Software Engineer, Frontend

Monaco is building an AI-native revenue platform that replaces the fragmented GTM stack - CRM, sequencing, call recording, enrichment, pipeline management with one unified system, consolidating 6–10 disconnected tools into a single platform built for the AI era. We launched publicly in Feb 2026, are already 65 people, and have strong early product-market fit generating millions in ARR within months of launch. You'll have the chance to both scale our core systems and build new features from 0 to 1. We've raised $85M in our Series B from Founders Fund, Benchmark, and Human Capital, and our founders previously led Brex, Apollo, and Clari. Come join us if you want to be part of a high autonomy, high pace team reinventing one of the biggest categories in enterprise software.

Excited about new UI patterns (LLM UX, streaming, partial state, etc.). Solid fundamentals in modern frontend tools (React, TypeScript, component systems). Nice to Have Built real-time or chat-style interfaces (streaming responses, tool outputs). Worked on design systems or component libraries. Experience making unreliable or evolving data feel stable and intuitive. Location San Francisco. We're an in-person team - 5 days in the office.
