Job description

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, 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.

What you'll bring:

• At least 7 years of commercial experience as a Software Engineer.

• Expertise in large-scale software systems design and a solid grounding in fundamental computer science concepts.

• Proficiency in at least one of Snyk's core languages: Go, TypeScript, or Python.

• Experience building highly reliable, scalable systems, whether microservice back-ends, web UIs, or platform automation tools.

• A strong commitment to code quality and to giving and receiving direct feedback.

• Clear, effective communication and comfort working through ambiguity.

• Nice to have: experience on early-stage products and direct customer problem-solving, comfort with a hybrid, in-person team schedule, and a sense of humor about a mission you still take seriously.
