At Dexis, you will experience a corporate culture of inclusiveness, respect, fairness, and trust. You will be given the means and mentorship needed to succeed, and your creativity will be rewarded. LEAP Program Description Global Solutions Ventures (GSV) – a joint-venture partnership between ZemiTek, LLC and Dexis Consulting Group – is implementing the Long-term Exceptional Technical Assistance Project (LEAP Global), a mechanism originally used by USAID to battle against infectious diseases such as malaria, HIV/AIDS, tuberculosis, neglected tropical diseases, and pandemic influenza. As of July 1, 2025, LEAP Global transitioned to the U.S. Department of State (DOS). This initiative aims to address the complex human resource challenges faced by national infectious disease programs in the USA-supported countries. The intervention of this project is to hire and embed technical expert advisors and subject matter experts within government entities. By directly embedding the technical expertise within the national programs, LEAP provides long-term, sustainable lifesaving support to empower host governments to lead and manage key aspects of their infectious disease portfolios and improve coordination between the U.S. Government and the host country. About the Position The Directorate of Maternal, Child, Adolescent and Youth Health (DSM/E/A/J) is responsible for implementing public health policies related to maternal and child health.

Location: Niger Dexis is a dynamic professional services firm dedicated to partnering with government and community leaders both in the U.S. and internationally to achieve critical social outcomes in a rapidly changing world. At Dexis, you will experience a corporate culture of inclusiveness, respect, fairness, and trust. You will be given the means and mentorship needed to succeed, and your creativity will be rewarded. LEAP Program Description Global Solutions Ventures (GSV) – a joint-venture partnership between ZemiTek, LLC and Dexis Consulting Group – is implementing the Long-term Exceptional Technical Assistance Project (LEAP Global), a mechanism originally used by USAID to battle against infectious diseases such as malaria, HIV/AIDS, tuberculosis, neglected tropical diseases, and pandemic influenza. As of July 1, 2025, LEAP Global transitioned to the U.S. Department of State (DOS). This initiative aims to address the complex human resource challenges faced by national infectious disease programs in the USA-supported countries. The intervention of this project is to hire and embed technical expert advisors and subject matter experts within government entities. By directly embedding the technical expertise within the national programs, LEAP provides long-term, sustainable lifesaving support to empower host governments to lead and manage key aspects of their infectious disease portfolios and improve coordination between the U.S. Government and the host country. About the Position Niger submitted a request to Gavi for support in optimizing Cold Chain Equipment (CCEOP). This submission includes a renewal and equipment allocation plan at the operational level over five years, from 2017 to 2021. With UNICEF’s support, Niger updated the inventory of cold chain equipment in May 2017. The update revealed gaps in geographic coverage, storage capacity, and conservation capacity both at district levels and service delivery points, including Integrated Health Centers (CSI) and health posts (HP). The platform will enable the country to improve its supply chain and cold chain by increasing coverage with certified refrigerators and contribute to efforts to strengthen vaccination coverage and equity. The Directorate of Immunization (DI) is responsible for implementing the Expanded Program on Immunization (EPI) across its five components. DI must guarantee the supply and quality of vaccines up to the last mile of the supply chain, to ensure continuity of vaccination services. Vaccines are biological products requiring the availability and functionality of cold chain equipment (CCE) to ensure their effectiveness. Niger has adopted a policy promoting the use of new technologies, including solar-powered refrigerators, refrigerators with cooling jackets, and freezers for which this CCEOP support request was submitted to Gavi in October 2016. The updated inventory documented that at the service delivery level, 3,767 structures were recorded, including 1,361 Integrated Health Centers (CSI) and 2,409 other service delivery structures (health posts, clinics, and hospitals) that provide vaccination services. Among these structures, 2,491 (66%) have equipment, including 1,322 CSIs (35%) and 1,169 other structures (31%). Furthermore, a total of 1,279 structures (34%) has no cold chain equipment (refrigerator), including 39 CSIs (1%) and 1,240 other structures (33%). Of the total 4,046 cold chain equipment units: 2,899 (72%) are solar refrigerators, 950 (23%) are electric 197 (5%) are gas-powered. Among these, 279 units (7%) must be discarded due to obsolescence or irreparable complex failures. In implementing this project, UNICEF plays an important role in managing procurement, from ordering to installation of equipment at districts and CSIs. UNICEF, through its supply center, handles procurement and has contracted two manufacturers (represented in Niger by two service providers), to implement the equipment operational deployment plan submitted by DI. To support this effort, the U.S. State Department, through the LEAP project, is providing the Directorate of Immunization with a National Technical Assistant (TA) to help implement the CCEOP2 operational deployment plan, oversee installation and user training, support GEV preparation, and monitor vaccine management for a period of at least one year. The Advisor will support the Immunization Directorate in carrying out life-saving humanitarian assistance (LHA) service delivery in full alignment with the new Presidential Executive Order (EO) directives. Responsibilities General Objective The Technical Assistant will support implementation of CCEOP2, monitoring of the vaccine supply chain, and the cold chain.
