Slot-Die Coating Engineer

Role details

A lithium-metal company building pouch cells aimed at 600–800 Wh/kg, and that casts their own thick cathodes on a slot-die roll-to-roll coater in Tallahassee is looking for someone to

own the die. Someone capable of

setting up the coater, run it, diagnose the defects, and you write it all down the same day. You'll work under the direction of our Principal Engineer (30+ years in cells). You'll do the work, not direct it.

What you'll be responsible for

• Set up and run the slot-die head

on our benchtop, single-furnace roll-to-roll coater with a slot-die attachment — nothing fancy. Die assembly, shim and gap, alignment, pump and feed, flow-rate-to-thickness math, line speed, drying.

• Run our twice-weekly casts start to finish, on your own.

Slurry mixing is handled by our slurry technician; you own everything from the die onward — setup, cast, dry, and the quality of the tape that comes off the line.

• Dial in the coating window

for thick, high-loading cathodes (30+ mg/cm² class) cast from high-solids slurries with our polymer binder — bead stability, edge control, cross-web uniformity — and eliminate

defects at source

: streaks, bubbles, agglomerates, edge beads. Find the cause, fix it, prove it on the next cast.

• Document every run in Teams the same day

— parameters, photos, results, what you'd change next.

Experience:

• Hands-on slot-die coating where you owned the die.

You can talk fluently about the coating window, the bead, shim and gap, and exactly what you did the day the coat streaked.

• Battery electrode slot-die experience preferred.

Deep slot-die hands from another roll-to-roll industry — films, tapes, membranes, photovoltaics, photographic or optical coatings — are welcome.

• You run machines.

You're at home in a small lab where you set up, cast, clean the die, and fix the pump yourself.

• Able to relocate to Tallahassee, Florida — help with relocation, and Florida has no state income tax.
• Calendering to a density target; slitting, notching, and punching of coated electrode; pilot-line or scale-up experience; comfort in a dry room or glovebox.
• We need more than doctor blade or comma bar coating experience.

And you'll need to be able to spend a paid on-site cast day on our line in Tallahassee, with

an offer coming within 48 hours

of a good cast day.

Stock options on a three-year vest, plus a milestone bonus tied to cell and pilot-line goals. Signing bonus and relocation assistance. Plus 100% company-paid medical, dental, and vision for you and your family; 17 days of PTO. A small team where the CEO is in the lab and your cast is the company's cathode.
