Build the Offensive AI Security Practice: Stand up and scale a dedicated offensive capability targeting AI/ML systems.
Develop AI Threat Intelligence: Track and operationalize the rapidly evolving AI threat landscape — OWASP LLM Top 10, MITRE ATLAS, emerging attack research on agentic systems — translating external research into internal red team playbooks and detection hypotheses for Security Operations.
Lead structured adversarial campaigns against Postman's LLM deployments, AI agents, and model pipelines — targeting prompt injection, tool-use abuse, data exfiltration via context manipulation, training data poisoning, model manipulation, and trust boundary violations in multi-agent architectures. •
Architect Autonomous Testing: Design and deploy AI-based penetration testing platforms and autonomous agents to perform continuous security validation across our API ecosystem. •
Lead & Cultivate: Build, manage, and scale a high-performing team of offensive security engineers — including specialized AI red team operators — providing mentorship, career development, and succession planning. •
Build a pipeline that includes internal development paths for existing security engineers to cross-skill into AI red teaming.
Drive Security Culture through "The Show": Lead live "Exploitable Demonstrations" — technical proof-of-concepts presented to engineering teams that show exactly how a vulnerability could be leveraged, turning abstract risks into tangible learning moments.
Requirements
We hold active SOC 2 Type II, ISO 27001, ISO 42001, and HIPAA compliance postures, and we are pursuing FedRAMP High and CMMC Level 2 authorization.
Our security stack includes Wiz, SentinelOne, Okta, Jamf, and 1Password, and we operate across a multi-cloud environment.
We focus on continuous security validation, AI-augmented adversary emulation, and offensive AI security research at Postman's scale. The Opportunity
You will own the strategic direction of Postman's offensive security program — including building out a dedicated Offensive AI Security capability from the ground up — and operate as a key partner to CISO leadership on threat-informed defense strategy.
You will shape what offensive security looks like at Postman for the next three years, with a specific mandate to make us an industry leader in adversarial testing of AI systems, agentic workflows, and LLM integrations.
This includes adversarial testing of LLM integrations, agentic workflows (MCP, tool-use chains), RAG pipelines, and model-serving infrastructure.
Red Team AI Systems at Depth: Go beyond checkbox assessments.
Continuous Validation: Move from manual pentesting to Continuous Offensive Security, integrating automated breach and attack simulation (BAS) into CI/CD pipelines, including AI model deployment pipelines. People Leadership •
Recruit for the Future: Identify and hire talent at the intersection of offensive security and AI/ML — a rare and competitive talent market.
Place particular emphasis on demystifying AI-specific attack vectors for non-ML engineers. •
Partner with GRC on audit evidence and compliance posture derived from offensive operations, including AI-specific risk frameworks (ISO 42001). •
Cross-Functional Partnership: Operate as a senior technical leader across Product Security, Security Operations, and Engineering, ensuring offensive findings — especially from AI red team engagements — drive measurable improvements in detection, response, and architecture. About You •
experience managing managers or tech leads. •
AI/ML Offensive Depth: Demonstrated
experience attacking AI/ML systems — whether through adversarial ML research, LLM red teaming, agentic system exploitation, or building offensive tooling for AI targets.
Strategic Acumen: Demonstrated ability to build and scale an offensive security program from the ground up or significantly mature an existing one.
Adversarial Mindset: Deep understanding of the modern threat landscape and how to apply it to cloud-native, API-first environments — extended to AI-native architectures. •
AI Offensive Tooling Fluency: Hands-on
experience with AI-augmented pentesting tools (e.g., PentestGPT, Horizon3, custom LLM-based fuzzing) and purpose-built AI red team frameworks (e.g., Microsoft PyRIT, Garak, custom harnesses).
Understanding of how to manage non-deterministic AI outputs in both offensive tooling and target systems. •
Pragmatic Storytelling: You believe that a well-executed exploit demo is more effective than a 50-page PDF.
You can present a complex exploit chain — including an AI-specific attack path — to a room of developers in a way that is inspiring, not condescending. •
You can architect evaluation harnesses and adversarial test suites for ML models. Preferred •
Industry Presence: Track record of contributions to the offensive security or AI security community — conference talks (DEF CON, Black Hat, BSides, RSA), tool releases, published research, CVEs, or active participation in OWASP, MITRE, or similar working groups. •
Certifications: OSCP, OSCE, OSEP, GXPN, GPEN, CRTP, or equivalent hands-on offensive certifications. AI/ML-specific credentials (e.g., GIAC GMAI) are a differentiator. •
Cloud Security Expertise: Deep familiarity with AWS security primitives, cloud-native attack paths, and container/Kubernetes exploitation. •
API Security Depth: Experience with API-specific attack methodologies — BOLA, BFLA, mass assignment, GraphQL abuse, gRPC exploitation — reflecting Postman's core product domain. •
Compliance Awareness: Familiarity with how offensive security outputs map to SOC 2 Type II, ISO 27001, ISO 42001, FedRAMP, or CMMC control evidence.

Additional details
Postman is helping developers and professionals across the globe build the API-first world by simplifying each step of the API lifecycle and streamlining collaboration—enabling users to create better APIs, faster.
The company is headquartered in San Francisco and has offices in Boston, New York, Austin, Tokyo, London, and Bangalore - where Postman was founded.
The Information Security organization at Postman operates across three pillars: Governance Risk & Compliance (GRC), Product Security, and Security Operations.
The Offensive Security team is the "red" pulse of this organization.
We don't just find bugs — we simulate the adversary to ensure our defenses hold up under real-world pressure.
This is not a role where you inherit a mature program and keep the lights on.
You will lead a team that doesn't just "report" vulnerabilities but "demonstrates" them, using live exploits to build a deep, visceral security culture across the entire engineering organization.
Set Strategic Direction: Define and execute the multi-year offensive security roadmap, aligning Red Team, Purple Team, and continuous validation capabilities to Postman's evolving threat landscape and business priorities. •
You will define the methodology, tooling, and engagement frameworks from the ground up. •
Executive Communication: Translate offensive findings into business-level risk narratives for executive leadership, the board, and external stakeholders.
