The Role

We are looking for a Full Stack Software Engineer to join our growing development team. The ideal candidate will be confident working across both back-end and front-end technologies, particularly within a modern Azure-based environment.

You'll design, build, and maintain applications that drive client-facing products and internal systems - ensuring scalability, performance, and resilience. Working closely with product managers, designers and DevOps engineer, you will play a key role in shaping the architecture, automating deployments and supporting smooth integrations across the platform.

Key Responsibilities

• Design, develop and maintain full stack applications using modern frameworks and technologies.
• Build efficient and reusable components for both front-end and back-end systems.
• Work with Azure cloud infrastructure to deploy, monitor and maintain applications.
• Collaborate with cross-functional teams to ensure seamless integrations and data flow between systems.
• Maintain clean, well-documented and testable code across all layers.
• Participate in design discussions, code reviews and technical decision-making.
• Support continuous improvement by identifying and implementing enhancements to processes and tooling.

• Azure cloud services (App Services, Azure DevOps, Functions, Service Bus).
• CI/CD automation, pipelines, and source control (Azure DevOps, GitHub, GitLab).
• RESTful API design and integration; experience with microservices architecture.
• Relational databases experience, primarily SQL Server, preferably via Entity Framework but can consider other ORM experience as relevant.
• Containerisation using Docker and orchestration with Kubernetes (a nice to have but not essential).
• Familiarity with monitoring and observability tools such as Grafana, Prometheus, or App Insights.
• Experience in agile delivery environments with testing such as XUnit with NSubstitute in particular.
• Exposure to Infrastructure-as-Code (Terraform, ARM templates) desirable.

What We're Looking For

• 7–12 years of hands-on development experience covering both front-end and back-end technologies.
• Demonstrable experience delivering scalable applications in cloud environments.
• Solid understanding of CI/CD and DevOps principles.
• Strong problem-solving skills with attention to detail and maintainability.
• Comfortable working independently and collaboratively within a fast-paced, agile environment.
• Excellent communication skills, with the ability to explain technical concepts clearly.
• STEM background (Computer Science, Engineering, or similar) is desirable.
• Experience within fintech, banking or wealth management sectors is advantageous.

What We Offer

• A chance to work on real-world technology used by investment professionals.
• The opportunity to design and implement solutions that directly improve client experience.
• A collaborative team environment that values independence but where help is always available when needed.
• Flexible working with a focus on outcomes and autonomy.
• Competitive compensation and benefits.
