About the Role

The Senior .NET Integration Developer is a 100% hands-on engineering role responsible for building and connecting services between a newly introduced third-party vendor platform and several internal enterprise systems. The role is focused on .NET development and API-driven integrations, including building backend services and integration components.

This is a senior individual contributor role – the primary deliverable is working, production-quality code. The role works to an existing technical design and architectural direction, and contributes hands-on across the full integration stack rather than leading a team.

Key Objectives of the Role

• Build and ship end-to-end integrations between third-party vendor systems and internal platforms

• Provide hands-on .NET development and integration engineering across the squad

• Implement scalable, secure patterns for API-based connectivity via the organisation's API gateway and internal services

• Ensure solutions connect systems via APIs rather than building workflows inside vendor middleware tools

Key Responsibilities

Hands-On Engineering

• Spend the majority of time writing, testing, debugging, and shipping production code

• Implement integration services and .NET application components in line with the agreed technical design and architecture

• Follow established coding standards and engineering practices; actively participate in code reviews and contribute to quality, security, and maintainability

• Work through ambiguity typical of greenfield delivery and new system onboarding — pick up unfamiliar systems quickly and start producing working code

Integration & Backend Engineering

• Build backend integration services connecting third-party platforms and internal systems via APIs and the API gateway

• Integrate with third-party APIs directly where available, and via vendor middleware where required

• Deliver end-to-end system plumbing across vendor platforms, API gateway, internal services, and enterprise systems (e.g. Business Central)

Collaboration & Delivery

• Work closely with internal stakeholders, architects, and vendor teams to translate architecture and designs into working solutions

• Identify delivery risks early (dependencies, API limitations, environment readiness) and propose mitigations

• Keep Jira and reporting accurate at all times so squad delivery status is always clear

Essential Skills & Experience

• Proven experience as a Senior Engineer / Senior .NET Developer / Senior Integration Developer delivering enterprise-grade solutions

• Strong .NET development experience (mandatory)

• Strong backend development experience building APIs and services

• Extensive hands-on experience with system-to-system integrations and third-party platform integration

• Experience delivering greenfield implementations or new capability builds

Desirable Skills & Experience

• Familiarity with integration middleware platforms (e.g. Workato or similar)

• Exposure to ERP or enterprise platforms such as Business Central

• Experience working with API gateways and API security patterns
