Retirement AI Senior Staff Engineer at Gusto

**Who this is for** This role is designed for a heavyweight engineer with over a decade of experience who still loves to code. It is ideal for someone who has pivoted into the AI space and understands how to move beyond "hello world" prompts into building production-grade LLM features involving RAG, agents, and workflow automation. You should be comfortable working in a high-seniority, execution-focused environment where you own features from conception to deployment. **Key highlights** The compensation is highly competitive, starting at $191k and scaling up to $279k depending on location, with stock equity provided on top. The role offers a hybrid work model (2-3 days in-office) in major hubs like Denver, San Francisco, or New York. This is a high-impact position within the Retirement division, offering the stability of an established company with the fast-paced, iterative culture of a small AI product team. **You might be a good fit if you...** * Have 10+ years of experience and a "bias to action" when it comes to shipping code. * Are experienced with Ruby on Rails and React (or similar modern stacks). * Have a proven track record of implementing LLM-powered features like tool loops and RAG flows. * Enjoy collaborating closely with product and design partners to de-risk technical architecture.
