Senior Software Development Engineer of Test; SDET

Driving the Transformation of Software & Quality Engineering Into a Next Generation, AIEnabled Capability Job Summary

The Software Development Engineer of Test (SDET) is a highly technical, senior engineer role responsible for building modern, scalable quality engineering solutions across applications, APIs, and platforms. This role blends software development, SDET level automation, AI enabled testing, and quality architecture to accelerate delivery while improving product reliability. Operating as a technical leader within agile teams, the SDET drives engineering first testing practices, partners with developers to embed testability into design, enhances CI/CD pipeline quality, and advances enterprise automation frameworks.

This role is central to Westfield's transition toward AI accelerated, developer aligned quality engineering—ensuring our teams deliver resilient, high quality software  SDET does not manage people but serves as a technical mentor, influencer, and engineering anchor across the asset delivery team.

Applicants must be currently authorized to work in the United States on a full-time basis without employer sponsorship.

• Design, develop, and maintain robust automated test frameworks for API, UI, integration, performance, and end-to-end testing.
• Write production level automation code using modern languages (e.g., Java, Python, JavaScript/Type Script, C#).
• Implement shift left engineering by partnering with developers on unit testing patterns, code quality, and testability design.
• Ensure automated tests integrate into CI/CD pipelines to improve feedback speed and delivery confidence.
• Identify and automate high value opportunities that replace manual or repetitive validation.
