Process Engineer II (Drying and Crystallization)

Position Overview:

Solid Power is seeking a Process Engineer II to join our talented team of engineers and scientists working to revolutionize the battery industry through the development of next‐generation, all solid‐state rechargeable batteries. Solid Power is a public company with a dynamic, fast‐paced, and highly collaborative environment where innovation thrives. This role will play a key part in commissioning, qualifying, and sustaining the drying and crystallization unit operations on our electrolyte line as we introduce new process equipment. The preferred candidate will have hands-on process engineering experience with drying and high temperature solid-state crystallization processes, along with the ability to take a unit operation from new equipment through qualification and into stable production.

Job Duties:

• Own the process for the drying and crystallization unit operations of electrolyte production, including defining and maintaining process parameters, operating windows, and control strategies that consistently meet material specifications.
• Use process development data and engineering inputs to define the process windows and conditions to explore during equipment commissioning, validation and normal operations.
• Lead the process side of commissioning and validation for new drying and crystallization equipment, working closely with electrolyte systems engineering, production, and equipment engineering to confirm the process is capable and ready for production.
• Translate material specifications such as particle size distribution, morphology, residual solvent, and crystallinity into process parameters and in-process controls.
• Use SCADA and batch record data to monitor process performance, identify drift, and determine critical process parameters.
• Lead root cause analysis and corrective action for process issues affecting throughput, yield, quality, safety, and process stability.
• Apply statistical tools such as JMP or Minitab to evaluate process changes and confirm whether results are meaningfully different.
• Participate in and lead PFMEAs, process hazard analyses, and management of change for these unit operations, and implement layers of protection to keep the process safe.
• Develop and maintain SOPs and work instructions for equipment and process operations.
• Provide the process requirements that equipment engineering uses to specify new equipment with vendors, and support installation and start-up from the process side.
• Build strong working relationships with operators and the production team and support day-to-day operations on the line.
• Partner with process optimization engineering on continuous improvement projects for these unit operations.
• Assist EH&S in maintaining occupational safety on the manufacturing floor.
