• 20+ years of progressive engineering experience in mechanical design, automation equipment, industrial machinery, or related fields. 
• Minimum 8+ years leading complex engineering programs or senior-level technical teams. 
• Proven experience taking products from concept through commercialization. 
• Experience in agricultural equipment, biotech equipment, medical devices, packaging automation, or industrial systems strongly preferred. 
• Experience in regulated, high-reliability, or harsh operating environments is a plus.

Working Conditions: 

Work is performed inside a flex space building consisting of offices, open desk space, laboratory, machine shop, and a manufacturing floor. Level of noise is usually quiet in the office environment and temperature controlled. Noise levels are elevated in the warehouse space where temperatures can vary depending on the outside elements and weather. Travel may be required, including up to 2-8 trips per year to visit suppliers, attend conferences, meetings (customer, investor, and business) and customer sites (hatcheries).
