Senior Staff Software Engineer at Gusto

This role is designed for a heavyweight engineer with over 10 years of experience, specifically someone who thrives on deep architectural "puzzles" rather than just building surface-level features. You should be a Ruby on Rails expert who has a track record of leading complex platform-level projects, such as service extractions or building reusable component libraries that other engineering teams rely on. The compensation package is high-end, ranging from $189k up to $279k depending on your location, plus additional stock equity. While the role follows a hybrid "office-centric" model (2-3 days on-site), it offers the chance to work at a Staff level where you can influence the technical direction of the entire Benefits organization. You'll also get to integrate modern AI tools into established fintech environments. **You might be a good fit if you:** * Have 10+ years of experience and a "Builder" mindset for large-scale systems. * Are an expert in Ruby on Rails and complex data modeling. * Enjoy mentoring senior engineers and driving technical health across multiple teams. * Want to solve ambiguous scaling challenges within the small business economy.
