Actuarial Technology

Insurers and pension funds run calculations that are large, complex, and business-critical. Many of these calculations still run on legacy systems that are slow, hard to maintain, and difficult to audit. Actuarial technology projects exist to modernise this infrastructure, making calculations faster, more transparent, and easier to validate.

The daily work involves understanding existing actuarial models and processes, rebuilding or extending them in modern programming environments, and making sure the new implementation produces the same results as the old one. Writing tests, documentation, and code that other actuaries can maintain is a central part of the job. You work closely with actuaries who understand the business logic and with IT teams who manage the infrastructure.

The main tools are Python, which is increasingly used to replace legacy actuarial software, and version control systems like Git. Actuarial software such as Prophet or MoSes may be involved when working on life insurance or pension models. Knowledge of actuarial concepts such as liability valuation, cash flow projection, and capital modelling is important for understanding what the code needs to do.

The work sits within the Actuarial Sector and connects closely to the Actuary and Data Engineer roles. It is common at insurers, pension funds, and actuarial consultancies that are modernising their calculation infrastructure. The combination of actuarial knowledge and software development skills makes this a relatively specialised type of project.
