Electrical Engineer – Analog / Mixed-Signal

Job Title: Electrical Engineer – Analog / Mixed-Signal Location: Hoboken, NJ Division: Revenue Department: Defense

About Us:

Quantum Computing Inc. (QCi) (Nasdaq: QUBT) is an innovative, integrated photonics company that provides accessible and affordable quantum machines to the world today. QCi products are designed to operate at room temperature and low power at an affordable cost. The Company’s portfolio of core technology and products offer unique capabilities in the areas of high-performance computing, artificial intelligence, cyber security as well as remote sensing applications.

Scope of the Job:

QCi is seeking a mid-level Analog/Mixed-Signal Electrical Engineer to design, simulate, and characterize precision analog, power, and mixed-signal circuits for our Defense Engineering team. Applications include RF front ends, photonics and quantum sensing hardware, and ruggedized systems for communications, computing, AI-at-the-edge, and electromagnetic warfare. This role will work cross-functionally with RF, digital, systems, layout, and test teams to bring hardware from specification through prototype, qualification, and production.

Duties / Responsibilities:

• Design, simulate, and verify analog/mixed-signal blocks to meet noise, bandwidth, linearity, power, and thermal targets (e.g., low-noise amplifiers (LNAs), transimpedance amplifiers (TIAs), ADC/DAC interfaces, precision references, LDOs, and DC-DC converters).
• Own board-level power architecture, signal-chain, and noise budgets for product evaluating trade-offs across cost, power, size, performance, and reliability.
• Develop schematics and guide PCB layout for high-speed, low-noise, high-voltage, or mixed-signal boards, including stack-up, grounding, shielding, and signal-integrity considerations.
• Drive board bring-up and lab characterization using oscilloscope, spectrum analyzer, network analyzer, precision DMM/SMU, thermal chamber to validate performance against specification.
• Debug and resolve hardware issues discovered during bring-up, environmental qualification, or production, partnering with test/manufacturing teams.
• Perform worst-case, tolerance, derating, and reliability analysis for MIL-STD-810 / MIL-STD-461 / DO-160 environments.
• Document design methodology, analysis, and test results; contribute to internal design-reuse libraries and component selection standards.
• Mentor junior engineers and participate in design reviews across the hardware team.
• Contribute to patent filings and technical publications.

Required Skills & Experience:

• Bachelor’s degree in electrical engineering or related field; master’s degree or equivalent practical experience preferred.
• 5 - 10 years of hands-on experience in analog, power, or mixed-signal hardware design, with direct responsibility for board-level or subsystem-level deliverables.
• Demonstrated experience designing circuits (e.g., low-noise amplifiers, TIAs, data-converter front-ends, power supplies) from concept through production.
• Proficiency with industry-standard tools for PCB Design (e.g., Altium Designer or Cadence Allegro), circuit simulation (e.g., LTspice, PSpice, or Spectre), and data analysis (MATLAB or Python).
• Working knowledge of signal-integrity and power-integrity concepts, including noise analysis, grounding, EMI/EMC, and thermal management.
• Hands-on lab experience with RF test equipment (e.g., oscilloscope, spectrum analyzer, network analyzer, source measure unit (SMU), and function/signal generators).
• Strong understanding of photodetector and laser driver circuits, high-speed data acquisition, and low-noise instrumentation.
• Excellent written and verbal communication skills; ability to present technical results to cross-functional stakeholders.
• Must be a U.S. Citizen or Permanent Resident and able to obtain or maintain a government security clearance.

Additional Preferred Skills:

• Master's or Ph.D. in Electrical Engineering with an analog/mixed-signal or power-electronics focus.
• Experience taking hardware through full environmental qualification and into volume production.
• Familiarity with specific standards, e.g., MIL-STD-810, MIL-STD-461, DO-160, IPC Class 3.
• Proficiency in Python, MATLAB, or LabVIEW for simulation and test automation.
• Experience with optical and photonic hardware, cryogenic or vacuum-compatible electronics, and SWaP-constrained designs.
• Prior experience in Defense, aerospace, or instrumentation.
• Existing active security clearance.
