Vacatures in Bijvanck

Location: Antwerp/Amsterdam (Hybrid)
Experience: 3-5 years in UX, industrial design, human factors, or related fields

As a User Experience Designer at Loop, you define how users physically interact with our products. You translate human needs into ergonomic, intuitive, and high-performing product experiences—from first touch to long-term use.

As a User Experience Designer at Loop, you will focus on shaping the physical interaction and ergonomics of our existing and new sensewear products. You will translate user needs into tangible design inputs, ensuring our products are intuitive, comfortable, and perform seamlessly in real-world use.

You research, design and validate physical user experiences aligned with product direction, user needs, and technical constraints. You translate insights into clear ergonomic and interaction principles and ensure they are carried through from early concept to mass production.

You bring structure to hardware UX by balancing comfort, usability, performance, look &feel and manufacturability. Trade-offs are translated into clear recommendations that support confident product decisions.

This role is ideal for someone who is passionate about human factors, physical product interaction, and iterative testing, and who wants to grow their expertise in hardware UX within a fast-scaling environment.

What you’ll do

Be the user’s voice

• Research user contexts so you understand the user profile 100% and can represent and defend their voice throughout product development.

• Closely collaborate with the product manager to co-create the intended value proposition that resonates with end users and differentiates from competitor’s user experiences.

Design physical user experiences

• Translate user needs into ergonomic and interaction design principles (fit, comfort, tactility, ease of installation)

• Contribute to product concepts through sketches, mockups, and iterative prototypes (3D prints, foam models)

Run and support hardware UX validation

• Plan and execute usability testing (fit, wearability, ease of use)

• Synthesize insights into clear design recommendations

Collaborate across product development

• Partner with Industrial Design and Engineering to ensure UX intent is maintained through DFM and production

• Participate in design reviews and support trade-offs between usability, performance, and manufacturability

You won’t

• Treat UX as purely digital or disconnected from physical product interaction

• Ignore constraints like acoustics, materials, or manufacturing realities

• Run tests without translating insights into actionable design improvements

• Stay in concept mode without validating in real-world use

You are deeply curious about how people interact with physical products, and you understand how small details can significantly impact comfort and usability. You contribute to products that demonstrate high comfort, intuitive use, and strong user satisfaction.

You combine hands-on experimentation with structured thinking, allowing you to explore ideas while staying grounded in real-world application.

You move confidently between prototyping and validation, knowing when to explore broadly and when to refine towards a clear direction. You communicate insights in a way that brings clarity and helps teams make better product decisions. Throughout the development process, you collaborate effectively across functions, consistently representing the user perspective and ensuring it remains central to the final product.

• 3-5 years of experience in UX, Industrial Design, Human Factors, or related field

• Strong understanding of ergonomics and physical interaction design

• Experience with prototyping methods (3D printing, mockups, iterative testing)

• Structured, test-and-learn mindset

• Ability to clearly communicate design rationale and insights

• Experience working in cross-functional product development teams

Nice to have

• Experience with wearable or body-adjacent products

• Familiarity with DFM, materials, and manufacturing constraints

• Exposure to usability testing frameworks for physical products

• See UX as purely digital rather than physical and experiential

• Avoid hands‑on prototyping and validation

• Struggle to balance user needs with technical constraints

• Have difficulty collaborating in cross‑functional product teams

• Need a clearly scoped and outlined brief

Good. This role is about turning human insight into real‑world product experiences. At Loop, UX lives in the physical details—fit, feel, and performance. If you’re ready to shape how products are experienced at scale, we’d love to hear from you.
