Location: Santa Clara, CA
Salary: $170k - $180k per year
Role Summary:
We're hiring a Senior Electrical Engineer - Mixed-Signal & Digital Systems to design and deliver the next generation of cavity ring-down spectroscopy (CRDS) instruments. In this role, you will own mixed-signal electronics, schematic capture, and PCB layout, applying best practices in grounding, shielding, and signal integrity. You will also handle incremental firmware maintenance in close partnership with the embedded software architect and consultants. Your work will directly influence the precision, stability, and scalability of systems used worldwide in environmental, industrial, and scientific applications.
Key Responsibilities:
Design and validate mixed-signal circuits and PCBs for high-precision instrumentation
Apply best practices in layout, grounding, shielding, and impedance control to minimize noise and interference
Perform schematic capture and PCB layout in Altium (or equivalent) and run mixed-signal simulations in SPICE or similar tools
Debug and validate designs in the lab using oscilloscopes, logic analyzers, VNAs, and other instrumentation
Perform incremental maintenance of embedded firmware (e.g., driver updates, pin mappings, bring-up tweaks) in collaboration with the embedded architect
Collaborate closely with optical, analog, and mechanical engineers to integrate electronics into complex systems
Document designs, maintain revision control, and contribute to shared engineering standards
Qualifications:
BS/MS in Electrical Engineering or related field
10+ years in mixed-signal circuit and PCB design for high-performance systems
Proficiency in schematic capture and PCB layout tools (Altium preferred)
Experience with mixed-signal simulation (SPICE or equivalent)
Strong grounding, shielding, and signal integrity practices for noise-sensitive systems
Familiarity with FPGA firmware (VHDL/Verilog) and embedded C/C++ for maintenance and bring-up
Strong communication skills and ability to work in multidisciplinary teams
Desired Skills and Experience

Engineering, PCB Board Layout & Design, FPGA, Altium, Mixed-Signal, C/C++
