Principal Hardware Engineer

At Atom Computing, we build quantum computers using arrays of optically trapped neutral atoms that will empower customers to achieve unprecedented computational breakthroughs. Join a world-class team of scientists, engineers, and business professionals to advance the state-of-the-art in quantum computing.

Atom Computing is seeking a hands‑on Principal Hardware Engineer to lead the architecture, design, and deployment of custom electronic assemblies for the control system of our quantum computer. In this role, you will drive hardware strategy across multiple concurrent projects while remaining deeply engaged in the tactical engineering work.

This position is located in Boulder, Colorado, and will report to the Control Systems Manager.

• Design high‑level system architectures for instruments, including multiple PCBAs for various functions, and collaborate on FPGA/processor selection, power and clocking schemes, analog and RF front‑end designs, and DAC and ADC.
• Collaborate with quantum engineers and other groups to understand system needs, discuss solutions, and define design requirements.
• Perform board‑level circuit design, schematic capture, and PCB layout in Altium Designer for custom control system hardware.
• Prepare detailed technical specifications and design documentation, and assist with reviewing schematics and layouts of custom electronic designs.
• Actively participate in bring‑up, verification, and testing of control system hardware, collaborating closely with FPGA, firmware, and software engineers.
• Own technical relationships with contract electronics manufacturers and suppliers, driving Design for Manufacturing (DFM) strategies to support production and scaling operations.
• Mentor other team members in hardware design.

• BS or MS in Electrical Engineering, Computer Engineering, or a related technical field.
• 10+ years of relevant postgraduate professional experience in board‑level analog and digital circuit design, preferably with Altium Designer.

• Self‑motivated, collaborative, and driven to work effectively in a fast‑growing startup environment.
• Ability to effectively communicate and collaborate with a diverse team of experimental physicists, hardware, and software engineers.
• Willingness to learn physics concepts to put work in context.
• Experience in a full design cycle, from concept and schematic capture through to layout, fabrication, and initial board bring‑up.
• Working knowledge of PCB design best practices and keen attention to detail.
• Mixed‑signal design experience.
• Demonstrated proficiency with electronic test equipment (e.g., oscilloscopes, spectrum and logic analyzers, signal generators) for the bring‑up and debug of prototype electronics assemblies.
• Capable in scripting languages (e.g., Python) for basic data acquisition, instrument control, and automation of hardware test and characterization.
• Experience working on boards with complicated ICs (FPGAs, processors, etc.) requiring multiple power supplies, high‑speed buses, and high‑speed memory interfaces.

• RF front‑end and high‑speed ADC/DAC design experience.
• Familiarity with RF design concepts and/or software‑defined radio.
• Experience with multi‑gigabit serial transceiver lane design, evaluation, and equalization.
• Experience designing high‑speed memory interfaces.
• Experience with high‑speed digital and analog I/O and connector/cable selection and characterization.
• Experience working in a Linux environment.
• Familiarity with the MicroTCA, PXIe, or similar pluggable instrument standards.
