The Opportunity

On behalf of a global powerhouse in FinTech Infrastructure, we are seeking a Senior Software Engineer. Our client operates one of the largest financial networks, serving as the digital backbone for thousands of global financial institutions. This is a senior-tier appointment for an engineer who excels at building resilient, high-concurrency systems and wants to lead the digitalization of global financial markets.

The Technical Stack

You will be working within a modern, engineering-first culture. The core stack includes:

The Engine: Expert-level C# and .NET Core mastery.
Architecture: Deep understanding of SOA (Service Oriented Architecture) and complex Object-Oriented design patterns.
System Dynamics: Specialized knowledge of concurrency, asynchrony, and parallelism—essential for real-time transactional processing.
Data & Web: High proficiency in SQL Server, Web API design, and modern front-end fundamentals (HTML/CSS/JS).
Reliability: A strict practitioner of TDD (Test Driven Development) and robust CI/CD processes.

Desired Innovations

Our client is actively modernizing. Exposure to the following is highly valued:

Cloud & Orchestration: Azure ecosystems, Docker, and Kubernetes (AKS).
Messaging Patterns: Enterprise systems like Azure Service Bus or NServiceBus.
Next-Gen Tech: Experience with Blockchain development or Cryptographic concepts is a significant plus.
Modern UI: TypeScript and Angular for responsive, data-heavy interfaces.

Your Impact

Technical Leadership: You will participate in defining the technology and process strategy, occasionally leading high-level innovation or software design initiatives.
Full-Lifecycle Ownership: Design, document, and communicate system solutions that balance high performance with security and cost-effectiveness.
Collaboration & Mentorship: Act as a "Technical Enabler," bridging the gap between deep engineering and business-led requirements while mentoring junior talent.
Innovation: Drive the modernization of global financial infrastructure, replacing frictional legacy processes with fast, efficient, and scalable digital services.

Who You Are

FinTech Professional: You have a deep commercial background in Financial Services, Payments, or Transactional Systems. You understand the stakes of high-volume, regulated data.
Team-Centric: You thrive in an Agile environment where team dynamics and peer reviews are taken seriously.
Strategic Thinker: You can contextualize your technical work for non-technical stakeholders and have a passion for "big picture" system evolution.

Package & Culture

Salary: £90,000-£100,000 per annum + Performance-related Bonus.
Flexibility: A balanced Hybrid model out of a state-of-the-art Central London office.
Benefits: Industry-leading pension, private healthcare, and a culture that prioritizes professional growth.
