Technical Proficiency

We evaluate your ability to handle the "nuts and bolts" of the job. Strong performance means you can confidently discuss the nuances of equipment selection, the interpretation of blueprints, and the use of factory software.

Be ready to go over:

• Equipment Selection – How you use software to match performance data to project needs.
• Takeoff Procedures – Your methodology for reviewing bid documents and identifying opportunities.

As a Solutions Engineer, your primary objective is to facilitate the success of our sales projects. You will act as the central nervous system for orders, ensuring that everything from the initial quote letter to the final project closeout is handled with precision. You will spend your day interfacing with various factory software tools, managing opportunities within our CRM, and ensuring that shipping information is accurately relayed to our clients.

Beyond the administrative requirements, you will serve as an engineering resource. This includes visiting jobsites to support our sales engineers, assisting with equipment startups, and managing warranty claims or RMAs. You are expected to be a self-starter who stays current with factory literature and software versions, as well as a mentor who is willing to train fellow team members when you gain new expertise.

We seek candidates who combine a strong technical foundation with a service-oriented mindset.

• Must-have skills – A strong technical HVAC background, proficiency in Microsoft Office (specifically Excel), and excellent organizational skills.
• Nice-to-have skills – A B.S. in Mechanical Engineering is highly preferred, though an Associate degree with significant industry experience is acceptable.
• Experience – We look for 1–3 years of directly related HVAC industry experience for our core roles, with an emphasis on those who have managed project cycles from bid to closeout.

Q: How long does the process take? A: While timelines vary by location, our process is designed to be smooth and efficient. You can expect clear communication regarding your status throughout the interview stages.
