At NerdWallet, we're building tools and experiences that help people make smarter financial decisions. As a Security Software Engineer focused on AI and Automation, you'll help strengthen the security, reliability, and trust behind those experiences by designing AI-powered security systems that make secure software development more scalable and effective across our engineering organization.
In this role, you'll partner closely with security engineering and infrastructure teams to build automation and AI-powered solutions that help identify vulnerabilities, improve security reviews, and reduce risk across our platforms. You'll take ownership of security engineering initiatives that combine software development, AI systems experience, and security-first thinking to solve meaningful problems at scale.
You'll have room to bring new ideas, influence how AI and automation practices evolve at NerdWallet, and shape the future of security tooling within a team that values curiosity, informed risk-taking, and thoughtful problem-solving.
