QRS has openings for Officers and Assistant Vice Presidents (depending on experience) in the following departments in its Warsaw office:
Counterparty Risk Analytics (CRA)
The CRA team is responsible for developing and maintaining the methodologies to calculate counterparty credit risk exposures of OTC derivatives, exchanged-traded derivatives, security financing transactions, and margined loans. The models are used for advanced Basel regulatory capital calculations, CCAR/Internal Capital Adequacy Assessment Process (ICAAP) estimations, and internal risk management measures (PFE/EPE).
Additionally, the team provides live-deal analysis to business and risk management by calculating credit exposure factors at trade and portfolio levels, estimating allowable collateral levels, and determining initial margin requirements. The team also conducts impact analysis for capital optimization initiatives and new regulatory rules related to counterparty risk, and ensures models and data logics are implemented correctly in credit risk systems.
Credit and Obligor Risk Analytics (CORA)
The CORA team is responsible for covering enterprise-wide model development for wholesale and retail credit risk. CORA models are used to estimate advanced Basel III regulatory capital parameters and Global Systemic Stress Testing.
On the retail side, CORA plays an oversight role on Basel III exception adjustments and Basel III model performance. Additionally, CORA provides support for Retail Risk Weighted Assets (RWA) Stress Testing for CCAR.
On the wholesale side, CORA models produce the CCAR and ICAAP estimations. Other wholesale models cover loan loss reserves (IFRS 9/ CECL), cost of credit, obligor risk ratings (debt rating models), liquidity stress testing, RWA stress testing, and market-based default and downgrade risk models.
CORA is also responsible for approval of all risk rating policies and processes for wholesale portfolios.
Market Risk Analytics (MRA)
The MRA team is responsible for developing and maintaining market risk models used for both risk management and regulatory capital purpose. These models currently include Value-at-Risk (VaR), Stressed VaR (SVaR), Incremental Risk Charge (IRC) for trading book migration and default risk, and Comprehensive Risk Measure (CRM) for credit correlation trading.
The team also maintains the Citi Market Risk Exposure Specification, which provides a set of consistent risk sensitivity measures across the firm. In performing the ongoing calibration of the market risk models, the team also specifies, collects, verifies, and maintains historical time series of the market factors. Additionally, the teams mandate includes obtaining approval on market risk models for Basel regulatory capital calculation, preparing Citi for future regulation changes (e.g., Fundamental Review of the Trading Book), and provides quantitative analyses and support to Market Risk Managers.
Risk Capital Analytics (RCA)
The RCA team is responsible for defining the overall framework and principles of Risk Capital (RC) across market risk, wholesale and retail credit risk, pension risk, and ALM risk. RC is a firm-wide metric to measure economic capital usage at the consolidated group as well at the detailed business unit level. It is reported to regulators and the Board as a key capital adequacy metric for Citi and its major legal entities. RC is also used extensively to set risk limits and to assess the risk-adjusted profitability of large transactions.
Regional Stress Testing
The Regional Stress testing team focusses on the end-to-end delivery of non-CCAR related cross-risk-stripe regulatory stress tests and ICAAPs in the Europe, Middle East, and Africa (EMEA) region. The EMEA region houses some of the most sophisticated trading and banking books outside of the Citibank North America branch network, and the team specialises in virtual collaborations with in-country Risk/Finance, and infrastructure teams globally to overlay the local regulatory framework, local accounting standards, and emerging regulatory expectations on the central core capabilities provided by Citi.
