Responsibilities
Lead the design and schematic capture of high-precision analog and digital systems, ensuring optimal signal integrity for low-noise applications
Independently manage PCB layout strategies for complex, multi-layer boards involving high-speed signals, sensitive photonics interfaces, and varied power systems
Lead root-cause analysis for complex system failures and implement long-term design fixes
Coordinate with mechanical, software, and photonics engineers to define system requirements and ensure seamless cross-disciplinary integration
Oversee and guarantee that all products meet rigorous international standards (EMC/EMI, UL, CE) through comprehensive validation planning
Act as a technical resource and provide oversight for early-career engineers, conducting design reviews and promoting engineering best practices
Qualification
Required
5–10 years of professional experience specifically in precision analog design or high-performance instrumentation
BSEE or MSEE or similar from an ABET accredited institution
Demonstrated equivalent knowledge and experience
Proficiency in EDA tools (including multi-layer stack-up and high-speed routing) and advanced SPICE/LTspice modeling for noise floor estimation, thermal behavior, and part tolerancing
Hands-on experience performing advanced measurements of electronics (e.g., 1GHz+ oscilloscopes, spectrum analyzers, vector network analyzers) and characterizing low-level signals
Deep understanding of the design considerations for precision analog design (pico-ampere sensing, low-drift op-amps), high-efficiency power conversion, and high-speed digital integration
Familiarity with embedded digital electronics including: microprocessors, microcontrollers, programmable logic devices, volatile and non-volatile memories, Ethernet, I2C, SPI, UART and USB
Proven ability to author comprehensive Design Specifications, Test Plans, and Manufacturing Instructions; experienced in Design for Excellence (DFX)—specifically for manufacturability and test (DFM/DFT)
Demonstrated success in contributing to cross-functional teams moving products from initial concept through New Product Introduction (NPI) and into low-volume/high-complexity production environments
Proficiency in advanced electronics rework, including fine-pitch SMT soldering and BGA troubleshooting, to facilitate rapid internal prototyping and failure analysis
Experience managing Signal Integrity (SI) and Power Integrity (PI) in sensitive analog-digital hybrid systems to minimize cross-talk and EMI
Architecting automated test environments using Python, LabVIEW, or C/C++ to streamline device characterization and production validation
A proven track record in photonics, laser control electronics, or precision measurement instrumentation, with a deep understanding of the unique noise and stability requirements of these fields
Experience designing systems incorporating FPGAs for signal processing and HDLs (e.g. VHDL or Verilog)
Preferred
Altium Designer is preferred
