Senior Substrate Designer

At Elevate Semiconductor, we empower semiconductor and system test customers by creating world-class ICs that tackle the industry’s most complex automated test equipment (ATE) challenges. Our innovative team designs the lowest‑power, highest‑density solutions to drive down cost of test while pushing performance forward.

We are seeking an experienced Senior Substrate Designer to support the development of advanced IC packaging solutions. In this role, you will design high performance substrates that enable next generation semiconductor products. You will work closely with design engineering test engineering and operations teams to ensure high quality manufacturable solutions that meet electrical mechanical and thermal requirements.

Although our goal is to hire someone full time, we are open to considering consultant based project work given the nature of the responsibilities.

• Create complex multi layer substrate designs for high speed mixed signal and power ICs
• Develop detailed layout including routing stackups via structures and design rules
• Optimize layouts for signal integrity power integrity and thermal performance

• Partner with IC design teams to understand die level requirements and translate them to substrate architecture
• Work with packaging operations suppliers and manufacturing partners to ensure design feasibility and high yield
• Collaborate with test and product engineering to support bring up qualification and debug

• Define substrate design guidelines standards and best practices
• Conduct design reviews and provide expert guidance on tradeoffs and constraints
• Create and maintain documentation including drawings BOMs and release files

• Perform signal integrity power integrity and thermal simulations as needed
• Validate layout decisions with modeling and characterization data
• Support root cause analysis for substrate related issues in development and production

• Bachelor’s degree in electrical engineering, Mechanical Engineering, Materials Engineering or related field
• 5+ years of experience in substrate design or advanced IC packaging
• Strong expertise with substrate CAD tools such as Cadence Allegro or equivalent
• Deep understanding of high speed routing impedance control stackup design via structures and manufacturing constraints
• Knowledge of SI and PI fundamentals including loss crosstalk return paths and decoupling strategies
• Experience working with OSATs and substrate vendors

• Experience with advanced packaging technologies such as flip chip 2.5D 3D or chiplet architectures
• Familiarity with thermal modeling and materials selection
• Strong documentation and communication skills
• Ability to work effectively in a fast paced collaborative environment
