.Every day, the world gets more digital thanks to tens of millions of developers building the future faster than ever. But with exponential growth comes exponential risk, as outnumbered security teams struggle to secure mountains of code. This is where Snyk (pronounced "sneak") comes in. Snyk is a developer security platform that makes it easy for development teams to find, prioritize, and fix security vulnerabilities in code, dependencies, containers, and cloud infrastructure — and do it all right from the start. Snyk is on a mission to make the world a more secure place by empowering developers to develop fast and stay secure. Joining Snyk means embracing our core values: One Team, Care Deeply, Customer Centric, and Forward Thinking. As a member of our team, you'll have the opportunity to thrive in a dynamic environment where fostering collaboration, leading with empathy, driving business impact, and inspiring trust are at the heart of everything we do. Our Opportunity Snyk, a leader in developer security, has acquired Probely, a modern Dynamic Application Security Testing (DAST) provider based in Portugal, with coverage of API security testing and web applications. In this role, you will develop our scanner, a key component of our scanning engine, improving its vulnerability detection capabilities, while adding other features and improving existing ones. Our scanner works in tandem with our crawler, testing web applications and API in an efficient way without reporting false positives, requiring a strong collaboration between various engineering teams. You'll Spend Your Time: Analyzing requirements, specifications, and technical design documents in preparation for development. Developing the scanner's core functionalities, such as integrating with existing scanning modules, scanning queue management, or authentication. Researching, developing, and improving the scanner vulnerability detection capabilities. Contributing to our firing range by adding new vulnerable applications and endpoints for testing purposes. Working with different teams to discuss and implement technical solutions to fix and identify bugs. Implementing tests for any developed code. Reviewing and testing teammates' code. What You'll Need: At least 5 years of commercial experience as a Software Engineer. Solid programming skills in Java. Strong knowledge of web technologies (HTTP, XHR, authentication mechanisms, etc.). Knowledge of security concepts, especially web application security, is highly valued. Proficiency in Git and code management tools like GitHub, GitLab, or Bitbucket. Ability to lift the performance of a team through coaching and mentoring of more junior engineers. Effective communicator both verbally and in writing. Able to work collaboratively, be curious, and have a growth mindset. We'd be Lucky if You: Experience with Python is highly valued
