AI Lead Solutions Architect

About Workana

Workana is the largest remote work platform for talent in Latin America. Our division focuses on matching exceptional professionals with leading and innovative companies around the globe.

About the Client

Our client is a premier global financial institution committed to driving innovation and technical excellence across its core banking and digital services. They are looking for an experienced AI Lead Solutions Architect to drive strategic artificial intelligence and machine learning initiatives, architect scalable solutions, and mentor engineering teams.

This is a hybrid opportunity for professionals based in Toronto, Canada, working closely with an international team in an English-speaking environment.

Role Overview

As an AI Lead / Solutions Architect, you will lead R&D efforts and technical execution for complex AI/ML applications in financial services, including document intelligence, automated decisioning systems, and multi-agent workflows. You will design end-to-end architectures from model design to scalable production deployment while driving technical innovation using modern AI techniques such as retrieval-augmented generation (RAG) and transformer models.

In addition to technical ownership and architecture design, you will mentor junior engineers, guide team members in AI/ML concepts, and lead cross-functional project execution across ML engineers, backend developers, and business stakeholders to turn technical capabilities into tangible business outcomes.

Selection Process

The process usually consists of 3 stages and takes on average 4 weeks to be completed, depending on eventual additional technical rounds or take-home tests.

• Initial interview with Workana's recruiting team;
• Cultural fit interview with the client;
• Final interview with C-level.

As Workana has multiple clients, if you pass the first round with Workana's recruiting team, you may also be considered for other relevant opportunities if the initial opportunity does not move forward.
