Why we read it this way (6)
This is a Building Automation System (BAS) / Controls Specialist role — a domain-specific technical occupation that sits between field engineering and IT. 15-1299 (Computer Occupations, All Other) is the best available fit; 15-1244 is a plausible runner-up given the network/systems integration emphasis.
The 6+ years requirement is explicitly tied to Siemens Apogee and Desigo, so it is captured on those skills rather than as a standalone role-level minimum.
A Bachelor's in mechanical engineering is listed as a requirement but is immediately qualified by 'or equivalent experience', so the degree requirement is set to None.
BACnet/LON, Tridium NIAGARA/Distech/Eclypse, Honeywell Webs, Modbus, Alerton, Johnson Controls FX, Staefa, Solidyne, Andover Controls, and Schneider are all listed under a 'preferred' heading and are marked accordingly.
Java and C++ appear under 'Knowledge of Object Oriented Programming' in the qualifications section but are framed as general knowledge context rather than hard gates; AutoCAD is explicitly called 'a plus' — both are marked preferred.
The #LI-Onsite hashtag and #Mesa hashtag confirm this is an on-site role in the Mesa, AZ area (Phoenix-Mesa-Chandler CBSA).
