Job Description:

We are working with a highly successful FinTech firm that delivers derivative pricing tools and analytics for traders at hedge funds and investment banks. Due to sustained success, the firm are looking to add a Software Engineer to help support their growth. This role would suit an individual with experience within the financial space, working with large, abstract, code bases and agile environments. Data is central to their value proposition, so this is an incredibly important role.

The firm work largely remotely with regular (weekly) in person sessions to develop and maintain their progressive culture and to help support personal development. They are based in London but the team, at large, are across the UK. Team members are trusted to take on responsibility, so there is no micromanagement. This will suit a SWE, comfortable across the stack, who is happy working independently but in a collaborative team-based approach. This role will involve working within a small firm that is dedicated to delivering derivative pricing analytics via a web app. The client base consists of traders at leading hedge funds and investment banks. Their ever-increasing popularity is due to them being able to deliver accurate prices quicker than other systems.

What we are looking for:

• A software Engineer with experience working with large, complex code bases that has the ability to write ‘collaborative’ code
• Experience working in a collaborative team but also demonstrable ability to work independently due to the remote nature of the role
• Web technologies experience (WASM, WebGL), as well as Typescript, Rust and V8
• Ideally an undergraduate degree in a relevant STEM subject, such as Comp Sci
• Exposure to functional programming, pair programming and agile methodologies
• Some product knowledge within Rates/FX or Equity derivatives
• Familiarity with financial derivatives and pricing would be advantageous
