Job Description

Overview

Coronal Technologies is seeking a Senior Mechanical Engineer to design, develop, and deploy mechanical systems for their manufacturing equipment and factory. This role involves hands-on work in a fast-paced environment focused on advanced spacecraft components using plasma arc additive manufacturing.

Responsibilities

  • Lead the mechanical design and development of factory equipment, machine subsystems, robotic end effectors, tooling, fixtures, and automation hardware.
  • Own mechanical systems from initial requirements and concept development through detailed design, fabrication, assembly, commissioning, and production use.
  • Design robust end-of-arm tooling and process hardware integrating mechanisms, actuators, sensors, pneumatics, electrical components, cooling, cable routing, and process utilities.
  • Perform structural, thermal, tolerance, fatigue, and mechanical analysis as appropriate to drive design decisions.
  • Develop engineering drawings, GD&T, material specifications, assembly documentation, and manufacturing packages.
  • Design equipment for reliability, maintainability, serviceability, repeatability, and rapid iteration in a production environment.
  • Work directly with machinists, technicians, vendors, and internal manufacturing teams to fabricate, assemble, debug, and improve equipment.
  • Develop test and validation plans for mechanical systems and establish clear acceptance criteria before deployment to production.
  • Lead root-cause investigations of mechanical failures and implement durable corrective actions.
  • Define and improve mechanical engineering standards, component selection practices, design-review processes, and documentation.
  • Mentor junior engineers and serve as a technical authority for mechanical design, machine architecture, and producibility.
  • Collaborate with process and manufacturing teams on equipment for plasma-arc additive manufacturing, CNC, welding, inspection, material handling, and related production processes.
  • Support equipment safety, configuration control, and QMS requirements consistent with an AS9100 manufacturing environment.

Requirements

  • B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, Robotics, Mechatronics, or a related field.
  • 8+ years of experience designing mechanical systems, industrial equipment, robotics, automation, or other complex hardware.
  • Demonstrated experience taking mechanical systems from concept through fabrication, commissioning, and sustained operation.
  • Strong proficiency in 3D CAD; onshape/SolidWorks preferred.
  • Strong understanding of machine design fundamentals including mechanisms, bearings, linear motion, actuators, fasteners, structural design, and tolerance analysis.
  • Experience creating production-quality engineering drawings and applying GD&T.
  • Experience designing systems that integrate mechanical components with sensors, motors, pneumatics, electrical hardware, or controls.
  • Strong practical understanding of manufacturing processes including machining, sheet metal, welding, fabrication, and assembly.
  • Ability and willingness to work hands-on with hardware during assembly, commissioning, troubleshooting, and production.
  • Strong technical judgment and ability to drive ambiguous engineering problems with limited oversight.
