Get Access To All JobsJob Description:
We are looking for an experienced AI Systems Thermal Engineer to lead the end-to-end thermal design, simulation, optimization, and physical validation of Direct-to-Chip (D2C) liquid cooling solutions for next-generation AI accelerators and high-density compute platforms.
In this role, you will own the thermal-hydraulic performance of custom cold plates, interface materials, and fluid delivery subsystems—ensuring our high-power ASICs operate within safe thermal limits at peak workloads. You will collaborate closely with silicon package designers, board layout teams, mechanical housing engineers, and manufacturing partners from concept through mass production.
Key Responsibilities:
- Thermal & CFD Modeling: Build and run detailed Computational Fluid Dynamics (CFD) and thermal-resistance network models to evaluate temperature distribution, pressure drop, and flow balancing across cold plates, trays, and racks.
- Advanced Technology Implementation: Research advanced cooling technologies and develop integration and test plans to validate these technologies and convert them into production solutions.
- Cold Plate Design & Optimization: Co-design high-performance liquid cold plates with strategic industry partners to cool high-heat-flux AI processors.
- Thermal Interface Materials (TIM): Specify, select, and qualify thermal interface materials for large, high warpage, devices to minimize contact resistance between silicon dies and cold plates on large devices.
- System & Hydraulic Integration: Design coolant flow paths, quick-disconnects (QDs), hoses, and cold-plate retention/loading mechanisms in alignment with server chassis and OCP (Open Compute Project) standards.
- Lab Validation & Testing: Plan and execute physical thermal testing in the lab—including thermocouple instrumentation, pressure/flow mapping, thermal test vehicle (TTV) bring-up, and simulation-to-test correlation.
- Cross-Functional Collaboration: Partner with mechanical, electrical, firmware (thermal control algorithms), and supply chain teams to drive PCBA, tray and system level designs from NPI (New Product Introduction) to high-volume manufacturing.
Qualifications & Requirements:
- Education: Bachelor’s or Master’s degree in Mechanical or Thermal Engineering (M.S. preferred), or equivalent.
- Experience: Bachelors plus 8+ years of experience, or Masters plus 6+ years of experience. Hands-on experience in thermal/mechanical design for high-power electronics, AI hardware, servers, or HPC systems. Proven, direct experience designing and deploying Direct Liquid Cooling (DLC) systems, specifically liquid cold plates, coolant distribution units (CDUs), and manifold loops.
Technical Skills:
- Electronics Cooling: Deep understanding of single-phase and/or two-phase heat transfer, fluid dynamics, pressure drop calculations, and electronics packaging interactions. Experience with air cooled systems also an asset.
- Simulation Tools: High proficiency in CFD and thermal analysis software (preferably Flotherm, FloEFD, and MacroFlow).
- Lab Instrumentation: Experience with thermal data acquisition systems, flow meters, pressure transducers, and lab automation (Python, MATLAB, or LabVIEW).
- CAD & Mechanical Design: Experience with electronics packaging and CAD platforms, preferably CREO, an asset.
Compensation and Benefits
The annual base salary range for this position is USD To USD.
As a valued member of our team, you'll be eligible for a discretionary annual bonus and the opportunity to receive not only a competitive new hire equity grant, but also annual equity awards, connecting your success directly to the company's growth. All subject to relevant plan documents and award agreements.
Broadcom offers a competitive and comprehensive benefits package: Medical, dental and vision plans, 401(K) participation including company matching, Employee Stock Purchase Program (ESPP), Employee Assistance Program (EAP), company paid holidays, paid sick leave and vacation time. The company follows all applicable laws for Paid Family Leave and other leaves of absence.
Broadcom is proud to be an equal opportunity employer. We will consider qualified applicants without regard to race, color, creed, religion, sex, sexual orientation, national origin, citizenship, disability status, medical condition, pregnancy, protected veteran status or any other characteristic protected by federal, state, or local law.

Search Staff Systems Engineer Jobs in CaliforniaStaff Systems Engineer Jobs in California: Frequently Asked Questions
Which companies in California sponsor visas for staff systems engineers?
Large technology employers including Google, Apple, Meta, Cisco, and Qualcomm have consistent LCA filing histories for staff-level systems engineering roles in California. Defense and aerospace firms such as Northrop Grumman and Raytheon also sponsor for systems engineers, particularly in Southern California. Mid-size cloud infrastructure and semiconductor companies in the Bay Area and San Diego are active sponsors as well.
Which visa types realistically apply to staff systems engineer roles in California?
H-1B visa is the most common path, as staff systems engineer roles qualify as specialty occupations requiring a directly related engineering degree. Canadian and Mexican nationals may qualify under TN visa status as engineers under USMCA. Australian nationals can pursue the E-3 visa under the same specialty occupation standard. F-1 OPT and STEM OPT apply for recent graduates with STEM-designated engineering degrees. EB-2 and EB-3 green card pathways are also available through PERM labor certification for longer-term sponsorship.
Which cities in California have the most staff systems engineer sponsorship jobs?
San Jose and the broader Bay Area account for the highest concentration, driven by hyperscalers, semiconductor firms, and cloud infrastructure companies headquartered there. San Francisco hosts numerous platform and infrastructure engineering teams at late-stage startups. Los Angeles and San Diego are significant hubs for defense, aerospace, and embedded systems roles, with Northrop Grumman, Raytheon, and Qualcomm among the notable employers in those metro areas.
How to find staff systems engineer visa sponsorship jobs in California?
Migrate Mate lists staff systems engineer roles in California from employers with verified visa sponsorship history, letting you search specifically for companies that have filed LCAs for engineering positions in this state. This is more targeted than general job searches because the results are filtered to confirmed sponsors. Searching by city within California on Migrate Mate helps narrow results to Bay Area, Los Angeles, or San Diego clusters depending on your preference.
Are there state-specific factors that affect visa sponsorship for staff systems engineers in California?
California's concentration of technology, defense, and semiconductor employers means LCA filing volume for systems engineering roles is among the highest of any U.S. state. Many Bay Area employers maintain dedicated immigration teams familiar with H-1B, E-3 visa, and TN processes for senior engineers. California's public university system, including UC Berkeley and UCLA, also creates a strong pipeline of STEM OPT-eligible candidates that local employers regularly onboard at the staff level.
What is the prevailing wage for sponsored staff systems engineer jobs in California?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
