Roles & Responsibilities:

• You'll build new product features from start to finish: through conception, research, maintenance, and polish. Think features to improve our collaborative student learning platform, such as new collaborative learning activities for teaching coding and other subjects.
• You'll build improvements to performance, reliability, and product polish — for example, improving the efficiency and performance of our replicated state systems.
