CONTRACT Sr. Thermal Engineer

Spectra LogicBoulder, CO
$60 - $80Onsite

About The Position

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.

Requirements

  • 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

Responsibilities

  • 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

Benefits

  • casual, hybrid work environment
  • ample opportunity to learn and grow within the company
  • Work out on your own or with our trainer at one of the on-campus gyms
  • grab lunch or snacks onsite
  • challenge the CEO to a game of pinball
  • grow your career with peers who are second to none
