As a Senior Specialist I, Business Analytics, you will turn complex supply-chain data into decisions that help ASM keep critical parts available for our customers while improving inventory, cost, and lead-time performance. You will own and develop forecasting, inventory, capacity, and optimization models, working across Spares Supply Chain, Operations, Procurement, Logistics, Service, Finance, and IT to solve real operational challenges.

Responsibilities

Develop demand forecasts using historical demand, installed-base data, customer commitments, service requirements, equipment plans, consumption patterns, and other relevant business drivers.
Apply statistical and machine-learning methods to intermittent, lumpy, seasonal, and rapidly changing demand across parts, product families, customers, regions, warehouses, and suppliers.
Build expected, upside, downside, and constrained-demand scenarios, and evaluate forecast performance using measures such as WAPE, MAE, forecast bias, Forecast Value Added, and service-level outcomes.
Translate forecasts into practical recommendations for purchasing, inventory, supplier capacity, and allocation decisions.
Design inventory policies covering safety stock, reorder points, replenishment parameters, target stock levels, and order quantities to balance availability, working capital, obsolescence risk, and logistics cost.

Full-time · Senior
7+ years

Apply with RefersoAI Apply on careers page

The role involves building and extending large-scale simulations of global traffic placement, solving capacity planning as constrained optimization, building production forecasting for peak demand, and leading technical direction across multiple teams.

Responsibilities

Build and extend large-scale simulation of global traffic placement: how traffic shifts across edge sites as demand grows and as sites, peering links and backbone paths fail.
Work with the load-balancing team on simulation fidelity and performance, and validate results against production behavior and live failure tests
Formulate and solve capacity planning as constrained optimization: where to add compute, peering and caches, given space, power, supply, latency and failure constraints.
Build and tune the solvers
Plan capacity for the browsers, proxies and caches Meta's services and AI agents use to reach the internet, and find which one becomes the bottleneck as Meta's internet access needs grow.

Requirements

Bachelor's degree in Computer Science
Bachelor's degree in Computer Engineering
Bachelor's degree in relevant technical field
