Role Overview :

We are seeking a Machine Learning Engineer to lead the end-to-end development of production-grade analytical applications. This is a high-impact role requiring a blend of deep statistical modeling and machine learning. You will be responsible transforming raw consolidated data into high-accuracy forecasts through advanced feature engineering, rigorous model selection, and statistical validation.

This role is for an engineer who thrives in the research-to-code transition, ensuring that every model is mathematically sound, resistant to overfitting, and optimized for high-dimensional manufacturing data.

Responsibilities :

- Feature Engineering & Discovery : Design and build complex feature sets for diverse problem types, including behavioural features for churn, sensor-based lags for maintenance, and seasonal encodings for demand forecasting.
- Model Selection & Optimization : Conduct systematic experimentation across diverse algorithms (e.g., XGBoost, LightGBM, Prophet, or Deep Learning) to identify the best-performing models.
- Model Training & Testing : Develop, train, tune, and test a variety of ML architectures including time-series, classification and regression.
- Statistical Validation & Evaluation : Define and track complex evaluation metrics tailored to manufacturing, such as MAPE, RMSE, etc., while performing deep-dive bias-variance analysis.
- EDA & Research : Perform exploratory data analysis on consolidated "Gold" layer data to uncover hidden drivers of business outcomes and identify correlations between external signals.
- Refinement & Performance Tuning :



Address critical modeling challenges including bias-variance tradeoffs, class imbalance, and overfitting to ensure models generalize to real-world production data.

Skills & Requirements :

- 3+ Years of Experience : Proven track record of developing and delivering production-grade ML models across multiple domains (Sales, Finance, Manufacturing, or Supply Chain).
- Mastery of the Python Ecosystem : Expert-level skills in Pandas, NumPy, Scikit-learn, and SciPy.
- Advanced Algorithmic Knowledge : Deep expertise in supervised and unsupervised learning, specifically ensemble methods (Boosting/Bagging) and time-series frameworks.
- Statistical Foundations : Solid grasp of hypothesis testing, probability distributions, and the mathematical principles behind model evaluation and optimization.
- SQL Proficiency : Expert ability to manipulate data within consolidated database layers to create the "Silver" feature sets required for training.
- Education : Bachelors or Masters degree in a quantitative field (e.g., Data Science, Statistics, Mathematics, or Computer Science).
- Cloud Awareness : Experience with Azure Machine Learning or similar cloud modelling environments.
- Engineering Familiarity :



Basic understanding of Docker, MLflow, or FastAPI for handing models off to deployment teams.

Personal Attributes :

- Strong problem-solving skills with a passion for data architecture.
- Excellent communication skills with the ability to explain complex data concepts to non-technical stakeholders.
- Highly collaborative, capable of working with cross-functional teams.
- Ability to thrive in a fast-paced, agile environment while managing multiple priorities effectively.

Competencies :

- Tech Savvy - Anticipating and adopting innovations in business-building digital and technology applications.
- Self-Development - Actively seeking new ways to grow and be challenged using both formal and informal development channels.
- Action Oriented - Taking on new opportunities and tough challenges with a sense of urgency, high energy, and enthusiasm.
- Customer Focus - Building strong customer relationships and delivering customer-centric solutions.
- Optimize Work Processes - Knowing the most effective and efficient processes to get things done, with a focus on continuous improvement.

Why Join Us?

- Be part of a collaborative and agile team driving cutting-edge AI and data engineering solutions.
- Work on impactful projects that make a difference across industries.
- Opportunities for professional growth and continuous learning.
- Competitive salary and benefits package.
