About the role

As a full stack engineer on Semgrep’s Supply Chain team, you’ll build customer-facing features to help developers secure their software from vulnerabilities introduced by third-party dependencies. Other supply chain management tools exist, but they produce far too much noise to be useful or efficient. Security and engineering teams may receive thousands of critical vulnerabilities that need updating, when in reality they are not even using those dependencies in a vulnerable way. Perhaps you’ve even felt this pain yourself!

Our goal is to cut through the noise: to make it easy to find and remediate the 2% of vulnerabilities that are actually reachable given the way our customers’ use their dependencies. We work to make supply chain security as simple and intuitive so developers can focus on their own mission.

Semgrep Supply Chain has strong product-market fit, and is loved by tiny startups to large enterprises. We need your help to meet the needs of our growing customer base.

You will:

• Build a product that makes the world safer by making developers’ lives easier

• Work on major product initiatives end-to-end, from user-research through design, implementation, and deployment

• Help set technical and product direction, collaborating with the team to determine the future of the product, what features to build, and how to build them

• Build scalable systems that meet the demands of tomorrow’s customers

• Advise and mentor other engineers via thoughtful code reviews, planning discussions, technical documentation, and formal mentorship

You are ideal for this role if you have:

• 5+ years of experience writing production software, building web applications, and operating with high autonomy. Our stack includes Python, Typescript, Postgres, and DGraph

• Excitement about building a product for developers in a highly iterative environment

• Enjoy helping startups mature their product to meet new demands in scale and performance

• Excellent and proactive communication, both verbal and written

Some examples projects you might work on include:

• Tastefully using AI to help customers prioritize and remediate security vulnerabilities

• Features to help customers respond to the next dependency malware incident (e.g. sha1-hulud, tj-actions)

• Allow customers across a wide variety of languages and package managers to have a seamless onboarding experience

• Collect and expose health metrics on open source dependencies to help keep users’ software free of poorly maintained, low quality, and malicious packages

• Build data flow and call graphs to determine whether vulnerabilities from transitive dependencies are reachable from users’ code

This position is preferred to go into an office 2-3 days/week.
