Staff Software Engineer (Retirement AI)

• You’ll be a key engineer helping us ship real, user-facing AI at Gusto Retirement. 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.
• 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
• 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

• Strong engineering skills (e.g., services, APIs, data flows); comfortable spending most of your time coding
