About Gusto

At Gusto, we're on a mission to grow the small business economy. We handle the hard stuff — payroll, health insurance, 401(k)s, and HR — so owners can focus on their craft and their customers. With teams in Denver, San Francisco, and New York, we support more than 500,000 small businesses nationwide and are building a workplace that reflects the people we serve.

All full-time employees receive competitive base pay, benefits, and equity (RSUs) — because everyone who helps build Gusto should share in its success. Offer amounts are determined by role, level, and location. Learn more about our Total Rewards philosophy.

AI is a fundamental part of how work gets done at Gusto. We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process.

About the Team:

You'll join the Application Engineering team, which supports the platforms we use to deliver exceptional Sales and CX interactions. Our platforms have tremendous scale, and the work we do here directly shapes how the rest of Gusto operates. We challenge the status quo, advocate for scalable technical solutions, and hold a high bar for what "great" looks like - while staying grounded in translating ambiguous requirements into real business value.

 

Here’s what you’ll do day-to-day:

  • Design, build, and maintain scalable Apex solutions on the Salesforce platform that support our Sales and CX teams
  • Use AI coding assistants (e.g., Claude Code or equivalent) throughout the development lifecycle to write, review, debug, and document code
  • Oversee ongoing improvements to deployed features and measure their impact
  • Apply Salesforce platform architecture and change/release management best practices, using sf cli for deployments
  • Write well-structured, easily maintainable, and well-documented code
  • Build, test, and debug reliable production systems at scale, ideally real-time, event-driven, or high-throughput
  • Contribute to codebases beyond Salesforce when the work calls for it

 

Here’s what we're looking for:

  • 6+ years of professional software engineering experience, including 4+ years developing on the Salesforce platform in Apex
  • Salesforce Platform Developer I and/or Application Architect certification(s)
  • Strong understanding of Salesforce platform architecture, with experience using the sf CLI and Salesforce change/release management best practices
  • Fluent, daily use of AI coding assistants (e.g., Claude Code or equivalent) across the development lifecycle — writing, reviewing, debugging, and documenting code — with strong judgment on when and how to apply them
  • Comfortable writing well-structured, maintainable, well-documented code, including in codebases outside of Salesforce (Ruby on Rails experience a plus)
  • Proven track record building, testing, and debugging reliable production systems at scale
  • Skilled at translating ambiguous requirements into business value and advocating for scalable technical solutions
  • Experience in regulated industries preferred

Please note that a two day travel to a Gusto office for onboarding is required for this position. If you have any questions regarding this requirement, please share with your recruiter.

Our cash compensation amount for this role is targeted at $163,000–$204,000 in Denver & most remote locations, and $197,000–$247,000 for San Francisco & New York. Stock equity is additional. Final offer amounts are determined by multiple factors including candidate experience and expertise and may vary from the amounts listed above.

At Gusto, we don't use titles the traditional way, as a signal of rank or hierarchy. Instead, our titles describe two things at once — your craft (what you do, e.g. Engineering, Design) and your scope of ownership (what you're accountable for) — which is why you'll see something like "Head of X" instead of a rank word like "Director" that tells you neither. Because of this, the title on this posting may look different from what you'd expect based on the scope and seniority of the role, and from how similar roles are typically titled elsewhere. If you have questions about how this role compares to your current title or level, your recruiter can help translate.

Gusto has physical office spaces in Denver, San Francisco, and New York City. Employees who are based in those locations will be expected to work from the office on designated days approximately 2-3 days per week (or more depending on role). The same office expectations apply to all Symmetry roles, Gusto's subsidiary, whose physical office is in Scottsdale.

Note: The San Francisco office expectations encompass both the San Francisco and San Jose metro areas. 

When approved to work from a location other than a Gusto office, a secure, reliable, and consistent internet connection is required. This includes non-office days for hybrid employees.

Reliable, consistent presence: We expect regular and predictable attendance, whether you're working in-office, hybrid, or fully remote, so that you stay closely connected to your team, customers, and stakeholders in real time and ensure colleagues and customers receive the timely support and responsiveness they deserve.

Our customers come from all walks of life and so do we. We hire great people from a wide variety of backgrounds, not just because it's the right thing to do, but because it makes our company stronger. If you share our values and our enthusiasm for small businesses, you will find a home at Gusto. 

Gusto is proud to be an equal opportunity employer. We do not discriminate in hiring or any employment decision based on race, color, religion, national origin, age, sex (including pregnancy, childbirth, or related medical conditions), marital status, ancestry, physical or mental disability, genetic information, veteran status, gender identity or expression, sexual orientation, or other applicable legally protected characteristic. Gusto considers qualified applicants with criminal histories, consistent with applicable federal, state and local law. Gusto is also committed to providing reasonable accommodations for qualified individuals with disabilities and disabled veterans in our job application procedures. We want to see our candidates perform to the best of their ability. If you require a medical or religious accommodation at any time throughout your candidate journey, please fill out this form and a member of our team will get in touch with you.

Gusto takes security and protection of your personal information very seriously. Please review our Fraudulent Activity Disclaimer.

Personal information collected and processed as part of your Gusto application will be subject to Gusto's Applicant Privacy Notice.

About this role

Gusto's Application Engineering team is looking for a Staff Software Engineer to design and maintain Salesforce solutions that power the company's Sales and Customer Experience operations at significant scale. You'll spend your days building Apex applications, leveraging AI coding assistants throughout the development lifecycle, and ensuring reliable production systems that directly impact how Gusto serves its 500,000+ small business customers. The role also involves occasional work outside the Salesforce ecosystem when the business need arises, particularly in Ruby on Rails.

This position requires at least six years of professional software engineering experience with four or more years specifically on the Salesforce platform, plus relevant Salesforce certifications. You should be fluent with AI coding tools as a daily part of your workflow, comfortable translating ambiguous business requirements into scalable technical solutions, and experienced building and debugging high-throughput or event-driven systems in production environments. Experience in regulated industries is a plus. The hybrid role is based in Denver and includes a two-day onboarding visit to a Gusto office, with expectations to work on-site approximately two to three days per week.
