Integration Developer

Location:

London - 4 days in the office, 1 day from home

Salary: £50,000 - £65,000

The Opportunity

We're working with an established consumer-facing organisation that's investing significantly in the modernisation of its technology landscape.

With a new eCommerce platform, a new third-party logistics partner and an ERP upgrade all being delivered concurrently, the business is now building an internal integration capability to take long-term ownership of how its critical systems connect.

This is not a role where you will simply maintain what already exists.

You will help build the integration layer that keeps orders moving, stock accurate and deliveries going out on time.

The Role
  • eCommerce and order management platforms
  • Warehouse management and 3PL systems
  • ERP platform
  • Downstream business applications

    You will work closely with a newly appointed Technical Lead, alongside QA and Delivery Planning, with genuine ownership of the integrations you develop.
Key Responsibilities
  • Build and maintain APIs, data flows and middleware integrations
  • Develop and own solutions using Azure Integration Services
  • Support the new warehouse go-live and integration hypercare
  • Monitor live integrations, investigate incidents and resolve failures
  • Build the eCommerce and OMS integration layer
  • Develop ERP integration components from established technical designs
  • Test, deploy and monitor integration pipelines
  • Produce clear runbooks, data flow diagrams and error-handling documentation
  • Work closely with internal teams and external delivery partners
About You

You will have:

  • Commercial experience building integrations in a production environment
  • Hands-on experience with Azure Integration Services, Logic Apps, Service Bus or a comparable integration platform
  • Strong experience working with REST APIs, JSON and XML
  • Knowledge of OAuth 2.0, API keys and common authentication patterns
  • Experience building event-driven flows or middleware pipelines
  • A strong debugging mindset and the ability to resolve integration failures properly
  • The confidence to work independently and take ownership of delivery
  • Experience integrating ERP, eCommerce, OMS, warehouse or logistics platforms would be highly advantageous.
