Job description

Job Title: Senior SDET – Trade Management
Location: Westlake, TX (On-site)
Employment Type: Contract (W2 through ZipStaff)

About the Opportunity
ZipStaff is seeking a Senior SDET to architect and build a new common automation platform for a leading financial services organization in Westlake, TX.

You will deliver a unified, scalable end-to-end automation engine supporting 13+ modernization teams. This is a greenfield framework role covering UI and API automation for institutional trade and order-management workflows — not a manual QA or script-maintenance role.

What You’ll Do:
  • Architect and build a brand-new unified Java and TypeScript automation platform from the ground up.
  • Support both UI automation (Playwright / Selenium) and API testing across 13+ teams.
  • Establish modern CI/CD patterns in Jenkins and use GitHub Copilot to accelerate framework construction and test authoring.
  • Automate core order-lifecycle workflows: Create → Modify → Cancel → Execute.
  • Validate institutional OMS order rules, post-trade processing, downstream clearing/settlement integrations, and regulatory reporting platforms.
  • Design and execute API-driven automated tests (REST / SOAP) for workflows routed through Director-pattern architectures.
  • Perform state comparison and data validation across coexisting legacy systems (Mainframe / DB2 via SOAP) and modern cloud / microservice platforms.
  • Enhance test reporting dashboards for coverage, execution stability, and business-capability regression metrics across trading areas.

Required Qualifications:
  • 7–8+ years of hands-on test automation / SDET experience, including framework design (not script-only backgrounds).
  • Strong programming skills in Java and TypeScript.
  • Advanced experience with Playwright and/or Selenium for UI automation.
  • Hands-on API automation with REST and SOAP, including Cucumber / BDD.
  • Experience building or modernizing a shared automation platform used by multiple teams.
  • Hands-on Jenkins CI/CD experience.
  • Experience using GitHub Copilot (or similar) in a daily engineering workflow.
  • Ability to work on-site in Westlake, TX.
  • Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:
  • Institutional trading, OMS, order lifecycle, post-trade, clearing/settlement, or regulatory reporting experience.
  • Experience validating across legacy mainframe / DB2 SOAP services and modern microservices.
  • Experience with test reporting dashboards and quality metrics at scale.

About ZipStaff
ZipStaff partners with leading organizations to connect skilled technology professionals with high-impact contract opportunities. We focus on quality matches and long-term success.

To apply, please submit your resume highlighting your Java/TypeScript automation framework work, Playwright/API testing, and any trade/order-management domain experience.
