That means engineering the core commerce engine, enabling product teams to launch new products and Gusto to monetize its offering. Support new billing models for Gusto like multi-entity, multi-currency anniversary billing. If you're drawn to work that combines technical craft with real-world impact — helping power the livelihoods of millions using Gusto products — join us!

Here’s what we’re looking for: • Successful applicants typically have 8+ years of software development experience. • Passion for creating scalable, efficient platforms for users. • Experience leveraging AI tools or systems to accelerate development, improve testing, and deliver new platform capabilities. • Curiosity and experimentation with emerging AI frameworks , applying and sharing best practices to evaluate and scale AI use safely across teams • Experience in building large high throughput distributed systems. • Experience in the Commerce domain: invoicing, commerce, payment processing space revenue recognition. • Experience owning multi-quarter projects that solve complex engineering problems and make measurable user impact at scale. • Experience with large scale refactors, performance and reliability issues, and a strong sense of ownership over all aspects of your platform area. • Ability to mentor engineers to maximize their performance and impact.</l
