About Semgrep
Semgrep is on a mission to make it expensive to exploit software. As the team behind the most popular SAST, we built the Semgrep AppSec Platform to deliver industry-leading code, dependency, and secrets scanning to enable organizations to ship secure code quickly without slowing down development. With fast, customizable code analysis across large codebases, Semgrep helps teams catch vulnerabilities early and fix them faster. Leading companies like Snowflake, Plaid, Figma, Lyft, and Dropbox rely on Semgrep to secure their software.Semgrep is funded by top investors, including Felicis Ventures, Lightspeed Venture Partners, Menlo Ventures, Redpoint Ventures, and Sequoia Capital.
About the role
As a software engineering intern at Semgrep, you’ll work with our developers, security engineers, and academic research partners to create a tool that empowers people to activate the standards that they care about for their code.Along the way, you’ll learn how people write secure code that lasts, best practices in coding, and functional programming (yayyy!), as you meet developers and security professionals at organizations ranging from early-stage startups to social-media giants, and as you work with program analysis experts who are passionate about making developers’ lives easier.As a member of our team, you’ll be treated with respect and high standards, just like anyone else here.
You'll be a part of the decisions that make an early-stage startup successful and your work will be critical to our mission. Every feature you build will have a measurable impact on our users’ lives.
