Position Overview:

The Senior Software Development Engineer in Test (Sr. SDET) is a software engineer responsible for designing and implementing automated validation systems that ensure the reliability and quality of software applications and services.

Working closely with product developers, platform engineers, and quality teams, the Senior SDET builds automation frameworks, validation tools, and testing strategies that support reliable releases across web applications, cloud services, mobile platforms, and supporting data systems.

Unlike traditional QA roles, the Senior SDET contributes code alongside development teams and plays a key role in improving testing practices, automation coverage, and CI/CD workflows. This role also provides technical guidance to other engineers and helps drive improvements in quality engineering practices across the team.

Essential Job Functions:

Automation Development & Test Engineering

• Design and implement automated testing solutions for web applications, APIs, backend services, and supporting systems
• Develop and maintain test automation frameworks and validation tools using Python in Linux-based environments
• Create automated tests for functional, integration, and regression validation of software systems
• Define and implement testing strategies for features and services within a product area
• Contribute to the improvement of automation frameworks, testing infrastructure, and engineering tooling

Simulation-Based Validation

• Develop complex simulation scenarios that replicate real-world environments and edge cases to support system validation and regression testing
• Collaborate with engineering teams to integrate simulation-based testing using tools such as NVIDIA Isaac Sim into automated testing workflows

CI/CD & Engineering Workflow Integration

• Integrate automated validation into CI/CD pipelines to support reliable and efficient release processes
• Collaborate with product developers to ensure systems are testable, observable, and reliable
• Participate in architecture discussions and design reviews to ensure new systems can be effectively validated

Quality Insights & Reporting

• Investigate complex test failures, analyze system behavior, and support root cause analysis with engineering teams
• Develop and maintain quality dashboards and reporting tools that provide insight into product health and system reliability
• Help ensure traceability between requirements, implementation, and validation activities

Engineering Documentation & Collaboration

• Collaborate with cross-functional teams to ensure clear requirements, acceptance criteria, and validation strategies
• Document validation approaches, testing strategies, and key findings to support engineering teams and product development

AI-Assisted Development & Testing

• Apply Generative AI (GenAI) tools to improve software development workflows, test generation, debugging, and engineering productivity
• Contribute to efforts that incorporate GenAI capabilities into development or product features where applicable

Technical Leadership & Mentorship

• Mentor SDET I and SDET II engineers on automation practices, debugging, and software engineering techniques
• Provide technical guidance to team members and help promote modern quality engineering practices across the team

Education and/or Work Experience Requirements: 

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineeri
