Senior Integration Engineer – SAP, Enterprise Interfaces

This is a fully remote position, open to applicants in Germany.

📋 Description

• As an engineer, you will be responsible for developing the integration domain of the Personal.manager (PM) rather than just configuring middleware.

• Create REST endpoints for master data and lookups, along with event- and webhook-based outputs for transactional data such as absences, time entries, shift schedules, entitlements, and payroll-relevant status changes.

• Implement the DB outbox pattern, along with worker logic, retry mechanisms, and dead-letter handling.

• Integrate with EMQX to serve as an internal event bus.

• Ensure versioned payload contracts and maintain an auditable integration history.

• Develop flows programmatically by using custom scripts, adapter logic, and transformations, ensuring that PM ↔ SAP mappings are both testable and versioned.

• Establish clear error communication channels and coordinate technical aspects with our clients’ SAP teams.

⛳️ Requirements

• You engage in daily coding activities.

• You have a strong background in building REST APIs and event-driven integrations using Node.js/TypeScript or a similar technology stack.

• Familiarity with PostgreSQL is essential.

• You possess practical knowledge of the components that contribute to robust integrations, including the outbox pattern, idempotency, retry strategies, dead-letter queues, webhooks, and MQTT/AMQP brokers like EMQX, RabbitMQ, and Kafka, as well as structured logging, correlation IDs, and versioned contracts.

• You view interfaces as systems governed by clear contracts.

• For you, an integration is not considered “complete” until it can operate unattended overnight, recover from errors, and make events transparent.

• Experience with SAP Integration Suite (Cloud Integration / CPI), especially its programmatic extension points such as Groovy scripting, custom adapters, and custom flow logic is highly valued.

• Background in regulated customer environments, including DMZ gateways and audit-compliant logging, is preferred.

• Knowledge of SaaS platform architectures, API design, and event-driven architectures is beneficial.

🏝️ Benefits

• Enjoy the flexibility of working 100% remote, in a hybrid model, or on-site in St. Wendel.

• Receive a competitive salary that reflects your experience and responsibilities.

• Benefit from 30 days of vacation.

• Work in a modern office equipped with a shower, washing machine, and an espresso machine.
