Engineering Manager
Senior technical leader for AI voice and SMS platform and open‑source AI infrastructure, driving architecture, code reviews, and production engineering while managing a remote team and overseeing cloud‑native deployments.
Lead Engineer & Technical Lead — AI Platform
Custom AI Solutions | Remote (Brazil) | Independent Contract Engagement
About the Role
Custom AI Solutions is seeking an experienced independent Lead Engineer & Technical Lead to provide senior technical leadership across VoxaCor™ and BridgeNode™. Engaged through your own registered Brazilian entity, you will operate as an independent technical lead — setting architectural direction, performing code review, and providing hands-on production engineering — while controlling your own methods, tools, and working schedule.
VoxaCor™ is our AI voice and SMS platform built for high-volume, real-time communication. BridgeNode™ is the open-source AI conversation framework that powers it — every product CAIS builds runs on it. You will engage across both as the senior technical voice on the platform.
AI-first development is core to how we build. This engagement suits an experienced technical lead who has shipped production AI systems and guided other engineers doing the same. If that is not your background, this engagement is not the right fit.
Engagement Structure
This is a business-to-business engagement, contracted through your registered Brazilian entity. As an independent contractor, you control how and when you perform the services, supply your own equipment, and invoice CAIS for work delivered. The engagement is structured as a long-term, renewable relationship based on agreed scope and deliverables — not employment. A registered legal entity in Brazil is required. This is a firm requirement and is not negotiable.
