About The Position

Electrical Engineer II will serve as a technical lead within the CCI, driving the architecture and development of next-generation laboratory electronic products. You will take ownership of the full product lifecycle—from initial concept and complex circuit design to final compliance and manufacturing release. This role requires a seasoned engineer capable of solving sophisticated hardware challenges in low-noise instrumentation and quantum photonics, while providing technical oversight to junior staff.

Requirements

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).
