FRTB Engineer: implementing and operating the internal model calculation
An FRTB Engineer implements and operates the engine that computes market risk capital under the internal model approach (IMA) of FRTB: the Expected Shortfall per trading desk, the liquidity horizons and the stress scenarios. It is a scarce intersection of market risk, numerical engineering in C++ or Python and the operation of massive workloads on grid or HPC.
What they do / responsibilities
- Implementing the IMA engine — codes the Expected Shortfall calculation per desk, the liquidity horizons and the aggregation of modellable and non-modellable risk factors.
- Numerical optimization — writes the hot path of the calculation in C++ or vectorized Python so the close fits within the available window.
- Distribution across the grid — spreads the load over thousands of tasks on IBM Spectrum Symphony, Slurm or equivalent orchestrators.
- Backtesting and P&L attribution tests — instruments the tests the regulator requires to retain internal model approval per desk.
- Operating the close — monitors the daily run, diagnoses deviations and ensures the traceability of figures.
Why it is scarce / why it matters in banking
The role brings together three competencies that rarely coincide in a single person: an understanding of the Basel market risk framework, command of high-performance numerical engineering and experience operating distributed workloads at scale. In investment banking, retaining internal model approval per desk over the standardised approach (SA) can mean a material difference in capital, and that approval depends on the calculation being correct, reproducible and delivered within the close window. An engine that fails backtesting or does not finish on time directly erodes the capital base.
