Principal Software Engineer - Notetaker

Principal Software Engineer - Notetaker Cambridge, MA, USA POS-31595 About the Team The Notetaker team is building the intelligence layer for live customer conversations. Their mission is to make it effortless for front‑office teams to win every meeting and call—across video and voice. The team owns the full lifecycle of a live conversation: capturing and transcribing conversations with high accuracy, streamlining meeting setup and preparation through deep calendar and workflow integrations, and turning raw dialogue into clear, actionable outcomes. By combining best‑in‑class transcription with adaptive summaries, follow‑ups, and conversation intelligence, Notetaker lets teams focus on the human moment while the system handles everything around it. About the Role We’re seeking a Principal Software Engineer to play a pivotal role in shaping the technical future of Notetaker. This role sits at the intersection of real‑time systems, distributed infrastructure, and applied AI. As a Principal Engineer, you will define how live audio/video, transcription, and GenAI‑powered insights come together into a reliable, low‑latency, production system. You’ll help the team move fast without breaking trust—shipping features that feel magical to users while remaining robust under real‑world conditions. Key Expectations Architect real‑time conversation systems: Define patterns for ingesting, processing, and storing live audio and video data with high accuracy and low latency. 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, summarisation, 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. Org‑level multiplier: Mentor senior engineers, influence architectural standards, and help the org build better real‑time and AI‑powered systems. What You Bring Deep experience building distributed systems with real‑time or near‑real‑time constraints. Familiarity with audio/video pipelines, streaming systems, or event‑driven architectures. Practical experience applying GenAI to user‑facing products, especially summarisation, classification, or insight generation. Strong judgment around trade‑offs between speed, quality, cost, and correctness. A bias for action: you prefer working systems over perfect abstractions, and you stay hands‑on through delivery.
