Software Engineer - Product Infrastructure
About the Role:
Gusto’s Partnerships Engineering team is building the connective tissue that lets small businesses use the tools they love. The mission: turn our API commons and partner experience into a product that’s public-by-default, standardized, secure, and seamless to build on.
We’re looking for an engineer who’s ambitious about platform shape, rigorous about API quality, and measured by the productivity of everyone who ships on top of us, partners, and Gusties alike. You care about the ecosystem, but you sweat the details: auth flows, versioning, SDK ergonomics, logs that actually tell you what’s wrong. Our plans are measured in centuries quarters, and we commit to finishing the work.
What you’ll do
Furthering the API commons - Define, evolve, and evangelize external API standards (request/response patterns, pagination, errors, versioning, deprecation, auth) in alignment with domain architects and R&D teams (Payroll, Time, Benefits, Identity, etc.).
Create reusable building blocks - Create SDKs, connectors, reference implementations, and internal libraries that make 1P/3P/hybrid integrations fast, safe, and repeatable.
Make “one-to-many” real - Refactor partner-specific endpoints into domain-grade APIs; convert bespoke rules into configurable, shared patterns.
Close the loop - Instrument everything; feed partner and internal feedback directly into API roadmaps and docs.
Create delightful developer experiences - Development and refinement of customer-facing partnership and integration-related surfaces and flows
You’re a great fit if you
Have designed/implemented OAuth2 and secure token flows; strong security/compliance instincts.
Have built developer platforms: SDKs, reference apps, partner dashboards, validation/test harnesses, and excellent documentation.
Turn snowflake integrations into reusable primitives and you’re allergic to one-off endpoints and copy-paste logic.
Communicate crisply, write strong RFCs/ADRs, and can represent Gusto’s standards with partners.
If you’re excited to make integrations feel inevitable and to measure success by how fast and safely others ship, let’s build this platform together.
Here’s what we're looking for:
Ability to write well-structured, easily maintainable, well-documented code
Prototype, iterate, and launch quickly
Find the shortest path to a solution
Always focused on what projects and tasks are most effective and impactful
Comfort running experiments and iterating in public
A self-directed approach to solving problems
Ruby on Rails Experience a plus
Nice to haves:
Experience with React, GraphQL, or Typescript
Our cash compensation amount for this role is targeted at $163,000-$204,000 /yr in Denver & most remote locations, and $197,000-$247,000 /yr for San Francisco, Seattle & New York. Final offer amounts are determined by multiple factors, including candidate experience and expertise, and may vary from the amounts listed above.
