About The Company
Five Sigma Finance is a central London-based investment and technology start-up that delivers innovative solutions in the fixed income space. We specialise in credit markets, offering advisory and transaction support services across the entire investment lifecycle for public and private fixed income assets.
Our business product is focused around an in-house built, scalable and secure SaaS platform named Abide. Abide enables institutional investors to efficiently manage and monitor structured finance portfolios. The platform delivers clarity, control, and automation across complex fixed income asset classes. As an intern in the tech team, you would get hands-on experience in further developing and maintaining this platform.
For context; as the company has grown, we have taken on-board a handful of Software Developer interns to-date, and their contributions to the team’s development has been highly valued. Therefore, based on this successful model, we are looking to bring on a brand new addition to the team.
This opportunity will present you with the chance to work on greenfield projects and receive quality mentorship, as your career goals develop.
