Security Engineer

Snyk is the leader in secure AI software development, helping millions of developers develop fast and stay secure as AI transforms how software is built. Our AI-native Developer Security Platform integrates seamlessly into development and security workflows, making it easy to find, fix, and prevent vulnerabilities — from code and dependencies to containers and cloud.

Our mission is to empower every developer to innovate securely in the AI era — boosting productivity while reducing business risk. We’re not your average security company - we build Snyk on One Team, Care Deeply, Customer Centric, and Forward Thinking. It’s how we stay driven, supportive, and always one step ahead as AI reshapes our world.

As a Security Engineer on the Code Rules team (part of Snyk Code), you sit at the intersection of security research, static analysis, and artificial intelligence. Your mission is to transform deep security insights into scalable, automated intelligence.

In Code Rules, we turn vulnerability research into automated detection rules, allowing us to identify a flaw once and scale that protection across every codebase we scan. You will be responsible for building the logic that enables our hybrid SAST and AI engine to recognize complex security patterns across dozens of languages and thousands of frameworks, protecting millions of developers worldwide.

You will be responsible for keeping Snyk at the forefront of the security landscape. This involves researching how new languages and emerging frameworks introduce unique threats and then encoding that knowledge into detection rules that run at scale.

You’ll spend your time:

• Authoring high-precision detection rules using our proprietary logic and domain-specific languages to identify vulnerabilities across various codebases.
• Partnering with Program Analysis experts and software engineers to pioneer new approaches in vulnerability detection, leveraging cross-functional expertise to solve complex security challenges.
• Investigating new technologies to understand how they handle data and security-critical operations.
• Working with customers, understanding their pain points and challenges, and helping secure their code.

What you’ll need:

• A passion for "Security as Code" and the drive to spend time automating a detection rather than fixing a single instance of a bug.
• An interest in diving into the internals of how languages work—from memory management to how specific frameworks handle state.
• Demonstrated experience and knowledge of Application Security Vulnerabilities.
• Proficiency in a programming language.
• Interest in learning about the mechanics and inner workings of a language or a framework, and the ability to self-study highly technical concepts.
• A passion for cybersecurity, and a desire to contribute and be an active participant in the security community.

We'd be lucky if you:

• Have experience in Static Analysis (SAST), compiler design, or formal methods.
• Are familiar with how modern CI/CD pipelines and developer workflows operate.
• Have a track record of contributing to the broader security community or publishing original research.

We care deeply about the warm, inclusive environment we’ve created and we value diversity – we welcome applications from those typically underrepresented in tech. If you like the sound of this role but are not totally sure whether you’re the right person, do apply anyway!

Snyk is committed to creating an inclusive and engaging environment where our employees can thrive as we rally behind our common mission to make the digital world a safer place. From Snyk employee resource groups, to global benefits that help our employees prioritize their health, wellness, financial security, and a work/life blend, we aim to support our employees along their entire journeys here at Snyk.
