Job Details

Toshiba Global Commerce Solutions is seeking a Non-Functional Test Lead to drive quality and performance validation across mission-critical retail software solutions. This role will focus on performance, load, stress, and scalability testing to ensure our systems can scale reliably, maintain high availability, and deliver optimal performance under real-world retail conditions. Experience in security, usability, or compatibility testing is a plus.

As a key member of the quality engineering team, you'll work closely with architects, developers, and product managers to design and execute test strategies that validate non-functional requirements across complex integrated systems.

This is a billable, U.S.-based, customer-facing consultancy role-frequently onsite at client locations. The ideal candidate will act as a trusted advisor to enterprise customers, demonstrating and simulating NFT capabilities in their environments, identifying additional areas for optimization, and helping expand the adoption of our NFT services. This is a highly technical position that also plays a key role in supporting revenue growth through solution consultation and strategic influence.

• Lead the planning, design, and execution of performance, load, stress, and scalability tests for enterprise retail software and systems.
• Define test scenarios, benchmarks, and success criteria based on business SLAs and architectural specifications.
• Develop test scripts, simulate virtual user load, and analyze system behavior under varied conditions.
• Collaborate with cross-functional teams to identify bottlenecks and optimize system performance.
• Utilize observability and APM tools (e.g., Datadog, New Relic, Dynatrace) to monitor system behavior and diagnose performance bottlenecks.
• Conduct resiliency and chaos testing to validate system stability under failure conditions.
• Design and implement performance tests for microservices and distributed systems, including in cloud-native environments (AWS, Azure, GCP).
• Contribute to test automation pipelines and continuous performance testing integration.

• Strong scripting skills (Python, Bash, PowerShell) and hands-on experience with automation and CI/CD frameworks (e.g., Jenkins, GitLab CI).
• Strong communication skills and ability to translate performance findings into actionable recommendations.

• Exposure to security testing tools and methodologies (e.g., OWASP, penetration testing basics).
• Experience in usability testing and user behavior analysis.
• Knowledge of cross-browser and platform compatibility testing.
• Understanding of Site Reliability Engineering (SRE) practices and performance SLAs.
