Entry Level Ansys Simulation Jobs in Marcus Hook, PA

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.
