development primarily on UNIX-based or OSX-Darwin platforms
working proficiency (≥C1) in speaking, reading, and typing English (≥45 words per minute)
willingness and interest in working with people from other cultures
emotional resilience and social intelligence
and you have to care about the work that you do
and you have to be optimistic at least sometimes, although pessimism tends to be useful
Below are additional skills that are a bonus, but are not required:
understanding of analytical data modeling concepts, including how to transform raw data into analytics-ready datasets and define clear data semantics for downstream consumers
experience with Python, Django, DBT, Dagster, Luigi or Clickhouse

What can you expect:
unusual, socially conscious projects
significant ownership
a mix of product, internal platform, and client integration work
ability and encouragement to explore technologies other than your main expertise
optional travel to learn more about problems we're trying to solve
