Interested in getting in at the ground floor of a new, disruptive company attacking an important multi-billion-dollar problem? Businesses and consumers continue to demand increasing data services at an exponential rate -- streaming, deep learning, analytics, loT connectivity, and more. What this means is higher performing CPUs, components, servers and ultimately Data and Edge computing centers, all generating excessive heat that is increasingly difficult to manage with traditional cooling systems. Accelsius is developing revolutionary direct-to-chip, 2-Phase cooling technologies that empower and enable Server OEMs, Data Centers, Edge Computing Operators, and 5G Edge deployments to meet performance, sustainability, scale, and cost goals while serving this high-growth market for data services.

Accelsius is looking for a Mechanical Engineer to help create leading-edge cooling solutions for the computer industry. This role will include the design and creation of cooling system assemblies, focusing on evaporator plates used in 2-phase cooling applications.

Role Responsibilities

  • Develop cold plates and other assemblies for 2-phase cooling solutions
  • Perform FEA on assemblies to confirm performance and suitability for enterprise data center applications
  • Assist in validating thermal and mechanical performance, and directing testing and test requirements as needed
  • Work with other engineers to ensure compatibility with designed assemblies in the greater cooling system, including generating specifications and assisting in design reviews
  • Create drawings required for manufacturing and other documentation (user guides, service manuals)

Qualifications For This Role Include

  • B.S. or higher degree in Mechanical Engineering
  • 5 years of experience with progressively increasing responsibility
  • Sheet metal and chassis experience preferred
  • Thermal engineering experience preferred, with experience in 2-phase cooling technologies
  • Strong mechanical design and integration skills using modern 3D modeling tools

  • Ability to lead mechanical developments from concept to release
  • Experience using SolidWorks
  • Preferred experience with cold-plate design for modern processors/GPUs or other similar power electronics
  • An Agile, team player
