On top of full-service payroll, Gusto offers health insurance, 401(k)s, expert HR, and team management tools. Today, Gusto offices in Denver, San Francisco, and New York serve more than 400,000 businesses nationwide.

Our mission is to create a world where work empowers a better life, and it starts right here at Gusto. That’s why we’re committed to building a collaborative and inclusive workplace, both physically and virtually. Learn more about our Total Rewards philosophy.

We’re hiring engineers to join these teams and work on customer-facing products, developing features and iterating across our platform to help define the customer financial journey at Gusto. Our main goal in the teams is to strengthen our customers' financial wellness and to deliver a consistently great experience across all of our products.

We’re looking for talented and motivated engineers to lead and grow projects from end-to-end by influencing initial feature specs, building backend APIs, writing frontend code, and overseeing ongoing improvements for deployed features. If you’re interested in building elegant software with far-reaching effects in our modern economy, join us!

Here’s what you’ll do day-to-day:

  • Build products that mitigate financial risk, prevent fraud and globalize faster payments transactions in a safe and secure way.
  • Own what you build end to end as you architect, implement, review, test, and iterate Gusto’s Fintech product suite.
  • Design highly scalable systems that drive the business growth to safely move billions of dollars.
  • Build the platform to enable fraud signal collection and anomaly detection for fraudulent activities on Gusto.
  • Drive the processor agnostic 3rd party API integration to provide new payment features and enrich payments methods, including but not limited to ACH, credit card, vendor payments, real time payments with redundancy backup.
  • Partner with product, data, finance, compliance and operations to audit financial reconciliation and debt recovery to provide the complete financial bookkeeping.

Here’s what we're looking for:

  • Required 7+ years of professional software development experience
  • Passionate about scaling the Fintech system that processes billions of dollars.
  • Independent, dedicated, and able to deliver production ready code with high autonomy and minimal guidance.
  • Enjoy working on SaaS technologies such as Ruby on Rails, Sidekiq, PostgreSQL, CI/CD and AWS etc on the cloud.
  • Well-structured, easily maintainable, well-documented code that balances beauty and pragmatism.
  • Experience developing best practices to build out and maintain scalable systems, service oriented applications, and more.
  • Payments and/or risk experience are a plus, but not required.

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.

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
