Glückliche Gäste GmbH

Solutions Engineer

• You will build the integration domain of the Personal.manager (PM) as an engineer — not merely as a middleware configurator.
• REST endpoints for master data and lookups, and event- and webhook-based output for transactional data (absences, time entries, shift schedules, entitlements, payroll-relevant status changes).
• DB outbox pattern, worker logic, retry and dead-letter handling.
• Integration with EMQX as an internal event bus.
• Versioned payload contracts and an auditable integration history.
• Implement flows programmatically: custom scripts, adapter logic, and transformations. Keep PM ↔ SAP mappings testable and versioned.
• Build clear error channels and perform technical coordination with our customers' SAP teams.
