Senior Pricing Quantitative Developer

We are looking for a senior Pricing Quantitative Developer to lead Fortum’s pricing modelling development.

In this role, you will design, develop, and validate quantitative pricing models used for pricing physical electricity products, structured customer contracts and electricity derivatives. Your work will sit at the intersection of financial engineering, power markets, and asset modelling, supporting both standardised products and complex, bespoke customer cases.

You will work closely with Pricing, Portfolio Management, Product Management, Corporate Risk, and application developers to ensure pricing models are robust, commercially relevant, explainable, and suitable for operational use through Fortum’s pricing platform.

Unlike a traditional pricing quant role, your work is also closely related to Fortum’s asset modelling capabilities. Asset behaviour under varying price scenarios is a core building block for deriving pricing models for RES and hybrid portfolios.

About the role

As senior Pricing Quantitative Developer you will:

• Design and develop quantitative pricing models for electricity products and tailored customer contracts.
• Translate product terms, pricing mandates, and hedging principles into robust quantitative model formulations.
• Apply financial engineering and numerical methods (e.g. stochastic modelling, Monte Carlo simulation, calibration techniques).
• Assess model stability, sensitivity, and limitations across market regimes and scenarios.
• Contribute to the development and evolution of asset modelling under price scenarios as an input to pricing.
• Collaborate with Portfolio Management & Pricing to reflect hedging logic and risk treatment correctly in pricing models.
• Engage with Risk to support independent review, validation, and approval of pricing models.
• Document models clearly to support governance, auditability, and downstream implementation.
• Support application developers during the integration of approved models into operational pricing tools.

About you

You bring:

• Strong background in mathematical modelling, especially regarding probability theory and stochastic processes.
• Experience applying numerical methods in a pricing or valuation context.
• Familiarity with non-linear payouts
• Familiarity with MILP, preferably applied to power markets
• Strong Python skills for quantitative modelling and analysis.
• Solid understanding of energy pricing concepts and key risk drivers.
• Ability to explain complex models and assumptions clearly to non‑specialists.
• A structured, ownership‑driven way of working.

It is an advantage if you have experience with:

• Experience with Nordic power markets
• Experience with asset modelling, optimisation, or scenario‑based valuation.
• Familiarity with forward curves
• Production‑grade quantitative development practices (testing, packaging, documentation)
