MetTel is looking for a Software Development Engineer in Test (SDET) to join our QA Operations Testing team in our NYC office!
SDET is not a role where you follow a checklist — we want someone who thinks like an engineer first: someone who digs past symptoms to find root cause, identifies gaps, and builds tools to close them.
AI is changing how software is built and shipped. Development cycles are faster, release frequency is higher, and the complexity of what needs to be validated keeps growing. We need someone who is not just comfortable with that pace, but energized by it — someone who sees a problem and builds the fix before being asked.
ROLE AND RESPONSIBILITIES:
Own quality across the entire SDLC — from requirements and design through development, release, and post-deployment — ensuring every stage meets the bar before moving forward
Drive continuous quality improvement by identifying gaps, raising the bar on standards, and making sure the right checks are in place at every phase
Design, build, and maintain automation frameworks and test suites across functional, API, performance, and regression layers
Investigate and find root cause of failures — then build the right solution, not just a workaround
Integrate AI tools into QA and release workflows to reduce manual effort, improve coverage, and accelerate delivery
Develop release strategies that manage risk in a fast-paced environment — knowing when to ship, when to hold, and using AI to inform that decision
Identify process inefficiencies and build scalable tools or automation to fix them, even outside your immediate scope
Collaborate across engineering, product, and DevOps, communicate risks clearly, and keep stakeholders informed
Write documentation and share knowledge so the whole team moves faster
DESIRED QUALIFICATIONS:
Bachelor's degree or higher in Computer Science, Computer Engineering, or a related technical field
Demonstrated initiative and problem-solving mindset — point to something you built end-to-end that nobody assigned you
Proficiency in one or more programming languages: C#, Java, Python, or JavaScript/TypeScript
Solid foundation in web technologies and REST APIs
Basic SQL knowledge for data validation
Clear communicator — able to explain technical issues to both engineers and non-technical stakeholders
Collaborative team player with a drive to learn, adapt, and grow
Preferred Qualifications:
Experience with modern test automation frameworks such as Playwright, Selenium, or equivalent
Understanding of CI/CD pipelines: Jenkins, GitHub Actions, TeamCity, or Azure DevOps
Experience with or strong interest in AI-assisted testing tools (Copilot, Claude, or similar)
Experience with release management and quality ownership across the SDLC
