This person role will contribute heavily to the backend of an AI-powered research tool. Successful candidates will possess strong backend engineering skills, as well as a deep knowledge of LLMs and Agentic systems. The right candidate has a strong mental model of the Generative AI space — they can speak to the technical specifications of different models and frameworks, design multi-step agent workflows, and make informed decisions about when and how to deploy LLM capabilities beyond using them as a coding assistant.

Exposure to data engineering or data-adjacent work at scale is a strong indicator of success, though not a requirement.

This role carries long-term growth potential. As the project matures, the right candidate will have the opportunity to step into a lead position, taking on greater ownership of architecture decisions and team direction.

This is a highly client-facing role and ideal for an experienced engineer who enjoys working with non technical stakeholders. This is a
