• Translate complex quantitative concepts into clear, actionable insights for both technical and non-technical stakeholders.
• Partner with Risk Management, Middle Office, Trading, and Finance teams to ensure models are appropriately implemented and understood.
• Support external audits and assurance reviews by providing expert guidance on valuation and quantitative methodologies.
• Contribute to key projects that shape the future of risk analytics within one of Europe's leading energy companies.

• Strong understanding of derivative valuation methodologies and market and credit risk measurement techniques.
• Deep knowledge of probability theory, stochastic processes, time series analysis, and mathematical modelling.
• Hands-on experience developing and maintaining market and credit risk models, including Monte Carlo simulation techniques.
• Programming experience, ideally within version-controlled environments such as GitHub.
• Strong analytical mindset with a natural ability to challenge assumptions, identify model limitations, and improve methodologies.
• Exceptional communication skills, with the ability to explain sophisticated quantitative concepts in a clear and engaging way.
• Proven ability to manage multiple priorities and thrive in a dynamic, fast-paced environment.
