We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (8)
This posting covers two levels simultaneously: Principal Manufacturing Systems Engineer (5 years + BS, or 3 years + MS, or 1 year + PhD; 2+ years ERP/MES/PLM) and Sr. Principal Manufacturing Systems Engineer (8 years + BS, or 6 years + MS, or 4 years + PhD; 4+ years ERP/MES/PLM). The overall years minimum and salary range reflect the lower (Principal) level as the floor; the upper salary bound ($184,200) is the Sr. Principal ceiling.
A degree is required at the Bachelor's level or higher, but equivalent experience is not explicitly offered as a substitute — however, the JD frames it as 'BS STEM Degree' tied to years of experience tiers rather than as a standalone hard gate, so the degree requirement is set to None per schema rules (the degree modulates years required rather than being an unconditional gate).
The role requires the ability to obtain a DoD Interim Secret clearance prior to start and a full Secret clearance after starting, as well as Special Access Program (SAP) approval — the clearance requirement is set to Secret accordingly.
SAP, MES, and PLM/PDM are listed as hard-gated requirements under Basic Qualifications with explicit years demanded (2+ for Principal, 4+ for Sr. Principal); the lower threshold (2 years) is used as the years demanded since this is a dual-level posting.
Siemens CPLM, SAP S/4 HANA, SAP PEO, SmartMES, Excel, Project, and PowerPoint all appear under Preferred Qualifications and are marked accordingly.
The role is primarily a manufacturing systems/digital-tools analyst function (SME for SAP, CPLM, SmartMES in a manufacturing context) rather than a pure software developer or traditional IT systems administrator, making 15-1211 the best fit, with 15-1299 as a reasonable runner-up given the specialized manufacturing-systems focus.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): SAP S/4 HANA.
Requires a Secret clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
