Software Engineer, Security

Job summary

Responsibilities

We’re looking for a software engineer focused on making our products secure by default while supporting fast and ambitious product iteration. You’ll embed with product and research teams to bake security into design and development and to build tooling and automation that keep systems safe at scale.

• Partner with product and research teams to embed security into the development lifecycle: threat modeling, design reviews, and secure defaults for new features.
• Design and implement security controls across our product stack (authentication, authorization, session management, input validation, etc.).
• Build and maintain security tooling and automation for engineers: secure frameworks and templates, CI/CD checks, dependency management, and vulnerability detection.
• Collaborate with researchers to identify and mitigate AI-specific product risks, such as model abuse, prompt injection, data leakage, or misuse of capabilities.
• Improve observability and detection for security-relevant events: access anomalies, abuse patterns, and suspicious behavior in production.

What they're looking for

• Bachelor’s degree or equivalent experience in computer science, engineering, or similar.
• Proficiency in at least one backend language (we use Python or Rust).
• Strong generalist software engineering background and ability to review production code for security risks.
• Hands-on experience securing web apps and APIs especially auth flows, access control, secrets management, input validation, and data protection.
• Familiarity with common vulnerability classes and prevention frameworks; experience hardening prototypes into production.
