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, at a company where AI agents are rewriting how software gets built and security has to keep pace. About the Team: You'll join one of Snyk's Core R&D engineering teams, the group responsible for the shared infrastructure and platform capabilities that power Snyk's products. The team partners closely with product engineering across the company, and reports up through R&D engineering leadership. What You'll Do: * Lead key efforts from idea to execution, demonstrating end to end ownership of complex technical problems. * Analyze, design, and implement high-quality, well-tested solutions to problems with real ambiguity. * Mentor and coach junior engineers, helping grow the next generation of engineering talent at Snyk. * Build systems with a long-term mindset: strong design, robust testing, and scalability from day one. * Collaborate cross-functionally to ensure the infrastructure you build is adopted broadly and used consistently. * Resolve critical bugs and customer support escalations to protect a high-quality user experience.
