Senior Integration Developer / API Developer

Senior Integration Developer (API Developer) | Contract (6month) | Auckland
We’re looking for an experienced Senior Integration Developer / API Developer to join our client on a hands-on integration project connecting Microsoft Dynamics 365 CE with an external platform.

In this role you’ll be responsible for developing and supporting system-to-system integrations, working across REST APIs, data transformation and Dynamics CE. The integration will operate in both directions: extracting and transforming data from Dynamics CE for external APIs, and bringing status and completion data back into CE.

This is a practical development role suited to someone who is comfortable getting into the detail, troubleshooting integrations and delivering reliable API-based solutions.

You’ll bring:

• Strong C# / .NET development experience
• Proven experience designing, developing and consuming REST APIs
• Strong understanding of JSON payloads, data mapping and transformation
• Experience with authentication including OAuth2, API Keys and JWT
• Strong API integration troubleshooting and debugging capability
• Experience with asynchronous processing, logging and error handling
• Previous experience delivering system-to-system integrations
• Ideally, hands-on experience with Microsoft Dynamics 365 CE and Dataverse

Bonus: Experience developing Dynamics plugins and custom workflows, and exposure to Power Platform and Azure integration services. Exposure to middleware platforms such as MuleSoft, Boomi, OIC or Informatica would also be advantageous.

If you are comfortable working independently, understanding existing integration logic and getting up to speed quickly in an established environment, this contract role might just be for you! Apply Today and Luisa Larios (Luisa@momentum.co.nz) will be in touch. 

**Please note only applicants currently based in New Zealand with the appropriate work rights (a valid visa) will be considered**
