Infrastructure Engineer, Agent Systems

Hawksbill is committed to leveraging Artificial Intelligence to create a more cybersecure and ethically responsible future. Our mission is rooted in putting people first as we address global cybersecurity challenges. With a focus on innovation, we strive to develop reliable and forward-thinking solutions that prioritize ethical practices and user protection. Join us in shaping the future of technology with purpose and integrity.

• Design and operate sandboxed execution environments that host adversarial code safely and at scale
• Build the orchestration layer for parallel agent rollouts, scheduling, isolation, resource management, retries, checkpointing
• Own the tool/MCP integration surface so new capabilities ship without breaking the loop
• Build eval and replay infrastructure so every run becomes training signal and debugging artifact
• Stand up RL infrastructure (rollout collection, reward computation, async actor‑learner setups) when the model work calls for it

• 4+ years of infrastructure or platform engineering, with experience on systems that run untrusted code, orchestrate distributed workloads, or operate at meaningful scale
• Experience at a company running serious agent or distributed‑systems infrastructure (AI labs, robotics/autonomy, quantitative trading, large‑scale CI or sandbox platforms)
• Deep comfort with sandboxing primitives, containers, lightweight VMs and the failure modes of each
• Experience building systems that orchestrate untrusted or semi‑trusted code execution
• Strong instincts for observability and debugging in async, non‑deterministic systems
• You ship. You don’t over‑engineer. You write the ugly version first and clean it up when the shape is clear.

• Built RL training infrastructure (rollout/training separation, async pipelines, reward modeling)
• Security background: red team experience, CTF history, published CVEs, or prior work on offensive tooling
• Hands‑on with MCP, tool‑use frameworks, or custom agent harnesses
• Strong understanding of Network Security to safeguard systems and prevent potential vulnerabilities.
