Senior Machine Learning Engineer (Burzaco)

We are a Silicon Valley based product company building a next‑generation AI‑native B2B platform for hospitality. We’re looking for a Senior Machine Learning Engineer who is excited about the craft of machine learning—especially the mathematical and statistical foundations behind models—and who can turn that depth into solutions that scale in real-world use. If you’re someone who enjoys choosing the right model for the problem, validating it rigorously, and improving it through iteration, you’ll feel at home here.

This is an opportunity for an engineer who wants to grow into a future architect, help define large-scale backend systems, and become a true technical champion within the team. If you are passionate about modern backend engineering, clean architecture, and scalable distributed systems, you’ll love working with us.

What you’ll do
- Design, train, and improve statistical and machine learning models for real product use cases.
- Apply strong fundamentals in probability, statistics, and modeling to make sound decisions on approach and evaluation.
- Build scalable ML solutions that can be used reliably in production environments.
- Develop capabilities to support agent‑like experiences within our platform (e.g., intelligent workflows, tool‑using behaviors, retrieval patterns, guardrails).
- Define and monitor meaningful model metrics, run error analysis, and iterate based on results.

What we’re looking for We’re intentionally not treating this as a checklist. If you’re strong in the fundamentals and have built real ML systems, we’d love to hear from you.

You’ll be successful in this role if you have:
- Strong knowledge across a broad range of machine learning algorithms (supervised/unsupervised methods, ensembles, linear models, tree‑based methods, deep learning basics) and the judgment to choose appropriately.
- Solid grounding in statistics and mathematical reasoning (e.g., bias/variance tradeoffs, uncertainty, evaluation design).
- Experience building ML Postúlate en Kit Empleo: kitempleo.com.ar/empleo/pm7hs
