Business Solutions Architect - Geneva

About the job

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

Attached to the performance and project management department (PPP), the Business Solutions Architect (BSA) sector plays a central role within OCSIN in the design, maintenance and evolution of business solutions that support the processes and strategies of the Geneva cantonal administration. It is involved in the design of OCSIN projects and programmes, in collaboration with other architects and technical teams, to ensure solutions are consistent with architectural strategies and meet business requirements.

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

In this context, the sector wishes to strengthen itself with a TIC architect (information and communication systems), working transversally across different business domains, programmes and projects. Through their expertise in business solution architecture and transversal positioning, the architect helps ensure the coherence of solutions with existing systems, OCSIN orientations and information system evolution trajectories. They thus participate in the design of sustainable, scalable and integrated solutions, while supporting business units and teams in their implementation and evolution.
