API and Legacy Systems Integration Engineer

You connect a person's agent to the services that already run their life and business: the bank, the calendar, the practice-management system, the thing the accountant insists on. Making an ordinary workflow dependable across interfaces that were never designed for this is the work, and it is mostly about failure handling rather than the first successful call. Depth matters far more here than familiarity with every format.

Apply for this roleAll roles

Open for applications. Starts at: Pilot expansion.

We are taking applications for this role now and building the pipeline for it. The stage above is when the work itself is expected to begin, which is something you deserve to know before you apply rather than after. It is context, not a gate.
