Hands-on, high-impact delivery: Write production code, lead major initiatives, and own critical systems end-to-end.
GenAI in the loop: Shape how transcription, summarization, and conversation intelligence models integrate into live and post-call workflows.
Reliability and trust at scale: Drive decisions around observability, correctness, privacy, and failure modes in non-deterministic systems.
Product and UX sensitivity: Partner with Product and Design to ensure technical decisions support clarity, usefulness, and user trust.
Cross-functional influence: Work closely with Calendar, Calling, CRM, and AI teams to align on shared primitives and patterns.
