Founding Senior Security Engineer AI Fintech

As a senior individual contributor serving as a founding security lead, you will own and mature application security at a growing AI-focused fintech company. You will work closely with engineering to secure AI agent workflows and help build security practices that support a regulated banking environment.

• Build and improve application security tooling, processes, and secure software development practices that fit into engineers' day-to-day work.

• Partner with engineering to design secure AI agent workflows, protect data privacy, and address AI-specific vulnerabilities.

• Automate detection and vulnerability management to reduce manual security work.

• Lead incident response and turn incidents into lasting security improvements.

• Support compliance and customer trust efforts, including SOC 2, ISO 27001, and bank security requirements.

• Four to eight years of application security experience, including hands-on product security work in a fast-growing environment.

• A technical bachelor's degree and strong software security fundamentals.

• Recent experience with secure code review, threat modeling, penetration testing, or security tooling used by engineering teams.

• An individual contributor who primarily performs hands-on security work, rather than a manager or a specialist focused mainly on IT, GRC, network, cloud-only, or security operations.

• Experience in fintech or regulated B2B software is valuable, as is ownership of SOC 2 or ISO 27001 work.

• Familiarity with Type Script, JavaScript, AWS or GCP, secure SDLC, IAM, cloud security, and AI or LLM security.

Annual salary range: $190,000 to $250,000. Visa sponsorship is available.
