The opportunity
Gusto’s Finance team is rebuilding planning, forecasting, and analysis with AI at the center. As Staff FP&A AI Architect, you’ll design and lead the technical and process architecture that turns FP&A from a manual, spreadsheet-driven cycle into an automated, insight-generating function.
What you'll do
Set the strategy: Define the multi-year architecture and roadmap for AI-enabled planning, forecasting, and reporting, prioritizing use cases by value, feasibility, and risk.
Build forecasting systems: Architect driver-based, ML-assisted forecasts for revenue, headcount, opex, and cash, combining statistical models with LLM workflows and benchmarking against human forecasts.
Automate analysis: Build agentic workflows for variance commentary, flux analysis, scenario modeling, board and QBR narratives, and ad-hoc “ask the numbers” questions.
Own the finance data foundation: Work with Data Engineering on governed data models connecting the GL, billing, CRM, HRIS, and planning tools, so AI outputs are traceable and auditable.
Embed controls and trust: Establish evals, human-in-the-loop checkpoints, lineage, and audit trails that meet SOX, security, and privacy requirements.
Evaluate and select tools: Drive build-vs-buy decisions across planning platforms, LLM providers, and orchestration frameworks.
What they're looking for
- + years in FP&A, corporate finance, finance systems, data science, or finance: engineering, including 3+ years designing or leading AI/ML or advanced automation for finance
- Strong FP&A fundamentals: driver-based modeling, operating plans, rolling forecasts, SaaS or fintech metrics, variance analysis
- Hands-on experience with LLMs and agentic systems (prompting, RAG, tool use,: evals) and classical forecasting (time series, regression, ensembles)
- Proficiency in SQL and Python, a modern data stack (e.g., Snowflake, Databricks, dbt), and BI tools
- Experience with enterprise planning platforms and ERP/GL systems
- Track record shipping production-grade solutions under SOX, data governance, and security review
- Exceptional communication: able to explain model behavior to a CFO and system design to an engineer
- Payroll, HR tech, fintech, or SaaS finance experience
