ABOUT JIGSAW FINANCE
Jigsaw Finance is a UK-based vehicle finance broker. We work with a substantial panel of motor finance lenders to serve customers across all credit profiles — from those with excellent credit ratings through to customers with adverse history who have previously had difficulty obtaining finance.
Due to ongoing growth, we are looking to recruit an additional Software Engineer to join our engineering team. The successful candidate will help maintain and improve our existing systems while contributing to the development of new projects.
