The Team

We are spinning up a US-based technology team for Man Varagon that will be part of Man’s Alternative Discretionary Technology team.  The new team will initially be focusing on integration and automation of deal pipelines, data flows and report generation, leveraging the best tools available from Man’s technology platform.  There are large gains to be made quickly in the data and workflow management space which will dovetail into building quant tools to provide high quality underwriting and oversight of our credit portfolios. 

Alt Discretionary is a small and agile team that works very closely with the front-office teams in the UK as well as the US for Man’s discretionary strategies that operate in non-traditional markets.  We develop and support a number of platforms for underwriting and ongoing management of private market assets like buy-to-rent housing portfolios, real estate debt and credit risk.

Quant technology in private and alternative markets is a rapidly growing space in which Man is demonstrably on the cutting edge so there are opportunities here to make significant contributions in shaping this alongside the investment teams.

The Role

This is a senior engineer role to lead the new team from the US, working side-by-side with the portfolio managers and in collaboration with the wider Discretionary tech department in the UK.
