Role summary
We are looking for a Senior Mendix Developer to act as Technical Lead for a large, multi-phase enterprise Mendix programme, building the most complex processes and integrations and leading a hybrid onsite/offsite team of Mendix, mobile, integration and DevOps engineers.
Key responsibilities
Lead the day-to-day technical build and act as the technical point of contact for the development, mobile, integration and DevOps team.
Take over an existing Mendix application built by another team and extend it rather than rebuild it.

Guide the build of shared components: request handling, configurable rules, notifications, document generation, schedulers, reports and KPI dashboards.
Guide the Mendix native mobile build (iOS and Android), including offline drafts, secure storage, biometric login, push notifications and in-app payments.
Lead the Mendix side of all integrations with the Integration Developer: REST/SOAP contracts, error handling, retries, idempotency, exception queues and reconciliation.
Integrate with document management, digital identity and e-signature, payment gateway, finance/ERP, banking, CRM and government systems through the ESB.
Work with the DevOps Engineer on CI/CD for Mendix web and native mobile builds, environment promotion and releases in waves.
Set development standards, run code reviews, estimate work and track progress through each wave and tollgate.
Support SIT, performance and security testing, UAT, go-live and hypercare.
Mentor developers onsite and offsite, and hand over documentation to the client's support team.

API authentication (OAuth 2.0, OIDC, API keys, certificates) and integration through an ESB / middleware layer.
