• Lead the modernization of a large-scale embedded software test system.
• Define and modernize a standardized, fully automated, headless framework across virtual and physical environments to enable full-suite testing multiple times per day.

Key Deliverables

• Define the architecture and roadmap for standardized test execution, configuration and variation management, traceability, quality gates, regression selection, and results reporting.
• Establish change-impact analysis and risk-based regression strategies using Gears, Pure Variants, or equivalent tools to determine test applicability and optimize re-testing.
• Standardize test-result schemas, metadata, diagnostics, and artifacts; enable storage in Databricks for analytics, trend analysis, data mining, and reporting.
• Develop APIs and integrations connecting test execution, test management, issue tracking, failure triage, and diagnostic tools
• Improve test robustness, failure triage, execution speed, and deployment efficiency across CI/CD pipelines and physical and virtual test environments.

Measures of Success

• Faster, more reliable test deployment and execution.
• More efficient regression testing through accurate change-impact analysis.
• Standardized, traceable test results accessible through Databricks and documented APIs.
• Faster failure identification, triage, and resolution.
• Clear test applicability across software, hardware, configuration, and platform variants.

Qualifications/Requirements

• Bachelor's degree in computer science, computer engineering, electrical engineering, software engineering, systems engineering or a related technical field; or equivalent practical experience.
• Typically, 10+ and 15+ more years experience validating software systems, including substantial experience leading architecture across organizations.
• Deep understanding of software architecture for real time systems.
• Experience shipping high quality safety critical products.
• Experience architecting large-scale CI/CD, embedded test automation, and build-to-test pipelines.
• Expertise in variation management, configuration comparison, change-impact analysis, and risk-based regression testing.
• Experience with test-result data modeling, Databricks, analytics, data mining, and API development.
• Proficiency with embedded systems, Linux, Git, Python, Bash, Robot Framework, containers, and infrastructure as code.
