As a Senior Software Engineer, you’ll be at the forefront of how we apply Artificial Intelligence to software engineering—building the foundational frameworks, experimenting in real production workflows, and contributing to how teams across the company build with AI. We are looking for an experienced Full Stack Engineer with a deep passion for using AI and automation to solve complex, large-scale problems. Hot Start & High Impact: You won't be on a "listening tour." Your first 90 days will involve tackling tangible projects that provide an immediate impact on engineering productivity. Shape the Future: You will be at the forefront of applying generative AI and ML to drive meaningful improvements to how our engineering teams work. Ownership and Ambition: You will have significant ownership over the tools and platforms you build, solving complex, open-ended problems that directly contribute to our company's ambition and growth.

Requirements

5+ years of full stack development experience.
Hands-on experience with one or more front end technologies (React, TypeScript, Angular, Vue, etc.)
Strong experience with specific AI/ML frameworks or platforms (e.g., PyTorch, TensorFlow, LangChain, Claude, Gemini, Copilot).
Prior experience in a high-growth environment, navigating technical complexity and change.
Experience with Python / Django or similarly typed languages.
Experience with designing and managing scalable databases.
Experience building and maintaining complex software. You’ll join us in writing clean, maintainable software that solves hard problems. You’ll write testable, quality code. You’ll push the team and the mission forward with your contributions.
