# Senior Software Engineer

Unleash AI Innovators, Securely Software is being rewritten in real time. AI agents are starting to write more code than humans do, at a speed no security team has ever had to match, and that single shift is opening up the biggest opportunity our industry has seen in a decade. We're not bracing for it, we're building the company that owns it. Snyk is building the next generation security platform where security isn't a set of tools people operate. It's a team of security agents working alongside your engineers, finding, fixing, and governing risk at the speed software is now built. These agents work alongside both the company build and the agents they adopt. Security stops being a queue of work waiting for people, and becomes a coordinated workforce companies direct and trust. Job Summary: Snyk's Core R&D organization builds the infrastructure, platform, and shared systems that every product team at Snyk depends on. As a Senior Software Engineer, you'll take on complex, ambiguous problems end to end: designing the solution, building it, and owning it in production. This is a role for someone who wants real technical ownership and a direct hand in mentoring the engineers around them
