• Lead the adoption ofAI-assisted engineering practicesto improve developer productivity, including code generation, testing, and development workflows

• Identify and implement opportunities toembed LLM-powered capabilities into production systems, integrating with existing services and business processes

• Apply strong engineering judgment to ensure solutions arescalable, maintainable, and reliable, balancing speed with long-term quality

• Partner with product, TPMs, and other engineering teams to solve complex supply chain and operational problems

• Driveoperational excellence, including system reliability, observability, and performance optimization

What You’ll Need

• Bachelor’s degree in Computer Science, Engineering, or related field

• 5+ years of professional software development experience with increasing technical ownership

• Strong experience withJava (8+), Spring Boot, and microservices architectures

• Proven experience building and operatingdistributed systems and data pipelines at scale

• Strong understanding ofsystem design, APIs, data modeling, and event-driven architectures

• Demonstrated ability tolead technical initiativesfrom ambiguous problem spaces through production delivery

• Experience mentoring engineers and contributing toraising team-wide engineering standards

• Experience withAWS, CI/CD pipelines, and infrastructure as code

• Strong communication skills and ability to collaborate across teams

• Ability to operate effectively infast-paced, ambiguous environments

AI & Modern Development Experience
