Join Visibuilt to help develop the next generation of biobased materials for urban infrastructure. We are looking for a hands-on materials engineer who can turn formulation ideas into testable, high-performing materials and move quickly from lab results to practical improvements.
Location
Søborg, Greater Copenhagen, Denmark (on-site)
Start
As soon as possible
Type
Full-time employment
Core focus
Developing new materials using visiBINDER with rubber, wood, and other aggregates
About Visibuilt
Visibuilt is building fossil-free alternatives for pavement materials. Our core technology, visiBINDER, is a 100% bio-based binder developed from mycelium and designed to reduce energy use and CO2 emissions in infrastructure materials. We are based at Alfa Laval Innovation House in Søborg, just outside Copenhagen.
The role
This role is driven by a concrete commercial need: to develop a durable, safe and sustainable surfacing material for hard and soft applications. You will work with Visibuilt’s binder together with different aggregate types ranging from stones and wood to rubber and plastic and other fillers, and you will be expected to run fast, practical development loops from formulation through testing and next-step decisions.
• This is a materials role rather than a biotech role. You will work closely with our biotech team, but your main contribution will be formulation, materials testing and product development.
• We are looking for someone who enjoys being close to the material, the data and the decisions – not someone who wants to stay at a purely conceptual level.
Responsibilities
• Design and run practical lab experiments to develop new surface formulations based on visiBINDER.
• Evaluate polymers, elastomers, additives, fillers and reinforcement concepts that can improve durability, water resistance, flexibility and mechanical performance.
• Build and refine formulations using various hard and soft material systems.
• Plan, run or coordinate relevant testing, including mechanical testing, durability testing, weathering and application-specific safety testing.
• Translate test results into clear formulation changes, follow-up experiments and decision points for the team.
• Document learnings in a structured way to enable fast and clear progress in the experiments.
• Support the path from lab concept to scalable industrial processing by keeping manufacturability and practical implementation in view.
Need-to-have requirements
• Degree in Materials Science, Materials Engineering, Polymer Engineering, Chemical Engineering or a closely related field.
• Minimum 3 years of hands-on industrial experience in material development – not only academic or theoretical research.
• Strong practical experience with polymers, elastomers, rubbers, wood-based fillers, composites or related material systems.
• Ability to work independently in a lab or R&D environment, from formulation through testing and iteration.
• Experience with mechanical testing, durability testing or performance validation in real-world material applications.
• A practical, structured and solution-oriented working style suited to a fast-moving company.
Nice to have
• Experience with soft surfaces, flooring, pavement, roofing membranes, or other outdoor material applications.
• Experience with recycled rubber, wood-based fillers, natural fibres or other circular material systems.
• Knowledge of standards or certification pathways relevant to outdoor safety surfaces.
What success looks like
• You identify promising formulations that combine safety, durability, weather resistance, and practical manufacturability.
• You create a fast development loop where each test leads to a clearer next move.
• You help Visibuilt move closer to a commercial surface that can meet relevant performance and safety standards.
What you can expect from Visibuilt
Visibuilt offers the chance to work on a visible climate-tech challenge in a small, ambitious team where your work can have direct technical and commercial impact.
- Mission-driven company building biobased alternatives for infrastructure materials
- On-site collaboration in Søborg, with access to production space, offices and an innovation environment at Alfa Laval Innovation House
- Flexible way of working, with benefits including pension, healthcare insurance, and 30 days of paid holiday each year.
Practical note
Because the need is urgent, candidates already based in Denmark, Southern Sweden or Northern Germany with valid work permits for Danmark will have an advantage in the process.
