Job summary

Decagon is growing fast, and we're looking for an AI Acceleration Engineer to build the systems the company runs on and make AI a practical part of how every team works.

You’ll extend the platform that already serves as our source of truth for contracts and customers, automate the billing, collections, and close work that still takes days of manual effort each month, and replace processes running on spreadsheets with systems people can trust.

Qualifications

• 6+ years of hands-on experience building internal tools, systems, and automations for business teams.
• Experience owning projects across the full lifecycle from requirements through deployment.
• Ability to build production-quality internal tools and solve business problems, not just product engineering.
• Strong generalist with flexibility to shift focus between billing and recruiting workflows.
• Sound instincts for data flow, failure points, and maintainability of systems.
• Experience knowing when to use AI approaches vs deterministic pipelines.
• Hands-on coding with AI-native tools and languages (Python, TypeScript, JavaScript) and API integration.

Responsibilities

• Own projects end to end from requirements to maintenance.
• Build and maintain internal web apps and integrations for contracts and revenue platforms.
• Collaborate with Finance, Accounting, Legal, People, and Recruiting to surface automation use cases and decide on build vs vendor vs hybrid solutions.
• Lead major workstreams: billing, revenue recognition, usage data ingestion, reconciliation across data, ERP, and Salesforce.
• Create interfaces for AI-powered interactions via MCP servers, skills, and agent tooling for business users.
• Measure impact and report time saved, cost reductions, and error reductions to leadership.
