About Us At Xelix, we work with some of the world’s largest companies to automate and strengthen their financial controls. Our AI solutions redefine how Accounts Payable teams operate — moving from manual processes to automated, intelligent workflows. Xelix is a fast‑paced scale‑up; things move fast and expectations are high. We raised our Series B with Insight Partners in June 2025 and are expanding aggressively while remaining profitable. We have over 100 talented people pulling together to achieve our goals. Everyone is trusted to take ownership, move fast, and have a meaningful impact. We prioritise personal and professional growth, keep things fun, and love to celebrate a milestone together.
About the Role We're seeking Mid and Senior Python Developers to join our back‑end development team. This is a varied and challenging programming role. Tasks may include writing code to manage incoming data, working with AI Engineers to analyse huge data sets, or writing RESTful APIs in Django to support the React front end. Our ideal candidate takes pride in their work — producing clean, tested, beautiful code. Rather than give you a detailed set of requirements, we encourage engineers to take responsibility for solving the problem. There are many opportunities to innovate as you collaborate with stakeholders to design and implement new features.
You will be well supported to continue your professional development. This includes an annual conference allowance, a budget for books, and a monthly session with your manager to identify and track your learning goals. As Xelix continues to grow, opportunities for you to develop your career — becoming a Team Lead, Project Lead, or Staff Engineer — could be available to the right candidate.

Implementing robust and scalable solutions in Python.
Developing, using, and designing REST APIs to efficiently deliver application components.
