-
Collaboration-first approach – you support your teammates, share knowledge, and help build a strong team culture
-
A sense of responsibility – you care about the outcomes for your team, your project, and the client

-
Contributing to both current and future product architecture and design decisions
-
Collaborating closely with developers, QA engineers, and product stakeholders to deliver value
