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. We have a team of 150 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.

In this role you’ll grow, be challenged and help shape the future of Xelix. If you’re excited about building something special with us, we’d love to hear from you.

About the role

We're seeking Senior Python Developers to join our back-end development team.

This is a varied and challenging programming role. Tasks could 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.

What you'll be doing

Implementing robust and scalable solutions in Python.
Developing, using and designing REST APIs to efficiently deliver application components.
Implementing performance improvement strategies.
Ensuring the quality of code by writing comprehensive tests and participating in code reviews.

What you’ll bring

4+ years of Python coding professional experience
Ability to learn and apply new technology quickly
Ability to effectively communicate complex technical concepts to team members and stakeholders.

Familiarity with coding in Django and the Django Rest Framework, or Flask Web frameworks
Degree in Computer Science (or similar), at 2:1 or above
Amazon Web Services
SQL / PostgreSQL
Build pipeline and CI with GitHub, Jenkins, Docker, Terraform

What we offer in return

Competitive salary of £70,000 - £95,000 depending on experience

️ 27 days of annual leave (including 3 days Christmas closing) which increases up to 3 days based on tenure, with the option to roll over, buy or sell up to 3 days

Hybrid working with one day a week from our dog-friendly Hoxton office

On-site gym and cycle to work scheme

️ Employee discount at over 100 retailers

Comprehensive private medical & dental cover with Vitality

Enhanced parental leave pay

Learning & development culture – £1,000 personal annual budget

We’re carbon-neutral and are working towards ambitious carbon reduction goals

Lots of team socials & activities

️ Annual team retreat

We believe that people from diverse backgrounds, with different identities and experiences make our company and product better. No matter your background, we'd love to hear from you! And if you have a disability, please let us know if there's any way we can make the interview process better for you - we're happy to accommodate!

If you're a recruiting agency - we have an existing list of agencies we work with and we are not currently planning on expanding the list. Neither the Talent team nor hiring managers or the Support team will respond to cold outreach.

This is a full-time position, with standard working hours from 9:00 AM to 6:00 PM, Monday through Friday.

Interview Process
While the exact process may vary slightly depending on the role, our typical interview stages are:

Introductory Call – A short Teams conversation with a Talent Partner to discuss your background and the opportunity.
Hiring Manager Interview – A 30–45 minute Teams meeting to explore your experience and fit for the team.
Technical Task or Presentation – A role-relevant exercise to demonstrate your skills and approach.
Final On-site Interview – An in-person meeting with our senior leadership team and co-founders at our office.

We strive to make the process clear, efficient, and respectful of your time.

We welcome the responsible use of AI for research and interview preparation, but ask that it isn't used to generate answers during live interviews. We also believe in being transparent - we use Metaview's AI note-taker during interviews so our interviewers can stay fully present. If you'd prefer us not to use it, just let your interviewer know. While you may need to answer eligibility questions as part of your application, we do not use AI to review or make decisions on applications - every application is reviewed fairly by a member of our Talent team.
