PsiQuantum’s mission is to build the first useful quantum computers—machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.
Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.
In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale.
PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact.
Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

Job Summary:
We are seeking an experienced Analog/Mixed-Signal IC Design Engineer to design and deliver high-performance integrated circuits from concept through silicon validation and production. This role spans architecture, circuit design, and lab bring-up, with significant ownership and direct impact on real products.
Responsibilities:
- Design and develop analog and mixed-signal circuit blocks, including:
- Data converters (ADC/DAC)
- Amplifiers (LNA, TIA, op-amps)
- Bandgap references, biasing circuits, and regulators
- Define system architecture and drive trade-offs across noise, linearity, power, area, and bandwidth.
- Perform transistor-level design, simulation, and optimization using industry-standard tools.
- Develop behavioral models (Verilog-A / SystemVerilog RNM) for system-level verification and architectural exploration.
- Work closely with layout to ensure performance through parasitic-aware design and careful floorplanning.
- Run post-layout simulations and sign-off analyses (PVT, Monte Carlo, corner analysis).
- Collaborate with digital and verification teams for robust mixed-signal integration.
- Drive/manage silicon bring-up, debug, and lab characterization.
- Drive clear design documentation and participate in design reviews.
- Take ownership of deliverables and drive work to completion, including under tight timelines.
- Contribute across disciplines as needed, including outside primary specialization.
- Maintain organized workflows to manage simulations, design iterations, and analysis results
Experience/Qualifications:
- MS or PhD in Electrical Engineering or related field.
- Strong fundamentals in analog circuit design and device physics.
- Proven experience designing and taping out analog or mixed-signal ICs.
- Expertise in CMOS or SiGe design across one or more process nodes.
- Proficiency with SPICE-based simulation tools (e.g., Spectre, HSPICE).
- Deep understanding of noise, mismatch, stability, and nonlinearity.
- Ability to design from first principles and solve complex circuit problems creatively.
- Strong organizational skills to manage large design spaces (corners, Monte Carlo, trade-offs).
- Demonstrated ownership mindset with a focus on delivering high-quality result.
Preferred Qualifications:
- Experience with data converters, RF/analog front-ends, or high-speed interfaces.
- Experience with both mature and advanced process nodes (FinFET or beyond) a plus.
- Hands-on experience with silicon validation and lab debugging.
- Experience contributing across full chip development cycles.
- Experience with Cadence Virtuoso design environment.
- Hands-on experience with layout, tapeout, and bench validation.
- Familiarity with SystemVerilog RNM and/or Verilog-A modeling.
What We Value
- First-principles thinking and strong engineering judgment.
- Ability to navigate complex trade-offs across performance, power, and area.
- Ownership from architecture through silicon validation.
- Clear and effective communication in cross-functional teams.
- Intellectual curiosity and a drive to continuously learn new tools, domains, and techniques.
- Flexibility to contribute beyond core responsibilities in a fast-paced environment.
- Strong organizational discipline when working across many design iterations.
- Receptiveness to feedback and commitment to continuous improvement.
- Reliability and accountability in meeting commitments.
- Willingness to go the extra mile to meet critical milestones
