The Facility provides demand-driven technical assistance, strengthens institutional capacity, and facilitates knowledge and skills exchange across countries in the region. The Facility is envisioned as a five-year initiative, initially serving countries in the Eastern Caribbean eligible for Official Development Assistance, namely Dominica, Grenada, Saint Lucia, and Saint Vincent and the Grenadines. Through a growing number of short- and medium-term technical assistance assignments and surge deployments, the Facility is expected to strengthen the capacity of ministries, project implementation units, and utilities responsible for delivering climate-resilient infrastructure in these countries. The Facility will be implemented through a United Nations Office for Project Services (UNOPS) Hosted Entity Partnership, which will provide the institutional platform required for the Facility’s establishment and early operations. ### Role Purpose The functions/responsibilities/key results of this job description are generic and may not always be applicable, nor be comprehensive, for all assignments and/or missions under this job title. The specific tasks and deliverables for each retainer assignment may vary and will be detailed in the terms of reference developed for each assignment by the RIISE Secretariat. The RIISE Facility delivers demand-driven technical assistance primarily through two service modalities: the Rapid Helpdesk, which provides short-term remote advisory support for urgent queries, and Surge Deployments, which involve medium-term engagements designed to resolve complex project execution bottlenecks. While RIISE operates on a "remote-first" delivery approach—utilizing digital collaboration tools by default to optimize responsiveness and cost-efficiency—the Consultant must possess the availability and willingness to travel for on-site deployments across participating Caribbean countries. In-country field presence remains a fundamental requirement for complex assignments where direct hands-on engagement, collaborative work with government counterparts, and on-site technical assessments are critical for effective problem resolution. While the contract modality for this Vacancy Announcement is an ICA retainer contract on project or assignment basis, UNOPS may offer on a need basis a full-time employment for a specified consecutive period of time (up to one year maximum, with possible extensions) - with the possibility to go back and forth between the two contract modalities, pending acceptance of the incumbent of the assignments proposed to him/her. ### Functions / Key Results Expected The specific tasks for each assignment may vary from one assignment to another assignment. Under the overall guidance and direct supervision of the RIISE Secretariat and designated Supervisor, the Specialist will work on a retainer contract and will be called upon for specific projects to fulfill one or more of the following key tasks: 1. Planning and Implementation - Lead the planning and technical implementation of infrastructure activities in alignment with applicable standards and project objectives. - Conduct and oversee site investigations, including topographic surveys, geotechnical assessments and feasibility studies. - Review and validate design documentation, drawings, technical specifications and tender dossiers to ensure quality, constructability and compliance with regulations. - Provide expert technical advice to the project manager and stakeholders on all engineering-related matters. - Contribute to developing detailed project work plans, identifying dependencies, and defining clear milestones, deliverables and risk mitigation strategies. 2. Construction Supervision and Quality Management - Lead and coordinate supervision of contractors and consultants to ensure compliance with approved designs, contracts and technical specifications. - Implement and monitor Quality Assurance/ Quality Control (QA/QC) systems and procedures.
