Job Description

Job Title : RF / RFIC Design Engineer

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 RF/RF Integrated Circuit (RFIC) Design Engineer to contribute to the design, simulation, and characterization of architectures for our Defense Engineering team. Applications include RF front-end ICs, transceivers, or RF subsystems for communications, computing, AI-at-the-edge and electromagnetic warfare. This role will work cross-functionally with systems, test, and product teams to bring the technology from specification through tape-out and production.

Duties / Responsibilities:

• Design, simulate, and verify RFIC blocks to meet gain, noise figure, linearity, and power targets (e.g., low-noise amplifiers (LNAs), power amplifiers (PAs), RF mixers, voltage-controlled oscillators (VCOs), phase-locked loops (PLLs), and switches) using CMOS, SiGe, BiCMOS, or GaAs process technologies.
• Define and own RF system and link budgets, evaluating trade-offs across performance, power consumption, size, and cost.
• Collaborate with engineers and execute RF-aware floorplanning, layout, electromagnetic (EM) simulations, and parasitic extraction to optimize RFIC performance for the target process node.
• Drive silicon bring-up and lab characterization using RF test equipment (vector network analyzer (VNA), spectrum analyzer, noise figure meter, and load-pull) to validate performance against specifications.
• Debug and resolve RF performance issues discovered during bring-up, qualification, or production in collaboration with test and manufacturing teams.
• Support regulatory and standards compliance efforts as applicable to the product (e.g., FCC, 3GPP, MIL-STD).
• Document design methodology, test results, and lessons learned; contribute to internal design-reuse libraries and IP development.
• Mentor junior engineers and participate in design reviews across the RF/analog 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 RF/RFIC design, with direct responsibility for block- or system-level deliverables.
• Demonstrated experience designing RF blocks across CMOS, SiGe, InP, and GaAs process technologies
• Proficiency with industry-standard Electronic Design Automation (EDA) tools
• Working knowledge of RF system concepts (e.g., link budgets, image rejection, frequency planning, and noise-figure cascading).
• Hands-on lab experience with RF measurement equipment (e.g., VNA, spectrum analyzer, signal and function generators, and noise figure meter).
• Strong understanding of 100 MHz -6 GHz communications, mmWave applications and X/Ku-band radar].
• 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 RF/microwave/analog IC focus.
• Experience taking RFIC designs through full tape-out and into high-volume production.
• Familiarity with regulatory and standard compliance (e.g, FCC, 3GPP, MIL-STD).
• Proficiency in Python or MATLAB for simulations and test automation.
• Experience with RF packaging and module integration (e.g., flip-chip bonding, wire bonding, and antenna-in-package (AiP) integration).
• Prior experience in Defense, telecom infrastructure, or consumer wireless
• Existing active security clearance.
