Principal Scale-Up Engineer

Role overview

The Principal Scale-Up Engineer will be responsible for providing technical leadership in scaling up chemical processes from lab-scale to full-scale manufacturing. This is a hands-on opportunity to help design build and lead a world-class engineering function at Ereztechs new flagship facility. The successful candidate will oversee the design and execution of manufacturing processes contribute to production optimization and ensure consistency in quality and throughput. They will play a central role in building and managing the Engineering staff training plant operators and driving a culture of operational excellence. This role is ideal for a broadly experienced chemical process engineer who thrives in a dynamic environment and brings strong time management task organization and execution focus.

The position involves working with volatile air- and moisture-sensitive and pyrophoric
compounds where tight control over purity stability and reproducibility is essential across all stages of scale-up and manufacturing.

This role reports to the CEO of the company.

Key deliverables for this role

• Lead tech transfer from R&D to manufacturing for new organometallic and inorganic precursors

• Design scale and optimize production processes for purity yield and consistency

• Oversee equipment selection P&ID and reactor design for batch/semi-continuous systems

• Collaborate with QA/QC on analytical validation of trace-level specs (moisture halides metals)

• Identify and mitigate failure modes in air/moisture-sensitive or thermally unstable compounds

• Drive root cause analysis and CAPA for deviations contamination and yield loss

• Support SPC/SQC implementation and process control for HVM readiness

• Ensure EHS compliance in hazardous chemistries (e.g. Grignards metal hydrides)

• Lead continuous improvement using Lean and Six Sigma tools

Traits of a strong candidate
