Postdoctoral Semiconductor information

What is a postdoctoral semiconductor?

Postdoctoral Semiconductor positions are research roles offered to individuals who have recently completed their Ph.D. in fields related to semiconductor physics, materials science, electrical engineering, or similar disciplines. These positions typically focus on conducting advanced research in the design, fabrication, and characterization of semiconductor materials and devices. Postdocs in this field work in academic, government, or industry labs, collaborating with other scientists and engineers to push the boundaries of semiconductor technology. The role is usually temporary, lasting two to three years, and aims to further develop specialized expertise before pursuing a permanent academic or industry position.

What are the typical research responsibilities and collaborative opportunities for a postdoctoral semiconductor researcher?

As a Postdoctoral Semiconductor researcher, your daily responsibilities often include designing and conducting experiments, analyzing data, and publishing results in peer-reviewed journals. You will likely work closely with multidisciplinary teams, including faculty members, Ph.D. students, and industry partners, to advance semiconductor technology. Collaborative opportunities are abundant, as projects frequently involve partnerships with national laboratories or private companies, providing valuable exposure to both academic and applied research environments. This role also offers the chance to mentor junior researchers and expand your professional network within the semiconductor field.

What are the key skills and qualifications needed to thrive as a postdoctoral semiconductor researcher, and why are they important?

To thrive as a Postdoctoral Semiconductor Researcher, you need a PhD in physics, electrical engineering, materials science, or a related field, with a strong background in semiconductor devices and materials. Expertise in cleanroom processes, semiconductor fabrication tools, advanced characterization techniques, and simulation software is typically required. Strong analytical thinking, problem-solving skills, and effective communication help drive collaboration and innovation in research teams. These skills ensure high-quality research outcomes, the ability to tackle complex technical challenges, and contribute valuable advancements to the semiconductor field.

Computer and Peripheral Equipment Manufacturing • 51 - 200 employees

$122K - $168K/yr

Full-time

Re-posted 8 days ago


Key responsibilities

  • Design, simulate, and optimize integrated photonic devices and circuits for quantum computing.

  • Lead photonic tapeouts, including layout, design, planning, and stakeholder interfacing.

  • Collaborate with test and lab teams to plan, execute, and develop automated high-volume tests and analysis methods.


Job description

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. 

Come join us.
