At Caspian One, ‘Core Development’ is the title used to represent our developer communities, as located throughout the UK’s financial markets. Our focus can be categorised into three distinct client types - Buy Side | Hedge Funds and Asset Managers, Sell Side | Investment and Commercial Banks, and Innovators | FinTech’s and Start ups.

Front office development is our primary area of specialism, but not exclusively - with typical permanent, contract and project-led positions including work on trading and/or pricing systems, risk engines, portfolio management systems, regulatory requirements, libraries, infrastructure, quantitative areas and more. 

The people in our Core Development network are highly experienced and credible professionals; with in-demand skill sets that see them ranked amongst the top 10% of tech talent in the market today. We are seeing an increase in demand from Cloud, Big Data and Machine Learning technologies.

Java, C#, Python, JavaScript - skills in these languages (particularly when combined with Cloud technology capabilities), are commonly the most requested by clients; along with, but to a lesser extent, C++, KDB and Golang. Zack Keane, under the management of Phil Staples, have ownership of the Core Development market - with Zack specialising in Java & C++ and both supporting the C#.NET communities.
The Core Development market is presently undergoing a reduction in greenfield projects, with buy and sell side clients both looking to overcome mandatory, regulation-led projects rather than investing in new technologies and methods to improve performance. The main regulatory drivers include Brexit, LIBOR, post-MiFID II (ongoing) and post-GDPR (ongoing).

This reduction is lessened within our innovator clients; FinTech’s and Start ups - which is one reason we’re seeing developers, motivated by a wider variety of factors, drawn to projects that are perceived to be more fulfilling. 

IR35’s 2020 advance into the private sector is also beginning to have an impact on the availability of contract vacancies, as risk-averse financial institutions look to avoid any financial liabilities associated with inside/outside IR35 assessments. (For information on IR35, see our interview with Seb Maley, CEO of Qdos Contractor at LINK). One answer for our clients is Caspian One’s Partnered Capabilities service, offering an adaptive solution for project-led staff augmentation. Read more at LINK

I have used Caspian One for some of my more crucial, time critical projects where we were under extreme pressure to deliver.
