Provectus

Mid-Level ML Engineer

Colombia Remote March 31, 2026 Full Time Lever

Role Purpose

As a Mid-Level ML Engineer at Provectus, you will work with increasing independence to design, implement, and deploy production-grade ML solutions for our clients. You sit at the bridge between learning and leading: you no longer require task-by-task guidance, yet you continue to grow toward senior technical ownership. A defining characteristic of this role is proficiency in AI-assisted development. You will leverage AI coding tools, contribute to agentic engineering initiatives, and actively shape Provectus's internal AI toolkit. You will also mentor junior engineers and contribute meaningfully to technical design decisions.
