Who we are
At CarbonX, we are solving one of the clean energy transition's biggest bottlenecks: replacing imported graphite in EV batteries with a local, scalable, high-performance carbon material. Our technology enables 6-minute ultra-fast charging and lower production emissions, dropping directly into existing commercial manufacturing lines without requiring cell makers to retool.
Born out of TU Delft, we’ve crossed the initial R&D threshold. We are now transitioning from technology development to industrial manufacturing and global scale—expanding our footprint across the Netherlands, Texas, China, and South Korea to supply Tier-1 automotive and battery partners.
If you're motivated by high-velocity execution, true hands-on ownership, and doing work that has a visible, measurable impact on global energy independence, this is where you can build something that scales.
The Role
As our Electrode Specialist, you will take direct responsibility for our electrode-making process in our Delft laboratory. This is a practical, bench-first role (80% practical lab execution & quality control, 20% data analysis, reporting & process improvement) that sits at the center of our commercial validation pipeline.
Because CarbonX materials physically behave differently from standard graphite during dispersion and calendering, you will play a crucial role in diagnosing processability, optimising slurry formulations, and ensuring defect-free electrode production.
Key Responsibilities
• Slurry Preparation & Electrode Manufacturing: Formulate, mix, coat, and calender slurries containing active materials, binders, and conductive additives strictly in line with experimental and customer protocols.
• Physical & Diagnostic Characterisation: Perform hands-on bench tests including rheology and viscosity profiling, slurry density, moisture, particle fineness analysis, adhesion and peel-strength testing (90°/180°), and Scanning Electron Microscopy (SEM).
• Processability Optimisation: Observe how novel carbon structures interact during mixing and calendering; identify physical bottlenecks to ensure process repeatability.
• Operational Troubleshooting & QC: Enforce strict quality control standards. Identify root causes of material or coating deviations and execute real-time operational problem-solving.
• Lab Equipment Ownership: Manage, calibrate, and maintain key equipment (different types of mixers, coating/calendering lines, diagnostic tools), manage routine calibration and preventative maintenance, and draft practical SOPs.
• EHS Rigor: Maintain a clean, organised, and safe laboratory environment, strictly following chemical handling and safety protocols.
Enough about us - what about you?
To really enjoy and excel in this role, we imagine you will have a background encompassing the following:
• Lab-First Mindset: You genuinely enjoy being hands-on at the lab bench (80%+ of your time) over desk-based research and take pride in precision execution.
• Practical Experience: 1–2+ years of practical, applied laboratory or industrial scale-up experience in electrode manufacturing (slurry preparation, coating, calendering) or adjacent liquid-coating/formulation industries.
• Educational Background: Bachelor's (BSc), HBO, or MBO in Materials Science, Chemistry, Chemical Engineering, or a related practical scientific discipline.
• Scale-Up & QC Mindset: Motivated by extreme accuracy, precision, and detail, but adaptable enough to troubleshoot operational lab issues calmly under customer deadlines.
• Fluent English: Professional working proficiency in spoken and written English.
Why Join Us?
• Real Industrial Impact: Your bench precision directly validates our novel carbon material, impacting customer sign-offs and multi-million-euro supply contracts.
• Culture & Leadership: Join a collaborative, supportive lab team led by Agnes Chojnacka where open feedback and safety are prioritised.
• Deep Tech Scale-Up Environment: Work directly with novel carbonic structures…
