We believe quantum computing will change everything. It will have the power to transform the foundations of giant industries that rely on intensive computation. PsiQuantum is on a mission to build the world’s first useful quantum computer, capable of delivering these transformative results. We know that means it will need 1 million qubits, error correction, a scalable architecture and a data center footprint.

By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.

PsiQuantum is uniquely positioned to deliver on the promise of quantum computing years earlier than our competitors. Our architecture is based on photonics which gives us the ability to produce our components using existing high-volume semiconductor manufacturing processes, the same processes that are today producing billions of chips for telecom and consumer electronics applications. Since photons don’t feel heat, we can take advantage of existing cryogenic cooling systems, the kind that have been operating at facilities like the Stanford Linear Accelerator (SLAC). And because photons are in fact light, they can move between subsystems at tremendous speed using standard fiber connectivity.

Our team is building a utility scale quantum computer and the software tools needed to build fault tolerant quantum applications. We’re a highly motivated and collaborative group focused on a singular goal - building the world’s first useful quantum computer on the fastest path possible.

There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!

Job Summary:

PsiQuantum is singularly focused on the delivery of a useful utility-scale fault tolerant quantum computer. In addition to deploying a world-class quantum computer, we aim to deliver a world-class quantum user experience to both our external customers and internal developers. This will require the development of a novel, production-grade software system which will enable the delivery of both external enterprise products and internal quantum toolchains to interact with multiple generations of our system.

We are seeking an experienced Software Development Engineer in Test (SDET) to join our team, bringing a strong background in testing and automation, particularly in quantum-related software. This role demands a professional who is comfortable working with complex systems and can drive the development and implementation of advanced testing frameworks. The ideal candidate will have a solid background in testing quantum circuits, integration testing, and system engineering, and a proven ability to ensure software quality in a fast-paced environment. Experience with CI/CD pipelines, test automation, and debugging is essential, as is a strong understanding of both frontend and backend testing methodologies.

In addition to the required technical skills, familiarity with quantum software tools, performance optimization, and data validation will be highly valued as we continue to enhance our software testing strategies. This role will also provide the opportunity to shape and grow a team, contribute to innovative testing solutions, and drive critical testing projects that are crucial to our success.

If you are someone who enjoys leading testing initiatives and ensuring the reliability of complex software systems, we would love to hear from you.

Responsibilities:

• Design and implement test automation frameworks focused on testing/validating quantum software, including integration and functional testing.
• Lead the testing efforts across various teams using reproducible testing frameworks such as Robot and Jira X-ray.
• Verify and validate quantum software, packages, and programs according to design specifications and product requirements.
• Collaborate with the product and development teams to develop comprehensive test plans and execute them based on jointly defined acceptance criteria.
• Build and implement monitoring tools to detect data integrity issues and ensure nightly jobs run smoothly on CI/CD pipeline.
• Oversee the integration of independently developed software components, ensuring compatibility and stability across packages while ensuring that the developed tests remain and are updated with the new features
• Collaborate with the development team to enhance the exception handling and error logging mechanisms used in production software.
• Drive continuous improvement in testing methodologies and software quality, integrating advanced testing methods into CI/CD pipelines.
• Design, implement and run end-to-end system tests, and build monitoring tools for detecting changes in test coverage over time.
• Troubleshoot integration issues and document common problems using root cause analysis.
• Work with developers, end-users, and management to address issues and improve testing strategies.

Experience/Qualifications:

• Degree in Computer Science and/or visual/graphic design or equivalent experience.
• Proven track record in testing complex software systems, particularly in quantum computing or related fields.
• 4+ years of experience in test automation, system integration testing, and performance optimization.
• Experience with CI/CD pipelines, test automation tools, and debugging in complex software ecosystems.
• Strong background in testing both frontend and backend components, with a focus on data validation and output verification.
• Familiarity with quantum software tools and frameworks and experience in developing benchmarks and reference datasets.
• Demonstrated verbal, written, and presentation skills.
• Proven ability to work effectively across departments, sites, and time zones.
• A problem solver with an analytical mindset, capable of troubleshooting complex integration issues.
• Ability to work independently and contribute to a fast-moving, innovative environment.
