This is a full-time position at grade 4/5 for which the EIB offers a permanent contract.
Internal benchmark (Associate) Officer Business & Process Analysis
Panel interviews are anticipated for April/May 2026
Purpose
The Quantitative Implementation Unit (FI/SPBS/- /QI) supports FI in the design, implementation and evolution of quantitative models covering treasury, capital markets and the financial management topics handled in the 1st Line (e.g. interest rate, FX, liquidity and counterparty credit risks).
Operating Network
You will report to the Head of Unit and work under the supervision of senior colleagues. Day- to- day delivery combines business analysis discipline with quantitative development skills to translate policy/methodological objectives into usable, controlled solutions that operate reliably in production.
You will work closely with FI/SPBS divisions (FPM for methodological and policy aspects, OSM for operations/production, SDM for systems and data), with GIS/IT for industrialisation and architecture, and with Risk Management, Financial Control and Internal Audit on governance, validation and assurance.
Key Features Of The Role Include
End- to- end delivery from discovery to controlled production (requirements → data → prototyping/specification → testing/validation → release → run), often across multiple systems and teams.
Control consciousness: ensuring evidence (reconciliations, approvals, logs) and documentation meet expectations and are audit-ready.
Stakeholder alignment across business, IT and control functions, balancing methodological rigour with operability and timelines.
Strong collaborative spirit and cross directorate teamwork: active participation in mixed delivery squads (FI + Risk Management quant developers, supported by GIS/IT), operating with shared standards and backlogs while respecting independence across the Lines of Defence.
Continuous improvement to enhance robustness, performance, user experience and process simplicity where feasible.
Accountabilities
Implement and maintain quantitative models supporting FI activities and strengthening the 1st line of defence within FI, in line with industry standards, market practices (e.g. valuation and xVAs, ALM/IRRBB metrics, Fund Transfer Pricing). Support in the design and evolution of these models.
Elicit and structure business needs by capturing objectives, constraints and acceptance criteria; produce clear, testable functional and non-functional requirements; ensure end-to-end traceability from requirement to controlled production.
Engineer and analyse data: source, reconcile and quality-check inputs; design robust data queries and controls; perform exploratory analysis; produce decision-ready outputs (dashboards, reconciliations, exception reports) for business and control stakeholders.
Prototype and specify solutions: develop lightweight analytical prototypes (e.g. Python/Excel/SQL) to validate concepts and performance; prepare functional and technical specifications for industrialisation by GIS/IT and/or vendors; ensure alignment with architecture and security standards.
Test, validate and evidence controls: define test strategy and cases; coordinate UAT and defect triage; support back-testing and independent validation; embed control evidence (4-eyes, reconciliations, run logs.
Deliver change and manage stakeholders across FI/SPBS divisions and GIS/IT and partner functions (Treasury, Risk Management, Financial Control, Internal Audit); run workshops.
Document and maintain methodologies, assumptions, model/process changes, test results and user guides to an audit-ready standard; contribute to consolidation and rationalisation of models and applications.
Support production and continuous improvement: monitor runs, analyse incidents to root cause, and implement enhancements that improve stability, performance, controls and user experience.
Represent the Division in working groups and committees as requested; advise FI colleagues on the above-mentionedareas; prepare opinions and technical briefing notes.
Support innovation adoption: identify opportunities to apply innovative technologies (e.g. AI assisted analysis, coding, testing and document intelligence), run focused proofs of value, document benefits and risks, ensure compliance with internal controls and, and prepare clear specifications for industrialisation with GIS/IT.
