About the role

We are seeking an experienced and talented Senior Hardware Engineer to join our hardware development efforts. This position offers the opportunity to design, develop, and test advanced hardware systems in a challenging and innovative quantum technology environment.

Responsibilities

• Support the development of platforms based around classical and quantum photonics as a senior hardware engineer.
• Design custom electronics using Altium Designer alongside other hardware engineers.
• Evaluate critical component performance via board-level and system-level lab testing (ADCs, DACs, FPGAs, TDCs, etc.).
• Collaborate with firmware engineers, software engineers, and quantum scientists during lab testing phases.
• Work with contract manufacturers to procure custom electronics, addressing and mitigating design changes as needed.
• Validate the performance of custom electronics through lab testing and document any issues uncovered.
• Maintain documentation for milestone events, including theory of operations, manufacturing documentation, and validation testing results.
• Integrate hardware into complete systems by working closely with mechanical, firmware, and FPGA engineers.

Requirements

• Bachelor of Science (BS) in Electrical Engineering or Computer Engineering (EE or CE) from an accredited university.
• BS in EE or CE with 8+ years of experience, or MS in EE or CE with 4+ years of experience.
• Proven experience designing PCBs from schematic capture, layout design, and review using an ECAD suite (Altium preferred).
• Familiarity with PCB design best practices related to Signal Integrity, Power Integrity, and EMI/EMC compliance.
• Strong foundation in PCB design related to DFM, DFT, and DFA best practices.
• Strong electrical engineering fundamentals in Analog, Power, and Digital Electronics.
• Advanced experience with voltage regulators, LDO, and switch mode power supplies (SMPS).
• Experience with analog electronics design (op-amps, TIAs, filters, etc.).
• Experience with digital electronics design (Logic Gates, Flip Flops, Microcontrollers, RAM, ROM, Flash, etc.).
• Advanced knowledge of simulation tools such as SPICE.
• Strong experience with low to medium-speed digital interfaces and protocols (I2C, CAN, UART, SPI, etc.).
• Hands-on experience with board bring-up, debugging, testing, and integration using lab instruments (DMMs, Oscilloscopes, Logic Analyzers, Spectrum Analyzers).
• Able to code in C, C++, MATLAB/Octave, or Python.
• Working knowledge of Verilog is a plus.
• Able to lift weights up to 50 lbs occasionally.
• Excellent problem-solving, analytical, written, and verbal communication skills.
• Detail-oriented.

Preferred Qualifications

• Master of Science (MS) degree in Electrical Engineering or Computer Engineering (EE or ECE).
• Experience designing electronics with complex computing devices such as FPGAs, MCUs, CPUs, DSPs, etc.
• Experience working with optoelectronics.
• Experience with high-speed serial protocols (USB, PCIe, Ethernet, etc.).
• Experience with RF analog, digital, and mixed-signal electronics.
• Experience designing systems to meet compliance and certification requirements (e.g., CE/FCC).
• Experience integrating custom ASICs into designs.
• FPGA/SoC/MCU lab validation with lab equipment.
• Experience writing low-level firmware (C, Verilog, VHDL, etc.).
• Experience with manual board prototyping/refurbishing using soldering irons and hot air guns.
