What does the Membership Development & Engagement Officer do?
The position sits within ISS’s Network Development & Engagement Unit and is centered on developing and strengthening the organisation’s international membership network.
Rather than being described as a general administrative position, the vacancy is specifically connected to how ISS engages with existing members, expands its network and brings new members into the organisation. The officer will also coordinate activities designed to build capacity across the network.
The main areas of focus are:
- Member engagement: helping strengthen relationships and engagement across the ISS global network.
- Network expansion: contributing to the development and growth of the organisation’s membership network.
- New-member integration: supporting the integration of new members into the ISS network.
- Capacity building: coordinating activities intended to strengthen capabilities within the network.
The officer will report to both the Membership Development & Engagement Head and the Secretary General, placing the role within the organisation’s Network Development & Engagement structure.
Who is this ISS position aimed at?
The source lists 3–4 years of experience for the opportunity and categorises it under Program/Project Management.
That makes the vacancy particularly relevant to professionals whose background aligns with programme or project-related work and who are interested in membership development, network engagement, organisational growth and capacity-building activities.
The supplied vacancy information does not provide additional qualification, nationality, residency, visa, salary or benefits details, so applicants should rely on the full employer job description for any requirements not stated in the vacancy notice.

Why the network-development focus matters
The distinctive feature of this vacancy is its emphasis on the ISS global network. The successful applicant will be working around the relationships and structures that connect ISS members, rather than focusing solely on an individual project.
The four areas identified in the vacancy—member engagement, network expansion, new-member integration and capacity-building coordination—also indicate the breadth of the position. Applicants should therefore pay close attention to how their own experience relates to these areas when preparing their CV and motivation letter.
Because the motivation letter is limited to one page, candidates should keep it focused on the relevance of their experience to the Membership Development & Engagement Officer position rather than using it to repeat their entire CV.
Application deadline
The closing date for the International Social Service Membership Development & Engagement Officer vacancy is 27 September 2026. The position is based in Switzerland, and the vacancy was posted on 4 September 2026.
Candidates interested in the role should make sure their application follows the specified document length, language, format and email-subject requirements before submitting it.
