Core Dux is a global leader in high precision engineered artery systems and flexible fluid and gas assemblies for the most demanding industries, including semiconductor manufacturing, aerospace, medical technology, and new energy. With more than a century of engineering excellence and a rapidly expanding footprint in semiconductors, Core Dux is investing significantly in the growth of its semiconductor business in France.

To support this momentum, we are looking for a Key Account Director Semiconductor
. This is a senior business and key account management role for someone who wants more than managing accounts alone. It is an opportunity to help build a business, strengthen long term customer partnerships, and create a platform for continued growth within Core Dux.

Relocation to France is essential and fully supported. This role is intended for someone who sees an international move as a strategic career step and wants to build a long term future within an ambitious and growing organization.

Core Dux works with leading semiconductor customers where expectations around reliability, commercial discipline, and delivery performance are high. As Key Account Director, you take ownership of strategic accounts in a market that is growing rapidly and becoming increasingly important to Core Dux.

You operate close to the customer and close to the business. You are accountable for protecting and growing revenue, managing commercial agreements, and ensuring that customer commitments are realistic and executable. This role offers a compelling combination of commercial ownership, international exposure, and long term growth potential.

You manage and grow a portfolio of strategic semiconductor customers and act as the primary commercial interface between customer and Core Dux.

• Build and maintain trusted relationships at senior customer level
• Own pricing, margins, and key commercial agreements
• Identify and develop growth opportunities within existing accounts
• Coordinate internally to ensure customer requirements are clearly understood and delivered
• Anticipate commercial and delivery risks and address them proactively

This is a hands on, commercially focused role with direct impact on business results.

This role is a key building block in Core Dux’s long term semiconductor strategy. While it is a senior commercial position from day one, the scope and impact can grow significantly over time.

Depending on performance and ambition, growth can take place through:

• Expanded responsibility within France, including a broader customer portfolio or increased commercial scope
• International growth within Core Dux, stepping into wider commercial or business roles at other Core Dux locations

Core Dux actively supports internal mobility and invests in professionals who combine strong commercial performance with long term commitment.

You bring:

• Five to ten years of experience in the semiconductor industry
• Strong experience in key account management or senior commercial roles in complex engineered environments
• A bachelor’s or master’s degree in engineering, technology, business, or a related field
• A sharp commercial mindset with comfort around pricing, margins, and contracts
• Experience working in project driven or matrix organizations
• Fluency in English
