Python Engineer

[Employer hidden — sign up to reveal] - London - Full Time (Permanent) - Hybrid - Data Science Central

About the role

We'd love for you to become a key part of our Python Infrastructure team; a collaborative group that's always pushing the boundaries of what's possible.

In this role, you'll get to do it all: designing and integrating powerful new APIs that genuinely improve our customers' experience, optimising our lending platforms for performance and scale, and diving into the kind of deep architectural conversations that engineers get excited about.

No two days look the same here.

We're building something great, and we're looking for the right people to grow with us. If that sounds like you, we can't wait to hear from you.

Our Tech Stack

Our stack is built on Python and FastAPI, deployed via Docker and Kubernetes on AWS, with ArgoCD handling our continuous delivery pipeline.

What we’re looking for

  • Strong, modern Python development experience
  • A good understanding of a modern web framework - FastAPI
  • Strong automatic testing skills (unit, integration, functional)
  • A keen desire to want to learn and input into a highly collaborative team
  • If you’ve worked in a cross functional environment, it would be a plus but not needed

Interview process

  • A quick phone call with one of the team
  • A short coding exercise to complete in your own time
  • Technical Video Interview for 60 mins
  • Meet the team you’ll work with daily
  • Culture interview for 30mins
  • Final Interview
