This is an 11-week summer internship within a global FinTech organisation operating one of the world’s largest digital payments networks.

You’ll gain hands-on experience working on high-impact systems that power secure, real-time transactions at global scale. As part of a collaborative engineering team, you’ll contribute to the development of next-generation payment technologies while building your technical and commercial skillset.

High-performing interns may be considered for future graduate opportunities.

What you’ll be doing

• Supporting the development and delivery of software across the full engineering lifecycle (design, build, test, deployment)
• Contributing to scalable, secure systems used by millions of users globally
• Working within Agile teams to deliver features and improvements in iterative cycles
• Developing tools and solutions to improve processes and system performance
• Gaining exposure to modern technologies, frameworks and infrastructure
• Collaborating with engineers and stakeholders to solve technical challenges

Technologies you may work with

• Programming languages such as Java, Go or similar
• REST APIs and microservices architecture
• SQL and NoSQL databases
• Docker and containerisation tools
• Version control systems (e.g. Git/Bitbucket)
• Unix/Linux environments and scripting

What you’ll gain

• Real-world experience working on large-scale, high-performance systems
• Exposure to modern engineering practices including Agile, CI/CD and DevOps principles
• Mentorship from experienced engineers and access to structured learning
• Opportunity to build a strong technical foundation within a global FinTech environment
• Potential pathway into a graduate software engineering role

Key criteria

• Currently studying a bachelor’s or master’s degree in Computer Science or a related STEM discipline
• Due to graduate in 2027
• Experience with at least one object-oriented programming language (e.g. Java, Python, C++)
• Strong understanding of core software engineering principles (data structures, algorithms, problem-solving)
• Passion for technology, with evidence of coding beyond academic work (e.g. personal projects, GitHub, hackathons)
• Strong analytical thinking and attention to detail
• Collaborative mindset with the ability to work effectively in team environments
• Positive attitude, with a willingness to learn and adapt quickly

Desirable (not essential)

• Exposure to distributed systems, APIs or microservices
• Familiarity with cloud technologies or containerisation tools
