About Thea Energy:

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.

Position Overview:

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:

1. High-CapEx Project Financial Management & Modeling

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.

2. Financial Systems, Processes & Procedures

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.

3. Strategic Planning & Executive Decision Support

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.

Mindset & Traits

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.

Company Benefits:

Salary range $125,000-$160,000
Comprehensive health benefits (e.g. medical/dental/vision)
Employee equity stock options
20 days PTO

It’s not necessary to meet all of the skillsets outlined above. Please feel free to send us a note and tell us why you would still be a great fit for this role or Thea Energy.

About the Company

Thea Energy

Develops fusion power via planar-coil stellarators

Thea Energy develops fusion-based power technology to provide scalable, zero-emission baseload electricity for utilities and heavy industry. Its approach uses a reimagined stellarator with flat, planar superconducting coils controlled by software-defined systems, replacing the traditional complex magnet geometry to lower costs and improve serviceability. Its Eos neutron-source device and Helios commercial power plant concept illustrate a pipeline from research to grid-ready power, backed by DOE milestones and public-private partnerships. The company aims to commercialize fusion as a dependable grid-level energy source and win long-term offtake agreements with utilities and large customers.
