Senior Software QA Engineer

Senior Software QA Engineer – Psi Quantum

Psi Quantum is on a mission to build the first real, useful quantum computers. The company focuses on silicon photonics‑based quantum hardware and aims to deliver large‑scale quantum algorithms for industry‑transforming applications.

The Applications Software Engineering Team (ASET) creates a software environment for quantum application developers. A growing QA function bridges classical QA best practices with cutting‑edge quantum software development.

You will be a hands‑on IC Senior QA Engineer, reporting to the Director of Engineering. Your primary responsibilities are 80% building test automation infrastructure and frameworks, and 20% coordinating testing efforts, triaging results, and reporting quality metrics.

• Design and build scalable test automation frameworks using pytest, Playwright, and Robot.
• Write initial automated test scripts (UI, API) to demonstrate best practices and serve as templates.
• Deliver production‑ready CI/CD integration of PoCs within the first 60 days.
• Collaborate with product, platform engineers, and domain experts to develop integration, functional, and system tests.
• Define and enhance QA strategy, processes, and metrics such as defect density and coverage.
• Integrate test automation into Git Lab CI/CD pipelines, ensuring clear reporting.
• Define performance benchmarks and stress‑testing protocols for large‑scale workloads.
• Build end‑to‑end system tests for front‑end, back‑end, and computational layers.
• Partner with teams following agile practices, improving quality through iterative development.
• Coordinate across multiple product teams, balancing priorities and delivering value.
• Generate executive‑level quality reports and dashboards.

• 8+ years in QA, including manual testing and test automation with Selenium, Cypress, or Playwright.
• 4+ years as a Senior QA Engineer or QA Lead in full‑stack, highly technical environments.
• Proven track record of building scalable QA processes and integrating automation into CI/CD pipelines.
• Experience collaborating with cross‑disciplinary teams and translating classical testing methods into domain‑specific contexts.
• Solid understanding of software engineering fundamentals (OOP, version control, branching) and proficiency in scripting languages such as Python.
• Front‑end and back‑end testing experience (web UIs, REST APIs, microservices, data validation).
• Comfort operating in research‑oriented or emerging technology environments.
• Bachelor’s degree in Computer Science, Engineering, or related field.

• Quantum domain exposure (Qiskit, Cirq, or similar).
• AI‑driven test automation experience (Applitools, Testim.io, Sealights).
• Startup or early‑stage experience, rapidly moving from PoC to production.
• HPC or large‑scale testing experience (Docker/Kubernetes, performance testing).
• Agile/Scrum and Dev Ops experience (Git Lab, Git Hub Actions, cloud testing).
