Senior Engineer: Pioneering the Next Generation of Financial Technology

Our client is a high-growth tech firm on a mission to fundamentally reinvent global banking. 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The banking world is currently held back by "legacy debt"—outdated, monolithic systems that are slow and fragile.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: Deep, production-level experience with Go is essential.
• 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 Depth: You have an extensive understanding of concurrent processing, asynchronous messaging (Kafka/RabbitMQ), and the challenges of operating across multi-region database setups.
• 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.
• Engineering Excellence: A strong advocate for clean code, observability, and building for long-term scalability.

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