Software Development Engineer in Test (SDET)

Role Overview

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, regression, and risk-based manual testing.
• Review requirements and acceptance criteria for gaps, edge cases, risks, and testability.
• Collaborate 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.
• 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 and must independently review generated output for correctness, security, maintainability, test value, and alignment with established standards.

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.

Workplace Requirements

• Must be local to Lansing, Michigan for onsite reviews 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 onsite required.
• Please No C2C or 3rd Party Submissions.
