Principal Software Engineer, Data Infrastructure

We are looking for someone who builds the engine rather than someone who just maintains or configures existing setups. You have driven major structural overhauls and 1-to-N platform evolutions at hyper-scale (100M+ active users). Strong Engineering Foundations: Robust proficiency in Java, Go, or Scala , with a track record of writing clean, highly performant backend code. Cloud Fluency: Proven expertise managing, scaling, and troubleshooting complex stateful and stateless multi-cluster data infrastructure running on top of Kubernetes within AWS or GCP. Cross-Organizational Technical Leadership: A proven track record of influencing technical direction across a large engineering organization, leading consensus on complex architectural initiatives, and championing successful multi-quarter projects. Extreme Ownership: A history of radical accountability. You do not wait for clean specifications in high-ambiguity environments; you actively define the technical requirements, unblock dependencies, rally engineers across pods, and steer complex projects from initial whiteboard sketch all the way to production stability. Nice to Have: Contributions to open-source projects in the data infrastructure ecosystem. Experience operating infrastructure at consumer-internet scale (100M+ users).
