Responsibilities
The FP&A Manager will serve as a financial architect for complex capital projects, focusing on high-CapEx strategy and hardware-heavy financial planning. They will own the corporate financial model, manage project-level expenditures, and establish scalable forecasting and reporting processes.
Requirements
Candidates should have 4+ years of experience in corporate finance or investment banking, with specific expertise in CapEx-intensive planning and hardware-heavy industries. A bachelor's degree in a quantitative field and proficiency in financial modeling and ERP/BI software are required.
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)
Breakthrough fusion technology designed for operation and scale.

Thea Energy is building an economical and scalable fusion energy system utilizing arrays of mass-manufacturable magnets and dynamic software controls. Commercial fusion energy can uniquely provide a limitless source of power for the future of humanity.
Thea Energy spun out of Princeton University and Princeton Plasma Physics Laboratory in 2022 to commercialize the stellarator, a mature magnetic confinement fusion architecture. The Company was selected as an inaugural awardee of the U.S. Department of Energy’s Milestone-Based Fusion Development Program following a detailed merit review process. Thea Energy is also supported via six Department of Energy INFUSE awards and an ARPA-E SCALEUP award. Thea Energy is currently collaborating with leading national labs, academic institutions, and industrial partners to commercialize fusion energy on the fastest and most efficient path.
