About The Position
Higgsfield AI is seeking a hands-on Member of Technical Staff, Product Security to identify and eliminate security vulnerabilities across its AI products and platforms. The role focuses on securing agentic systems, code-generating agents, generative AI models, and enterprise applications, working closely with Product and Engineering to find architectural weaknesses, address vulnerabilities at their root cause, and turn recurring issues into scalable security standards and automated controls. This role combines offensive security testing, secure design and application security, security engineering and automation, and technical ownership. The position is hybrid in the San Francisco Bay Area, with three full days per week in the San Francisco office and the remaining days worked remotely. Employees are expected to be available during agreed working hours and maintain sufficient overlap with the relevant team’s time zone.
Requirements
- At least 5 years of hands-on experience in product security, application security, penetration testing, or vulnerability research.
- A proven track record of independently discovering and exploiting real vulnerabilities through application security work, bug bounty programs, or security research.
- Deep understanding of web application and API security, including authentication, authorization, and multi-tenant isolation.
- Ability to read and analyze modern codebases, identify root causes, and collaborate with engineers on remediation.
- Experience conducting threat modeling, secure design reviews, and hands-on penetration testing.
- Proficiency in scripting or programming languages such as Python, JavaScript, TypeScript, or Go.
- Familiarity with cloud infrastructure, containers, and modern application architectures.
- Ability to translate security findings into scalable engineering controls and automated checks.
- Strong technical judgment, independent problem-solving skills, and a proactive approach to identifying security risks.
Responsibilities
- Conduct hands-on penetration testing of new products and features, including web applications, APIs, and administrative interfaces.
- Identify security risks across agentic systems, MCP servers, code-generating agents, and AI-powered applications.

- Develop proof-of-concept exploits, validate findings, and retest remediation efforts.
- Partner with Engineering early in product development to identify and prevent security flaws before release.
- Conduct threat modeling, architecture reviews, and security-focused code reviews.
- Analyze codebases to trace vulnerabilities to their root cause and recommend effective fixes.
- Assess security risks across generative AI products, user-deployed applications, and enterprise features such as SSO and role-based access controls.
- Translate recurring vulnerabilities into secure development standards, reusable controls, and automated security checks.
- Build security tooling and integrate preventive controls into development and CI/CD workflows.
- Identify systemic weaknesses and implement solutions that prevent entire classes of vulnerabilities.
- Apply cloud, container, and infrastructure security knowledge to investigate vulnerabilities across the application stack.
- Own security findings from discovery through remediation, working directly with engineers to implement lasting fixes.
- Prioritize vulnerabilities based on exploitability, business impact, and real-world risk.
- Establish practical security standards that enable rapid product development without compromising security.
- Help define security practices for emerging AI technologies and new product architectures.
