About Goodfire

About the role

We’re looking for our first security hire to own security across our infrastructure, product, and company. The security landscape is changing daily as AI gets more capable, and we need to protect ourselves against sophisticated, fast-evolving threats.

This is a foundational, hands-on role. We need a strong engineer who stays on top of new vulnerabilities and attacks, responds quickly when one could affect us, and understands how the threat model is evolving. You’ll help define what security looks like for an AI research lab, working closely with our research, engineering, and operations teams.

Key responsibilities

Incident and vulnerability response: track new exploits, supply chain risks, and third-party breaches as they go public, then assess our exposure and fix it fast.
Access and credentials: limit what people, services, and AI agents can reach, with short-lived credentials and tightly managed API keys.
Monitoring and detection: logging and alerting across our cloud, clusters, network, and SaaS tools.
Product security: keep our product secure as we build and ship new features.
Infrastructure security: secure our cloud, GPU clusters, and agent sandboxes.
Security operations: SSO, MFA, and endpoint security.

What you'll bring

Required experience

5+ years in security engineering, with hands-on ownership of cloud and infrastructure security.
Strong software engineering skills and experience building security tooling.
Experience running incident response and vulnerability management.
Strong grasp of AI security, including how AI agents change the threat model and how to use them in security work.
Willingness and humility to own anything security-related yourself, big or small.

Preferred qualifications

Startup experience or building a security program from scratch.
Experience securing ML research infrastructure or sandboxes for AI agents.
Experience with application and product security.
Corporate security experience: SSO, MFA, and endpoint management.

Take ownership and initiative

There are no bystanders here. We proactively identify problems and take full responsibility over getting a strong result. We are self-driven, own our mistakes, and feel deep responsibility over what we're building.

The expected salary range for this position is $250,000 to $500,000 USD.

This role reports to our CTO.

Most importantly, you'll have the opportunity to join a vital mission at an important point in its trajectory. We are developing groundbreaking technology with a world-class team on the critical path to ensuring a safe and beneficial future for humanity. If you want to do your life's work with us, even if you believe you do not meet every single requirement, apply now.
