Integraal Data Services

As a partner to prestigious companies in French-speaking Switzerland, we are looking for a passionate and experienced Business Solutions Architect to join our dynamic team.

Reporting to the performance and project steering management (PPP), the Business Solutions Architect (ASM) sector plays a central role within the OCSIN in the design, maintenance, and evolution of the business solutions that support the processes and strategies of the Geneva cantonal administration. It intervenes in the design of OCSIN projects and programs, in collaboration with other architects and technical teams, in order to guarantee solutions consistent with architecture strategies and meeting business requirements.

The sector thus accompanies business units and project teams in translating needs into solution architectures, taking into account business processes, data, integrations between systems, as well as quality, security, performance, and sustainability requirements. It also contributes to the evolution and modernization of solutions, to the definition of reusable standards and patterns, and to the anticipation of technological obsolescence.

In this context, the sector wishes to strengthen itself with an ICT (information and communication systems) architect, intervening transversally across different business domains, programs, and projects. Through their expertise in business solutions architecture and their transversal positioning, the architect contributes to ensuring the consistency of solutions with existing systems, OCSIN orientations, and the evolution trajectories of the information system. They thus participate in the design of sustainable, scalable, and integrated solutions, while accompanying business units and teams in their implementation and evolution.
