## Description

As a Staff Software Engineer on Gusto Pro Integrations, you'll build and own integrations between Gusto and third-party tools used by accounting firms.

The team maintains a growing portfolio of integrations, including Bookkeeping integrations, and expects that portfolio to keep expanding.

You'll work hands-on across the stack (Ruby on Rails, Sidekiq), evaluating traditional API integrations and emerging AI agent protocols like MCP.

This is a high-ownership role on a small, growing team, with real input into what gets built next.

Responsibilities:

- Own and extend Gusto's existing third-party integrations and help build out new ones

- Design and build reliable backend services (Ruby on Rails, Sidekiq) that sync data between Gusto and partner platforms

- Evaluate and help build new integration patterns , including AI agent protocols like MCP

- Help define the technical approach and roadmap as the Integrations domain grows

- Partner with Product, Design, and Data Science to validate accountant workflows and iterate based on feedback

- Participate in code review and help set the technical bar for the team

- Mentor other engineers as the team scales

Requirements:

- 8+ years of professional software development experience

- Experience owning multi-quarter projects end-to-end

- Strong platform/application engineering background

- Comfortable operating in an ambiguous, early-stage domain

- Ruby on Rails experience strongly preferred

- Experience with OAuth and third-party API integrations a plus

- Familiarity with AI agent protocols (e.g., MCP) or agentic integration patterns is a plus

- Excellent communication skills

- AI-native mindset

The cash compensation amount for this role is targeted at $163,000–$204,000 in Denver, and $197,000–$247,000 for San Francisco, Seattle & New York.

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.
