Principal AI-Native Engineer, Ionic Partners

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Principal AI-Native Engineer based in Brazil.

This is a high-impact principal-level engineering role focused on building AI-native systems that operate real business functions in production.
You’ll design, build, deploy, and continuously improve agentic systems rather than prototypes, pilots, or strategy documents.
Working across a diverse portfolio, you’ll partner with domain experts to turn complex functional requirements into reliable autonomous systems.
You’ll shape agent architectures, orchestration, context systems, evaluation frameworks, integrations, observability, and operational safeguards.
The role offers significant technical ownership, with responsibility for system performance, reliability, cost, maintenance, and long-term outcomes.
You’ll work in a deliberately flat, globally distributed environment where influence comes from what you build and the standards you establish.
This is an opportunity to remain deeply technical while working at the forefront of production-grade agentic engineering.
