Rennscot, an innovative manufacturing company, is seeking a highly skilled CNC Programmer & Machinist to join our team. This role is critical in developing and optimizing machining processes for complex, high-precision components in industries such as aerospace, defense, and space technologies. The ideal candidate will have extensive experience in multi-axis CNC programming, with a strong preference for expertise in Open Mind hyperMILL. This position requires a hands-on engineer who can develop robust, automated machining processes, oversee first article prove-outs, and ensure reliable, repeatable production. Candidates should be comfortable working with advanced probing routines, interpreting CMM data, and making process adjustments to improve quality and efficiency.
Description
Responsibilities
- Develop, optimize, and prove out multi-axis CNC machining processes for complex parts.
- Program CNC machines usingOpen Mind hyperMILL(experience with Fusion 360, ESPRIT, or Siemens NX is a plus).
- Design and fabricate custom workholding solutions, including fixtures for machining and inspection (e.g., CMM fixturing).
- Conduct first article prove-outs, verify setups, and refine programs for efficiency and reliability.
- Develop lights-out machining strategies, implementing automation to maximize unattended run time.
- Utilize advanced probing techniques to align components, particularly additive-manufactured parts, castings, and forgings.
- Interpret CMM inspection results, identify potential risks, and adjust machining strategies to ensure dimensional accuracy.
- Collaborate with the quality team to troubleshoot machining and inspection challenges.
- Create detailed setup documentation within ProShop ERP to support repeatable production.
- Provide guidance to entry-level programmers and operators when needed.
- Identify and implement continuous improvement initiatives to optimize processes, tooling, and cycle times.
Required Skills & Qualifications
- 6+ years of CNC programming experience, with an emphasis on multi-axis milling and mill-turn processes.
- Expertise in Open Mind hyperMILL (Fusion 360, ESPRIT, or Siemens NX experience is a plus).
- Strong understanding of GD&T, CNC tooling, and high-precision machining strategies.
- Experience developing lights-out machining and automated processes.
- Hands-on experience with fixture design and fabrication.
- Experience with advanced probing routines for part alignment and CMM inspection interpretation.
- Strong troubleshooting skills related to machine performance, part accuracy, and process optimization.
- Experience with high-performance materials such as titanium, Inconel, and other nickel-based alloys.
- High attention to detail and a results-driven mindset.
Preferred Skills & Qualifications
- Experience modifying post-processors for CAM software.
- Experience programming and working with automation systems, including robotic loading (UR, Fanuc, etc.).
- Familiarity with Haas, Okuma, GROB, and Mikron machines and their respective controls (OSP, Heidenhain, Haas).
- Background in post-machining of additively manufactured components.
Physical Demands
- Standing for extended periods
- Lifting/moving objects up to 50 lbs
- Working in an industrial environment requiring PPE (eye protection, hearing protection, etc.)
