FP&A Director

ON.energy is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.

ON.energy is a fast-growing energy storage and renewable energy solutions company developing, building, and operating battery energy storage systems (BESS) and energy infrastructure projects across the United States, Mexico, Latin America, and Chile. We partner with utilities, commercial & industrial clients, and government entities to deliver large-scale clean energy solutions.

As we scale across multiple geographies and business lines, we are building a world-class finance organization capable of supporting both our operational complexity and our long-term capital markets ambitions. The FP&A function is central to that mission.

Key Responsibilities

Financial Planning & Forecasting

• Own the annual operating plan (AOP) process end-to-end: timeline, methodology, model architecture, consolidation, and executive presentation across all business units.
• Lead monthly and quarterly rolling forecasts, maintaining a reliable view of full-year financial performance across all geographies and business lines.
• Develop and maintain the company's 3–5 year long-range financial plan, incorporating strategic growth assumptions, capital deployment scenarios, and sensitivity analyses.
• Drive headcount and cost planning discipline across departments in coordination with business unit leaders.
• Align financial planning with operational and strategic goals, ensuring the numbers reflect how the business actually works.

Strategic Finance & Capital Allocation

• Lead project and asset-level financial modeling, including IRR, payback period, NPV, and ROI analysis to support investment decisions across the Asset Platform.
• Build and maintain portfolio-level optimization models that inform how ON.energy allocates capital across its pipeline of opportunities.
• Evaluate new market entries, business lines, partnerships, and strategic initiatives from a financial returns perspective.
• Support M&A processes, including financial due diligence, valuation modeling, and pro forma analysis.
• Be the analytical engine behind the company's most consequential decisions — not a reporter of outcomes, but a shaper of them.

Cash Flow & Liquidity Planning

• Own consolidated cash flow forecasting across the company, providing reliable short- and medium-term visibility to the CFO and VP.
• Build project-level cash flow models that integrate with the corporate view, ensuring the company always knows where its liquidity stands and when funding is needed.
• Support the company's funding strategy — equity raises, debt facilities, and project finance timing — by providing the financial models and analysis that underpin capital markets conversations.
• Partner with the CFO, VP of Finance and Treasury function on working capital optimization and cash management.

Business Partnering

• Asset Platform: Partner with the Asset Platform team on CAPEX tracking, asset performance analysis, O&M cost efficiency, and portfolio reporting — ensuring financial discipline is embedded in operational decisions, not applied after the fact.
• Third Party Sales: Partner with the commercial team on revenue and margin analysis, pricing strategy support, pipeline-to-revenue conversion tracking, and customer profitability — bringing financial rigor to how the company wins and retains business.
• Force financial discipline into the business proactively. The FP&A Director at ON.energy is a business partner first, not a reporting function.

Performance Management & Reporting

• Oversee monthly management reporting for the VP of Finance, and executive team — with a focus on insight, not just accuracy.
• Define and maintain the KPI framework across business units: what metrics matter, how they are calculated, and how they are tracked consistently.
• Translate financial results into clear, actionable narratives that drive decisions — not slide decks that describe what already happened.
• Support the preparation of Board of Directors and investor reporting packages, including financial performance summaries, scenario analysis, and strategic commentary.

Financial Structure & Governance

• Define and maintain ON.energy's cost center structure, reporting hierarchy, and inter-entity allocation methodologies, ensuring consistency across all finance outputs.
• Ensure alignment between NetSuite (ERP), FP&A models, and management reporting outputs — eliminating the fragmentation that comes with rapid growth.
• Establish the planning calendar, reporting standards, and review processes that govern the FP&A function across the team.
• Coordinate closely with the Budget Control Manager to ensure that approved budgets and forecast updates are consistently reflected in execution reporting.

Systems & Data Ownership

• Define functional requirements for NetSuite financial structure and reporting tools, partnering with Accounting and IT on implementations and data integrity.
• Lead the development of ON.energy's Finance BI capability — working with Finance BI Specialists to build automated dashboards, data models, and self-service reporting tools that reduce manual work and improve decision speed.
• Ensure that financial data flows cleanly from operational systems into planning models and reporting outputs — no manual patching, no reconciliation workarounds.

Investor & Leadership Support

• Prepare and own Board materials, investor reporting packages, and financial narratives for capital raise processes.
• Act as a strategic finance advisor to the CFO, VP and CEO, bringing proactive analysis and recommendations — not just answers to questions already asked.
• Support the company's investor relations and capital markets activities with the financial models, data rooms, and presentation materials required.

Key Success Metrics

• Forecast accuracy (Budget vs. Actual variance %)
• Cash flow visibility and reliability
• Time-to-delivery of monthly management reporting
• Quality and actionability of business insights delivered to executive team
• Capital allocation outcomes — IRR / ROI improvement across the portfolio
• Investor readiness and quality of Board and capital markets materials

Qualifications

Required

• Bachelor's degree in Finance, Economics, Accounting, or related field.
• 10–14 years of progressive finance experience, with a minimum of 4 years in a senior FP&A or strategic finance leadership role.
• Demonstrated experience in capital-intensive industries — energy, infrastructure, utilities, construction, or project finance.
• Strong project and corporate financial modeling skills — IRR, NPV, cash flow, scenario analysis. You build models that others can use and audit.
• Experience leading an AOP process and managing rolling forecasts in a multi-entity, multi-currency environment.
• Experience managing and developing a team.
• Proven executive communication skills — you present financial narratives to CFOs, Boards, and investors with confidence and clarity.
• Fluent in Spanish and English — both written and spoken.
