Software Development Engineer in Test (SDET)

Job description

Must be local to Lansing, Michigan for on-site interviews and on-site work requirements. This job's duties may include task assignments to support, administer, or access systems, which contractually require ADP I or II clearance and U.S. Citizenship or naturalized citizen. No remote option. 4 days working on-site required. Please No C2C or 3rd Party Submissions. Summary This hands-on quality engineering position combines Playwright automation, API testing, SQL validation, exploratory testing, and targeted manual testing. Candidates must be capable of writing maintainable TypeScript and contributing to automation architecture - not simply recording or modifying test scripts. Our primary tools include Playwright with TypeScript, GitHub Copilot, Jenkins, Bitbucket, and Oracle. Key Responsibilities Develop and maintain UI and API automated tests using Playwright and TypeScript. Expand the existing Playwright framework and establish reusable fixtures, API clients, utilities, and coding standards. Create automated coverage for Angular applications and Java based REST APIs. Integrate and execute automated tests through Jenkins. Investigate failures using Playwright traces, application logs, network activity, API responses, and SQL. Validate application processing and data using Oracle SQL. Perform exploratory, functional, integration, recession, and risk-based manual testing. Review requirements and acceptance criteria for gaps, edge cases, risks, and testability. Collaborative with developers, product owners, and testers throughout story development. Participate in code reviews and improve the reliability and maintainability of the automation suite. Identify flake, redundant, slow, or low-value tests and address their underlying causes. AI - Assisted Quality Engineering SDETs are expected to use GitHub Copilot and other approved AI capabilities in their daily work to improve speed, coverage, and effectiveness. This includes: Generating and refining Playwright TypeScript tests for UI and API scenarios. Identifying missing scenarios, edge cases, negative paths, and requirement gaps. Accelerating test-data creation, SQL queries, API requests, and reusable automation components. Analyzing failures, logs, stack traces, and Playwright traces. Refactoring repetitive, flaky, or difficult-to-maintain automation code. Creating technical documentation, test summaries, and defect details. Understanding unfamiliar application code and identifying areas of testing risk. Sharing effective AI-assisted testing practices with other team members. SDETs remain accountable for all AI-generated work. Candidates must independently review generated output for correctness, security, maintainability, test value, and alignment with established standards. AI-generated code must not be accepted simply because it compiles or passes once. Required Qualifications Hands-on experience using Playwright with TypeScript for UI and API automation. Strong TypeScript programming fundamentals. Experience designing maintainable automation—not simply creating test scripts. Experience testing modern web applications, preferably Angular. Experience testing Java-based REST APIs. Strong understanding of HTTP, REST, JSON, authentication, response validation, and negative API testing. SQL experience for backend data validation, preferably with Oracle. Experience executing automated tests through Jenkins or another CI/CD platform. Experience with Git-based source control and collaborative development workflows. Ability to diagnose failures across the UI, API, database, test code, test data, and environment layers. Experience with exploratory and manual testing in addition to automation. Ability to work independently and communicate defects and quality risks clearly.
