Manufacturing Engineer, Mechanical Assembly

Castelion Corporation•Torrance, CA

45d

About The Position

Castelion is seeking a highly skilled Manufacturing Engineer to develop, validate, and stand up the processes and tooling that turn mechanical assembly designs — actuators, mechanisms, and structural sub-assemblies — into repeatable, high-rate production. You will spend as much time on the floor as at your desk: designing fixtures, releasing work instructions, training operators, and driving process validation from first article through full-rate production. The ideal candidate is comfortable owning a process end-to-end, from concept through PFMEA, qualification, and hands-on troubleshooting on the line.

Requirements

Bachelor's degree in mechanical engineering, manufacturing engineering, or aerospace engineering
3+ years of experience developing or validating manufacturing processes in a production, manufacturing, or experimental environment

Nice To Haves

Hands-on tooling and fixture design experience, from concept through fabrication and qualification
Experience training or supervising production operators
Strong understanding of the APQP framework, specifically Control Plans, DFMEA, PFMEA, and managing Significant/Critical Characteristics
Previous involvement in a high-speed or high-output production environment, with hands-on experience on a production line
Experience with automation, robotics, and flexible manufacturing systems
Comfortable using hand tools, power tools, and fabrication equipment
Familiarity with Atlassian tools such as Confluence and JIRA
Excellent communication skills, both written and oral, along with effective teamwork abilities
Ability to acclimate to frequently changing assignments and a fast-paced working environment

Responsibilities

Develop, validate, and release manufacturing processes, work instructions, and process specifications for mechanical assembly operations
Design, procure, and qualify production tooling, fixtures, and manufacturing aids required for in-house production
Lead process validation activities — first article inspections, process capability studies, and PFMEA — to qualify new processes for production
Train and certify operators on new and revised processes, owning the process side of workforce ramp-up
Establish process controls, manufacturing standards, and inspection requirements to ensure consistent product quality
Partner with design engineering to provide DFM feedback and resolve build issues surfaced during production
Own real-time troubleshooting on the assembly floor, driving containment and root-cause corrective action for quality, yield, and throughput issues
Support the transition of processes from engineering development builds into documented, repeatable production, including workstation design and line layout
Work cross-functionally with design, quality, supply chain, procurement, and program management to meet performance, schedule, and cost objectives
