About Materiatek

Materiatek is a non-profit, independent organisation built around three pillars: Belgium's largest independent materials library dedicated to spatial design, a coworking space, and a vibrant events programme (Lab Lectures, Inspire Lectures, Spotlight Sessions). Based in a beautifully restored industrial space in Brussels, Materiatek is where architects, designers and makers explore, collaborate and connect to stay at the forefront of design innovation.

As a young and fast-growing organisation, we're looking for a commercially driven, hands-on Sales & Partnerships Manager to join our team and help shape one of the industry's most exciting initiatives.

The role

You will be responsible for the full commercial development of Materiatek, reporting directly to the founders. This is a role with real ownership: you will build and manage the partner and client base largely on your own initiative, with plenty of room for entrepreneurship.

Your primary responsibilities:

• Business development for the materials library: identify, approach and onboard new supplier partners to expand our curated collection of material samples.

• Sales for the coworking space: prospect and convert new coworking members and clients.

• Full ownership of the partner relationship lifecycle — from first contact and negotiation to onboarding and ongoing account management. A solid base of partners is already in place; you will be expected to grow it further.

• Comfortable with proactive prospecting and cold calling/outreach — this is a core part of the role, not an occasional task.

Secondary responsibilities:

• Promote the use of the materials library among architects and designers within the Brussels design community, driving awareness and engagement.





• Support other activities as needed, including events — as is typical in a start-up environment, flexibility and a hands-on attitude are expected beyond your core scope.

Who you are

• You have at least a first experience in a commercial/sales role (junior profiles welcome, as long as you've already had exposure to sales).

• You are result-oriented, self-motivated and comfortable working independently.

• You have a genuine affinity with design, architecture and materials.

• You are not afraid of cold calling and proactive prospecting.

• You are a strong team player — this is a small, tight-knit team where collaboration matters.

• You are trilingual, with fluency (at minimum) in French/English or Dutch/French.

• You thrive in an entrepreneurial environment and enjoy building things from the ground up.

What we offer

• A unique opportunity to work on one of Belgium's most innovative design projects, in a beautiful, inspiring workspace.

• A part-time position (3/5 TO 4/5 days/week), with versátil working arrangements, a minimum of 50% on-site presence at our Brussels office is expected.

• Real autonomy and ownership over your commercial scope, with significant room for initiative and entrepreneurship.

• A close-knit, collegial team and a dynamic, informal working culture.

• A competitive salary in line with experience, complemented by extralegal benefits in line with market practice.

• The chance to be part of the growth story of a young, purpose-driven non-profit at the intersection of design, sustainability and community.
