Senior Software QA Engineer, PsiQuantum

• We are seeking an experienced Senior Software Quality Assurance (QA) Engineer with a robust background in full-stack enterprise QA, automation frameworks, CI/CD, and QA strategy definition
• 8+ years in QA experience: Experience in hands-on manual testing and test automation development with frameworks like Selenium, Cypress, or Playwright
• 4+ Years in QA Leadership: Demonstrable experience leading QA teams in full-stack, highly technical environments, ideally spanning front-end, back-end, and infrastructure layers
• Proven QA Strategy & Automation Track Record: A history of establishing scalable QA processes, implementing test automation frameworks, and integrating QA in CI/CD pipelines
• Mentorship & Collaboration: Demonstrated success mentoring or training cross-disciplinary teams, with the ability to translate classical QA methods into domain-specific contexts
• Software Engineering Foundations: Solid understanding of software engineering principles (OOP, version control, branching strategies) and proficiency in scripting languages (e.g., Python)
• Front-End & Back-End Testing: Experience testing web UIs, REST APIs, microservices, data validation, and output verification
• Complex Systems & R&D: Comfort operating in a research-oriented or emerging technology setting, adapting QA processes to novel and sometimes ambiguous requirements
• Bachelor’s Degree: In Computer Science, Engineering, or a related field

Desirable

• PsiQuantum’s Quantum Applications Software Team 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
• This role will establish QA processes, conduct QA activities, define quality metrics, and mentor team members—including those with deep quantum domain knowledge but limited QA specialization—ultimately laying the foundation for a dedicated quantum QA group
• This role bridges classical QA expertise with cutting-edge quantum development, creating a new paradigm for testing hybrid software systems
• You’ll pioneer QA practices for quantum applications while upskilling domain experts, shaping the future of quantum software reliability
• This is a hands-on technical leadership role; you’ll split time between coding/testing frameworks (e.g. , Selenium, Xray) and mentoring developers
• You’ll personally build foundational test infrastructure while scaling the team’s QA capabilities
• Lead the testing efforts and design and implementation of QA processes and best practices that align classical enterprise-level rigor with the unique challenges of emerging quantum software
• Train and mentor developers and engineers from a quantum background in QA methodologies, helping them adopt industry-leading testing strategies
• Drive both the tactical (hands-on test framework development) and strategic (quality metrics, team building, process definition) aspects of QA in a rapidly evolving, R&D-focused environment
• Hands-On Framework Development: Design and implement test automation suites (using tools like Pytest, Selenium, Robot, etc.) to achieve reliability, maintainability, and reproducibility across software interfaces
• Test Development: Write and maintain automated test scripts (e.g., Selenium for UI, Pytest for APIs, Xray for test management) while guiding others to adopt these frameworks
• Cross-Functional Collaboration: Work with product, DevOps, and quantum domain experts to develop integration, functional, and system tests in a highly technical environment—potentially involving HPC or containerized infrastructure
• Establish Comprehensive QA Processes: Develop QA frameworks tailored to hybrid classical-quantum software systems, including defining key quality metrics (e.g., defect density, coverage, mean time to detect/fix)
• Integrate QA in CI/CD: Embed QA best practices into automated pipelines, ensuring seamless testing, monitoring, and reporting
• Knowledge Transfer: Serve as the QA subject matter expert, training quantum software developers on testing strategies and concepts (e.g., regression testing, test hierarchies) , defect management, and continuous improvement processes
• Team Leadership: Oversee the gradual formation of a quantum QA group, defining roles and responsibilities to scale as the team grows
• Cultural Leadership: Foster a ‘quality-first’ culture by coaching quantum developers on risk assessment, test case design, and defect prioritization in R&D environments
• Performance & Scalability: Define performance benchmarks, stress-testing protocols, and scalability testing strategies for large-scale or domain-specific workloads (quantum simulations, HPC, etc.)
• System End-to-End Testing: Implement comprehensive testing frameworks that validate the entire software ecosystem, from front-end interfaces to back-end computational layers
• Iterative Development: Collaborate with developers and product managers in Agile or iterative environments, refining test plans and acceptance criteria each sprint
• Quality Metrics & Monitoring: Establish feedback loops, collect QA metrics, and conduct root-cause analyses to evolve testing processes continuously
