About The Position

We’re looking for a Staff Security Engineer to lead the security of the cloud applications and AI systems we build and ship for clients. This role is ideal for an experienced engineer who can define security architecture and standards, own the hardest security problems end-to-end, and provide technical leadership across teams. In this role, you will work as a key technical leader on a cross-functional team, defining security architecture across cloud infrastructure, application code, and AI/LLM workloads. You’ll lead threat modeling and security reviews, mentor more junior engineers, partner closely with engineering and leadership, and ensure the systems we ship are secure, reliable, and built to last.

Requirements

7+ years of professional security or software engineering experience, with at least 3 years leading application and cloud security initiatives
Deep expertise in application security, secure coding practices, and the OWASP Top 10
Strong experience with threat modeling, penetration testing, vulnerability management, and secure code review
Deep cloud security expertise across identity, network, and data layers
Strong experience embedding security automation and policy-as-code into CI/CD pipelines
Strong experience with detection engineering, logging, and incident response at scale
Strong experience securing AI and LLM-powered applications, including prompt injection, data leakage, model abuse, and agentic-AI threats
Experience with security, compliance, and governance frameworks
Demonstrated leadership and technical mentoring experience across a team or organization
Strong stakeholder communication skills, with the ability to translate technical depth across audiences
Demonstrable, day-to-day usage and expert knowledge of AI-forward tools such as Claude and Cursor
Excellent problem-solving skills and the ability to navigate highly ambiguous technical and business challenges with sound judgment

Nice To Haves

A doer. You see something broken and fix it. You'd rather move on clarity than wait for certainty.
A fast learner who knows you don't know everything. The AI landscape changes weekly. You're senior enough to know better and curious enough to keep learning anyway.
Direct in a way that makes the work better. You give honest feedback. You'd rather have the hard conversation than blow smoke.
Obsessed with craft. You know genius is in the details. You ship exceptional, not perfect, and you don't put your name on work you wouldn't stand behind.
Built for ownership. You honor commitments, admit mistakes fast, and back your teammates when a decision costs something. No handoffs, no finger-pointing.
All in. You treat clients' businesses like your own. You take the work seriously without taking yourself seriously.
Resourceful when the budget, timeline, or team is tight. Constraints don't slow you down. They sharpen you.
Glad to be in the room with people who care as much as you do. Our teams average fifteen-plus years of experience. We hire people who push each other to do better work.
