Lead Python Engineer

About Lendable

Lendable is on a mission to build the world's best technology to help people get credit and save money. We're building one of the world’s leading fintech companies and are off to a strong start:

One of the UK’s newest unicorns with a team of just over 700 people

Among the fastest-growing tech companies in the UK

Profitable since 2017

Backed by top investors including Balderton Capital and Goldman Sachs

Loved by customers with the best reviews in the market (4.9 across 10,000s of reviews on Trustpilot)

So far, we’ve rebuilt the Big Three consumer finance products from scratch: loans, credit cards and car finance. We get money into our customers’ hands in minutes instead of days.

We’re growing fast, and there’s a lot more to do: we’re going after the two biggest Western markets (UK and US) where trillions worth of financial products are held by big banks with dated systems and painful processes.

Join us if you want to

Take ownership across a broad remit. You are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1

Work in small teams of exceptional people, who are relentlessly resourceful to solve problems and find smarter solutions than the status quo

Build the best technology in-house, using new data sources, machine learning and AI to make machines do the heavy lifting

About the role

We’re looking for a Lead Python Engineer to join our Data Team, where you’ll play a pivotal role in shaping the systems and data infrastructure that power our US products.

In this role you’ll balance hands-on engineering with team leadership — owning the technical direction of your squad, mentoring a small team of 1–2 engineers, and still getting deep into the code yourself. You’ll design and build robust data pipelines, APIs and services that drive real decisions across the business, all while keeping quality and scalability at the forefront.

You’ll be a key voice in architectural discussions, helping to define how we build and evolve our data platform as we scale into the US market. 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

Interest in leading or mentoring a small team of engineers, with the ability to balance hands-on delivery with team development

Deep, modern Python expertise; you write clean, idiomatic, well-tested code and hold others to the same standard

Some experience building and maintaining data pipelines, ETL processes, or data-intensive backend services

Solid understanding of FastAPI or a comparable modern Python web framework

Strong automated testing skills across unit, integration, and functional levels

Experience working with cloud infrastructure, ideally AWS, and comfortable with Docker and Kubernetes

Ability to drive technical decisions and communicate clearly with both engineers and non-technical stakeholders

Experience in a cross-functional or data-focused engineering environment is a strong plus

Familiarity with US financial products or regulated markets is a bonus, but not essential

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 30 mins

Final Interview
