Electrical Engineer – Speed Digital Hardware

Bright Silicon Technologies, located in Pleasanton, CA, is seeking an electrical engineer with expertise in board design and bring‑up, looking to take ownership of design and manufacture of complex multi‑layer boards. Your first challenge will involve the architectural integration of a high‑pin‑count FPGA; performing precision routing of high I/O count traces while maintaining signal integrity. Additional design challenges will involve the integration of ASIC‑chiplets to drive our high‑voltage MEMS, working with our ASIC design house, and choosing materials and architectures that meet thermal and signal integrity specifications.

You will work cross‑functionally with internal and external design teams to meet requirements and product definitions. This is a high‑impact position inside a small but growing company that is pioneering the state‑of‑the‑art in solid‑state optical beam‑control, seeking innovators and hard workers. If you’re a talented “take on anything” engineer and ready to have a leading role in the future of an exciting technology and valuable company, come join us.

Our pay ranges are determined by role, level, and location. The range displayed above reflects the minimum and maximum pay for this position in the primary location identified in this posting; however, base pay offered may vary depending on internal equity, job‑related knowledge, skills, and experience among other factors. Candidates will be assessed and provided offers against the minimum qualifications of this role and their individual experience.

• Schematic & Layout: Design complex digital circuit boards using industry‑standard EDA tools, focusing on high‑density interconnects (HDI).
• FPGA Integration: Manage the pin‑mapping and routing of ~500 digital I/O lines, ensuring thermal and mechanical constraints are met.
• Signal Integrity (SI): Perform pre‑ and post‑layout SI simulations to validate timing, crosstalk, and impedance matching for high‑speed signals.
• Power Electronics: Design and implement low‑voltage DC‑DC power supplies to provide stable rails for both the local PCB and peripheral boards.
• ASIC/Chiplet Implementation: Lead the transition toward chiplet‑based architectures, strictly monitoring trace capacitance and signal loss.
• Hardware Validation: Bring up initial prototypes in the lab; lead electrical integration and verification.

• Education: Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related technical field.
• Experience: Graduate Degree or 3+ years of experience in high‑speed digital PCB design and layout.
• Technical Proficiency: Proven track record of routing high‑pin‑count processors and working with high‑speed digital interfaces.
• SI Fundamentals: Solid understanding of transmission line theory, impedance control, and electromagnetic interference (EMI) mitigation.
• Power Design: Experience designing buck/boost converters and LDOs for low‑voltage digital rails.
• Communication: Excellent communication skills with experience working with a cross‑functional, distributed team.
• Self‑starter mentality: Have a proactive approach to uncovering risks and managing dependencies.
• System‑oriented: Ability and desire to dive deep into the smallest detail.

• Advanced Modeling: Experience with SI/PI simulation software (e.g., Ansys SIwave, Cadence Sigrity, or Hyper Lynx).
• Chiplet Expertise: Previous experience with ASIC integration or 2.5D/3D packaging concepts and their associated PCB‑level challenges.
• Connectivity: Experience designing custom high‑density connectors or backplane interfaces.
• Materials Knowledge: Familiarity with high‑frequency PCB laminates (e.g., Rogers, Megtron 6) and their impact on signal loss.
