Staff Software Engineer (Backend)

WHAT ARTISAN IS

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 $8M+ ARR. Right now we're building Ava 2.0, a step change in what an AI employee can do. The engineering problems are hard and the surface area is enormous.

THE ROLE

- You’ll build the backend that makes AI employees possible. This is a foundational engineering role.

- We process millions of signals — lead data, email engagement, deliverability metrics, behavioral patterns — to make autonomous decisions. The backend is core to everything we do: it powers the AI, runs the platform, and determines how well Ava performs for every customer. You’ll own major parts of it.

WHAT THAT LOOKS LIKE CONCRETELY:

- High-throughput AI orchestration.

- Design and build the services and pipelines that allow Ava to process massive volumes of signals and make fast, reliable decisions.

- Platform infrastructure.

- Artisan replaces an entire sales stack: email infrastructure, CRM, lead database, campaign engine, inbox management, and AI coordination — all in one product. You’ll own real pieces of this platform.

- High ownership, end to end.

- Design it, build it, deploy it, monitor it. We don’t separate architecture from implementation. You own outcomes, not tickets.

Moving and iterating very fast.

- You’ll ship constantly. We run a flat engineering org with minimal process and no red tape.

- Our stack: TypeScript/Node, PostgreSQL, Redis, Kubernetes, Mastra, Temporal, Langfuse, ECS, EC2, deployed on AWS. We release cont...
