About the Team:

We’re hiring Senior Staff AI Software Engineers to build the future of the small business back office, powered by AI agents. Our team’s mission is to create AI-driven solutions that make small business owners 10x more efficient. This team operates like a startup within Gusto, where you’ll report directly to Gusto’s co-founder/Head of Technology.

We welcome experienced Senior Staff Full Stack Engineers who are passionate about AI and excited to dive into this space. While prior AI experience is a plus, it is not a hard requirement. If you have a strong software engineering background and a desire to work on cutting-edge AI applications, we’d love to hear from you.

Here’s what you’ll do day-to-day:

Design, develop, and deploy AI-powered applications to enhance small business operations.
Collaborate closely with Gusto’s co-founder and a high-impact team to build and ship production-quality code.
Contribute to architectural decisions and best practices for AI-driven systems.
Stay on top of industry trends in AI and machine learning, integrating relevant advancements into our solutions.
Mentor and provide guidance to engineers, helping them grow their expertise in AI and software development.

Here’s what we’re looking for:

12+ years of software development experience, with a strong background in Full Stack or Backend development.
Proficiency in modern programming languages and frameworks (e.g., Python, Ruby, TypeScript, React, etc.).
Experience building scalable, high-performance distributed systems.
Strong problem-solving skills and the ability to navigate ambiguity in a fast-paced environment.
Passion for AI-driven technologies. Experience with AI, machine learning, or LLMs is highly preferred.
A startup/founder mindset – comfortable with ambiguity, risk-taking, and operating in a high-intensity environment.

If you’re a talented engineer eager to shape the future of AI-powered business solutions, we encourage you to apply!
