Higgsfield AI is seeking a hands-on Member of Technical Staff, Product Security to identify and eliminate security vulnerabilities across rapidly evolving AI products and platforms. The company is the fastest-scaling generative AI company in history, hitting $1B in annual revenue run rate with 30M+ users worldwide and powering 390 Fortune 500 brands.
In this role, you will conduct offensive security testing, identify architectural weaknesses, and drive fixes to their root cause. Working closely with Product and Engineering teams, you'll play a critical role in securing new features before they reach production, including agentic systems, code-generating agents, and enterprise applications.
Key responsibilities include:
- 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
- Map attack surfaces and uncover authorization, authentication, and multi-tenant isolation vulnerabilities
- 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 complex codebases to trace vulnerabilities to 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
- 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
This is a hybrid role based in the San Francisco Bay Area. Team members are expected to work from the San Francisco office three full days per week, with remaining days worked remotely.
REQUIREMENTS:
- 5+ years of hands-on experience in product security, application security, penetration testing, or vulnerability research
- 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
- Strong 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 proactive approach to identifying security risks
