Manufacturing Engineer at Fathom Mfg – Round Rock, Texas

Position Summary

The Manufacturing Engineer is responsible for developing, optimizing, and sustaining efficient manufacturing processes within a CNC machine shop environment. This role serves as the technical bridge between engineering, CNC programming, quality, and production, ensuring parts are manufactured safely, on time, at the highest quality, and at optimal cost. The Manufacturing Engineer drives continuous improvement in machining processes, work instructions, tooling, fixturing, and workflow.

Key Responsibilities

Process Development & Optimization

• Develop and document manufacturing processes for CNC‑machined components, including routing, operation sequencing, and setup strategies.
• Optimize cycle times, setup times, and material flow to improve throughput and on‑time delivery.
• Lead root cause analysis and corrective actions for scrap, rework, quality escapes, and process inefficiencies.
• Apply Lean Manufacturing, 5S, and continuous improvement methodologies.

CNC & Production Support

• Collaborate closely with CNC Programmers to define machining strategies, tooling selection, and workholding concepts.
• Support new part introduction (NPI), including feasibility reviews, DFM feedback, and first‑article readiness.
• Provide shop‑floor support during setups, prove‑outs, and production issues.
• Assist with multi‑axis machining strategies and complex part manufacturing.

Tooling, Fixtures & Documentation

• Design or specify fixtures, gauges, and tooling as required to support efficient and repeatable machining.
• Maintain and improve standardized work instructions, setup sheets, and process documentation.
• Support tool crib organization, tool standardization, and offline setup initiatives.

Quality & Inspection

• Work with Quality Engineering and CMM programming to define inspection strategies and critical characteristics.
• Ensure processes meet drawing requirements, GD&T, and customer quality standards.
• Support first article inspections (FAI) and ongoing process capability improvements.

Cross‑Functional Collaboration

• Partner with Production, Quality, Planning, and Operations to resolve constraints and bottlenecks.
• Support scheduling and capacity initiatives by providing accurate process data (cycle times, setups, routings).
• Participate in customer and internal technical reviews as needed.

Required Qualifications

• Bachelor’s degree in Manufacturing Engineering, Mechanical Engineering, or equivalent experience.
• 3–7+ years of experience in a CNC machining or precision manufacturing environment.
• Strong understanding of CNC machining processes (milling, turning, multi‑axis preferred).
• Experience with GD&T and interpretation of engineering drawings.
• Hands‑on experience with tooling, fixturing, and machining process optimization.
• Proven ability to troubleshoot machining and production issues on the shop floor.

Preferred Qualifications

• Experience in high‑mix, low‑to‑medium volume CNC machine shops.
• Familiarity with CAM systems (e.g., Mastercam) and CNC programming concepts.
• Experience with CMM inspection processes and SPC.
• Knowledge of ERP / MES systems used in manufacturing operations.
• Background in aerospace, medical, semiconductor, or other precision industries.

Key Competencies

• Strong problem‑solving and analytical skills
• Ability to work cross‑functionally and communicate effectively with shop personnel
• Detail‑oriented with a focus on process discipline and documentation
• Bias for action and continuous improvement
• Comfortable working in a fast‑paced manufacturing environment

Physical & Work Environment Requirements

• Ability to work on the shop floor, including standing, walking, and observing machine operations.
• Occasional lifting of tooling or fixtures (within safety guidelines).
• Exposure to typical machine shop environments (noise, coolant, metal chips, PPE required).
