job responsibilities
A Software Development Engineer (SDE) is expected to design and implement software components while successfully solving difficult problems in open source.

A SDE on the Ray team should have a strong focus on quality and operational excellence while balancing the needs of the business and understanding the tradeoffs required to prioritize delivery.

This focus should extend to both code reviews and design reviews for other SDEs on the team and during deep dives on operational issues. Finally a SDE has to show strong bias for action in delivering on time and work with Sr. SDEs and Software Development Managers (SDMs) to communicate the technical and quality tradeoffs.
