Senior Technical Integration Engineer

Location: Geneva · Contract: Permanent · Assignment: long term · Rate: 100% · Start: January 2027

For one of our clients based in Geneva, we are looking for an experienced Senior Technical Integration Engineer.

Context

Within the infrastructure management department, responsible for the operation of information systems, the Integration service orchestrates the transition from development to testing and then to production, and automates application operations. It acts as an interface between application providers, infrastructure teams and services.

The service operates within a DevSecOps approach. In connection with development projects and infrastructure teams, it deploys high-service-level systems into production, aiming to maintain the service levels of managed assets while integrating their growth and risks related to obsolescence. It contributes to the 24/7 operational maintenance of managed systems, including critical systems with very high availability.

The service's mission covers three areas:

• Technical integration and deployment of application solutions on IT environments

• Design and implementation of operational assets for managed systems and applications

• System operation supporting the second-level operations team

The service is organised into two divisions:

• A specialised integration division, which evolves integration methods so that custom solutions become standard or new standards, capitalising on acquired experience

• An industrialised integration division, which handles a large volume of integration projects with optimised workload and deadlines

As a technical integration engineer, you create integration and operational assets and are responsible for the operability of applications and the quality of production releases. You support service managers in implementing integration and operational processes and best practices. The role combines technical expertise with the ability to synthesise and deliver solutions in a service-oriented approach.
