What we are looking for

Are you a highly-organised and safety-minded professional who takes pride in keeping a lab running like clockwork? Do you enjoy the mix of hands-on analytical work and the discipline of maintaining equipment, protocols, and a safe working environment? Are you someone who can juggle multiple priorities, support a fast-moving R&D team, and consistently deliver reliable, high-quality data?

If so, we would love to hear from you. Join us in scaling a groundbreaking technology that is transforming the future of textile recycling.

Your mission at Renasens

You see a lab not just as a workspace, but as a system that needs to run safely, cleanly, and reliably for the science to happen. You will take ownership of day-to-day lab operations, safety, equipment, and organization, while also rolling up your sleeves to run and support the analyses that drive our R&D decisions, from dye removal characterization to fiber mechanical testing.

• Own lab safety end-to-end: ensure protocols, PPE use, chemical handling, storage, and waste disposal meet regulatory and internal standards
• Maintain, calibrate, and troubleshoot lab equipment including analytical and mechanical instruments, coordinating servicing and repairs as needed
• Assist the R&D team in running analyses supporting treatment & dye removal development, including TGA, spectrophotometry and chromatography
• Run and support mechanical characterization of fibers, including tensile strength, bursting strength, fiber length and spinnability
• Manage lab consumables, inventory, and equipment logs to keep experiments running without interruption
• Develop and maintain SOPs for equipment use, safety procedures, and testing protocols
• Keep the lab organized, clean, and audit-ready at all times
• Work closely with technicians and process engineers, flagging equipment or safety issues before they become blockers

What you bring

BSc or MSc in chemistry, materials science, textile engineering, or a related field. Industry or lab-operations experience is a strong plus.

Hands-on experience with analytical lab equipment (TGA, spectrophotometry, XRD, or similar) and mechanical testing equipment (tensile strength, bursting strength & fiber length testers)

Ownership of lab safety practices, chemical handling, and regulatory requirements

Who you are

Safety-first: you don't cut corners, and you make sure others don't either

Reliable and independent: you take ownership of the lab's day-to-day and deliver without needing close supervision

Detail-oriented: you notice when something's slightly off with equipment or data before it becomes a bigger problem

Team over ego: you're there to support the wider R&D effort, not just your own tasks

Comfortable switching between hands-on lab work, equipment troubleshooting, and administrative upkeep (logs, SOPs, inventory)

Thrive in a fast-paced environment, energized by ambitious timelines and a growing lab

Great to have, but not required

Experience with dye-fiber chemistry or textile recycling processes

Experience with mechanical testing standards for textiles/fibers

Prior experience setting up or managing a lab from an early stage startup

How we work at Renasens

Onsite & hands-on: Our pilot plant is in Borås and this role is based where the work happens, close to the lab and the pilot, not behind a laptop. Expect to spend most of your time on site, keeping the lab running and supporting the team's experiments.

Small team, high ownership: We are around 10 people. You will own lab operations end-to-end and work directly with the R&D team, industrial engineer and CEO. No layers, no committees.

Pace matters: We have pilot reception milestones in 2026 and customer commitments behind them. We move fast, decide with the data we have, and iterate.

Compensation & benefits

• Wellness allowance
• Pension scheme
• 30 days vacation
• Rapid career growth
