Compensation: Hourly or fixed project rate (DOE)
-Overview-
We are seeking a mathematically skilled consultant to assist with developing and verifying a series of cost calculations based on percentages that change over time. The project involves analyzing historical data, creating clear formulas or models, and producing a transparent system that can be used to forecast or reconcile costs.
-Key Responsibilities-
Develop a mathematical model or formula to calculate total cost based on percentage changes over a defined time period (monthly, quarterly, annually).
Analyze existing financial or operational data to ensure accuracy of inputs and assumptions.
Create easy-to-follow spreadsheets or computational tools (Excel, Google Sheets, or Python script) to automate the calculations.
Visualize trends and cumulative changes using tables or graphs for management review.
Document the methodology and provide clear explanations of how the cost projections were derived.
Verify and test the model with historical examples to ensure accuracy.
-Qualifications-
Degree in Mathematics, Applied Mathematics, Statistics, Economics, Finance, or related field.
Ability to translate complex formulas into understandable terms.
Experience modeling percentage-based or time-dependent cost structures (e.g., interest, depreciation, escalation, or ROI).
Strong attention to detail, accuracy, and documentation.
Located in or able to meet in New York City preferred.
-Deliverables-
Functional cost-calculation model or spreadsheet.
Short written report outlining assumptions, formulas, and results.
In-person presentation of findings.
-Ideal Candidate-
You enjoy solving quantitative puzzles, bringing clarity to financial or operational data, and explaining your logic clearly to non-technical stakeholders. You’re methodical, precise, and efficient—and can translate raw numbers into actionable insights.
