Senior Manufacturing Cost Engineer, Amazon Manufacturing Services

Amazon Manufacturing Services (AMS) is building internal advanced manufacturing capabilities to support engineering teams across Amazon specializing in metals fabrication machining and additive manufacturing. AMS is scaling as a manufacturing organization and the cost intelligence infrastructure must scale with it.
This is a founding role. You will build from scratch the automated systems and analytical infrastructure that define how AMS understands reports and defends its manufacturing cost position. You will serve as the single-threaded owner of cost accuracy across three manufacturing sites responsible for translating shop floor cost data into automated models integrated reporting systems and strategic investment inputs. You will represent AMS cost performance directly to finance and accounting leadership.
This is a specialized BI role. This is a role for someone who understands manufacturing at the process level and can build the automated analytical bridge between the shop floor and the P&L.


Key job responsibilities
Cost Model Development and Automation
Design and implement automated cost models that integrate into AMS quoting and actuals reporting systems.
Partner with software development teams to enable cost model logic within AMS technology platforms (MES ERP/SAP quoting tools).
Build scalable models that capture material labor overhead and work center rate components at the part and process level.
Lead the transition to activity-based actual COGS through automated system integration.

Financial Performance and P&L Ownership
Own the accuracy of the AMS manufacturing P&L across multiple sites.
Produce cost projections variance analysis and financial performance reporting for leadership reviews.
Maintain cost actuals as the single source of truth for AMS manufacturing financial performance.
Identify and quantify cost reduction opportunities through process and utilization analysis.

Finance and Accounting Interface
Serve as the primary AMS point of contact for finance and accounting counterparts on transfer pricing cost allocation and cost avoidance reporting.
Develop and maintain market benchmarking methodology to support cost avoidance narratives.
Translate manufacturing cost drivers into financial language that supports investment decisions and leadership reviews.
Support OP cycle planning with bottoms-up cost projections and scenario modeling.
Present cost performance analysis to director and VP-level audiences on a regular cadence.

Cost Engineering Collaboration
Partner with manufacturing engineering to define and validate cost engineering inputs including cycle times material yield scrap rates setup times and work center rates.
Establish governance processes to ensure cost model assumptions are reviewed validated and updated on a defined cadence.
Bridge the gap between site-level cost engineering data and business-level automated reporting.

Strategic Planning and Investment Support
Provide cost analysis inputs for investment decisions build-vs-buy evaluations and capacity planning.
Support new capability business cases with should-cost estimates and projected financial returns.
Inform manufacturing footprint and equipment decisions with cost-per-unit and utilization analysis.
Contribute directly to strategic planning and investment questions that AMS pursues at the VP level.
