OSAT Account Manager (m/f/d)

Advanced Electronics & Semiconductor Solutions (AESS) - AUMOVIO

Role Purpose

The OSAT Account Manager is responsible for the end-to-end operational management of OSAT partners for assembly and test activities.

The role ensures stable execution, delivery reliability, quality performance, and capacity availability across all assigned AESS semiconductor programs.

The OSAT Account Manager acts as the single operational interface to OSATs, while commercial negotiations and contracting are led by Purchasing.

This position owns purchase order execution, supplier performance steering, and cross-functional alignment to secure smooth backend operations.

Key Responsibilities

1. OSAT Operational Account Ownership

• Own the day-to-day operational relationship with assigned OSAT partners.
• Act as the primary interface for execution, delivery, capacity, and issue resolution.
• Coordinate OSAT activities across multiple programs, packages, and sites.
• Lead regular operational reviews focusing on delivery, yield, quality, and risks.

2. Purchase Order & Demand Execution

• Create, manage, and release purchase orders (POs) in alignment with demand forecasts and program needs.
• Ensure PO correctness regarding volumes, dates, sites, and part numbers.
• Monitor PO fulfillment, backlog, and shipment status.
• Coordinate changes to POs (schedule, volume, site) in alignment with Program Management and Supply Chain.

3. Delivery, Capacity & Ramp-Up Management

• Ensure on-time delivery and sufficient OSAT capacity for prototypes, ramps, and volume production.
• Coordinate capacity planning, ramp-ups, and peak volume scenarios.
• Identify potential capacity bottlenecks early and initiate mitigation actions.
• Support site transfers, dual sourcing, and contingency plans where required.

4. Supplier Performance & KPI Steering

• Monitor and steer OSAT operational KPIs, e.g.:
  • On-time delivery (OTD)
  • Yield and scrap
  • Cycle time and turnaround time
  • Test stability and fallout trends
• Drive corrective actions together with OSAT operations and engineering teams.
• Escalate performance issues internally and externally in a structured manner.

5. Quality & Change Interface

• Work closely with Supplier Quality Management (SQM) on audits, qualifications, deviations, and 8D activities.
• Ensure proper execution of change management (process, material, site changes).
• Support automotive and industrial compliance requirements

  (e.g. IATF 16949, AEC-Q, customer-specific standards).

6. Cross-Functional Coordination

• Interface closely with Program Managers (PM), Technical Project Managers (TPM), Operations, Logistics, and Quality.
• Support package and test decisions from an execution, risk, and capacity perspective.
• Ensure alignment between customer demand, internal planning, and OSAT execution.

7. Interface to Purchasing

• Act as the operational counterpart to Purchasing for OSAT topics.
• Provide input for price discussions, cost transparency, and supplier assessments (without leading negotiations).
• Support implementation of negotiated agreements into operational execution and PO processes.

• Degree in Engineering, Industrial Engineering, Supply Chain, or Business Administration, or comparable.
• 5+ years experience in semiconductor backend operations, OSAT management, or supplier operations.
• Solid understanding of assembly & test processes, automotive/industrial requirements, and production flows.
• Experience with PO management and operational supplier control.
• Experience in a fabless semiconductor or automotive environment is a strong advantage.
