- Proficiency in AutoCAD; MS Visio experience strongly preferred
- Familiarity with ASHRAE principles as applied to controls design
- Experience supporting large, complex facilities strongly preferred
- Ability to interpret mechanical plans and sequences without hand‑holding
- Strong attention to detail and documentation quality
- Someone who understands how designs actually get built
- Someone who asks “will this work in the field?” before issuing drawings
- Someone comfortable owning their designs, not just drafting them
- Experience preferred — training is available, babysitting is not
