PROMIS / MES Experience

PROMIS MES experience is highly desirable, particularly experience with PROMIS on VAX/VMS, including Datalink, Interactive Scripts, ODS, and VMS/DCL scripting. However, PROMIS experience is not essential. Candidates with strong experience managing and supporting other MES platforms in complex manufacturing environments are encouraged to apply. Proven MES experience, combined with strong manufacturing knowledge, technical leadership, and the ability to learn new platforms, will be equally valuable.

PROMIS / VAX / VMS, Oracle SQL and manufacturing databases, Linux and modern server environments, MES integration with ERP, Quality, Engineering, Automation, and other manufacturing systems, MES modernization and legacy‑system transformation, Manufacturing cybersecurity / OT environments, ITIL or similar service‑management practices, Semiconductor, wafer fabrication, electronics, or high‑tech manufacturing.

The Ideal Candidate

We are looking for a strong manufacturing IT and MES leader, not someone limited to a single platform. You will combine technical expertise, operational ownership, people leadership, and strong business partnership to keep manufacturing running reliably today while helping shape the technology of tomorrow.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, sex, gender, gender expression, sexual orientation, age, marital status, veteran status, or disability status.
