Why we read it this way (6)
This role is primarily a Systems Engineering / biomedical instrumentation position; 15-1299 (Computer Occupations, All Other) is used as the closest available code, but the day-to-day work is hardware/systems integration in a biotech context rather than a pure software or IT occupation — the confidence in the occupation is Low.
The JD titles the role 'Senior Systems Engineer' but the hard minimum experience requirement is only 1 year in a relevant engineering role, which supports a Mid-level assessment rather than Senior.
MATLAB and Python are listed as an either/or requirement ('a year of experience with MATLAB or Python') — both are captured as required with each listed as an alternative to the other.
The data visualization/statistical tool requirement (JMP, Minitab, or Tableau) is framed as 'working knowledge of at least one' — captured as a single required skill with the named tools as alternatives.
The posting notes the role may be based at either the South San Francisco, CA headquarters or the Bridgewater, NJ Smart Factory; South San Francisco (SF Bay Area CBSA) is used as the primary location given it is listed as company HQ.
No compensation figures are provided in the posting.
