We are looking for an experienced, detail-oriented, and self-motivated Senior CNC Machinist to join our fast-paced machine shop. In this role, you will own the machining process from print to finished part, working directly with our engineering team on complex, first-of-their-kind prototypes and short-run production. Beyond core machining execution, you will play a key role in shaping our shop culture by mentoring younger machinists, refining machining strategies, and driving continuous improvement in our shop processes. Key Responsibilities Machining & Prototyping Ownership Program, set up, and operate multi-axis CNC mills (3-axis and 5-axis) and lathes for high-precision, low-volume, and prototype parts. Interpret complex engineering prints, CAD models, and GD&T specifications. Develop custom tooling, workholding, and fixturing strategies for novel or difficult-to-machine components. Run first-article parts, perform in-process QA/inspection, and transition proven processes into short-run production. Collaborate directly with mechanical and electrical engineers to provide Design for Manufacturability (DFM) feedback and iterate on designs in real time. Mentorship & Shop Leadership Mentor, train, and guide entry-level machinists and apprentices on setup techniques, safety practices, print reading, and machining fundamentals. Perform code and setup reviews for junior team members to ensure process repeatability and prevent tooling crashes. Help cultivate a collaborative, growth-focused environment where learning and skill development are prioritized. Lead by example in maintaining high shop standards, tool organization, inventory management, and equipment maintenance. About Ansync Ansync is a product development company. Electrical, mechanical, firmware, and manufacturing engineering all live under one roof, which lets us take a product from a napkin sketch through prototype, verification testing, and into production without handing it off to anyone else. Our customers come to us with hard problems—medical devices, instrumentation, and industrial products that don't have an off-the-shelf answer. Our machine shop is central to how that works. It's where the parts our engineers design actually get made, measured, tested, broken, redesigned, and made again. When a design needs to change on a Tuesday, we cut new parts on a Tuesday. Who Should Apply You are a master of your craft: You have years of hands-on machining experience and thrive on the challenge of making parts that have never been made before. You want variety, not repetition: You are tired of push-button production environments and want a role where you tackle new geometries, materials, and design challenges every week.

You enjoy teaching:

You take pride in passing down your knowledge, helping younger machinists build their skills, and seeing your team succeed as a whole.

You are a collaborative problem-solver:

You enjoy sitting down with engineers to figure out how to turn an ambitious concept into a tangible, manufacturable part. Minimum Qualifications 5+ years of hands-on CNC machining experience, including setup, programming, and operation of multi-axis mills and lathes. Proven track record of mentoring, coaching, or training junior machinists, trade students, or apprentices. Advanced proficiency in CAM software (Fusion 360, Mastercam, or equivalent) and G-code manipulation. Strong ability to read and interpret complex engineering drawings, CAD models, and GD&T standards (ASME Y14.5). Experience with custom fixture design, workholding strategy, and tooling selection. Comfortable working in a fast-paced, changing environment with evolving priorities. Effective written and verbal communication skills. Preferred Qualifications 7+ years of experience in high-precision prototype machining or job-shop environments. Deep proficiency with Fusion 360 and its Manufacturing extension. Experience operating Haas and Fanuc controls, including 5-axis machines. Familiarity with CAD software (SolidWorks, Inventor, Fusion 360) for model preparation and fixture design.
