Job description

About The Role

We are looking for someone who combines analytical thinking, programming, and strategy development.

Your role will be to turn ideas into working models and algorithms — from concept, through testing, to deployment in real systems.

This is a position for people who enjoy solving complex problems, working with data, and building end‑to‑end solutions.

Katowice | Hybrid

Responsibilities

• Design and develop data‑driven strategies and quantitative models
• Build and implement algorithms in Python
• Develop predictive models (statistical, ML / DL-based)
• Analyze data and identify patterns / signals
• Perform backtesting and validate strategies
• Iteratively improve models based on performance
• Build tools supporting automated decision‑making
• Work with large datasets and real-time data pipelines

Candidate Profile

• Degree in a quantitative field (math, physics, engineering, CS, or similar)
• Strong Python skills (must-have)
• Experience with SQL and working with structured data
• Experience in data analysis, modelling, or algorithm development
• Solid understanding of statistics and time-series analysis
• Familiarity with Machine Learning / Deep Learning concepts:
  • regression / classification
  • tree-based models (XGBoost, LightGBM, CatBoost)
  • basic neural networks (feedforward, LSTM / time-series models)
• Experience with libraries such as pandas, numpy, scikit-learn, PyTorch / TensorFlow
• Strong problem-solving mindset and system thinking
• English (B2+)

Nice to Have

• Experience with neural networks applied to time-series / forecasting
• Experience with optimization techniques and hyperparameter tuning
• Working with real-time / high-frequency data
• Experience deploying models into production (APIs, pipelines)

Who We’re Looking For

• enjoys breaking down complex problems
• can turn ideas into working algorithms
• tests hypotheses instead of relying on intuition
• iterates quickly (build → test → improve)
• is curious about models and why they work (or don’t)

We Offer

• Direct impact on strategies and systems
• Fast iteration cycles and real implementation
• Opportunity to build end‑to‑end solutions
• Growth in quant / algo / data / ML

At ENGIE, every talent has a role to play in accelerating the energy transition.
