You will serve as Head of Risk, owning and developing the firm's risk function end-to-end. This is a senior leadership role with direct accountability for designing, implementing, and enforcing a firm-wide risk framework across all activities. You will report to the COO and work closely with the CIO to co-design the firm's risk architecture.
Key responsibilities include:
• Develop and maintain a quantitative risk framework grounded in modern risk theory, including market, credit, liquidity, and systemic risk modelling, with emphasis on tail risk, extreme value theory, dependence structures, and stress testing.
• Co-design and implement a firm-wide risk management system including data architecture, risk aggregation layers, real-time monitoring capabilities, and reporting infrastructure across all business lines.
• Build an integrated risk view across centralized and decentralized venues, covering exchange risk, counterparty risk, smart contract risk, collateral efficiency, and liquidity fragmentation.
• Define and implement advanced risk metrics (VaR, Expected Shortfall, stress scenarios, liquidity-adjusted risk, concentration risk) and ensure consistent application across trading, treasury, and investment activities.
• 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 such as oracle and protocol risk.
• Set the standard for risk culture, challenge the business, and enforce disciplined risk-taking while enabling the firm to scale.
You will have full oversight of risk across trading (spot and derivatives), treasury, and investments, including exposures across CeFi and DeFi environments.
The role offers autonomy in time management with semi-flexible working hours, annual team retreats, and a fast-paced, intellectually stimulating environment. Keyrock is committed to building an inclusive, diverse, and non-discriminating workplace.
REQUIREMENTS:
• Strong foundation in quantitative risk management with hands-on experience in market risk, credit risk, and liquidity risk modelling, ideally aligned with frameworks such as those in Quantitative Risk Management (McNeil, Frey, Embrechts).
• Demonstrated ability to design and implement risk models, including tail risk estimation, scenario analysis, stress testing frameworks, and dependence modelling across asset classes.
• Proven experience designing or co-designing firm-wide risk systems, working closely with technology and operations teams to translate risk requirements into scalable infrastructure.
• Experience operating at the intersection of traditional financial markets and digital assets (CeFi and/or DeFi), with strong understanding of differences in market structure, risk transmission, and infrastructure.
• Practical knowledge of crypto-specific risks, including exchange/custodian risk, smart contract risk, protocol risk, funding/basis dynamics, and collateral management in both centralized and decentralized environments.
• Strong drive and proactivity to continuously strengthen risk management in a fast-growing financial institution.
• Self-aware, fiercely passionate, mission-driven communicator with proactive ownership, commercial mindset, and pragmatic flexibility.
