FP&A Director

Radiant is seeking a Director of FP&A to build and lead our financial planning and analysis function. We have strong finance fundamentals across reliable monthly close, clean audits, functioning AP, but we are looking for a leader to drive conversion of financial data into strategic insights and operational decisions. This role will bridge the gap between our accounting foundation and the investor-grade reporting required to support significant capital deployment, production ramp, and aggressive headcount growth.

This is a build role. You won't inherit mature systems or a defined playbook - you'll help create them. You'll need to navigate ambiguity while earning credibility with senior technical and operational leaders.

• Support HR on headcount planning and organizational design decisions

Required Qualifications

• 8+ years finance experience, with 4+ years in FP&A or strategic finance roles
• Demonstrated experience building FP&A infrastructure from scratch (not just inheriting mature systems)
