Job description

Security Software Engineer | AI Infrastructure Startup

A rapidly growing, venture-backed AI infrastructure company is seeking a highly technical Security Software Engineer to build and own security from the ground up.

This is a rare opportunity to join a founding-level engineering team working at the intersection of security, infrastructure, and artificial intelligence. The company partners with leading AI organizations to support large-scale data creation, model development, and agentic workflows, requiring innovative approaches to securing highly sensitive systems and data.

What You'll Do

• Design and implement security infrastructure across AWS and GCP environments
• Build automated systems for threat detection, incident response, and security operations
• Secure AI-specific data pipelines, model interaction layers, and training workflows
• Integrate security controls directly into engineering workflows without slowing development velocity
• Contribute to core infrastructure and platform engineering initiatives beyond security
• Establish and execute the company's security roadmap while helping define long-term security strategy

What We're Looking For

• 4–7 years of experience in security engineering, infrastructure engineering, or related fields
• Strong software engineering skills with Python, Go, and/or TypeScript
• Experience securing cloud-native environments in AWS and/or GCP
• A builder's mindset—someone who develops security systems and automation rather than relying solely on commercial tools
• Ability to thrive in a fast-paced startup environment with significant ownership and autonomy

Why This Role?

• Founding-level impact and visibility
• Work on cutting-edge AI infrastructure challenges
• Join a highly technical, talent-dense engineering team
• Significant equity upside and competitive compensation
• Opportunity to define security practices at a company experiencing rapid growth

If you're passionate about building security systems that protect next-generation AI platforms and want to have a direct impact on a company's trajectory, I'd love to connect.
