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
