Lead Software Test Engineer

Cox Automotive Inc.
Exton, PA Full Time
POSTED ON 5/13/2026
AVAILABLE BEFORE 6/11/2026
Job Description

The Lead Software Test Engineer applies advanced knowledge of testing principles, methodologies, and techniques to ensure the quality and reliability of complex, distributed software platforms. Serving as an influential participant in design reviews, this role develops and executes functional, integration, system, load, and performance tests; defines system-wide standards for test automation; and coordinates cross-organizational UAT environments in partnership with integrating teams. This role applies effective influence and collaboration-without formal management authority-across Engineering, Product, Architecture, and SRE to embed quality throughout the software delivery lifecycle.

The Lead STE takes the lead on difficult defect detection and troubleshooting, predicts and documents potential risks and constraints, and leverages AI tooling to drive consistency in test automation across the engineering organization. As engineering teams increasingly rely on AI-generated code, the Lead STE serves as a thought leader in evolving quality practices to meet this shift - defining how TDD requirements, code complexity standards, and test coverage thresholds are embedded directly into AI coding agent configurations, ensuring quality is enforced at the point of generation rather than discovered after the fact.

Primary Duties And Key Responsibilities

  • Governs system-level test case libraries end-to-end: sets coverage standards, identifies gaps, and drives closure with engineering and product teams.
  • Defines technical standards and reference implementations for test automation at the API, integration, and system end-to-end layers.
  • Coordinates with integrating customers to establish and maintain cross-organization test cases and automation in UAT network of environments.
  • Identifies teams with test coverage or automation gaps and embeds to lead remediation - coaching on patterns, driving script development, and verifying quality gate criteria are met before release.
  • Drives adoption of quality standards within AI agent configurations across engineering teams, ensuring TDD practices, code complexity standards, and test coverage requirements are codified in team project files rather than applied as post-generation checks. Defines system-wide scenarios for load, stress and soak testing.
  • Designs and operates shared test execution infrastructure that enables functional and non-functional test suites to run consistently across CI/CD pipelines, scheduled cadences, and multiple environments - reducing manual effort and accelerating quality feedback loops.
  • Partners with SRE to design Game Day scenarios that validate system resilience under failure conditions, translating reliability risks and SLO targets into executable test cases.

Required Experience, Knowledge, And Skills

  • Bachelor's degree in a related discipline and 6 years of experience in a related field, or equivalent combinations such as a master's degree and up to 4 years of experience, or 10 years of experience with no degree.
  • Hands-on experience developing test automation with modern frameworks such as Playwright, RestSharp, Pact.NET, and xUnit.
  • Hands-on experience creating performance test automation with tools such as JMeter or k6.
  • Experience with test management and orchestration (test reporting frameworks, TestContainers, etc.).
  • Reviews product requirements and system designs with a testability lens, contributing test strategy input during architecture reviews and driving implementation patterns that support maintainable, scalable automation.
  • Skilled at building partnership with Product, Architecture, and Engineering teams both inside and outside of the organization.
  • Remains current on test automation tooling and methodologies, recommending and driving adoption of advanced approaches that measurably improve coverage, defect detection, or CI/CD feedback cycle times.
  • Demonstrated experience working with AI coding tools (such as Claude, GitHub Copilot, or equivalent) and the ability to define and implement quality guardrails within agent configurations, constitutions, or briefings
