Senior Mechanical Engineer - Thermal Enclosures & Cooling

Broadcom Inc.; San Jose (CA); On-site; USD 122,000 - 195,000; Full time

Job summary

Broadcom Inc. seeks a Mechanical Engineer with expertise in system enclosure design and liquid cooling to drive high‑power thermal solutions from concept through production.

You will lead lab operations, validate components, and collaborate across EE, thermal, and manufacturing teams to ensure scalable, reliable enclosure systems. You will contribute to design validation, thermal testing, and integration for next‑gen datacenter hardware, with exposure to global contract manufacturers and

Qualifications

• Bachelor’s degree in Mechanical Engineering or related field; 8+ years in enclosure design and thermal validation.
• Proficiency in PTC Creo and Windchill PLM.
• Strong background in heatsinks, heat pipes, vapor chambers, and liquid cooling systems.
• Hands-on experience with thermal measurement technologies, sensors, and lab instrumentation.
• Knowledge of datacenter rack standards (EIA-10, OCP).
• Familiarity with EMI/EMC shielding and compliance design considerations.
• Exposure to compliance and reliability testing (NEBS, shock/vibration, thermal cycling).
• Experience working with global contract manufacturers and suppliers to bring products from prototype to volume production.
• Experience with high-speed cabling design and routing (OSFP copper, optical, and internal cables, including bend-radius management).

Responsibilities

• Lead thermo‑mechanical lab operations, including liquid cooling infrastructure, BGA socket thermal validation, and system‑level testing.
• Own thermo‑mechanical system component validation and troubleshooting, driving solutions from concept through production.
• Develop and qualify advanced thermal solutions (heatsinks, vapor chambers, liquid cooling, manifolds) through vendor collaboration.
• Conduct system‑level thermal tests and correlate results with simulations.
• Define and execute thermal test plans, including documentation and data reporting.
• Design rack‑mount enclosures and system components based on production requirements, collaborating with cross‑functional teams (EE, thermal, compliance, manufacturing).
• Manage vendor relationships for thermal solution components (heatsinks, manifolds, fans, cooling hardware).
• Troubleshoot and resolve system‑level thermal issues in high‑power prototypes.
