CNC PROGRAMMER

Addman Engineering • Glen Burnie, MD

10d • $40 - $57 • Onsite

About The Position

We're looking for a senior CNC programmer to plan and program work across our full machine shop — 2-3 axis mills, mill-turn/live-tooling lathes, and 3+2 indexed multiaxis mills — using Mastercam 2025. This is a hands-on programming role: you'll take parts from print to verified, production-ready NC code, and you'll be the person other programmers and machinists turn to when a setup gets complicated.

Requirements

• 5+ years of CNC programming experience, with hands-on Mastercam experience (2025 or recent prior versions).
• Demonstrated ability to program 2-3 axis mill work: pocketing, contouring, drilling/tapping, and multi-setup part planning.
• Demonstrated ability to program lathe/mill-turn work: OD/ID turning, grooving, threading, and live-tooling/C-axis operations; sub-spindle part-transfer experience a strong plus.
• Demonstrated ability to program 3+2 (positional/indexed) multiaxis work: plane/WCS strategy, work-offset planning across multiple orientations, and collision-aware setup verification.
• Working knowledge of G-code and post-processor structure, sufficient to read, troubleshoot, and hand-edit posted programs when needed.
• Solid understanding of feeds, speeds, and tooling selection for common shop materials (e.g., aluminum, stainless, and alloy steels).
• Ability to read engineering prints, including GD&T, and machinist-level shop math.

Nice To Haves

• Experience with a specific control platform used in-house (e.g., Fanuc, Siemens, or a Fanuc-style proprietary control) — specify per your shop.
• Experience training or mentoring junior programmers.
• Familiarity with CMM/inspection processes and how they relate back to programming and fixturing decisions.
• Continuous simultaneous 5-axis programming experience, beyond 3+2 positional work.

Responsibilities

• Program parts in Mastercam 2025 across mill (2-3 axis), lathe/mill-turn (including live tooling and sub-spindle transfer), and 3+2 positional multi-axis work, choosing the right process for each part rather than defaulting to one machine type.
• Read and interpret engineering prints, including GD&T callouts, and translate tolerance and finish requirements into realistic toolpath, tooling, and work holding decisions.
• Plan work holding and setup sequencing — single- and multi-setup mill parts, sub-spindle part transfer on the lathe, and multi-plane/indexed orientations on multi-axis work — to control cost, cycle time, and accumulated location error.
• Select tooling, feeds, and speeds appropriate to the material and operation, rather than relying on default values.
• Verify programs using solid/machine simulation (including fixture, holder, turret, and trunnion models where applicable) before release to the floor, to catch collisions and gouges ahead of the first live cut.
• Maintain and troubleshoot post processors and control definitions, and diagnose posted-code issues (incorrect rotary axis output, canned-cycle mismatches, offset errors) down to the root cause.
• Produce clear setup sheets and documentation — tool lists, work offset/plane assignments, and setup notes — that let another programmer or machinist run the job without reconstructing your reasoning from scratch.
• Support the shop floor during first-article runs and troubleshoot in-process issues (chatter, finish problems, thread fit, transfer marks, and similar) as they come up.
• Continuously look for opportunities to reduce cycle time and improve repeatability on running production jobs.
