Job description

Beehive Industries is dedicated to Powering American Defense by revolutionizing the design, development, and delivery of jet propulsion systems to support the warfighter. Through the integration of additive manufacturing, the company aims to meet the growing and urgent needs for unmanned aerial defense by dramatically improving a jet engine’s speed to market, fuel efficiency, and cost.

Founded in 2020, the company is headquartered in Centennial, Colorado, with additional facilities in Knoxville, Tennessee, Loveland Ohio, and Mount Vernon, Ohio. Beehive is committed to grow and advance the defense industrial base while manufacturing exclusively in the USA. This role will be located at our Knoxville, Tennessee facility.

Role Overview

We are seeking an experienced Manufacturing Engineer with a strong additive manufacturing background to support production operations through process development, industrialization, continuous improvement, and technical problem solving. The ideal candidate will have hands-on experience with Laser Powder Bed Fusion (LPBF) and/or Metal Binder Jetting (MBJ), including build preparation, process parameter control, powder handling, post-processing, equipment troubleshooting, and production scale-up within a high-precision manufacturing environment. Experience in aerospace manufacturing is strongly preferred. This role will work closely with production, quality, supply chain, maintenance, and Lifecycle Manufacturing Engineering to ensure safe, capable, repeatable, and scalable additive manufacturing processes.

What You’ll Do

• Own manufacturing process execution, capability, and production readiness for assigned manufacturing areas, processes, products, or components
• Translate product manufacturing strategy, process intent, and technical requirements provided by Lifecycle Manufacturing Engineering into capable, repeatable, and scalable production processes
• Develop, implement, qualify, and continuously improve manufacturing processes across additive manufacturing, machining, assembly, inspection, post-processing, or related advanced manufacturing operations
• Lead process implementation and production-readiness activities from NPI transfer through sustained production and rate ramp
• Partner with Lifecycle Manufacturing Engineering to ensure manufacturing requirements, product characteristics, process intent, and technical risks are properly translated into site-level manufacturing controls
• Lead development and maintenance of manufacturing Process Flow Diagrams, PFMEAs, Control Plans, work instructions, standard work, routings, and other production process documentation
• Ensure critical and key product characteristics are appropriately created, controlled, measured, and verified within the manufacturing process
• Lead manufacturing process qualification, capability studies, and production validation activities prior to release into sustained production
• Provide direct technical support to Operations for manufacturing issues affecting safety, quality, delivery, cost, yield, or throughput
• Own implementation of engineering and configuration changes at the manufacturing site, including updates to tooling, programming, routings, work instructions, inspection requirements, qualification activities, and operator training
• Monitor and improve site manufacturing performance including first-pass yield, scrap, rework, cycle time, takt attainment, throughput, process capability, and equipment effectiveness
• Support low-rate initial production and production ramp activities while ensuring manufacturing processes transition into stable, controlled, and sustainable production systems
• Serve as the site manufacturing engineering representative on Manufacturing Program Teams, production-readiness reviews, and other cross-functional manufacturing forums
• Support continuous improvement initiatives focused on safety, quality, delivery, cost, process capability, throughput, and manufacturing scalability
