Senior AI Software Engineer

AI Engineer

As an AI engineer, you'll apply LLM technologies throughout our stack to enhance Semgrep's security vulnerability detection, prioritization and remediation capabilities. You will work directly with customers to understand their pain points, own the end-to-end implementation of AI-powered solutions and rigorously evaluate the efficacy of different prompts and models through experimentation with real-world data. If you are comfortable working with significant ambiguity, like prototyping and shipping quickly and enjoy getting to work on a little bit of everything throughout the stack - this is the role for you.

Our stack utilizes various LLMs including GPT-4/GPT-5, Codex and Claude, Typescript and React on the Frontend, Python, Flask and SQLAlchemy on the Backend, is deployed via Kubernetes and hosted on AWS. Professional experience with these technologies is preferred but not required provided you are open to learning them quickly!

This is a hybrid role with the expectation you join us 3+ days per week in our San Francisco, New York, Boston or Denver offices depending on team. Remote employment will be considered for exceptional candidates as well.

The estimated starting annual salary range for this position is $163,000 to $246,500 USD. The actual base salary will be determined based on a number of factors, which may include job-related skills, relevant experience, qualifications, location, internal equity, and market data. In addition to base salary, total compensation may include equity, variable compensation, and benefits. We view equity as a meaningful part of our compensation philosophy and a way for employees to share in the long-term value they help create.

Compensation ranges are reviewed regularly and may be adjusted as the role, individual performance, or market conditions evolve.
