This role is all about bias to action: owning problems end-to-end, getting working software in front of customers, and iterating quickly. You'll work closely with a small, senior team to implement language-model-powered experiences. If you like being hands-on, making pragmatic technical decisions, working closely with product & design partners, and turning ideas into production features, you'll be a great fit. About the Team: We're a small, focused AI product team building practical, high-impact experiences to help people save for retirement at Gusto Retirement. The team is senior, collaborative, and very execution-focused-PMs bring strong ideas, and we own the execution fully. We work closely with product, design, and partner engineering teams, but keep tight ownership of our priorities and roadmap. Here's what you'll do day-to-day: * Design, build, and ship production features that use large language models to solve real customer problems. * Implement and integrate LLMs (prompting, tool loops, evaluation, monitoring, etc). * Make pragmatic architecture decisions, de-risk tricky areas, and keep the work unblocked. * Partner with product and design to refine ideas, shape scope, and iterate quickly on end-to-end experiences. * Collaborate with other engineering teams to integrate with existing systems and unblock dependencies. * Write clear, reliable, well-tested code that ships quickly and scales well.
