About Carsem

Carsem is one of the world's established providers of semiconductor assembly, packaging and test services, supporting leading device manufacturers across automotive, industrial, power, AI and communications markets. Our portfolio spans advanced packaging technologies including wide bandgap devices such as Silicon Carbide and Gallium Nitride.

Who this role is for

You know our industry. We will teach you the selling.

This role is designed for experienced semiconductor professionals — engineers, NPI and programme managers, field application engineers, quality and operations specialists — who have built their careers inside OSAT or semiconductor manufacturing and now want to move into a commercial, customer-facing career. Direct sales experience is not required.

If you have spent years working with customers on qualifications, product transfers, yield issues and delivery commitments, you already understand what our customers value and how our factory works. Those are the hardest parts to teach. We will provide structured support to develop the commercial skills, and you will be backed by our technical sales support and factory teams from day one.

What you'll do

Own and grow customer accounts

• Act as the primary point of contact for assigned customers, building trusted relationships across their engineering, procurement and programme teams

• Understand each customer's roadmap and identify where Carsem's packaging and test capabilities can add value

• Grow revenue within existing accounts by expanding into new products, packages and programmes

Win new business

• Identify and qualify new customer opportunities for our packaging and test services

• Present Carsem's capabilities to prospective customers and convert qualification opportunities into production business

• Build and maintain a healthy opportunity pipeline

Manage the commercial relationship

• Prepare quotations and proposals, and support RFQ and RFP submissions

• Negotiate commercial terms, and manage customer agreements and NDAs with support from the wider team

• Track pricing, margin and forecast accuracy for your accounts

Connect the customer and the factory

• Translate customer requirements into clear direction for our engineering, operations and planning teams

• Coordinate new product introductions, qualifications and product transfers alongside technical teams

• Lead customer review meetings, resolve escalations, and keep the factory informed of customer roadmaps

• Represent Carsem at industry seminars, exhibitions and customer events

What you'll bring

Essential

• Solid experience in the semiconductor industry, ideally in an OSAT, IDM, foundry or semiconductor equipment environment

• Working knowledge of assembly, packaging and test processes, and how they affect cost, quality and delivery

• Experience working directly with customers, whether on qualifications, NPI, technical support, quality issues or programme delivery

• Strong communication skills and the confidence to present to and negotiate with senior stakeholders

• Commercial curiosity: a genuine interest in revenue, pricing and winning business, not only in solving technical problems

• Willingness to be based in Ipoh and to travel to customers

Advantageous, not required

• Previous sales, business development or key account management experience

• Exposure to power semiconductors or wide bandgap technologies such as SiC and GaN

• Experience with automotive, industrial, AI or communications customers

• Additional languages, particularly Mandarin, given our international customer base
