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:
30 hours/week- Onsite presence required (Boulder, CO) Candidates must reside within commuting distance of our Boulder, CO office.
