Cornelis Networks is hiring a talented Entry Level Mechanical Engineer to join our team, focusing on electronics packaging for High-Performance Computing (HPC) and Artificial Intelligence (AI) systems. This is an exciting opportunity to work with cutting-edge technologies and play a crucial role in designing innovative thermal and mechanical solutions for HPC/AI systems, ensuring optimal performance and reliability.

In this role, you will collaborate with cross-functional teams, including electrical engineers, systems architects, and product designers, to develop and implement thermal management, structural integrity, and cooling solutions for high-power electronic systems.

Key Responsibilities:

• Mechanical Design & Analysis: Assist in designing, analyzing, and validating mechanical systems and components for HPC electronics packaging. Develop detailed 3D models and drawings using CAD software (SolidWorks, Creo, etc.). Perform structural and thermal simulations (FEA/CFD) to evaluate design feasibility, performance, and reliability.
• Thermal Management: Support designing and optimizing air and liquid cooling systems to manage heat dissipation in HPC environments. Work on innovative cooling solutions, including liquid cooling loops, heat sinks, and vapor chambers.
• Packaging & Integration: Collaborate on developing robust packaging solutions for electronic components, considering mechanical stresses, thermal cycling, and environmental conditions. Ensure mechanical designs comply with industry standards (e.g., EIA-310, IPC standards) and meet customer requirements for reliability and manufacturability.
• Prototyping & Testing: Participate in the development of prototypes and coordinate with manufacturing teams for assembly and testing. Conduct thermal and mechanical testing to validate designs and optimize performance.
• Cross-Disciplinary Collaboration: Collaborate with electrical engineers and PCB designers to optimize component placement, airflow, and thermal performance. Work with manufacturing and quality assurance teams to ensure the designs are scalable and meet production standards.

Preferred Qualifications

• Hands-on experience with prototype development and testing.
• Familiarity with industry standards such as EIA-310, OCP, IPC, or MIL-STD for electronics packaging.
• Basic understanding of high-performance computing systems and their specific packaging challenges.
• Experience with Python for automation, data analysis, or thermal simulations.
• Proficiency in CAD software (Creo, SolidWorks, or similar).
• Basic knowledge of FEA and CFD tools (ANSYS, FloTherm, or similar).
• Familiarity with thermal management techniques, especially in high-performance electronic systems.
• Knowledge of materials used in electronics packaging, such as metals, plastics, and thermal interface materials.
• Understanding liquid cooling systems or airflow management for electronics is a plus.
• Strong problem-solving and analytical skills.
• Excellent communication and teamwork skills.
• Detail-oriented with the ability to manage multiple tasks.

Minimum Qualifications

• Bachelor’s Degree in Mechanical Engineering or a related field.
• Experience in mechanical design, preferably in electronics packaging or thermal management.
