Collaborate closely with other engineers through technical discussions, pair programming, and knowledge sharing.
Help define and promote best practices around GraphQL and AWS serverless development.

Contribute to new capabilities around search and discovery, including vector-based approaches.
Join a project where there is room to challenge existing solutions, improve patterns, and introduce better ways of working.
