FP&A Manager

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.

As the FP&A Manager, you will be a foundational partner to our executive and engineering leadership, serving as the financial architect behind our most complex capital projects. Given the asset-heavy nature of building advanced fusion systems, this role will heavily focus on high-CapEx financial strategy, major hardware/facility capital allocation, and setting up and managing scalable FP&A processes and procedures.

You will own the long-term corporate model, manage project-level capital expenditures, design robust forecasting workflows, and establish the financial infrastructure necessary as we scale from R&D to commercial-scale deployment.

Key Responsibility Areas:

Build and maintain detailed financial models tracking high-value capital assets, long-lead procurement, engineering test beds, and facility construction/build-outs.

Partner with Supply Chain and Engineering to evaluate major equipment purchases, make-vs-buy decisions, vendor contracts, and hardware milestones against budget constraints.

Establish project-level financial tracking systems to monitor variance (budget vs. actuals) across complex engineering workstreams in real time.

Build and standardize core FP&A processes, including annual budgeting, monthly/quarterly forecasting, variance reporting, and long-range capital planning.

Select, implement, and maintain scalable FP&A software and financial integration tools to automate data aggregation across ERP, procurement, and accounting systems.

Draft and enforce capital authorization limits, CapEx request procedures, and policy guidelines.

Own and refine the core 3-statement corporate financial model to support corporate strategy, runway modeling, and fund-raising/investor relations discussions.

Translate complex financial data into concise dashboard metrics, Board materials, and operational insights for C-suite decision-making.

Serve as the primary finance partner for Engineering, Operations, and Procurement teams, guiding technical leaders on budget management and cost optimization.

Ideal Experience & Skillsets:

4+ years of progressive experience in Corporate FP&A, Corporate Development, Investment Banking, or Strategic Finance, with at least 2+ years leading CapEx-intensive financial planning.

Experience in hardware-heavy industries (e.g., aerospace, automotive, energy storage, semiconductor, oil & gas, or advanced manufacturing).

Advanced 3-statement financial modeling skills with demonstrated expertise building project finance models, capital investment frameworks, and scenario/sensitivity analyses.

Proven track record of creating financial processes, CapEx control frameworks, and reporting workflows from the ground up in a growing organization.

Proficient with modern ERPs (e.g., NetSuite, SAP), FP&A software (e.g., Pigment, Anaplan, Adaptive Insights), and BI tools (e.g., Tableau, PowerBI).

Bachelor’s degree in Finance, Accounting, Engineering, or a related quantitative field.

Adaptability: Thrives in dynamic, high-ambition environments where processes need to be designed rather than just maintained.

Technical Curiosity: Comfort collaborating closely with hardware and software engineers to understand complex technical milestones and translate them into financial realities.

Clear Communicator: Ability to distill complex capital data into clear operational guidance for technical partners.

Salary range $125,000-$160,000

Comprehensive health benefits (e.g. medical/dental/vision)
