Who You Are   This isn't just another engineering role. You'll be joining what's essentially a startup within Bishop Fox – all the innovation and rapid iteration of an early-stage venture, powered by the resources and reputation of an established security leader.    You are an experienced AI engineer who thrives on building real systems that operate in messy, unpredictable environments. You care deeply about reliability, evaluation, and scale—not just whether something works once, but whether it works consistently in production.   Your mission? Build autonomous AI agents that identify genuine vulnerabilities in production applications, capable of thinking, adapting, and hacking like the world's top penetration testers.    What You Will Do   Pioneer AI-Driven Security Testing    Design and build intelligent autonomous security testing agents using large language models and cutting-edge AI/ML techniques    Create systems that can autonomously perform reconnaissance, identify vulnerabilities, and execute sophisticated attack chains   Push the boundaries of what's possible when artificial intelligence meets offensive security    Build robust planning, tool-use, and failure-handling mechanisms for agents operating in real-world, unpredictable applications   Revolutionize Pen testing at Scale    Develop services that think and act like elite attackers, but operate 24/7 across thousands of targets    Transform manual testing processes into intelligent, scalable automation pipelines    Build systems that continuously evolve and improve their attack strategies    Implement long-running agent memory and context management so agents retain state, avoid redundant actions, and accumulate application knowledge   Integrate with Enterprise-Grade Infrastructure    Connect your AI agents into Bishop Fox's Cosmos cloud platform    Scale your creations to serve Fortune 100 clients with enterprise-level reliability    Design architectures that can handle massive concurrent testing operations    Develop browser and application interaction infrastructure that enables agents to navigate, interact with, and test modern web applications   Experiment & Innovate Rapidly    Prototype breakthrough approaches to AI-driven security testing    Build sophisticated feedback loops that make your agents smarter over time    Implement safety mechanisms and ethical guardrails for responsible AI deployment    Measure, iterate, and continuously enhance agent performance    Design evaluation and monitoring systems that distinguish real vulnerabilities from false positives or hallucinated findings   Collaborate with Elite Security Minds    Work directly with world-class penetration testers and security researchers   Partner with data scientists and AI specialists to solve novel technical challenges    Contribute to a team culture where hacking expertise meets cutting-edge artificial intelligence    Apply real-world production feedback from customer environments to refine agent behavior and system reliability   Your Experience     7+ years of software engineering experience with a track record of shipping production systems   Deep AI/ML expertise – hands-on experience with LLMs, agent frameworks (LangChain, AutoGPT, CrewAI), or autonomous AI systems    Advanced programming skills in Python and Golang with clean, scalable code practices    Full-stack capabilities – comfortable building robust APIs, designing database schemas, and working with modern frontend frameworks (React/TypeScript experience valued)    Practical experience designing, evaluating, and improving agent reliability, including handling failures, edge cases, and non-deterministic behavior   Experience with cloud platforms (AWS, GCP, or Azure) and containerization (Docker/Kubernetes)    Understanding of CI/CD pipelines and DevOps practices for reliable deployments    Ability to architect systems that can scale from prototype to enterprise-grade solutions    Must be based in the San Francisco Bay Area; remote-first with occasional, ad hoc in-office meetings only when necessary.   The Right Mindset    Portfolio over pedigree – we care more about what you've built than where you learned it    Excitement about autonomous systems and AI agents that can operate independently    Comfort with ambiguity and rapid iteration in a fast-moving environment    Strong judgment in choosing the right tools, models, and architectural approaches for real-world constraints   Bonus Multipliers     Experience in penetration testing, red teaming, ethical hacking, or security research    Understanding of common vulnerabilities, attack vectors, and security frameworks    Knowledge of security tools and methodologies (but we'll teach you what you don't know!)    Open-source contributions, especially in AI/automation or security domains    Hackathon victories or compelling side projects that demonstrate your creativity    Experience in startup environments or greenfield product development    Publications, talks, or thought leadership in AI or security communities    Familiarity with multi-agent systems, reinforcement learning, or swarm intelligence    Experience with vector databases, RAG pipelines, or advanced prompt engineering    Understanding of AI safety, alignment, and responsible AI development practices    Our Values     We strive to live by our values every day, in support of our core tenets, which are to deliver the highest quality of work for our clients, quality of life for our team, and quality of business for our industry and our future.    Be Excellent to Each Other   Do the Right Thing    Do What You’ll Say You’ll Do    Get Better Together    Give a Sh*t    We offer a variety of benefits and perks, such as:     Generous Time Off and Company-Wide Holidays    Health Insurance options including Medical, Dental, Vision    Retirement;
