- Collaborate with Data Operations to design human-in-the-loop workflows for efficient review
- Contribute to roadmap planning with Principal-level technical leadership
Infrastructure & Scale
- Build and optimize large-scale inference pipelines for processing millions of documents
- Implement monitoring and alerting for quality degradation and system failures
- Design batching, caching, and fallback mechanisms to balance cost, throughput, and accuracy
- Collaborate with Platform teams on model serving, APIs, and infrastructure scaling
- Maintain clear documentation of annotation strategies, metrics, and known limitations
