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:

  • Demonstrated experience integrating automated validation into CI/CD pipelines to support continuous delivery and reliable release workflows
  • Proficiency using Git-based version control workflows and collaborating through issue tracking systems such as Jira or similar platforms
  • Experience working across the full software development lifecycle within Agile development environments, collaborating closely with developers and product teams
  • Strong debugging and analytical skills, including the ability to investigate complex failures and identify root causes in distributed systems
  • Excellent communication, collaboration, and technical documentation skills

Preferred Experience:

  • Hands-on experience developing automated tests using modern web automation frameworks such as Playwright, Cypress, or Selenium
  • Practical experience validating cloud-hosted services or applications deployed on AWS, GCP, or Azure
  • Working knowledge of containerized development environments, including running applications or automated tests using Docker
  • Experience validating data pipelines or data platforms, including validating structured data used by services or analytics workflows
  • Experience using observability or monitoring platforms (e.g., logs, metrics, tracing) to troubleshoot failures and analyze system behavior
  • Demonstrated use of Generative AI tools to improve development or testing workflows, such as generating test cases, debugging assistance, or documentation
  • Experience developing or executing simulation-based validation scenarios in virtual environments to support system-level testing

Things that make a difference:

  • Master’s degree in Computer Science, CE, EE
  • Experience validating machine learning systems or ML-enabled applications, including model inference services, training data pipelines, or model output validation
  • Experience with NVIDIA Isaac Sim or similar robotics simulation platforms
  • Experience working in environments that combine cloud services, mobile applications, and data platforms
  • Experience in mobile robotics or industrial automation is a plus
  • Experience with common sensors used in robotics, including cameras (RGB and Depth), LIDARs, IMUs and Sonars is a plus
