Our client is a high-growth tech firm redefining global banking fundamentally. They are building the world’s first autonomous, composable platform capable of powering Tier-1 financial institutions at a massive scale.

The banking world is currently held back by "legacy debt"—outdated, monolithic systems that are slow and fragile. This team is replacing that friction with an elegant, AI-centric, and highly performant core that redefines how the largest banks worldwide manage their operations. To lead this shift, they are looking for a Senior Engineer to join their core team in London.

📍 Location: Central London (Fully on-site)

📌 Salary: Up to £150,000 + Benefits

Why This Role? This isn't just another fintech role; this is an opportunity for an engineer who thrives on tackling "hard" problems in complex distributed systems. You won't just be maintaining a product; you will be writing mission-critical code that introduces simplicity, openness, and modular design into a massive, heavily regulated sector.

You will have the rare chance to build the future of financial infrastructure from the ground up, working alongside some of the brightest minds in the industry.

🚩 What They Are Looking For The ideal candidate is a proactive, resourceful, and technically excellent system builder who enjoys the "full-stack" of backend engineering—from the kernel to the cloud.

• Golang Expertise
• Technological Flexibility: You possess a natural ability to transition seamlessly between high-level architectural design, low-level coding, rigorous testing, and operational (DevOps) tasks.
• Distributed Systems Deptg
• High Autonomy: You thrive with independence. You are a "problem-owner" who proactively solves complex bottlenecks and skillfully manages your own prioritization.
• Modern AI Integration: You have an active interest or experience in leveraging advanced AI tools to enhance development workflows and automate platform operations.

If you want to move away from mundane features and start building the backbone of global finance, we want to hear from you.
