Build and maintain infrastructure: Kubernetes deployments, CI/CD pipelines, and cloud resources (AWS)
Collaborate closely with Operations Research Engineers to integrate optimization algorithms into the product
Work in an AI-augmented development workflow — actively using code agents and AI assistants as a natural part of how you ship software
Contribute to architecture decisions and uphold code quality through reviews, testing, and continuous improvement
Write well-tested, self-documenting code following hexagonal architecture patterns
Share your expertise and mentor colleagues, promoting a culture of knowledge sharing and learning
