You will bridge the gap between raw data and production-ready intelligence.
What you’ll do
Operational & Tactical Management
-
Model Development: Train and fine-tune models independently using state-of-the-art frameworks.
- Experimentation: Design rigorous experiment plans, including benchmarking and ablation studies, to drive model evolution and improvement.
- Dataset Strategy: Design dataset preparation, filtering, and versioning strategies and tools to ensure high-quality training data.
- Evaluation & Optimization: Define evaluation protocols, apply model optimization techniques, and export models for specific production targets.
- Pipeline Integrity: Maintain reproducible experiment pipelines and produce detailed technical evaluation reports.
Strategic Contribution
-
Workflow Improvement: Propose and implement enhancements to internal training and evaluation workflows.
- Best Practices: Contribute to the definition of model engineering standards and review experiment pipelines developed by junior team members.
- Collaboration: Coordinate with Production Engineers on model I/O and constraints, and support external technical demos or presentations.
As we imagine you...
Soft skills
-
Experimental Rigor: A meticulous approach to testing and documenting results.
- Proactive Mindset: Ability to identify bottlenecks and propose technical solutions.
- Communication: Skilled at translating complex model behaviors into clear reports and collaborating across teams.
- Growth Orientation: A continuous learning mindset and receptiveness to peer feedback.
Experience
-
3-6 years of experience in AI Model Engineering
- Degree in Computer Science, Data Science, Mathematics, or a related field.
- Deep understanding of the AI model lifecycle, MLOps fundamentals, and model optimization.
- Proficiency in both English and Spanish is required.
Technical knowledge:
-
AI & Model Engineering
- Frameworks: Advanced Python, PyTorch, and TensorFlow (specifically custom loops).
- Libraries: HuggingFace (Transformers/Datasets), OpenCV, Albumentations.
- MLOps & Tools: MLflow (experiment tracking), DVC (versioning), and Optuna/Ray Tune (hyperparameter tuning).
- Optimization: Model quantization, pruning, and ONNX validation.
- Data Analysis: Proficiency in pandas profiling, data drift checks, and bias analysis (distribution skew, label bias).
- Environment: Docker, Bash scripting, and SQL (advanced queries).
- CI/CD: GitFlow, GitLab CI, or GitHub Actions.
- Cloud: Basic experience with AWS S3 or similar cloud storage.
- Testing: Advanced usage of pytest and config-driven pipelines.
- Multimedia: Basic knowledge of GStreamer development is a plus.
Is this you?? Let’s meet!
