Manufacturing Engineer

Rennscot MFG•Woburn, MA

41d•$75,000 - $150,000•Onsite

About The Position

The Manufacturing Engineer is a key role within our Engineering department, responsible for the full lifecycle of CNC programming and process development across 2, 3, 4, and 5+ axis turning and milling machines. This role owns its work — from tooling selection and fixture design through prove-out, operator training, and continuous improvement — and is expected to deliver production-ready results with a high degree of accuracy and accountability.

Requirements

Meaningful time on the shop floor running and programming multi-axis CNC machines — owning setups, solving problems, and producing parts that meet tight tolerances.
Ability to read and interpret technical drawings and GD&T callouts and translate them directly into a machining strategy.
Ability to build a CNC program from scratch in Fusion 360, Hypermill, or a comparable CAM platform and understand the reasoning behind toolpath choices.
Ability to select tooling, set speeds and feeds, and design a workholding approach appropriate for the part geometry and material.
Ability to prove out own programs, catch own errors, and reduce run time without sacrificing quality.
Ability to troubleshoot a dimensional miss, trace it back to root cause, and fix it.
Proficiency using calipers, micrometers, indicators, and other metrology tools accurately and routinely.
Confidence operating Haas and/or Heidenhain controllers.
Ability to document a setup clearly enough that an operator can run it without direct supervision.
Ability to manage several active jobs at once without losing track of quality or delivery commitments.
Must be a US citizen, lawful permanent resident of the US, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the US Department of State.

Nice To Haves

Familiarity with controller-level troubleshooting.

Responsibilities

Develop manufacturing processes including tooling and raw material selection, fixture design, and CNC programming in Fusion 360 and/or Hypermill across 2, 3, 4, and 5+ axis turning and milling machines.
Write CNC programs including advanced techniques such as macro programming, Q variable programming, and in-process probing.
Conduct post-program prove-out for error checking and run time reduction.
Identify root causes of dimensional errors, rework, and inefficiency; lead and implement corrective actions.
Design quality, safety, and dimensional integrity controls into new technical work.
Produce and maintain setup documentation in ProShop ERP including tooling lists, work-holding instructions, program references, and run notes.
Manage multiple concurrent components and projects to meet quality and lead-time requirements.
Troubleshoot geometric errors in multi-axis machinery to resolve dimensional issues.
Train machine operators on developed processes — covering machine operation, tooling use, and the reasoning behind each step.
Mentor CNC programmers and operators; share best practices and support team development.
Support process standardization and departmental improvement efforts.
Support other projects and assignments as needed.
