Staff Software Engineer (Backend) at Artisan

We're building AI employees. Not chatbots. Not copilots. Autonomous digital workers that do real jobs. Our first, Ava, is an AI BDR used by hundreds of companies. She researches leads, writes and sends emails in a customer's voice, runs multi-step outbound sequences, manages her own deliverability infrastructure, self-optimizes over time, and handles objections and meeting booking. She's not a tool someone uses. She's a teammate. We're a YC W24 company, have raised $35M+ from investors including Y Combinator, and are at $9M+ ARR. We just launched Ava 2.0, a step change in what an AI employee can do. The engineering problems are hard and the surface area is enormous. You'll build the backend that makes AI employees possible. Concretely: High-throughput AI orchestration. Ava processes millions of signals - lead data, email engagement, deliverability metrics, behavioral patterns - to make autonomous decisions. You'll build the services and pipelines that make this fast, reliable, and correct. Platform infrastructure. Artisan replaces an entire sales stack. That means email infrastructure, CRM, lead database, campaign engine, inbox management, and AI coordination - all in one product.
