Software Development Engineer in Test (SDET)

Parking isn’t just about spaces – it’s about creating seamless experiences, sustainable solutions, and smarter cities. At Flash, we’re not just thinking about today’s parking challenges; we’re actively shaping the future of parking + charging. Join us in transforming the way the world parks.

Flash is seeking a highly skilled and motivated SDET to build scalable automated testing solutions that ensure high-quality software delivery. The SDET is an engineer first—responsible for designing, developing, and maintaining automated test frameworks, integrating quality into CI/CD pipelines, and partnering with development teams to prevent defects early in the software lifecycle.

This is not a traditional QA or automation role. We are seeking an engineer-first SDET who can design and build testing frameworks from the ground up, operate at the code level, and integrate quality deeply into the development lifecycle. You will work across the stack—UI, API, and database layers—to ensure scalable, high-quality software delivery.

This is a high-impact role with direct influence on product quality and engineering practices. You’ll have the opportunity to modernize legacy frameworks, introduce new technologies, and shape testing strategy and tools from the ground up. Working with cutting-edge tools—including AI-assisted development—you’ll be empowered to innovate, experiment, and drive meaningful change across the organization.

• →Design and build automated test frameworks and tools from scratch
• →Develop and execute automated tests across UI, API, and database layers
• →Integrate automated testing into CI/CD pipelines (GitHub Actions, Jenkins)
• →Partner closely with Engineering, Product, and QE teams to define test strategies and improve quality early in the development cycle
• →Review code and provide feedback to ensure testability and quality standards
• →Identify defects, troubleshoot root causes, and collaborate on solutions
• →Build and manage test environments, test data, and supporting infrastructure
• →Contribute to performance and security testing efforts
• →Leverage AI tools (e.g., GitHub Copilot, Gemini CLI) to improve development and testing efficiency
• →Continuously evaluate and introduce new tools, frameworks, and best practices
