## 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.

Key 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, with AI tools naturally embedded in your daily engineering workflow

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, with hybrid work arrangements.
