Product Security Engineer

About the Role:

We are looking for a Product Security Engineer to join our security team to drive critical product security initiatives across Vercel’s products and platform. Your core focus will be on threat modeling, open-source software security, secure code review, SDLC tooling, and bug bounty program management. You will support both our internal product engineering teams and customer-facing security programs, ensuring that security is embedded throughout our development lifecycle and that our platform earns the trust of developers and end-users alike.

As a senior member of the team, you will lead cross-organizational security projects and champion a security-first culture within Vercel’s engineering organization. This is a high-impact role with broad scope – your work will not only secure Vercel’s core infrastructure and products (built with Next.js, Node.js, and serverless architecture), but also influence the security of the open-source ecosystems we contribute to.

What You Will Do:

• Threat Modeling & Design Review: Partner with engineering and product teams to perform threat modeling for new and existing features. Identify potential risks early in the design phase and recommend security controls or design changes to mitigate threats. You will ensure security concerns are addressed from the inception of features through deployment.
• Secure Code Review: Conduct secure code reviews and security assessments on products and services built with Next.js, Node.js, and our serverless backend. You’ll uncover code-level vulnerabilities, provide actionable remediation guidance to developers, and establish best practices for secure coding across the engineering team.
• Open Source Security Management: Oversee Vercel’s open-source security efforts. This includes monitoring and coordinating fixes for vulnerabilities in third-party open-source packages we use (as a consumer) and ensuring the security of the open-source projects we maintain and publish (as a contributor/publisher, e.g. Next.js). You will work with maintainers and the community on responsible disclosure and patching of security issues in open-source code.
• SDLC Tooling & Automation: Evaluate, select, and integrate security tools into our Software Development Life Cycle. You will drive the implementation of automated security checks – for example, using GitHub Advanced Security (GHAS) and other static analysis, dependency scanning, and secret detection tools – directly in our CI/CD pipelines.
