About The Position

Fathom Manufacturing is seeking a hands-on technical and people leader to turn awarded aerospace and defense programs into production-ready manufacturing processes. The role leads Manufacturing Engineers and partners with Operations, Quality, CNC Programming, Toolmaking, Program Management, and Pre-Sales Engineering.

The position owns manufacturing engineering execution for new programs, from technical handoff and process development through readiness reviews, first-piece builds, and production ramp-up. It develops and validates CNC manufacturing processes and supports program prove-outs, process stability, manufacturability improvements, engineering changes, and structured problem-solving. The role also defines tooling, fixture, gauge, equipment, and capital requirements, and uses production data and lessons learned to improve future programs and compare actual performance with quoted assumptions.

The successful candidate brings CNC expertise, leadership capability, and a continuous-improvement mindset to help move complex aerospace and defense programs from award to sustained production. Ability to travel is required.

Requirements

• Bachelor's degree in manufacturing engineering, mechanical engineering, or a related field, or equivalent precision-manufacturing experience.
• Experience supporting aerospace and defense manufacturing, new program introduction, production readiness, and controlled documentation.
• Deep hands-on CNC manufacturing knowledge, including machining methods, materials, GD&T, process planning, tooling, workholding, and inspection.
• Experience developing manufacturing processes, solving complex production issues, and improving quality, throughput, and cost.
• Working proficiency with CAD/CAM, CNC programming concepts, process documentation, and manufacturing data analysis.
• Proven success leading engineers, managing competing priorities, and driving technical execution and accountability.
• Strong operational and financial judgment, including cycle-time analysis, manufacturing cost evaluation, capital support, and quote-to-actual review.
• Ability to travel.

Responsibilities

• Lead, coach, and develop Manufacturing Engineers while setting clear priorities and accountability.
• Own manufacturing engineering execution for new programs, including technical handoff, process development, readiness reviews, first-piece builds, and production ramp-up.
• Develop and validate CNC manufacturing processes, including routings, machining methods, tooling, workholding, setups, inspection checkpoints, and controlled documentation.
• Partner with CNC Programming and Operations to prove out programs, improve process stability, and establish repeatable setup and cycle-time expectations.
• Define tooling, fixture, gauge, equipment, and capital requirements; support implementation and confirm expected results.
• Lead manufacturability improvements, engineering change execution, and structured problem-solving for quality and production issues.
• Improve quality, throughput, setup time, cycle time, tool life, material utilization, and manufacturing cost performance.
• Compare actual performance with quoted assumptions and apply production data and lessons learned to future programs.

Benefits

• Medical, dental, and vision coverage.
• Life insurance.
• Short-term and long-term disability insurance.
• Paid time off.
• Floating holidays.
• Volunteer time off.
• Sick time off, depending on state of employment.
• 401k plan.
• Discounts on products and services.
