Shakers for companies
Work with a contract Machine Learning Engineer
A certified Machine Learning Engineer who takes your model beyond the notebook: they prepare the data pipeline, train with PyTorch or scikit-learn, evaluate, and leave the system serving with MLflow, containers and watched drift.
The prototype that works locally and expires in production is the pain this solves. One specific person, chosen for their speciality, with a budget set by scope.
- Certified talent in AI and agent skills
- Meet up to 3 AI Builders in 72 h
- Flexible collaboration models

The talent mix your company needs
At Shakers you will find AI Engineers and specialists across Tech, Product and Data
What this profile brings to your project
A Machine Learning Engineer designs, trains and deploys machine learning models: prepares the data, trains and evaluates with Python, PyTorch or scikit-learn, and takes the model to production with pipelines, containers and monitoring. The deliverable is a system that learns, not a report.
Their boundary: the data scientist explores and decides, the AI Engineer builds on foundation models and LLMs, and MLOps industrialises what another trained. The ML Engineer takes the model from data to system.
One provider. One contract. Full traceability

Why work with Shakers
The advantages of adding this profile with Shakers
From notebook to production
The prototype that worked locally, now serving: pipeline with MLflow, containers and watched drift. The jump nobody documents.
Own models on your data
PyTorch, TensorFlow or scikit-learn by the case, trained on your history and judged by the business metric agreed up front.
The data triad clarified
ML, data scientist or AI Engineer? The boundary follows the pain: models and production, analysis and decision, or LLMs and RAG.
The foundation layer included
Fine-tuning, embeddings and RAG when the case asks for them: the craft today also builds on foundation models.
Continuity if the specialist moves on
If the specialist changes, the pipeline stays: experiments versioned in MLflow and another certified talent picks up the model.
Capacity without growing headcount
A Machine Learning Engineer on demand, no hiring process: they arrive on your data and your cloud and scale when the model asks.

What gets delivered in the first weeks
The business metric defined, the first model trained and evaluated on your data, and the production decision documented: what gets deployed, how it gets served and what gets watched when the data shifts.
A market that already titles the craft
329 active tech ads in Spain mention machine learning engineer, with literal titles crossing sectors, from '(MLOps and Forecasting)' at METRICA to '(GenAI/LLM/RAG)' at Bluetab and 'Automated Driving' at Mitsui (Shakers market analysis, n=31,957, September 2026). The market wants the whole craft: data, model and production.
Foundation models without losing the craft
Much of the work that started from zero today builds on foundation models: fine-tuning, embeddings and RAG. That does not replace the ML Engineer; it moves the starting point, and whoever masters both halves covers your project end to end.

Data Scientist
The data scientist explores and decides; the ML Engineer builds and ships. Ads fuse them into dual titles; here the boundary arrives written in.
AI Engineer
The other frontier: LLMs, agents and RAG on foundation models. If the pain is the AI product rather than the own model, their row builds that layer.
Data Engineer
The channel your data arrives through: Spark, Airflow and pipelines. When the history is not ready, their row builds the supply the model drinks from.
Python Developer
The language of the craft: pandas, APIs and automation. When the model already serves and the application around it is missing, their row builds the product.
