ML engineer vs data scientist, what's the difference?
Data scientists prototype and analyze. ML engineers productionize and operate. If you need models that serve real traffic reliably, hire an ML engineer. If you need research and experimentation, hire a data scientist. Many senior people blur the line, we screen for the production side.
ML engineer vs LLM engineer, which do I need?
LLM engineers build on top of existing models (OpenAI, Anthropic, open-weights). ML engineers train and deploy custom models. If your product needs a bespoke model (classification, recommendation, computer vision), hire an ML engineer. If your product is primarily a GenAI feature, hire an LLM engineer.
Do your ML engineers do MLOps?
Yes. Senior ML engineers are expected to own MLOps end to end: feature stores, model registries, CI/CD, monitoring, drift detection, retraining. If a candidate cannot explain their MLOps approach, they are not senior.
What frameworks do they know?
PyTorch, TensorFlow, scikit-learn, XGBoost, LightGBM for modeling. MLflow, Kubeflow, Airflow, dbt for ops. Framework fluency matters less than architecture fluency, we screen for both.
Can they work with real-world messy data?
Yes, that is where senior ML engineers earn their keep. Feature engineering, data quality, and label noise are the real problems. Model choice is usually the easy part.
Should I hire an ML engineer or use your AI Development service?
Hire when you want a dedicated engineer on your team long-term; use our AI Development service when you want us to build it with you. We will help you decide on the call.
What does a senior ML engineer in LatAm cost?
Typically 50% below US rates for equivalent seniority. See the Compensation Report or book a call for specifics.
Can I hire an ML engineer part-time or on contract?
Yes. Direct-hire, contract-to-hire, or embedded contractor, we structure around how you want to work. Start with a call.
