Staff Product Engineer (Porto Alegre)

About the role

You're the engineering anchor of one initiative at a time. The initiative is a team effort - an iron triangle of you, your PM, and your designer - and you have key participation across the full lifecycle: shaping the problem, deciding the technical approach, leading the AI agents that implement most of the code, shipping to production, and answering for the outcome alongside the rest of the triangle. You're accountable for the outcome - not for the volume of code merged. If an agent can ship it safely, your job is to make sure the agent does it right and the metric moves. If the initiative needs hand-written code in a sensitive area, you write it yourself. What makes this role different: You lead AI agents, not humans. Claude Code, Cursor, Codex, and our internal agent stack are your team. You own the quality, safety, and velocity of what they produce. You own an outcome, not a ticket queue. Problem-framing through production through the metric review 2-4 weeks after launch. You partner horizontally with PM and design. No tech lead above you. No architect approval. No ticket grooming committee. The bar is staff, not senior. You make the call when the call needs to be made. If you're waiting to be told, this isn't the role.
