: Pioneer hooks and interceptors for emerging protocols (like MCP), LLM SDKs, web frameworks, and new execution transports.
 * Proactive Adaptation Systems: Engineer automated systems and harness tooling to detect, test, and automatically surface upstream SDK shifts before they impact runtime behavior.
 * Performance Optimization: Enforce strict execution overhead budgets to ensure guardrails never compromise host agent execution speed.
