Lendable · London
Lendable is a fast‑growing fintech firm that builds credit, loan and car‑finance products for consumers in the UK and US. The company focuses on replacing legacy banking systems with modern, data‑driven technology, using machine learning and AI to streamline operations. The Senior Python Engineer will join the Central Operations team, which creates internal web applications and automation tools that support the broader Ops function, including fraud prevention and customer support. Day‑to‑day work involves designing and implementing full‑stack features using FastAPI on the backend and React/Next.js on the frontend, integrating AI‑based solutions such as LLM‑driven call summarisation, and ensuring code quality through testing and clean‑code practices. The role requires ownership of shipped features that are used daily by ops agents, collaboration with product, data science and analytics teams, and continual improvement of the technical direction. Ideal candidates have eight or more years of software engineering experience, strong Python expertise, familiarity with modern JavaScript frameworks, solid engineering fundamentals, and a collaborative mindset, with optional experience in DDD, event‑driven architectures or AWS.
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 most exciting unicorns with a team of over 800 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: 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: Lendies are relentlessly resourceful. We challenge the status quo to solve problems and find smarter solutions Build the best technology in-house : we use new data sources, machine learning and AI to make machines do the heavy lifting We’re looking for a full-stack Python engineer to join our Central Operations team. Central Ops sits across our core products (Cards, Loans and Motor), focusing on shared operational challenges and opportunities. We build a mix of internally facing web applications and robust automations to help our Operations teams deliver great outcomes for customers, efficiently and at scale. It’s a broad space: Operations makes up roughly half of our employee headcount and covers everything from day-to-day customer support up to complex areas like Fraud and Fincrime prevention. As our customer base grows rapidly, our role is to help ops keep pace without relying solely on headcount growth. We make intelligent, pragmatic use of AI where it adds real value, working closely with Product, Data Science and Analytics to deploy solutions that genuinely support our ops agents. You’ll have real ownership from an engineering perspective, shipping features that are used daily by Ops teams. It’s an evolving space at Lendable, and what you build will help shape both our tools and our technical direction. Some examples of things we’ve built recently: Rebuilt our Ops QA admin system from the ground up, replacing an off-the-shelf tool with something tailored to our needs Deployed a pipeline to summarise customer calls into concise notes using LLMs, automatically surfaced in ops admin panels — removing the need for manual note-writing More than doubled the number of complaints processed by agents through a combination of targeted AI automation and improved UX What we’re looking for We’d consider the following essential to the role: You have 8+ years of professional experience as a software engineer Solid experience with Python in a web application context. You have some experience with web frameworks like FastAPI, Django or Flask. We use FastAPI. Experience with Javascript/Typescript and a modern JS framework such as React, Angular or Vue.js.
