Job Description

Protagonist is seeking a Senior Full Stack Engineer (AI Platform) to help build and evolve our internal AI-powered platform. This role is designed for an experienced engineer who can own production systems end-to-end—from backend services and data infrastructure to intuitive, analyst-facing applications—and who is excited to apply modern AI capabilities within a robust software platform.

The ideal candidate is a strong full-stack engineer first, with experience building AI- and LLM-powered applications in production. You are comfortable working across the stack, making pragmatic architecture decisions, and taking ownership from technical design through deployment. You thrive in a fast-paced, small-team environment, are comfortable navigating ambiguity and complex technical problems, and bring the judgment and experience to help raise the bar for the engineers around you.

Reporting to the VP of Technology, you will design and build core applications and services that power our platform, partnering directly with technical leadership to shape product and architectural direction. You will also collaborate with our customer-facing team to translate analyst and customer needs into scalable, reliable software.
