About 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 $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.

Role overview

You'll be the third Applied AI engineer on the Artisan team! We're pushing the boundaries of what's possible with AI employees, and you'll play a key role in our product direction.

• Evaluating LLMs, choosing the right models for the right tasks, balancing cost, latency, reliability, and accuracy

• Architecting prompt frameworks and agent behaviors for Ava’s core workflows: email generation, chat interaction, meeting scheduling, prospect research, and more

• Optimizing multi-step agent chains using retrieval-augmented generation (RAG), web search integrations, and tool use (e.g. CRMs, calendars, APIs)

• Driving infrastructure choices for routing, orchestration, eval loops, and persistent memory across agents

• Building safety, trust, and controls into agents, partnering with product to design user guardrails, fail-safes, and success metrics

• Exploring and deploying emerging modalities from voice AI and talking head technology to multi-modal reasoning - and figuring out how they make Ava more human-like

• Designing agent workflows that make strategic decisions, self-optimize and adapt in real time, and deliver measurable outcomes autonomously

Team: AI

Reports to: CPTO, Sam Stallings

Who you are

• 2+ years shipping real AI products in production - either at an app-layer AI startup or on a foundation model team

• Deep hands-on experience with agents, function calling, RAG pipelines, or self-healing workflows (LangChain, ReAct, Dust, OpenAI Tools, etc)

• Strong background in prompt design, chaining, and retrieval systems (experience with OpenAI’s RAG + web search tools or equivalents is a major plus)

• Experience owning latency, reliability, and cost of LLM-powered systems in production

• Ability to think like a researcher but ship like an engineer, exploring novel techniques and getting them into users’ hands quickly

• Excellent communication skills
