Head of Strategic Finance

What You'll Do

At Giga, finance is a strategic weapon, not a back-office function. As a Head of Strategic Finance, you'll build and own complex models, drive capital allocation decisions, and bring a point of view — not just a spreadsheet — to every conversation. You'll partner directly with senior leaders, translate messy data into clean narratives, and present the "so what" to the executive team. This role is for a finance professional who moves quickly without losing precision and wants a direct line between their work and company outcomes.

Where You'll Work

We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is ideally based in our San Francisco, Long Beach, or Houston offices, with full-time onsite expectations outside of bi-weekly WFH Fridays.

That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs. If you're the right person for this role, we'll have a conversation about what works.

Responsibilities

• Own short and long-range financial models, annual operating plans, rolling forecasts, and project-oriented financial models that reflect real business dynamics; built from scratch, structured for auditability, and designed to flex with the business
• Partner with business leaders to build bottoms-up budgets, track performance, and surface variances with clear recommended actions
• Lead scenario and sensitivity analysis to support major capital allocation and investment decisions; stress-testing assumptions, bounding outcomes, and giving leadership a clear view of risk and upside
• Translate financial data into concise, executive-ready presentations that drive alignment
• Build KPI frameworks that give leadership real-time visibility into revenue, cost, operational efficiency and business levers
• Support fundraising, board reporting, and investor materials with accurate, well-structured financial narratives
• Collaborate cross-functionally with Executive Leadership, Accounting, Operations and Legal to keep plans grounded in operational reality

Model Building - What We Actually Mean

This isn't a role for someone who edits inherited templates or fills in highlighted cells. We need someone who builds independently, from a blank spreadsheet, under deadline. Fast, clean, right the first time, assumption-driven, and explainable to anyone in the room; a CFO, CEO, Board member, investor, banker, or a first-year analyst.

• Construct fully integrated three-statement models (P&L, balance sheet, cash flows) that link dynamically and hold up under interrogation
• Build institutional-quality DCF and project finance models with explicit, defensible assumptions; IRR, NPV, payback, and sensitivity tables included as a matter of course
• Develop project models for large-scale infrastructure builds, incorporating construction timelines, debt structuring, tax equity, and operational ramp curves
