About us

CarbonX is an advanced materials company based in Delft, developing a revolutionary carbon material for the next generation of batteries. A fast-growing spin-off from TU Delft, we now operate at commercial scale with global clients, international partners, and a growing team of innovators. Our labs and offices are located in Delft, and our work contributes to building a more resilient and sustainable battery supply chain.

What you’ll do

As a Battery Technician/Engineer, you’ll play a key role in making sure our new materials work just as they should. You’ll work alongside other engineers and technicians to help improve our materials and processes.

Based on your expertise you will be assigned to one of these two functions below:

Option 1 – Slurry / Electrode Focus

In this function, you will work on:

• Slurry mixing, rheology, finess & solid content measurements

• Electrode coating & calendering

• Electrode quality control & characterization

Option 2 – Cell Assembly Focus

In this function, you will work on:

• Cell assembly (coin / SLP)

• Battery testing & data processing

• Post-mortem analysis

Regardless of the focus, your main responsibilities will also include:

• Maintain the lab: Keep our equipment running smoothly and safely – and make sure we follow the right procedures.

• Quality control: make sure that results are precise and accurate, write and/or amend procedures.

• Conduct detailed observations & making comprehensive reports: ensure clarity, maintenance, and continuous performance improvement.

• Collaborate with the team: Work closely with engineers and technicians to solve problems and improve processes.

• Adhere to all safety guidelines, protocols, and regulations to ensure a safe working environment for yourself and your colleagues.
