Job Category: Technology
Potential Referral Amount: 6250 Argentine Peso (ARS)
Kapital is the Pricing and Risk Management system used by Global Rates Markets and Global Emerging Markets. Kapital supports a wide range of products, from vanilla IR Swaps to complex Rates Exotics and Hybrids products. Kapital manages the full lifecycle of the trade, from trade booking (or processing of STP) to feeding Confirmations and Settlement systems. It is used to produce the risk (SOD, EOD and Intraday) used by the Trading desk to manage their position in addition to calculation of P&L actuals for the trading desk every day. Kapital is also responsible for feeding corporate systems (Market Risk, Regulatory, Collateral).

Kapital is written in Smalltalk and integrates an object database (GemStone) as its persistence mechanism. The application has continuous build and integration processes with a single global codebase combined with automated nightly regression tests. The customised IDE is integrated within the application and allows for full code management and debugging capabilities.


Team Overview:

Approximately 90 Kapital developers are located across New York, London, Glasgow, Mumbai, Hong Kong and Tokyo.  The team is split in to infrastructure, financial development and test & release functions. In primary site locations (London, NY, HK, Tokyo) the financial AD teams will often be seated directly with the application users & trading whilst secondary sites (Glasgow, Mumbai) support users in other regions remotely.


This role is for a financial developer to support the Rates and Emerging markets businesses which have trading desks across the globe encompassing not only different currencies and products but also varied regulatory environments.
Working as part of a distributed team, the candidate will need to work closely with the business and technology stakeholders to complete and own tasks from inception through to delivery.  Tasks will include building out new functionality and extending existing features as well as providing support to the Kapital users, from both front office (Trading, Structuring, Sales) middle office (Trade Support, Finance) and several technology groups that own applications that consume data from Kapital. This will also involve participation in a production support rota to cover key business processes.

The role is in a fast paced environment thus the candidate must be able to adapt quickly to evolving requirements and drive their tasks to completion whilst working in an agile development environment.



  • The candidate should have an understanding of an object oriented programming language (e.g. Java, C++, C#, Smalltalk) and their underlying principles
  • Data modelling
  • Code version control
  • Understanding of coding optimisations
  • Enthusiasm for increasing knowledge of financial markets and products is essential
  • Willingness to adopt and contribute to an agile development process
  • Clear communication
