Senior Backend Developer (x 2)

At Kolleno
London, UK (or remote)

About the role

We’re hiring for two Senior Backend Developers to help us build the future of late payments collection.

You’ll be joining us right at the start of our development to deliver a truly unique B2B late payment technology, and we want you here for the long term with stock options. We’re looking for someone ambitious to come and own setting up Kolleno growth function – working directly with experienced founders and senior team who have worked at large international corporates (i.e. Expedia.com, Goldman Sachs).

You’ll join a fast-paced team where you’ll be testing, learning, and iterating as fast as you can. We’re looking for someone data-driven and curious, who can ruthlessly prioritise and focus. You will need a strong sense of initiative.

About The Company 

Our mission is to help every business to get paid on time. It is a crippling issue across all industries that nobody has managed to solve… until Kolleno arrived.

We’re building the future of cash management for companies: from invoices chasing to payments reconciliation. The full cycle is done through Kolleno, promising exponential growth in the FinTech arena.

We’re optimistic, hard-working, full of energy, and creative. We’re looking for like-minded people who want to be part of a once in a lifetime adventure.

What You’ll Be Doing

You will build the backend of a greenfield project, our new Kolleno product. It includes structure, design, and API endpoints to be used by the frontend team.

You will write code that is vital to the company growth, by coordinating with multiple teams: founders, data science, frontend, sales, marketing, and account management in order to fully understand what the final result needs to look like.

You’ll be joining a small, dynamic team. We want a real team player, who is flexible to support things that are outside of their role as you will take on more responsibility as the team grows.

What We’re Looking For

– 2+ years programming experience with Python

– Understanding of APIs (web services)

– Willingness to step forward and suggest ideas, comments, remarks

– Django framework expert

– Django REST Framework and AWS experience are nice to have, but we’re happy to help you with learning them on the job

Technologies We Use

Core Technologies: Django Rest Framework, PostgreSQL, AWS Lambda

Supporting Libraries: Pandas, OAuthlib (among many others!)

Testing: strong testing culture with pytest
