Ubiminds is a GPTW-certified, people-first company that partners with American software product companies to scale their development teams. We connect Brazil’s top 5% talent with innovative U.S. companies through a unique combination of staff augmentation and employer-of-record services.

We are supporting a cutting-edge company building an AI-first coding platform (think Replit) and looking for a Software Architect with strong AI/Agentic experience to lead this initiative.

 

We’re looking for a Software Architect who can design the future of software development—where autonomous AI agents and human developers collaborate seamlessly.

This role is ideal for someone who thrives at the intersection of AI, system design, and developer platforms, and is excited to build systems where agents can plan, write, test, and deploy code autonomously.

You will play a key role in defining how agentic workflows, LLM reasoning loops, and developer tooling come together in a scalable, production-grade platform.
