Engineer systems that power real-world commerce.

Our client is building the next generation of capabilities that power a fast-growing, merchant-focused ecosystem. Their mandate is clear: deliver value radically, responsibly, and consistently.

They believe focused, empowered teams can achieve exceptional outcomes. They value results over activity, curiosity over complacency, and practical execution over unnecessary process. If you’re driven by impact and enjoy solving meaningful technical challenges, this could be an excellent fit.

The Role

As a Software Engineer, you will design and develop backend services, APIs, and portal systems that operate within high-availability payment processing platforms.

Working within a dynamic development centre, you’ll engage with modern frameworks, tools, and engineering practices including:

• Behaviour-Driven Development (BDD)
• AI-assisted development tools

From requirements analysis through to production release, the team owns the full lifecycle. You may work independently on focused initiatives or as part of a larger squad, always empowered to concentrate on solving technical problems rather than navigating inefficient processes.

Key Responsibilities

• Translate merchant and partner needs into high-quality, scalable backend solutions
• Design and build robust Java-based systems and RESTful APIs
• Improve development processes through automation, simplification, and applied engineering experience
• Collaborate to ensure technically sound, observable, and testable deliverables
• Contribute to estimation, planning, and proactive risk management
• Support deployment to test and production environments
• Take ownership beyond assigned tasks, adjusting priorities where required
• Demonstrate professionalism, flexibility, and strong team collaboration

What They’re Looking For

• 3–5 years’ experience in a Software Engineering role
• Degree in Computer Science or related discipline
• Proficiency in Spring Boot or J2EE
• Solid understanding of Spring Core (IoC and Dependency Injection)
• Strong experience with relational databases, schema design, complex queries, and performance optimisation
• Experience designing and implementing scalable RESTful APIs
• Hands‑on experience building high‑availability, high‑concurrency systems at scale
• Strong understanding of Design Patterns, Refactoring, and Object‑Oriented Design principles
• Experience with Git, CI/CD pipelines, and modern development methodologies
• Familiarity with AI-driven development tools (e.g., Windsurf, Claude Code, or similar)
• Self‑starter mindset, comfortable operating independently or within a team
• Strong analytical, problem‑solving, and communication skills
• Detail‑oriented, proactive, and able to work effectively under pressure

What You Can Expect

• An empowered engineering culture
• Clear ownership and accountability
• A high‑performance yet pragmatic working environment
• Continuous learning and professional growth
• The opportunity to build resilient systems that operate at real scale

If you’re looking to engineer scalable, high‑availability systems within a culture that values autonomy and technical excellence, this is a strong opportunity to make meaningful impact.
