Niuro connects top LATAM technology talent with international companies. Our mission is to become a strong bridge between highly skilled engineers in Latin America and companies building complex, production-grade technology products abroad. For this role, the selected professional will work with a US-based company in the online tax filing industry. The client operates in a regulated environment where reliability, data accuracy, security, and operational continuity are critical.

This position is ideal for a senior technical leader who can understand the full picture of a complex production environment, identify architectural risks, and help transform legacy systems into a more scalable, AI-enabled technology foundation. This is a Senior Principal Architect role for a technical leader who drives transformation, not just plans it. You will own two parallel initiatives: re-platforming a complex legacy stack and architecting the foundation for a new AI-driven product suite.

    • MLOps experience for production AI/LLM systems.
    • Cloud platform experience, preferably AWS; GCP or Azure also valued.
    • Event-driven architecture and asynchronous workflow design.
    • Microservices architecture in complex or legacy modernization environments.
    • Experience applying AI/LLMs to analytics, data workflows, or operational decision-making.
    • Background in regulated industries such as tax, fintech, accounting, insurance, legaltech, or healthcare.
