Elfin Market - Backend Developer

About Elfin Market

We’re a young fintech start-up which aims to disrupt the credit card market in the UK. We use peer-to-peer lending – that is, we directly connect borrowers and lenders without costly banking intermediaries – to offer a cheap alternative to credit cards to our borrowers and solid returns to our lenders (we’re actually the first peer-to-peer lending platform in the world to offer flexible credit akin to a credit card). We are currently preparing to launch a beta version of our platform. We’re currently a team of three, including our two co-founders, and we’re looking for a motivated and ambitious back-end developer to join us in our exciting journey.

Your role

You will be working in close collaboration with our co-founders on all aspects of our back-end systems. This will include writing server-side applications and user APIs, improving the overall design of our back-end architecture, writing testing and reporting tools, as well as maintaining and improving our existing codebase. You will be expected to write scalable, testable and efficient code, while being mindful of security and data protection risks.

We plan to launch several new features in the coming months, you will have a key role in their development and will be involved in all steps of the process.

The ideal candidate

We’re looking for someone with the following profile:

  •  Expert in Python and Django

  •  Experience designing and implementing back-end systems of web applications

  •  Extreme motivation: as our first back-end developer, we’re looking for someone who will be as involved as Elfin Market’s co-founders themselves and who will get things done.

  •  Open-mindedness: we love discussing ideas and exchanging constructive criticism, especially before taking any major decision for the firm. You’ll be a key part of those exchanges.

  •  BSc/MSc in Computer Science, Mathematics or a related subject

Additionally, if you tick any of the following boxes, this will be a definite plus:

  •  Experience building RESTful APIs with Django REST Framework

  •  Some knowledge of front-end web development technologies: HTML, CSS, JavaScript

  •  Familiarity with the AWS ecosystem

  •  Experience working in a tech start-up


  •  Working in an early stage start-up will give you the opportunity to acquire lots of different skills and grow your role over time beyond its initial scope.

  •  Really cool working environment at Level39, London’s largest fintech accelerator, which provides great views over Canary Wharf, free teas and coffees, freshly baked cookies every day and ping pong tables!

  • Flexible working arrangements

  •  Your very own MacBook

  •  Competitive compensation package, which includes shares in the company
