About the role
What You Will Do
- Design and build the core services, deciding how the system is decomposed, where state lives, and how components communicate
- Work wherever the problem leads, from data model to product surface
- Make deliberate tradeoffs across accuracy, consistency, availability, and latency
- Define the internal APIs and abstractions that determine system trajectory 6+ months out
Who You Are
- You have built non-trivial systems and can speak honestly about what aged well and what did not
- You understand distributed systems tradeoffs well enough to make the right call for a given problem
- You are comfortable on both sides of the stack and choose where to work based on the problem
- You have strong opinions about software design and can defend them without being precious about them
