- Collaborate with product owners and domain experts to implement complex supply chain planning algorithms
- Participate in architecture discussions and technical design reviews
- Write comprehensive unit and integration tests using JUnit
- Contribute to CI/CD automation and cloud-native deployment pipelines
- Support, monitor, and troubleshoot production systems, owning issues through to resolution
- Work effectively with teammates across multiple time zones and geographic regions
- Leverage AI-assisted engineering tools, agents, and workflows to improve development productivity while maintaining high standards of code quality

Preferred Qualifications
Experience with one or more of the following is highly desirable:
- AWS Batch
- AWS CloudFormation
- Bitbucket Pipelines or comparable CI/CD platforms
- Database procedural languages such as PL/pgSQL, IBM Informix 4GL, or similar technologies
