What you will do

• Architect and implement production-grade multi-step AI agents to automate end-to-end creator discovery, negotiation, and campaign management.
• Build and scale robust backend systems using Python and FastAPI, focusing on LLM orchestration and efficient agentic workflows.
• Collaborate directly with founders to shape the product's technical direction and translate creator marketing challenges into autonomous AI solutions.

The ideal candidate

• 3–8 years of professional software engineering experience, specifically at Series A–D AI-native startups or high-growth tech environments.
• Proven track record of shipping AI agents or LLM-powered systems in production environments using Python and modern agent frameworks.
• Pragmatic builder mindset with the ability to own entire features from architecture to deployment in a fast-paced, high-stakes San Francisco office environment.

We never post fake jobs This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
