About the Role:

Our screening team is responsible for sanctions, PEPs (Politically Exposed Persons) and Adverse Media screening.

The screening team has a name matching service that is routinely tested against an internal benchmarking suite, and annually against external benchmarking suites.

We are looking for someone to own the testing, tuning and optimisation of these matching algorithms. The candidate will own this function - be responsible for the overall testing and tuning strategy, deep dive testing results, understanding how to optimise rules for efficiency and effectiveness and create rules for complex controls.

Here’s how you’ll be contributing:

Automatising algorithm testing on real customer data as well as synthetic data. Packaging the service into a library or deploying it to staging or production environments

Analyse results from exact name matching and fuzzy name matching against internal and external benchmarks

Identify and categorise types of missed cases and map those to known or new issues

Propose technical solutions to reduce the number of missed cases identified

Design an internal test set to evaluate both the precision and recall of the screening engine

Align performance on the test set with real-life production performance

Extend internal benchmarking to new scenarios for better coverage of screening algorithms

Define an overall strategy for testing and tuning

Evaluate the use of an internal benchmarking tool

Evaluate testing capabilities of external vendors in the market to define the most effective method of continuous external benchmarking, processes of governance

Tailor business rules to reduce hit rate, prepare tuning data, reviewing hit reduction strategies and work with product managers, compliance and engineers to ensure roadmap alignment

Tweaking engine configuration to find the sweet spot for precision and recall.

Provide answers on how many historical true positives we would miss based on different optimisations

Work on advanced rules for complicated controls, such as vessel screening

Uncover and action on opportunities to help the Screening operational team scale

Automatising or creating solutions to assist operations in their work

Modify existing tooling introducing LLM assistants to improve the efficiency of agents and speed of case resolution

A bit about you:

Experience implementing, testing and evaluating performance of multiple rules across systems;

Strong Python knowledge. Ability to read through code, especially Java. Demonstrable experience collaborating with engineering on services;

Strong algorithmic design and testing skills. A big plus for proven experience with name matching algorithms;

Experience with statistical analysis and good presentation skills to drive insight into action;

A strong product mindset with the ability to work independently in a cross-functional and cross-team environment;

Good communication skills and ability to get the point across to non-technical individuals;

Strong problem solving skills with the ability to help refine problem statements and figure out how to solve them.

Some extra skills that are great (but not essential):

Familiarity with automating operational processes through technical solution, for example Large Language Models;

Knowledge of Sanctions and Name Screening Optimisation and Tuning

Experience working in a heavily regulated business domain.
