Job Description

Senior Integration Developer - Liverpool (Hybrid Working)

We are looking for a Senior Integration Developer to design, build, and lead the delivery of critical integrations that power our connected platform. You’ll play a central role in ensuring reliable, secure, and scalable data flows between internal systems, finance platforms, customer solutions, and third-party applications.

This role combines hands-on development with architecture input, stakeholder collaboration, and technical mentoring. If you’re passionate about building well-engineered, high-impact integration platforms and solutions that support real-world business outcomes, then this role is for you.

Key Responsibilities

• Design, develop, and maintain secure, high-performance integrations between enterprise systems and external platforms using APIs, file exchanges systems and messaging.
• Contribute to the development of a scalable Integration Platform and the best practice implementation of integrations.
• Collaborate with customers, finance, operations, and technology teams to streamline processes such as invoicing, reconciliation, and reporting through standardised integration patterns and data contracts.
• Shape our product’s integration architecture—ensuring reusability, scalability, and future-readiness across our growing ecosystem.
• Build custom connectors, scripts, and workflows where required (using technologies such as C#).
• Ensure all integrations adhere to security best practices, data protection regulations, and internal governance standards.
• Track integrations and performance though telemetry, instrumentation and observability to ensure a clear picture of which customers are using which patterns and endpoints/exchanges.
• Ensure DevOps practices for integration—supporting Git source control, CI/CD pipelines, testing automation, and deployment standards.
• Document technical designs, workflows, data mappings, and dependencies in a clear, maintainable format.
• Mentor junior developers and provide technical leadership across integration projects.
• Participate in Agile delivery cycles—collaborating closely with cross-functional squads to plan, deliver, and review work
  
  

Skills & Experience

• 5+ years of experience in system integration, backend development, or software engineering.
• Deep understanding of integration patterns: APIs, webhooks, messaging, file sharing, data mapping, data transformation and ETL.
• Strong development background in C# or a similar language, with experience applying software engineering principles (e.g. SOLID, clean code).
• Experience with Azure Integration Platform as a Service technology (e.g. Azure Functions, Event Grids, Event Hubs, Service Bus, Azure Data Factory, Logic Apps, APIs Management, etc).
• Proven experience with finance systems and data-sensitive processes.
• Knowledge of CI/CD tools and DevOps practices for automated deployment.
• Strong documentation skills and ability to communicate effectively with both technical and non-technical audiences.
