Job description

About the Role
We're looking for an experienced Mechanical or Thermal Engineer to join our team on a short-term contract focused on designing and validating a dedicated cooling system for datacenter racks. This is a hands-on, high-impact role where you'll own technical analysis, drive design recommendations, and work directly with our engineering team to deliver a tested, production-ready solution.
This is the right role for someone who thrives in environments where the specifications aren't always handed to you — someone who can assess the situation, gather data, and bring a confident recommendation forward.
 
What You'll Do
•          Analyze airflow within datacenter rack configurations and recommend design modifications to optimize thermal performance
•          Evaluate off-the-shelf rack-mounted active cooling units (air conditioning) for fit and performance
•          Develop and execute test and validation plans, including four-corner chamber testing
•          Perform thermal simulation using SolidWorks Flow Simulation or comparable CFD tools
•          Define and program software control systems (e.g., Modbus) to maintain precise temperature and humidity within enclosed rack environments
•          Collaborate closely with the onsite team while also driving independent analysis and decision-making when data is limited
 
What We're Looking For
•          Bachelor's degree in Mechanical Engineering, Thermal Engineering, or HVAC Engineering (Master's a plus)
•          8+ years of engineering experience with demonstrated depth in datacenter or industrial thermal/cooling systems
•          Hands-on experience with datacenter rack cooling, CRAC/CRAH units, or rack-mounted active cooling equipment
•          Proficiency in CFD/flow simulation software (SolidWorks Flow Simulation strongly preferred)
•          Experience developing control algorithms to regulate temperature and humidity within tight tolerances in enclosed environments
•          Familiarity with industrial communication protocols such as Modbus
•          Ability to work onsite regularly and engage collaboratively with a cross-functional team
•          Comfortable operating with ambiguity and light specifications — you bring solutions, not just questions
Engagement Details
•          Contract duration: 9 months
•          Hours: 40 hours/week
•          Onsite presence required (Boulder, CO)
