Senior Software QA Engineer

Psi Quantum'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 Global Foundries— 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, Psi Quantum 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.

Psi Quantum 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.

Psi Quantum’s Applications Software Engineering Team (ASET) is dedicated to creating a software environment where quantum application developers can discover, build, utilize, optimize, and visualize large‑scale quantum algorithms for classically intractable problems. As we continue to scale, we’re building out a QA function that bridges classical software QA best practices with cutting‑edge quantum software development.

We are seeking a Senior Software Quality Assurance (QA) Engineer with strong technical skills and business awareness to establish our test automation practice. You’ll take our Playwright‑based testing PoC to production, building frameworks and tooling that enable our development teams to own quality long‑term.

This is a hands‑on IC role reporting to the Director of Engineering, working across our Application Software Engineering Team (ASET) which includes our Construct platform crew and REx module crew. You’ll spend 80 % of your time building test automation infrastructure and frameworks, and 20 % coordinating testing efforts, triaging results, and providing quality metrics to leadership. You’ll work autonomously, influence without authority, and have significant impact on our product quality as we approach our general availability launch.

Test Automation and Integration Frameworks

• Test Framework & Infrastructure:
Design and build test automation frameworks (using tools like pytest, Playwright, Robot) that enable developers to own and maintain their own tests. Focus on creating scalable, maintainable infrastructure rather than writing every test yourself—think framework builder, not test author.

• Test Development Mentor:
Write initial automated test scripts (e.g., Playwright for UI, pytest for APIs) that demonstrate best practices and serve as templates for developers to follow. These examples help others adopt the frameworks you build, but you won’t be writing all tests long‑term.

• Rapid Implementation:
Take existing test automation PoCs to production‑ready CI/CD integration within the first 60 days, delivering automated critical user journeys with clear reporting and retry logic.

• Cross‑Functional
