Senior Engineer, Aspiring AI Builder

Remote - US

| Contract

Our client is a startup growing fast enough that machine learning is becoming core to the product's direction. They're ready to move ML out of prototypes and into production, but they don't yet have any in-house ML expertise.

This role is built for a strong, self-directed software engineer who's been tinkering with AI/ML and wants to make it the center of their work. You won't be inheriting an established ML practice or a senior specialist to lean on. You'll be the one figuring things out, making the early calls, and building the foundation others will eventually work on top of. Your senior engineering background is what makes that possible: you already know how to ship reliable production systems, and you'll apply that discipline to ML while teaching yourself the modelling side as you go. If you're the kind of engineer who learns by building, reads the docs and the papers, and gets a kick out of being handed an open problem, this is a rare chance to own AI from the ground up.

This is a long-term contract opportunity without an end date. The engagement is fully remote. Candidates must be located in Latin America. You'll need strong English communication skills (B2+ or higher) for this role.

Mandatory Requirements

• 5+ years of professional software engineering experience, with a track record of shipping and maintaining production systems.
• Strong Python proficiency, it's the primary language for this work, and you're comfortable writing clean, production-grade code in it.
• A demonstrated ability to teach yourself hard things: you've picked up new domains, tools, or stacks on your own and gotten them to production. This is the single most important quality for this role.
• Hands-on tinkering with AI/ML: side projects, experiments, coursework, or professional exposure. You don't need years of it, but you've gone past reading about it and actually built things.
• Solid experience deploying and operating ap...
