Company Description
We're Checkout.com - you might not know our name, but companies like eBay, ASOS, Klarna, Uber Eats, and Sony do. That moment when you check out online? We make it happen.
Checkout.com is where the world checks out. Our global network powers billions of transactions every year, making money move without making a fuss. We spent years perfecting a service most people will never notice. Because when digital payments just work, businesses grow, customers stay, and no one stops to think about why.
With 19 offices spanning six continents, we feel at home everywhere - but London is our HQ. Wherever our people work their magic, they're fast-moving, performance-obsessed, and driven by being better every day. Ideal. Because a role here isn't just another job; it's a career-defining opportunity to build the future of fintech.
Job Description
Global payments are complex and ever-evolving. At Checkout our software engineers develop the next-generation payments technologies that enable our Merchants to boost their acceptance rates, cut processing costs, fight fraud, and create cutting edge technology that enables extraordinary customer experiences.
We're looking for engineers who bring fresh ideas, have a curious nature and are passionate about working in an Engineering environment which focuses on building products to achieve the company's strategic goals. You'll get to work with teams from across Checkout.com's portfolio of products and services who all have a real customer first philosophy.
As a software engineer, you will work on a specific project critical to Checkout's needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display exceptional leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward. Across the business we primarily use C# .Net Core, hosted on AWS with event-driven microservices, but we're happy to up-skill engineers from certain backgrounds like Java to adapt to our stack. With your technical expertise you will lead project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions.
About you:
Bachelor's or Master's degree in Computer Science, Engineering, or related field.
Proficiency in Python, with good knowledge of either .NET C#, Java, or Go, with a strong understanding of software development principles in either a backend or full stack environment.
Great communication skills and ability to interact effectively with a wide range of stakeholders.
Experience working in agile environments and delivering high-quality code within tight deadlines.
Excellent problem-solving skills and the ability to work independently as well as part of a team.
Payments or financial knowledge is a plus, but not a necessity.
How you'll make an impact
Be part of, and collaborate with, cross-functional teams including product management, across a large engineering community.
Define and design loosely coupled, scalable systems in a wider microservices using industry best practices.
Stay up-to-date, use, and spread knowledge of the latest technologies used by Checkout.
Write clean, maintainable, extendable and testable code on some of Checkout's most impactful systems.
Build, own and operate your systems to the highest levels of resilience and service.
Mentor junior team members and assist in their technical development .
Bring all of you to work
We create the conditions for high performers to thrive - through real ownership, fewer blockers, and work that makes a difference from day one.
Here, you'll move fast, take on meaningful challenges, and be recognized for the impact you deliver. It's a place where ambition gets met with opportunity - and where your growth is in your hands.
We work as one team, and we back each other to succeed. So whatever your background or identity, if you're ready to grow and make a difference, you'll be right at home here.
It's important we set you up for success and make our process as accessible as possible. So let us know in your application, or tell your recruiter directly, if you need anything to make your experience or working environment more comfortable.
