Your Opportunity: We're looking for a Senior Agentic Security Automation Engineer who thrives on technical challenges, enjoys building things from scratch, and has an insatiable curiosity for how software works, how it breaks, and how it can be analyzed autonomously. In this role, your goal won't be to perform security assessments by hand. You'll design agentic workflows, build automation frameworks, integrate security tooling (including that built by our world renowned research team; the people behind Frida and radare2), develop evaluation systems, and create the infrastructure that enables autonomous analysis of applications of all kinds, be it computer, phone or IoT. Success in this role means helping transform security testing from a human-limited activity into a technology-enabled capability that can analyze more applications, execute more test coverage, identify more meaningful security issues, and continuously improve over time. Your first mission is to make our offensive security team faster and more effective in a repeatable way. Where it goes from there is genuinely open, and that's a big part of the appeal. You'll have a hand in shaping it. What You’ll be Doing: Build Agentic Security Testing Systems - Architect, build, and deploy advanced AI agents capable of autonomous reasoning, decision-making, and security analysis. - Design and implement multi-step agentic workflows that replicate and scale expert security testing methodologies. - Develop systems capable of analyzing applications on desktop software, IoT devices, APIs, and emerging technology platforms, building off the expertise of our best-of-breed mobile security testing. - Create autonomous and human-in-the-loop workflows that balance scale, accuracy, and trust. Design Security Automation Frameworks - Develop reusable tools, skills, prompts, workflows, MCP servers, and agent orchestration infrastructure. - Integrate static and dynamic analysis, reverse engineering and decompilation, network analysis, vulnerability intelligence, and custom security tooling into agent workflows, including the kind of instrumentation that powers Frida-style runtime analysis. - Design systems that allow security expertise to be reused and continuously improved over time. Research & Innovation - Stay current on advancements in agentic AI, offensive security, software assurance, and autonomous systems. - Prototype and evaluate new approaches for increasing the scale and depth of security testing. - Collaborate with security analysts and researchers to convert offensive security methodologies into scalable automation. Who You Are: If you're the kind of person who spends a weekend wiring together a new LangGraph workflow, builds a custom tool because the existing one doesn't quite fit, or finds yourself wondering whether an AI agent could perform a security task faster, better, or at a scale impossible for human teams alone, you'll fit right in. This is a highly autonomous role. We're looking for someone who can identify opportunities, define
