Responsibilities
Build and deliver quality software. You will write, test, and deploy code across our AI pipeline using Python and a variety of generative AI and other machine learning tools & techniques. You'll work with large language models, fine-tune prompts, design evaluation metrics, and implement responsible AI practices. You’ll work on team-level projects, applying engineering best practices and contributing to the team’s technical decision-making
Grow as a full-stack developer. You'll have opportunities to build features end-to-end by expanding your skills with Ruby on Rails, React and TypeScript. You'll collaborate with our product engineers to understand our tech stack and how AI capabilities integrate with our web app and APIs
Collaborate with cross-functional partners. Our teams include product managers, designers, and engineers working together to accomplish shared goals. You will collaborate with these partners, beginning with problem discovery through solution design and delivery. We work in two-week cycles and release to production at least once a week
Own your software through its entire lifecycle. In addition to shipping code, you will assess our most pressing product and engineering problems, identify and design solutions, write technical specs, and scope and break down projects. You will also spend approximately one week per quarter on call, serving as the first line of defense against service outages and critical bugs. If you don’t have experience with all of this yet, don’t worry - we’ll teach you!
