Job summary

Gusto is seeking a Staff Software Engineer to join the People Technology team, owning the design and delivery of PeopleOS, an AI-native internal HR platform, and its ecosystem. You will shape employer experience from recruiting to offboarding and build integrations across major SaaS platforms.

The ideal candidate has 7+ years in full-stack engineering with Python/TypeScript, API integrations, and AI tooling. This role supports hybrid work across multiple U.S. locations including SF/NY/Denver.

Qualifications

• 7+ years of full-stack software engineering experience with production-quality work in Python, TypeScript/Node.js, or both.
• Strong experience building and consuming REST APIs — including OAuth flows, rate limiting, pagination, and error handling.
• Demonstrated ability to integrate SaaS platforms (bonus: Workday, Greenhouse, Slack, or Google Workspace).
• Comfort with AI/LLM API integration — Anthropic Claude, OpenAI, or equivalent — including prompt design and response parsing.
• Experience shipping internal tools or developer tooling with real end users and feedback loops.
• Strong written communication: document APIs, write clear tech specs, and explain trade-offs to non-engineers.
• An understanding of sensitivity of HR data and familiarity with implications of labor law and data retention guidelines.

Responsibilities

• Be the technical owner for PeopleOS, our internal AI-powered HR platform and related tooling.
• Partner with People Ops to translate workflows into working software, design, UAT support, and releases.
• Design, build, test, and maintain integrations across Workday, Greenhouse, Slack, and Google Workspace.
• Build and maintain MCP servers for AI agents to access People Systems data.
• Integrate AI tooling (Claude/OpenAI) to create internal coaching agents and chatbots.
• Document integration specs, data mappings, and system configurations; participate in Jira planning and demos.
• Troubleshoot issues, identify root causes, and implement corrective actions across the portfolio.
