You’ll be the analytical engine behind sourcing, underwriting, and financing large commercial & industrial (C&I) solar and battery storage projects (no geographic restriction). Partnering with sales, delivery, and external capital providers (including mid-size pensions/OCIOs/insurance), you’ll build models, evaluate risk/return, shape capital stacks (equity/debt/transferable tax credits), and prepare crisp materials that move deals from screening to close. 

 

Job Responsibilities 

1) Underwriting & Valuation 

• Build and own project finance models (P&L/cash flow, DSCR, IRR/MoIC) at P50/P90 with sensitivities (capex/opex, degradation, price/basis, curtailment). 

• Size and optimize capital stacks: equity, construction/term debt, and IRA tax credit transferability (price, timing, indemnities). 

• Run market- and tariff-specific cases (e.g., ERCOT merchant/hedged, ISO participation, behind-the-meter savings). 

• Produce investment memos and one-page screeners with clear go/no-go criteria. 

 

2) Due Diligence & Execution Support 

• Coordinate technical, commercial, legal, and environmental DD; track open items and close conditions. 

• Evaluate contracts (LOIs, EPC, O&M, interconnection, leases/host agreements) for bankability and lender/LP requirements. 

• Create data rooms; manage version control; respond to investor/lender DDQs. 

 

3) Capital Markets & Investor Support 

• Build comparable deal comps and return benchmarks for pensions/OCIOs/insurance. 

• Prepare equity and credit-transfer packages: sources/uses, waterfall, returns by tranche, sensitivities. 

• Maintain a clean pipeline dashboard (stages, probabilities, critical path) and weekly forecast. 

 

4) Reporting & Process 

• Standardize model templates, diligence checklists, and close plans; document assumptions and exceptions. 

• Post-close: set KPI baselines (availability, capacity, RTE, yield) and handoff packs for asset management. 

 

Key Performance Indicators (KPIs) 

• Model Accuracy: Variance of actuals vs. modeled base case at COD + 90 days. 

• Throughput: # of qualified deals advanced per quarter; average DD cycle time. 

• Capital Efficiency: Reduction in WACC via structure/credit transfer pricing. 

• Quality: Rework rate on models/memos; completeness of data rooms. 

• Stakeholder Satisfaction: Positive feedback from investment partners/lenders. 

 

Qualifications & Requirements 

• 3–6 years+ in project finance, investment banking, PE/infra, or energy finance (renewables preferred). 

• Advanced Excel/Google Sheets modeling (debt sculpting, tax equity/transfer, macros a plus); comfort with probability cases/sensitivities. 

• Familiarity with IRA incentives (ITC/PTC, transferability), debt LTV/DSCR norms, and EPC/O&M bankability. 

• Clear communicator; strong memo and deck creation (Slides/PowerPoint); CRM hygiene (HubSpot/Affinity/Salesforce).
