The company focuses on protecting applications at a fundamental level, ensuring developers can innovate without the constant threat of exploitation. As part of a mission-driven team, this role sits at the critical intersection of app runtime and security, specifically focusing on the emerging world of AI agents.</p><p><br/></p><p>The successful candidate will contribute to the development of a flagship multi-language runtime security platform. This involves building the infrastructure required for deep-trace observability—hooking into frameworks such as CrewAI, Google ADK, and OpenAI Agents—to monitor and intercept malicious intent in real-time. The work covers end-to-end hardening, securing the entire lifecycle from agent orchestration through to execution.</p><p><br/></p><p><strong>Technical Requirements</strong></p><ul><li><strong>Systems Expertise:</strong> At least 5 years of experience as a systems generalist. You should be comfortable working below the API level, navigating the kernel or runtime environments.</li><li><strong>Language Proficiency:</strong> Deep knowledge of Python or JS/Node.js is essential, particularly regarding monkey patching, import hooking, and dynamic instrumentation.</li><li><strong>AI Frameworks:</strong> Hands-on experience with LangChain, CrewAI, or similar agentic frameworks.</li><li><strong>Observability:</strong> Proficiency with OpenTelemetry, Datadog, or similar tools for managing high-cardinality distributed tracing.</li><li><strong>Workflow Efficiency:</strong> Proven ability to integrate AI-assisted coding tools (such as Claude Code, Cursor, or CoPilot) into a daily workflow to accelerate delivery.</li></ul><p><br/></p><p><strong>Preferred Experience</strong></p><ul><li>Familiarity with protocols like MCP (Model Context Protocol) or A2A.</li><li>A "hacker mindset," including OWASP expertise and a strong understanding of deserialization, SSRF, and privilege escalation.</li><li>Experience with container runtimes (OCI, containerd) or a proficiency in Rust.</li><li>Knowledge of Kubernetes or similar orchestration frameworks.</li></ul><p><br/></p><p><strong>The Company</strong></p><p>The company is a well-funded, early-stage venture founded by experienced security entrepreneurs. In an era where attackers exploit vulnerabilities in hours and dependency trees are rapidly expanding, they provide the tools to shift from reactive CVE chasing to proactive foundation protection. This environment is ideal for engineers who want to build secure, resilient systems that allow the global developer community to focus on creation rather than defense.</p><p><br/></p><p><strong>Interested?
