• Establish and maintain software baselines and visibility into code assets across programs
• Define and analyze engineering metrics (e.g., code coverage, complexity, language composition) to guide improvements
• Improve the developer experience through better tools, workflows, and practices
• Partner with teams to standardize and modernize software approaches across programs
• Evaluate and introduce new technologies and approaches, scaling what works

Basic Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related field with 8+ years of relevant experience. Additional years of experience may be used in lieu of a degree.
