Job description

We are partnering with a highly successful, international Wealth Management firm. The business has a complex, dual-era technology ecosystem and is currently facing an urgent timeline to deliver critical system integration and backend architecture projects.

Historically, their team has managed a wide tech stack. They are now looking for an experienced, Full Stack or Backend Specialist to join the team and focus on accelerating their backend integration and core systems delivery.

Key Responsibilities:

• This role sits largely on the backend, focusing heavily on executing a business-critical integration programme to meet strict upcoming deadlines.
• Own the design, maintenance, and execution of robust data flows and integration pipelines, securely connecting core internal platforms and external third-party systems.
• Build and consume production-grade, highly secure RESTful APIs and modern backend Web Services to allow seamless cross-application communication.
• Handle complex database engineering tasks within a high-throughput environment, writing performance-tuned SQL Server (T-SQL) queries, stored procedures, and managing data indexing.
• Utilise robust software engineering principles—including automated CI/CD pipelines via Azure DevOps—to ensure all backend systems remain resilient, fully auditable, and secure by design.

Your Background:

• 5+ years of full stack or backend engineering experience is highly preferred.
• Prior experience within Financial Services (Wealth Management, Asset Management, or Banking) is strongly preferred.
• Exceptional, hands-on coding capability in C# and the .NET framework, combined with advanced relational database proficiency in SQL Server (T-SQL).
• Strong familiarity with building scalable APIs and working with event-driven data architectures or messaging queues (e.g., RabbitMQ, Kafka).
• You must be highly delivery-oriented, comfortable navigating tight sprint timelines, and able to work independently to unblock complex backend issues.
