About Abound
We’re redefining consumer lending in the UK, and beyond. Using advanced AI and Open Banking data, we make fair, affordable personal finance available to more people. While traditional lenders rely almost entirely on credit scores, we look at the full financial picture - how much you spend, and what you can afford to repay to build a deeper, more accurate understanding of each customer's unique financial situation.
And we've shown it works at scale. We’ve issued over £1.3bn in loans directly to customers while delivering market-leading credit performance - for every 10 defaults the industry expects, we see only 3. We also reached profitability just 2.5 years after launch.
Backed by £2bn+ of funding from top-tier investors including Citi, GSR Ventures, and Deutsche Bank, we’re recognised as one of Europe’s fastest-growing fintechs (Sifted, CNBC). Now, we’re expanding into new markets and product lines - and we’re looking for ambitious people who want to learn fast, take ownership, and grow with us.
About the Role
We're looking for a hands-on Lead Software Engineer to lead technology delivery for Abound Spain. This role will be responsible for adapting, deploying and operating Abound’s lending platform in Spain, ensuring it meets local business, operational and regulatory requirements while remaining aligned with our global technology strategy.
This role combines hands-on software engineering, solution architecture, technical leadership and team management, reporting to the Spain Director and to the Chief Product Officer. While remaining actively involved in software development, you will act as the technology owner for Spain, ensuring Abound’s global platform is successfully localised, integrated and operated within the Spanish market.
You will work closely with Product Managers, Engineering, Risk, Operations, Compliance and external technology partners to translate business requirements into scalable technical solutions. You will help shape the local technology roadmap, ensuring that Spain benefits from the strength of Abound’s existing platform while adapting it to the needs of the local market.
We value engineers who enjoy solving complex problems, take ownership beyond writing code, and are equally comfortable discussing architecture, integrations, operational resilience and software delivery. This is an opportunity to play a key role in launching and scaling Abound’s business in Spain while remaining close to the technology.
At Abound, you'll be part of a culture that values autonomy, curiosity and continuous improvement. You'll work with a modern Python-based technology stack, gain deep exposure to consumer lending and fintech, and can build a scalable technology operation from an established global platform.
