Battery Engineer​/Technician, Electrode Specialist

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.

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.

• 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.

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.

• Real Industrial Impact:
  Your bench precision directly validates our novel carbon material, impacting customer sign‑offs and multi‑million‑euro supply contracts.
• Culture &…
