Founding Software Engineer | Agentic AI | AI Engineer | Founding Engineer$180k-$220k + 1–2% equityWant to join an AI startup early enough that “founding engineer” actually means something?We're working with an AI startup building multimodal agents that are tackling a pretty huge real-world problem: automating architecture and helping get housing built faster.Their technology uses AI agents to understand architectural blueprints, assess building-code compliance and ultimately automate parts of the architecture process.They’re now looking for a Founding AI Engineer to join the team in San Francisco.This isn't a pure research role. They're looking for someone who combines strong software engineering with applied ML/AI experimentation ; this is ideal for someone who likes building, testing ideas quickly and figuring things out without needing a detailed roadmap.You’ll be working across:Agentic AI and multimodal LLMsPythonComputer visionLLM evals and experimentationSupervised fine-tuning and model distillationRetrieval and context engineeringInternal tooling for faster AI experimentationReal product problems alongside usersWhat they’re looking for:1–6 years across software engineering / ML, ideally with hands-on experience building AI or LLM applications.More importantly, you’ll be highly autonomous, comfortable running your own experiments and able to combine SWE speed with ML rigor. You should also be someone who already uses tools like Claude Code, Cursor or similar as part of your day-to-day development workflow.If you're looking for a role where you can have a massive amount of ownership, work directly on agentic AI and join while the technical foundations are still being built, I'd love to hear from you.Apply directly or drop me a message for more information.Founding Engineer | Agentic AI | San Francisco | AI Engineer
