A pioneering tech firm in São José dos Pinhais is seeking a Backend Engineer to design, build, and scale systems that power AI employees. The ideal candidate has over 6 years of experience in backend engineering within high-growth environments and is proficient in AWS and GitHub Actions. You will own significant parts of the system and have strong communication skills. This role offers equity compensation and a collaborative culture.
At Artisan, we’re building real AI employees - not copilots, not assistants, but autonomous teammates.
Our first, Ava, is an AI BDR. She finds and researches leads, writes emails in customers’ tone of voice, runs outbound sequences, self‑optimizes, and manages email deliverability infrastructure. She learns, adapts, and improves over time - just like a human would.
Human team members use Artisan as their primary working platform, replacing a sprawling stack of sales tools, and have Artisans working alongside them.
We went through Y Combinator (W24) and have raised $35M+ from top investors. We’re at $7M+ ARR, with hundreds of customers including Remote, Quora, and SumUp. We’re currently working on Ava 2.0, pushing the boundaries of what an AI employee can do. And we’re hiring.
You’ll design, build, and scale the backend that powers AI employees while following our principles :
6+ years of backend engineering experience in high‑growth environments, preferably early‑stage or Series B.
Strong experience building scalable, data‑intensive services with modern APIs and robust infrastructure.
Proficiency with AWS and GitHub Actions.
Deep understanding of distributed systems, APIs, reliability, performance, and database systems (SQL + NoSQL).
Experience with modern stacks - TypeScript / Node preferred, but equivalent backend stacks are welcome.
Demonstrated track record of ownership – leading parts of systems independently and shipping with impact.
Excellent communication, clarity in articulating architecture to technical and non‑technical stakeholders.
