• design and optimize caching strategies (including, perhaps, the inclusion of new data storage
• mediums/platforms) for cohort output, differentiated as needed to serve multiple distinct read patterns from consumers
• recommend and implement additional pre-calculation and caching strategies as needed to ensure that SLAs are met
• promote API versioning best practices and open API standards in development
• cooperate with product managers to understand the variety of internal and external cohort specification needs across a diverse set of use cases

• demonstrably deep experience with Python

• experience designing APIs for use in web application development (synchronous vs asynchronous response patterns, caching strategies, etc.
• experience with separate caching/cache invalidation strategies, particularly tiered strategies for highly variable unit volumes of data
• experience with multiple relevant data storage platforms, and the ability to understand the benefits of drawbacks of each for specific types of read patterns (‘data lakes’ like S3/Hive-based systems, RDBMS, MPP platforms, KV/doc stores, etc)
• understand and design for non-functional concerns such as performance, cost optimization, maintainability and developer experience
• strong communication with engineers, product managers, data scientists and commercial teams
