CONTRACT Sr. Thermal Engineer

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. Relocation assistance is not available. Only local candidates will be considered

Compensation: $60-80/ hour, 1099 Contract
