Our mission is to make world-class software security available to everyone. This means building program analysis tools that are open source, easy to use, powerful, and fast. It also means building a team with security expertise and a passion for great developer experiences. Most of all, it means working with honesty and respect in a diverse community of dreamers and builders. We’ve redefined static analysis tooling by committing to all of these, and turned our project, Semgrep, into an essential safeguard for code at Snowflake, Dropbox, and more.

As a software engineering intern at Semgrep, you’ll help us build a new category of developer-focused security tools to prevent bugs and security vulnerabilities. You will be joining the team behind the widely used Semgrep. You will get to ship features that make it easier for teams to integrate Semgrep into their existing workflows or build improvements that help our services scale and remain reliable.

Along the way, you will work with a dedicated group of full-stack developers, security researchers, program analysis experts, and infrastructure engineers. You will learn from senior developers who bring experience and wisdom from Google, Facebook, and successful startups. You will work with our clients’ security teams at companies ranging from early-stage startups to social-media giants. You will have opportunities to learn about their individual security philosophies and develop ways to make their lives easier. You’ll attend lunch and learn sessions across the company - learning about everything from advanced type systems to product paradigms. As a member of our engineering team, you will get to speak directly with real customers who are using the features you build – something that makes interning at an early-stage startup so unique! We’re excited to go on this journey with you!

Our goal is to competitively and fairly compensate every Semgrep employee with a system that equally rewards those who are vocal and those who are less comfortable making demands during the final steps of the hiring process. To that end, we generate internal compensation bands that are used when discussing and negotiating salaries. We update these based on market data to make sure they’re above the average for comparable roles.

We also invest in our employees’ well-being and long term success with comprehensive health plans, generous vacation time, 401k, learning stipends, and more. Our benefits are for everyone, so that you’re taken care of, and we work with individuals to make sure they have what they need, whether that’s quiet work space, adjusted hours, or something else.

We have people from France and the Philippines, physics and philosophy, formal methods research and full fledged corporations. We’re new parents and new grads, aspiring authors and aspiring Americans, dog lovers and dogfooders. We get together often to bike, bake, and meet up in parks. In our interactions, we believe respect and honesty go hand in hand, and prioritize both.

Semgrep is an equal-opportunity employer seeking a diverse range of backgrounds. We value who you are — including your cultural heritage, your socioeconomic status, your age, your race, your gender, your sexual orientation, your disabilities. We value what’s vitally important to you — your family, your religion, your politics. We value what you love in this world — your music, your weekend pursuits. We believe in welcoming varied professional backgrounds, educations, and interests. If you’re exceptional in your role, believe in Semgrep’s mission, and treat Semgrep’s values as your own, you belong here.
