Commissioning Project Engineer

ThermalWorks LLC has an exciting opportunity for a Commissioning Project Engineer to join the Startup & Commissioning team.

This role is responsible for coordinating project timelines, attending scheduling and planning meetings, and ensuring that startup, integrated system testing (IST), and flush and fill activities are executed on schedule and to ThermalWorks standards. The Commissioning Project Engineer works closely with the mechanical install Project Manager to ensure seamless handoffs from installation through commissioning, and serves as the primary owner of flush and fill procedures in the field. The ideal candidate brings a solid mechanical/HVAC background — including piping systems and commissioning experience — combined with strong organizational and communication skills.

ThermalWorks solutions are sustainable and cutting-edge. For that reason, we are highly selective about the people we bring on board because our work depends on it. Change and progress happen quickly, and we must be able to trust one another to be honest, communicative, reliable, and self-motivated. We seek ultra-creatives and superstar performers with a sense of humility and a hunger to make a positive impact in the world. We offer flexibility and endless growth opportunities to those who can harness their skills and talents and identify how and where to use them to add value. ThermalWorks is one of several “inspired infrastructure” companies that work collaboratively under our parent company, Endeavour Energy, LLC. At the heart of this ecosystem is a diverse group of bright, passionate, dedicated people working together to make a real difference for people and the planet. ThermalWorks is looking for someone to join our team to help us move the needle towards sustainable change. Are you ready to join the journey?
