Software Engineer - Agent Guardrails

Location: Germany (remote) or Bengaluru, India

BlueRock is hiring one engineer to own our language-runtime sensors — the instrumentation layer that hooks into key packages generating events for our policy engine allowing real-time block decisions. It's the layer that sees what an AI agent is actually doing, as it happens.

What You'll Own

• 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.

What You'll Need

• 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.
