Software Development Engineer in Test (SDET)

What you will do

• Design, develop, and maintain scalable Python-based test automation frameworks and reusable test libraries for API, UI, system, functional, regression, and performance testing. • Apply software engineering best practices, including SOLID principles, design patterns, clean code standards, and TDD/BDD methodologies, to ensure maintainable and reliable test solutions. • Develop automated test strategies for distributed and embedded systems, including mocking, stubbing, network performance validation, and basic security testing. • Troubleshoot complex test failures, refactor legacy automation, and drive continuous improvements in test quality, reliability, and execution efficiency. • Integrate and optimize automated testing within CI/CD pipelines to enable scalable, parallelized, and automated regression testing. • Create and review test plans, procedures, reports, and quality documentation to support compliance, traceability, and product validation requirements. • Collaborate with Software Development, DevOps, Systems Engineering, and QA teams to improve testability and promote shift-left testing practices. • Lead code reviews, mentor junior SDETs, and drive adoption of testing best practices, tools, and emerging technologies. • Ensure test activities align with regulatory, defense, and naval industry quality standards while performing hands-on and exploratory testing as required.
• What you will bring:
• Degree or diploma in Computer Science, Software Engineering, or a related field, or an equivalent combination of education and experience. • 8+ years of software testing and test automation experience, including 5+ years of Python development. • Strong knowledge of software testing methodologies, automation frameworks, software development lifecycles, Agile practices (Scrum/Kanban), and CI/CD pipelines. • Experience testing distributed, networked, real-time, or embedded systems, with strong troubleshooting and problem-solving skills. • Proficiency in software design principles, including SOLID, design patterns, version control systems (Git/SVN), and test and issue management tools (e.g., Jira, Zephyr Scale). • Demonstrated leadership experience mentoring team members, conducting technical reviews, and making sound technical decisions. • Excellent written and verbal communication skills, with the ability to convey technical concepts to both technical and non-technical stakeholders. • Familiarity with AI-assisted development and testing tools is an asset. • Experience in defense, naval, safety-critical, or regulated software environments is preferred.
