This position is located within the Operational Planning Service (OPS) under the Division for Special Activities (DSA) of the Department of Operational Support (DOS) and will be based in New York. DOS was established to provide operational advisory services to operating entities across the Secretariat, including other departments, offices-away-from headquarters, field missions, and regional commissions. DSA oversees a range of specialized or crosscutting operational capacities. A large part of its responsibilities is to support start-up, surge, transition and liquidation requirements and to exercise authority on behalf of entities to which authority has not been granted owing to a lack of capacity or from which authority has been temporarily withdrawn. S/RES/2699 (2023) was adopted by the Security Council on 2 October and authorized Member States to form and deploy a Multinational Security Support (MSS) Mission to support the efforts of the Haitian National Police to re-establish security and build security conditions conducive to holding free and fair elections in Haiti. Paragraph 16 of S/RES/2699 (2023) requests the Secretary General to establish a Trust Fund as a mechanism that can facilitate voluntary contributions to the MSS to enable and operationalize the mandate. DOS is the Programme Manager of the Trust Fund. The focus of this role is to lead substantive engagement and coordination of the Trust Fund activities. The Senior Programme Officer will report to the Chief of Service.
