Staff Software Engineer, Retirement AI

Gusto is looking for a Staff Software Engineer to join the Retirement AI team. The role involves designing and shipping production features using large language models, working closely with product and design, and iterating quickly. The team is senior and execution-focused.

• 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.

• 7+ years of software engineering experience building and shipping production products or platforms.
• Hands-on experience implementing LLM-powered features (e.g., RAG flows, agents, tool loops, workflow automation with language models, etc).
• Strong engineering skills (e.g., services, APIs, data flows); comfortable spending most of your time coding.
• Experience running or heavily contributing to a team’s execution: sprints, Jira, scoping, and cross-functional coordination.
