C# Developer

C# Developer | £500/day - £700/day | Immediate Start | London & Remote

We are looking to hire a team of Developers, initially for a 6-month contract renewal on a 2-year program.

This is a hybrid-working contract with an expectation of being in a London based office a couple of times a week - however, our client-partner will also consider full remote working.

We have various roles with the need for C#, REST, and Python experts and any Angular and/or Docker experience & capability is a plus.

Just so you are aware, a number of recent interviewees failed to answer basic questions in C# and SQL.


An in-house .NET based application layer integrates the inhouse proprietary systems.

The team is focused on building simulation-based pricing systems for Middle and Front office.

The core technologies utilised within the team include C# .NET and Microsoft SQL Server running on Windows however our client is now increasingly moving towards C# .NET Core and Python running on Linux operating systems utilising Docker containers to allow future cloud migration.

The ideal candidate would be a senior C# .NET developer with exposure to pricing or simulation-based risk systems in the past.

Knowledge of derivative and cash based products is desirable but there is no requirement to have in depth understanding of how these are priced.

You will be able to understand functional requirements and translate these into technical solutions.

Knowledge of Docker, Python, Hadoop and Azure would be a bonus.


The ideal candidate will be able to design solutions for middle office risk management systems and related products, providing clear technical scope and test documentation, whilst coordinating change control, including software management, testing and production releases.

Developers competent with C# and Microsoft development stack (WCF, WF, Unity), Microsoft SQL Server, Software design methodologies and best practices, as well as end to end development cycle knowledge are likely to receive an immediate interview request.

Experience of working in an investment banking (or similar) technology environment would be desirable.


- Experience with Microsoft HPC Server, Grid and Cloud Computing.

- Web Development with ASP .NET and MVC.

- Continuous integration with TeamCity.

- Knowledge of Microsoft Azure.


Developers with a proactive, motivated approach and an Agile and flexible approach to delivery, who are also results driven, with a strong sense of accountability - able to prioritise and structure their own workload according to delivery requirements will be of interest.

This is an immediate job opportunity for contractors with strong decision-making skills, and the ability to demonstrate sound judgement, with excellent attention to detail and accuracy.

Financial knowledge or having worked for investment banks - with any financial instrument knowledge would be a bonus.

Experience of interacting with quantitative users to resolve complex business problems and strong problem solving skills, numerical skills and an analytical mind-set will hold you in good stead.
