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
6+ 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
