Job Description

COMPANY OVERVIEW:
AOSense, Inc. is the leading developer and manufacturer of innovative quantum technologies employing atom optics. Our devices use frequency-stabilized lasers and atoms in a vacuum cell to measure accelerations, rotations, magnetic fields, and time with unparalleled accuracy and stability. Our staff includes physicists and engineers with expertise covering a wide array of disciplines. Our teams are dynamic and fast paced since our hardware is cutting edge.

POSITION SUMMARY:
We are seeking a hands-on electrical engineer to design and implement control systems for fieldable atom optic (AO) gyroscopes, accelerometers, absolute gravimeters, gravity gradiometers, inertial measurement units (IMUs),magnetometers, and atomic frequency standards. The control hardware for AO sensors spans a broad range of technologies including low-noise analog, low-jitter digital, rf/microwave, high voltage, microcontrollers, systems on a chip (SoCs), field-programmable gate arrays (FPGAs), and application-specific integrated circuits (ASICs). An ideal candidate will have an unusually broad background covering several of these diverse technologies. As a Senior Electrical Engineer at AOSense, you will work with scientists and engineers to define control system requirements and architectures, will oversee the fabrication and testing of AO sensor control hardware, and will support the completed hardware through the performance validation phase. You will help to guide the development of future generations of quantum-atomic devices as they transition from the laboratory into the field.

RESPONSIBILITIES:

  • Collaborate with physicists, instrument designers, and code developers to specify sensor control requirements and make optimal trade-offs

  • Guide the definition of control architectures for sensors

  • Design low-noise analog, digital, and rf/microwave electronics

  • Iterate existing electronics designs to adapt them for new operating conditions

  • Conduct and participate in design reviews

  • Create schedules and budgets for control system development

  • Create work plans for electronics staff

  • Track progress of electronics staff relative to project schedules

  • Manage outsourced electronics development

  • Collaborate with coders on development of software, firmware, and gateware

  • Document new devices with block diagrams, schematics, interface control documents, bills of material, cable drawings, test procedures, and datasheets

  • Contribute to proposals for further sensor development and applications

Requirements

  • Experience selecting architectures for complex electronic instrumentation

  • Demonstrated expertise in low-noise analog circuit development

  • Deep understanding of noise sources in electronic systems

  • Ability to critically evaluate electronics designs spanning a broad range of technologies

  • Experience supervising and reviewing complex PCB layouts

  • Expertise defining test plans for control electronics

  • Demonstrated success in on-time and on-budget management of electronics development

  • Proficiency with EE CAD tools (e.g., OrCAD, PADS, Altium, LTSpice, Mathcad, MATLAB)

  • Thorough operational knowledge of standard diagnostic equipment (e.g., oscilloscopes, logic analyzers, and spectrum analyzers)

  • Excellent analytical and troubleshooting skills

  • Applicants should thrive in a dynamic environment

  • U.S. Government contracts require applicants to be U.S. citizens or permanent residents

DESIRED EXPERIENCE:

  • Experience with low-noise laser drivers and photodetectors, proportional, integral, differential (PID) control circuits, low-phase noise rf sources, and direct digital synthesizers (DDSs)

  • Expertise developing instruments employing microcontrollers and Xilinx Zynq SoCs

  • Successful implementation of FPGA-based real-time measurement systems

  • Experience managing the development of high-performance ASICs

  • Successful management of code development

  • Familiarity with the qualification of electronics for foreign markets

EDUCATION:
Master's degree or doctorate in electrical engineering with 5 y related experience, or equivalent professional experience

Benefits

  • Salary depends on qualifications and experience

  • Medical and dental

  • Retirement

  • Stock plan

Practice Questions

💡Technical Questions (3)
  • 1.How do you identify and mitigate noise sources when designing low-noise analog electronics for highly sensitive atomic sensors?
  • 2.Walk me through your process for selecting the architecture of a complex control system for an atom optic sensor that requires low-jitter digital, RF/microwave, and high-voltage components.
  • 3.What are the key considerations you enforce when supervising and reviewing complex PCB layouts for mixed-signal instrumentation?
🎯Behavioral Questions (3)
  • 1.Tell me about a time you had to collaborate with physicists or software developers to define control system requirements and make optimal trade-offs.
  • 2.Describe a situation where you managed an electronics development project that was at risk of going over budget or missing its deadline. What did you do?
  • 3.Give an example of a time you had to adapt an existing electronics design for a completely new set of operating conditions. How did you ensure its reliability?
🧩Situational Questions (2)
  • 1.You are defining the architecture for a new fieldable atomic sensor, and the physics team requests an extremely low-noise requirement that would require a costly, custom ASIC. How do you approach this?
  • 2.During the performance validation phase of an AO sensor, you discover an unexpected RF noise coupling into your low-noise analog circuitry from the Xilinx Zynq SoC gateware. How do you troubleshoot and resolve this?
