Senior AI Product Engineer

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 an AI product engineer on Semgrep's supply chain team, you'll apply cutting-edge AI/ML tools from industry leaders (e.g. OpenAI, Anthropic, Hugging Face, Amazon, Google) to build solutions that deliver compounding value for developers.

Semgrep’s supply chain product team builds customer-facing tools to help developers secure their software from vulnerabilities introduced by dependencies. Other supply chain management tools exist, but they produce far too much noise to be useful or efficient. Security teams may file through thousands of vulnerabilities, informing developers that hundreds of their dependencies have introduced critical vulnerabilities and 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 for our users as possible so developers can focus on their own mission. AI has had a profound effect on Semgrep’s ability to cut through the noise so far, and it will likely unlock more potential in the future.

You'll help shape Semgrep into a world-leading static-analysis project while learning about application security, mentoring junior engineers, collaborating on customer-loved tools, architecting data systems, and helping users understand their security posture. Through Semgrep's culture of transparency, you'll see and influence the decisions that make a startup successful.

You will:

• Integrate AI platform APIs into the product
• Develop prompt chains for LLMs
• Experiment with the latest technology advances and understand how they can be leveraged into the product
• Train and fine-tune the ML models using human and machine-generated data
• Learn from users to understand their needs, build products to help keep them secure, and work with them to help them scale their security programs
• Work on major product initiatives end-to-end, from user-research through design, implementation, and deployment
• Ensure continual, high-availability operation of services using modern site-reliability practices, including participation in an on-call rotation

You are ideal for this role if you have:

• 5+ years of experience writing production software
• Curiosity and a love of new technologies
• Experience hacking with GPT-4, Codex, or other LLMs. Experience with ML algorithms and/or research.
• Experience working in a startup or fast-paced environment, comfortable with discarding prototypes often
• Comfortable with coding in Python
• Interest in prompt engineering and vector databases
• Excitement about building for customers, learning their needs, iterating fast, and seeing your solutions solve their core problems
• Excellent and proactive communication, both verbal and written

Some examples projects you might work on include:

• Identify breaking changes between different package versions according to customers’ usage of a dependency
• Provide actionable remediation guidance for vulnerabilities in third-party dependencies
• Identify which of a user’s dependencies would fix the highest number of downstream vulnerabilities when upgraded
• Collect and expose health metrics on open source dependencies to help keep users’ software free of poorly maintained, low quality, and malicious packages
