Job description

Cornelis Networks is hiring a talented Entry-Level Thermal Engineer with a foundational understanding of heat transfer and fluid dynamics. In this entry-level role, you will support the design, simulation, and physical testing of thermal management solutions for the next-generation Cornelis Networks Fabric platforms. You will work closely with senior thermal, mechanical, and electrical engineers to evaluate high-performance electronics cooling from the component level up to the system level. 


The ability to effectively focus a significant amount of computational power on solving critical problems through the use of artificial intelligence, data analytics, and modeling/simulation techniques is vital to many scientific, commercial, and government organizations, and it is the mission of Cornelis Networks to deliver innovative purpose-built interconnect solutions that enable our customers to optimally apply vast computational resources to solve the world’s toughest problems. 




Key tasks include: 

  • Lab Testing & Validation: Set up and execute thermal measurements and qualification testing. Apply thermocouples, manage data acquisition (DAQ) systems, and collect empirical data to validate thermal designs. 
  • Simulate & Model: Assist senior engineers in executing computational fluid dynamics (CFD) and thermal simulations, including modeling, pre-/post-processing, and analysis. 
  • Component Thermal Design Support: Support the thermal design and evaluation of PCBs, heat sinks, and thermal interface materials (TIMs). 
  • Data Analysis & Reporting: Analyze thermal test data, summarize findings, and contribute to formal engineering test reports and guidelines. 
  • Cross-Functional Collaboration: Partner with mechanical, electrical, and manufacturing teams to understand design constraints and support product readiness. 


Minimum qualifications 

  • BS in Mechanical Engineering with a focus in Thermodynamics, Heat Transfer, Fluid Dynamics, or Thermal Engineering. 
  • 0-3 years of experience in thermal engineering (internship, co-op, or academic lab experience qualifies). 
  • Hands-on experience in a lab environment: familiarity with thermal sensors, data acquisition, and test execution. 
  • Familiarity with 3D MCAD tools (CREO preferred, SolidWorks acceptable). 
  • Familiarity with basic CFD tools and concepts (academic or industry exposure to Cadence Celsius EC, Siemens Flotherm, or Ansys Icepak is highly desired). 
  • Understanding of basic cooling methods (conduction, convection, heat sinks, and thermal interface materials). 
  • Excellent communication and interpersonal skills; eager to learn and work in a cross-disciplinary team. 


Preferred qualifications: 

  • MS in Mechanical Engineering. 
  • Scripting experience (e.g., Python, MATLAB) for test automation or thermal data analysis. 
  • Prior experience specifically using Cadence Celsius EC for electronics cooling simulation. 
  • Familiarity with liquid cooling systems, cold plates, or two-phase cooling methods. 
  • Exposure to high-performance computing (HPC) or data center environments. 


Location 

This position is hybrid (on-site with some remote work possible) at the headquarters in the Chesterbrook Corporate Center in Wayne, PA. The successful candidate resides within commuting distance.
