Job description

Electrical Engineer II - 977 at Quantinuum, US Broomfield, CO. A mid-level full time position in the Quantum Computing Hardware team, listed under hardware engineering.

We are seeking an Electrical Engineer II in our Broomfield CO location. In this role, you will design and deliver electrical systems that control our world-class quantum computers. You will work cross-functionally to drive innovation, solve complex technical challenges, and contribute to next generation’s technologies aligned with our research and production-focused objectives. The EE portfolio of products includes ADC/DACs, FPGA-based digital control, servo signal processing, laser locking and control, low-noise analog, motor control loops, low-light detection, and electrical interface electronics.

All applicants for placement in safety-sensitive positions will be required to submit a pre-employment drug test.

WE VALUE

• Demonstrated experience with one or more focus areas (FPGA, analog, RF, controls).
• Schematic entry and board layout experience (Altium PCB software preferred).
• FPGA design and verification experience, including Xilinx software and IP, as well as VHDL, Verilog, and/or System Verilog.
• Ability to troubleshoot systematically and drive issues to closure.
• Proficiency in lab instrumentation and automated test setups.
• Working knowledge of signal integrity, noise, and filtering concepts.
• Experience with embedded control loops or digital signal processing is a plus.
• Strong communication and collaboration skills.

Quantinuum is a leading quantum computing company delivering a full stack platform designed to make quantum computing deployable in real-world environments. With active engagements spanning pharmaceuticals, material science, financial services, government, industrial sectors, and leading academic and research institutions worldwide, we are helping organizations unlock the transformative potential of quantum computing.

Responsibilities

• Independently execute subsystem-level designs with limited oversight.
• Perform design, simulation, and validation of moderately complex circuits (analog, digital, or RF).
• Develop and debug FPGA modules, signal processing blocks, or control loops.
• Analyze test data and identify root causes of issues.
• Contribute to board bring-up and system integration activities.
• Document designs, test procedures, and results.
• Provide technical input in design reviews
• Design products using DFx best practices
• Work closely with cross functional teams including mechanical engineers, software engineers, optical engineers, & scientists to develop electronics for use in our quantum computers

Requirements

• Bachelor’s degree required
• 2+ years of electrical engineering experience.
• Due to Contractual requirements, must be a U.S. Person defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status.
• Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.
