Job Level
About the role
- Design, develop, and optimize ML models—including XGBoost, Random Forests, SVMs, CNNs, and Transformers.
- Lead hyperparameter tuning, feature selection, and algorithm evaluation.
- Integrate models to production system, work with SW team on optimizing runtime speed and performance
- Develop reproducible training pipelines with model, data, and experiment versioning.
- Extract temporal, spectral, and domain‑specific features from raw sensor signals.
- Use data analytics tools such as UMAP and T-SNE to understand data distribution and feature characteristics.
- Model sensor characteristics such as noise, bias, drift, and environmental effects.
- Perform ablation studies and feature importance analyses (SHAP, PDP, etc.).
- Design multi‑class object detection and classification pipelines for noisy, imbalanced datasets.
- Define evaluation metrics including confusion matrices, calibration, and class‑wise scoring.
- Deploy production‑ready ML code impacting real customers.
- Ensure reliability through CI/CD, drift detection, and data validation.
- Optimize models for edge and compute‑constrained environments.
- Work with hardware, software, product and cross-functional teams.
- Communicate technical decisions and trade‑offs to senior stakeholders.
Requirements
- Master’s or PhD in Computer Science, Machine Learning, Engineering, Applied Math, Physics, or related field.
- 3- 5+ years building and deploying ML models for real-world applications
- Strong expertise in classical ML techniques (e.g., XGBoost, Random Forests, SVM, k‑NN) and modern ML techniques (e.g., deep neural network, transformers).
- Proficiency in Python, ML libraries (scikit‑learn, NumPy, pandas) and C++
- Experience with multi‑class classification on real‑world, noisy datasets.
- Strong statistical and model evaluation skills.
