What we are looking for

We are seeking a Head of Risk to own and develop the Firm’s risk function end-to-end. This is a senior leadership role with direct accountability for the design, implementation and enforcement of a Firm-wide risk framework across all activities.

The role requires strong quantitative risk expertise and the ability to apply rigorous methodologies to complex, real-time markets across both traditional finance and digital assets. The successful candidate will co-design the firm’s risk architecture with the COO and CIO, covering data, analytics and real-time risk aggregation.

You will have full oversight of risk across trading (spot and derivatives), treasury and investments, including exposures across CeFi and DeFi environments. This includes defining risk appetite, implementing advanced risk metrics and ensuring disciplined risk-taking across the organization.

We are looking for a leader who sets the standard, challenges the business and enforces a strong risk culture, while enabling the firm to scale.

Role description

Quantitative Risk Framework: Develop and maintain a quantitative risk framework grounded in modern risk theory (e.g. market, credit, liquidity and systemic risk modelling), leveraging concepts such as tail risk, extreme value theory, dependence structures and stress testing

Is plus: TradFi ↔ Crypto Risk Translation: Translate traditional financial risk methodologies into crypto-native environments, adapting models to account for 24/7 markets, fragmented liquidity, funding dynamics, on-chain transparency and new failure modes (e.g. oracle risk, protocol risk).

Background and Experience

Quantitative Risk Expertise: Strong foundation in quantitative risk management, including hands-on experience with market risk, credit risk and liquidity risk modelling, ideally aligned with frameworks such as those presented in Quantitative Risk Management (McNeil, Frey, Embrechts).
