Date: 19 May 2026

Requisition ID: 1702947

We have an opportunity for agile, market‑savvy professionals in quantitative & financial risk and modelling. The focus of our team is on credit risk modelling, banking credit risk regulation, market risk modelling and (derivative) valuation, and derivatives instruments. We look to strengthen our team with Senior Consultants with a solid knowledge in one or more of these fields.

The Belgian Risk practice acts as a center of excellence within the EMEIA region with respect to quantitative modelling. Among others, this means we have a robust and broad expertise in the practical aspects of credit modelling. Together with our equally eminent colleagues of the Data & Analytics team, we also work on Machine Learning applied to credit risk as well as climate risk modelling for financial institutions as part of our sustainable finance workgroup.

On top of this continuous learning from local and international experts, we have developed an internal credit risk modelling program and an internal derivative valuation program. Both programs consist of a mix of face‑to‑face trainings, web‑based learning and on‑the‑job training.

In Market Risk, we work on topics such as:

• Capital Requirements Related (CRR): Regulatory topics – Fundamental Review of The Trading Book (FRTB), Interest Rate Risk in the Banking Book (IRRBB) and underlying models like pre‑payment models
• Stress‑Testing: Analysis and definition of stress‑scenarios related to Market Risk Factors taking into account their statistical properties

Vanilla / complex derivatives (Multi-Asset / Path-Dependent / Skew Sensitive), credit and funding valuation adjustments, illiquid bond pricing. Also, prudent valuation is an important topic that is covered by the team.

The team also supports IFRS13 projects when it comes to the definition of Fair Value Levelling / Assessment of Observability of Input Parameters.

Aside of these purely technical areas, the team covers the review of Model Governance Frameworks as well, how institutions identify, monitor, measure and mitigate Model Risk, in particular for Pricing Models and Market Risk Capital Models.
