Senior Full-Stack Software Engineer, Applied AI

The Applied AI team at Circle is at the forefront of leveraging AI to drive innovation for our customers through transformative applications of large language models (LLMs). We're looking for a strong full-stack engineer who is proficient in web frameworks, backend development, and infrastructure to spearhead the development of full-stack AI solutions across Circle.

You will work on exciting projects such as AI agents, Retrieval-Augmented Generation, internal tooling for customer-facing teams, fine-tuning models, and building infrastructure for LLM inference. While AI experience is valuable, what we care about most is a strong experimentation mindset. If you’re excited about rapidly testing ideas, running A/B experiments, and iterating on real production use cases of LLMs, this role is for you.
