The ideal candidate brings strong debugging skills, hands-on coding proficiency, and the ability to own production incidents end-to-end while also contributing to UI, API, and full-stack testing.
This position does not require building automation frameworks from scratch, but it does require professional-level coding skills to debug application code effectively and support existing automation.
Key Responsibilities: Will need 8+ years of experience in the following:
Application Support & Production Ownership (50%)
- Own all production incidents, including triage, RCA- Root Cause Analysis, and coordination with development teams.
- Perform L2 Application/Production Support for critical applications; incidents may occur at any time.
- Debug application code (C#, .NET Core, React, TypeScript) to identify root cause and provide detailed findings to developers.
- Monitor applications using Azure Monitor and App Insights.
- Participate in minimal on-call rotation.
- Delegate incident tasks to other teams when appropriate.
- Support batch systems, performance issues, security concerns, and integration failures.
- Cross functional collaboration to ensure stability across Dev, QA, UAT, and Prod environments.
Testing & QA Automation (50%)
- Execute and maintain automation using Selenium and Playwright (no framework building required).
- Perform Web Site / Web Application Testing across frontend and back-end components.
- Perform Testing for UI, API, full-stack, database, integration, batch, performance, and security.
- Write and debug automation code as needed to support testing activities.
- Work as part of the team on performance, security, and integration testing (shared ownership).
- Use AI tools (Copilot, Claude) to accelerate testing and debugging workflows.
Release, Deployment & CI/CD
- Own and perform application deployments.
- Run CI/CD pipelines and deploy code; triage pipeline issues and collaborate with developers to resolve them.
- Validate releases in lower environments as part of sprint work.
Required Technical Skills
- Professional-level coding in C#, .NET Core, TypeScript, and React (required for deep debugging).
- Strong experience with Selenium and Playwright.
- Hands-on experience with Azure, including Azure Monitor and App Insights.
- Solid understanding of CI/CD pipelines (running builds, deployments, basic triage).
- Strong SQL skills for database testing and investigation.
- Familiarity with AI code-generation tools (Copilot, Claude).
Required Soft Skills
- Excellent communication and cross-functional collaboration.
- Strong problem-solving and analytical thinking.
- Ability to triage complex issues quickly and accurately.
- Ability to work proactively (quality improvements) and reactively (incident response).
- Strong ownership mindset and ability to manage high-impact production issues.
What Makes This Role Unique
- True 50/50 hybrid: Senior in both SDET and L2 support.
- Hands-on coding required, but no framework building.
- Owns deployments and production incidents, not just testing.
- Full-stack testing across UI, API, database, batch, performance, and security.
- High visibility role with direct impact on production stability and product quality.
