Senior Machine Learning Engineer

As our portfolio of work continues to grow we are looking for an experienced Machine Learning Engineer to join our data science and machine learning team.  The individual will work closely with the data and machine learning specialists software engineers and commercial teams to deliver machine learning models and applications.   We work across the trading business operations and other support functions; so the individual will need to be comfortable working with a variety of stakeholders and technologies.

The Machine Learning Engineer at Vitol has visibility and impact across the full project workflow: from working with business stakeholders to help define the project to data collation and processing exploratory analysis model selection and tuning and implementation of production models. 

The successful candidate will join a team of experienced collaborative practitioners who are (pragmatically) solving some of the most challenging and impactful problems the energy industry is facing; as well as pushing the boundaries around the art of the possible.

Core Responsibilities include:

• Design develop and deploy end-to-end machine learning and data science solutions across our wider business activities (including trading operations and support functions) - from raw data ingestion through to production-grade models and monitoring
• Drive adoption and development of the firms internal GenAI chat platform as one of the technical leads extending its capabilities through new integrations data connectors and domain-specific prompt engineering; work closely with trading desks and operational teams to identify high-value use cases embed the tool into day-to-day workflows and ensure outputs are robust and trusted by end users.
• Apply a broad range of modelling techniques - including time-series forecasting NLP classification and generative AI - to commodity pricing supply/demand signals trade flow analysis and operational optimization problems
• Own the full data science lifecycle on assigned projects: data sourcing and cleaning exploratory analysis feature engineering model selection and validation deployment and ongoing performance monitoring
• Build and maintain robust well-tested production-quality code; contribute to shared infrastructure including ML pipelines data orchestration and model serving layers
• Integrate ML and GenAI outputs into existing trading systems dashboards and workflows; work with software engineers to ensure reliable scalable adoption across the business
• Communicate analytical findings and model outputs clearly to non-technical stakeholders; present results assumptions and limitations in a manner that supports confident commercial decision-making
• Actively participate in code reviews experiment design and tooling decisions; mentor colleagues and help raise the overall standard of analytical and engineering practice across the team

Qualifications :

• Masters degree or equivalent in Computer Science Statistics Mathematics Data Science or a related quantitative field
• Fluency in Python for both data science and engineering purposes: clean modular well-documented code with strong understanding of software engineering best practices including version control testing and code review
• 5 years of industry experience developing and deploying machine learning or statistical models with a proven track record of delivering end-to-end solutions in production environments
• Demonstrable experience applying a broad range of ML methodologies (supervised and unsupervised learning time-series modelling NLP/LLMs optimization) to real-world business problems
• Strong proficiency with ML frameworks (e.g. PyTorch scikit-learn Transformers) and experience building or consuming LLM-based pipelines and GenAI applications
• Experience with cloud platforms (AWS preferred) and modern MLOps practices: containerization (Docker/Kubernetes) CI/CD data pipeline orchestration (e.g. Airflow Dagster) and model serving
• Strong analytical and problem-solving ability: capable of defining and scoping open-ended problems proposing sound methodological approaches and defending modelling choices with rigorous reasoning
• Excellent written and verbal communication skills with the confidence to present model outputs caveats and commercial implications clearly to non-technical audiences including traders and senior management
• Genuine intellectual curiosity about commodities markets global energy flows and the commercial dynamics of trading; willingness to develop domain knowledge as part of the role

Desirable Experience

• Experience in the energy or commodities trading industry with knowledge of financial markets and trading concepts
• Experience surfacing ML outputs through interactive tools (e.g. Dash Streamlit or similar) and presenting use cases to non-technical audiences including traders and senior management
• Time-series modelling in a trading or financial context including both ML-based and econometric approaches (e.g. ARIMA cointegration regime-switching models)
• Data orchestrators (Airflow Dagster) and cloud-based ETL/ELT pipelines
