Join Visibuilt to help develop the next generation of biobased materials for urban infrastructure. We are looking for a hands-on laboratory technician who can manage the testing or prototypes and move quickly from early test-setup to efficient material data collection to guide our experiments at Visibuilt.

Location: Søborg, Greater Copenhagen (on-site)

Start: As soon as possible

Type: Full-time employment

Core focus: Laboratory work focused on material testing, data collection, and equipment maintenance/calibration.

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

The role focuses on execution of material testing and data analysis for development and validation of pavement-related materials, including mycelium-based composites.

Main responsibilities

• Perform laboratory testing according to established standards and internal protocols

• Execute mechanical tests including:

• Indirect Tensile Strength (ITS)

• 3-point bending (flexural strength)

• Compressive and general strength testing

• Conduct accelerated aging tests such as wet–dry cycles, freeze–thaw, and applied loading

• Prepare, condition, and handle material samples prior to testing

• Collect, process, and analyze test data, ensuring consistency and traceability

• Document results in the electronic lab notebook and contribute to reporting

• Support development and validation of new material formulations through systematic testing

• Be the custodian of the laboratory equipment: ensure that maintenance and calibration is carried out, and generally make sure that the equipment is keep in good order.

Preferable Profile

• Hands-on experience with laboratory testing of materials

• Familiarity with standard testing protocols (preferably for asphalt, concrete, or similar composite materials), experience with pavement-related standards and testing methods

• Ability to work independently with structured experimental workflows

• Strong attention to detail and data quality

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.
