Software Engineer, Security

Gamma • San Francisco, CA

19h • $180,000 - $310,000 • Onsite

About The Position

You'll protect Gamma's platform, infrastructure, and data as we scale to serve hundreds of millions of users. That means building security tooling and automation, partnering with engineering teams to embed security into everything we ship, and helping shape how the company thinks about security as a practice. You'll work across the organization to identify and mitigate risks without slowing down development velocity. This role combines hands-on security engineering with strategic influence. You'll write code to solve security problems, conduct architecture reviews, lead vulnerability management, and drive initiatives for compliance frameworks like SOC 2 and ISO 27001. You'll work closely with engineering, product, and compliance to make security foundational rather than reactive. Our team has a strong in-office culture and works in person 4–5 days per week in San Francisco. We love working together to stay creative and connected, with flexibility to work from home when focus matters most.

Requirements

• 5+ years of software engineering experience with at least 2–3 years focused on security engineering or application security

• Proficiency in at least one backend language (Python, TypeScript/Node.js, or Go preferred) with experience building security tools
• Deep understanding of web application security including OWASP Top 10, common vulnerability classes, and authentication/authorization patterns, with experience implementing security controls in CI/CD pipelines and infrastructure-as-code (Terraform, CloudFormation)
• Clear communicator who works well embedded with product engineering teams
• Background in penetration testing, offensive security, and SIEM/log analysis
