## Description

As an Software Development Engineer in Test, you operate at the intersection of software development and quality engineering. You design and build high-quality test infrastructure and automation in the same way developers build production systems. With your strong programming skills in C++and/or Python, you ensure software is testable, scalable, and reliable by design. You work closely with software engineers on complex high-tech systems, contributing directly to codebases, test architecture, and continuous integration pipelines. Rather than only validating software, you actively shape how it is built and verified., * Design, develop, and maintain test frameworks and automation tooling using C++ and/or Python

 * Contribute to production code and testability improvements in collaboration with software engineers
 * Develop automated tests across multiple levels (unit, integration, system) as part of the development process
 * Build and optimize CI/CD pipelines and test infrastructure to enable fast and reliable feedback
 * Analyze complex systems and failures, and trace issues to root cause in code
 * Drive testability, observability, and quality-by-design principles within development teams
 * Work on high-tech systems (embedded / hardware-software integration / distributed systems) with real-world impact
 * Take ownership of technical decisions around test architecture and tooling
 * Continuously improve automation strategy with a strong focus on engineering scalability and maintainability
