We are seeking a highly experienced and self-motivated Staff Thermal Engineer to lead the design, simulation, and validation of thermal solutions for complex electronic systems. The ideal candidate is a critical thinker with a rigorous attention to detail, capable of working independently with minimal supervision, while managing multiple high-priority projects under tight deadlines. This role requires deep expertise in both traditional and advanced thermal management approaches across electronic packaging technologies.

  • Independently lead thermal simulation and characterization of electronic assemblies, including MCMs, interposers, substrates, PCBs, cold plates, and system-level components.
  • Develop and implement innovative thermal management strategies with a focus on advanced liquid cooling and high-performance air-cooling technologies.
  • Validate cooling solutions through end-to-end thermal modeling (e.g., Ansys IcePak, Fluent) and physical prototype testing - ensuring results are accurate, reliable, and replicable.
  • Collaborate with cross-functional teams (electrical, mechanical, packaging, manufacturing) to drive thermal performance optimization in early-stage designs.
  • Deliver high-quality technical presentations and documentation, clearly communicating complex findings to technical and executive audiences.
  • Publish and present in conferences and industry forums to advance the company's visibility in the thermal engineering space.
  • Develop and execute comprehensive test plans to ensure manufacturability, reliability, and cost-effectiveness of proposed solutions.
  • Bachelor's degree in Mechanical, Thermal, or related engineering field.
  • Proficiency in using ANSYS DesignModeler to create 3D geometry for thermal simulation purposes.
  • Experience using DesignModeler's parametric modeling features for geometry automation and design exploration.
  • Strong proficiency with simulation and modeling tools such as Ansys IcePak, Fluent, and SolidWorks, emphasizing modeling accuracy and interpretation.
  • Minimum 5-7 years of hands-on experience designing and validating thermal solutions for electronic systems, with increasing scope and leadership responsibility.
  • Proven track record of independent ownership of complex thermal engineering projects from concept through deployment.
  • Deep expertise in air-cooling techniques (e.g., vapor chambers, heat pipes, TIMs) and familiarity with liquid cooling systems.
  • Demonstrated ability to meet aggressive deadlines and manage priorities across multiple high-impact programs.
  • Excellent written and verbal communication skills, with attention to technical clarity and completeness.
  • Master's or PhD in Mechanical, Thermal, or related field.
  • 8-10+ years of experience in thermal design for microelectronics, high-performance computing, or advanced packaging technologies (e.g., 2.5D/3D).
  • Experience with JEDEC thermal standards, advanced packaging, and system-level integration.
  • Deep understanding of interconnect processes and materials such as solder bumping, copper pillars, and thermally conductive adhesives.
  • Familiarity with industry-leading thermal practices for high-density, high-power electronics and heterogeneous integration platforms.
  • Competitive compensation (salary, equity, and bonuses) and comprehensive benefits are designed to foster work-life balance, care for your health, protect your finances, and help you save and invest for the future.
  • Generous paid time away from work, including flexible time off, holidays and sick time, health and wellness initiatives, and a charitable match program to help you give back to your community.
  • Great benefits, which vary by location and can be site-specific: employee discounts, transportation reimbursements, and fitness facilities.
  • A flexible, hybrid work environment combining the best of in-office collaboration and community-building along with the benefits of working from home.
