Staff Machinist, CNC Programming (R4737)

Shield AI•Dallas, TX

1d•$38 - $58•Onsite

About The Position

Shield AI is seeking a highly experienced CNC Programmer / Machinist (Level 4) to play a critical role in the development of next-generation autonomous aerospace systems. This position operates at the intersection of engineering and manufacturing, enabling rapid hardware iteration by transforming complex digital designs into precision-machined components—often under aggressive timelines and evolving requirements. As part of a fast-paced prototype machining environment, you will work directly with design, manufacturing, and test engineers to bring early-stage concepts to life. Unlike traditional production roles, this position emphasizes adaptability, creativity, and speed. You will routinely machine first-of-their-kind parts, refine processes in real time, and contribute to design decisions through hands-on feedback and Design for Manufacturability (DFM) insights. Success in this role requires deep technical expertise in multi-axis CNC machining, along with the judgment to balance precision, efficiency, and urgency. You will be expected to independently manage complex jobs from programming through final inspection, while also navigating shifting priorities and incomplete data. The ability to problem-solve on the fly—whether addressing tolerance challenges, optimizing toolpaths, or developing quick-turn fixturing—is essential. This role also carries a leadership component. As a Level 4 machinist, you will help set the standard for technical excellence on the shop floor, mentor less experienced team members, and contribute to building scalable prototype machining processes that support rapid product development. Your work will directly impact the speed, quality, and success of Shield AI’s hardware programs.

Requirements

High school diploma or GED required; technical certification or associate degree in machining/CNC preferred
7–10+ years of CNC machining experience, including advanced programming and setup
Proven expertise in multi-axis machining (3-, 4-, and 5-axis)
Advanced proficiency with CAM software (e.g., Mastercam, Fusion 360, or equivalent)
Strong ability to read and interpret complex blueprints and GD&T
Demonstrated experience machining tight-tolerance, high-precision parts
Deep understanding of cutting tools, feeds/speeds, and material behavior (e.g., aluminum, steel, titanium)
Ability to create, edit, and optimize G-code programs
Extensive experience with setup, fixturing, and workholding design
Proven troubleshooting skills for machining issues, tool wear, and process inefficiencies
Experience with quality inspection tools (micrometers, calipers, etc.)
Strong knowledge of safety standards and manufacturing best practices
Ability to work independently with minimal supervision and manage multiple priorities

Nice To Haves

Associate’s or bachelor’s degree in Manufacturing Engineering, Mechanical Engineering, or related field
Experience in aerospace, defense, or medical device manufacturing (high-mix, tight-tolerance environments)
Familiarity with 5-axis simultaneous machining and advanced toolpath strategies
Experience with CAD modeling (SolidWorks, NX, etc.)
Knowledge of fixture and tooling design, including custom workholding solutions
Experience with post-processor editing or customization
Exposure to automation systems (robotics, pallet pools, lights-out machining)
Understanding of lean manufacturing, Six Sigma, or continuous improvement methodologies
Experience using ERP/MES systems (e.g., Palantir, JobBOSS, MaintainX )
Familiarity with AS9100, ISO 9001, or other quality management systems
Ability to collaborate in DFM activies, mentor junior team members, or provide technical guidance
Strong documentation skills for setup sheets, work instructions, and process standardization
Experience in machining exotic or difficult-to-machine materials (e.g., Inconel, titanium alloys, composites)

Responsibilities

Program, set up, and operate 3-, 4-, and 5-axis CNC machines for prototype and short-run parts
Develop and optimize CAM programs and G-code for speed, flexibility, and precision
Interpret CAD models, drawings, and GD&T to determine optimal machining strategies
Collaborate directly with design engineers to provide DFM (Design for Manufacturability) feedback
Execute rapid iteration cycles, including same-day or next-day part turnaround when required
Design and implement quick-turn fixturing and workholding solutions
Troubleshoot machining challenges in real time (tooling issues, deflection, tolerance stack-ups)
Select appropriate cutting tools, feeds/speeds, and strategies for a wide range of materials
Support first article inspection and ensure parts meet design intent and quality standards
Document setups and processes while maintaining flexibility for evolving designs
Mentor junior machinists and help elevate team capability
Maintain a strong focus on safety, quality, and mission urgency
