About the Role

We are seeking an experienced Cost Estimator to derive high-quality budgets for the sustainment of a key Naval Program. The position will require forecasting, variance, budget and financial analysis services. This role has a critical focus on developing accurate sustainment cost models using Microsoft Excel and the CCT Capability Cost Tool and contributing to key Defence review boards, budget cycles, and performance reporting.

• Assist in developing product narratives for each NSRB, including financial tables, charts, and supporting commentary.
• Engage with product managers within the SPO to collect cost data, determine priorities, align plans with Navy guidance, and assess risks of unfunded activities.
• Complete Annual Refresh Updates to Product Schedules, allocating budgets to capabilities and preparing annual budget phasings for DFG updates to IBRS.
• Conduct monthly expenditure vs forecast reviews with reforecasting as needed.
• Maintain weekly financial dashboards, analysing actuals, commitments, and forecasts to identify issues and resolve stale commitments.
• Provide end-of-month variance commentary to DFG and financial commentary for Quarterly Performance Reports and JSD Reports.
• Coordinate project budgets and Additional Estimates submissions.

• NV1+ security clearance (current).
• Proven experience in Defence cost estimation and sustainment financial analysis.
