API & Integrations Engineer

Build reliable connections between Ordernised and the delivery, messaging and partner systems restaurants depend on.

The job

You will help external systems exchange information with Ordernised in a controlled, observable way. Integrations introduce different assumptions about identity, timing, errors and availability, so you will translate those differences into dependable workflows. You will work with partner documentation, sandbox environments and internal product teams to define what an integration should do, how failures are recovered and what support teams need to see when something goes wrong.

What you would be doing

• Develop API clients, webhook endpoints and adapters for external services.
• Define data mappings and validation rules between partner and Ordernised models.
• Implement bounded retries, idempotency, rate-limit handling and failure queues where appropriate.
• Manage integration credentials through approved secure configuration mechanisms.
• Create contract tests and sandbox scenarios for common provider failure modes.
• Publish clear integration documentation and support-facing troubleshooting guidance.
• Monitor provider changes and coordinate updates without unnecessary disruption to restaurants.

What we are looking for

• Experience developing production APIs or third-party integrations.
• Understanding of HTTP, authentication patterns, webhooks and asynchronous processing.
• Ability to reason about retries, duplicate messages and partial failure.
• Practical database and automated-testing skills.
• Confidence reading external documentation and communicating integration constraints.

Useful, but not essential

• Experience with delivery, dispatch, messaging or commerce APIs.
• Familiarity with iCabbi, Twilio or comparable platforms.
• Experience supporting API consumers or working directly with technical partners.

Tools you might use

• TypeScript
• Node.js
• REST APIs
• Webhooks
• PostgreSQL
• Contract testing
