What is a substrate engineer?

A Substrate Engineer is a professional who specializes in designing, developing, and optimizing the underlying frameworks, often referred to as substrates, for electronic devices or software platforms. In the context of electronics, they work with materials and technologies that form the physical base for circuits and chips, ensuring performance, reliability, and manufacturability. In software, especially blockchain, a Substrate Engineer focuses on building and customizing blockchains using the Substrate framework, handling core logic, consensus, and runtime modules. Their role is crucial for creating robust and scalable systems tailored to specific application requirements.

What are the key skills and qualifications needed to thrive as a substrate engineer?

To thrive as a Substrate Engineer, you need a strong background in materials science, semiconductor fabrication, and electrical engineering, often supported by a relevant engineering degree. Familiarity with industry-standard design tools like Cadence or Mentor Graphics, as well as experience with substrate modeling, PCB design, and analysis software, is typically required. Excellent problem-solving skills, attention to detail, and effective communication are crucial soft skills for collaborating across multidisciplinary teams. These qualifications are essential for ensuring high-quality, reliable substrate designs that meet performance, manufacturability, and cost requirements in advanced electronics manufacturing.

What are some common challenges substrate engineers face when working on high-density interconnect (HDI) designs?

Substrate Engineers often encounter challenges related to managing signal integrity, thermal performance, and miniaturization when working with HDI designs. Balancing the need for dense routing with electrical performance can be complex, especially as device sizes shrink and layer counts increase. Collaboration with PCB designers, materials scientists, and manufacturing teams is crucial to address these issues and ensure the substrate meets both design and production requirements. Keeping up with evolving technologies and industry standards is also essential for success in this role.

What is the difference between Substrate Engineer vs Semiconductor Process Engineer?

AspectSubstrate EngineerSemiconductor Process Engineer
CredentialsBachelor's or Master's in Materials Science, Electrical Engineering, or related fieldsBachelor's or Master's in Electrical Engineering, Chemical Engineering, or related fields
Work EnvironmentResearch labs, fabrication facilities, semiconductor manufacturing plantsCleanrooms, fabrication facilities, process development labs
Industry UsageSemiconductor manufacturing, electronics, integrated circuitsSemiconductor fabrication, chip production, process optimization
Common Search/ComparisonYesYes

Substrate Engineers focus on developing and optimizing the materials and layers used in semiconductor devices, while Semiconductor Process Engineers work on the overall manufacturing processes to produce chips efficiently. Both roles require similar educational backgrounds and often collaborate within the semiconductor industry, but their specific responsibilities differ in scope and focus.

Job description

ABOUT LUMILENS
At Lumilens we are building the critical photonics infrastructure that powers tomorrow's AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.
We're a well-funded startup backed by Mayfield and led by veterans who've built and scaled some of the most transformative technologies in the industry. This isn't incremental innovation, it's a ground-floor opportunity to rethink the optical layer from the silicon up. You'll work alongside a team of world-class engineers solving some of the hardest challenges in optics, systems, and scale. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow.
If you're looking for mission, momentum, and the chance to make an outsized impact jump on the rocket ship. We're just getting started.
Position Overview
We are seeking a hands-on Component Process Engineer to serve as the primary substrate engineering interface between Lumilens' hardware design teams, package manufacturing teams and worldwide substrate suppliers.
This role focuses on FR4 substrate or PCB from new technology development, process development to qualification of the suppliers. The candidate must have solid hands-on experience in FR4 substrate/PCB product development, very familiar with mSAP/HDI/Any_Layer manufacturing process. Engage with substrate/PCB design team during early development phase to provide DFM based on different PCB suppliers' manufacturability.
This position is ideal for an engineer who combines deep Material/Chemistry/Mechanical/Electrical knowledge with a passion for manufacturing process excellence, supplier development, and cross-functional execution at a global scale.
Key Responsibilities
• Identify, develop and qualify FR4/PCB substrate suppliers worldwide.
• Lead DFM/DFT/DFR of PCB substrates, risk analysis and mitigation plan with suppliers.
• Lead FR4/PCB quality control, failure analysis and reliability tests.
• Engage with packaging production teams during the process development from SMT, die attach, wire bond, active alignment and testing.
Required qualifications
• B.S. or M.S. in Material, Chemistry or Mechanical Engineering.
• 8+ years of working experience in FR4 substrate or PCB development or manufacturing, with in-depth knowledge in mSAP process, Any-Layer HDI process, for high-speed optical transceiver applications. Must be very familiar with all the equipment, typical materials and the typical process capabilities.
• Familiar with PCB layout tools such as Cadence, mechanical design tools such as Solidworks, statistical tools such as JMP.
• Working knowledge of PCB test methodologies.
• Familiar with FMEA, Control Plan, SPC, 8D, etc.
• Fluency in English to communicate with English speaking stakeholders.
• 30~50% travel in Asian countries.
