WHY JOIN WFP?
JOB TITLE: Hydrologist
TYPE OF CONTRACT: International Consultant Level II (CST- ll)
UNIT/DIVISION: Engineering Unit (Cross-Functional) / South Sudan Country Office
DUTY STATION (City, Country): Juba, South Sudan
DURATION: 11 Months (renewable subject to performance and funding availability)
BACKGROUND AND PURPOSE OF THE ASSIGNMENT
Country Context:
South Sudan presents one of the most logistically challenging operational contexts in the world, characterised by severe infrastructure gaps, demographic constraints, ongoing insecurity, and a highly seasonal climate. Roads and other basic infrastructure are inadequate for the delivery of humanitarian cargo and are heavily affected by seasonality, with the rainy season (May to November) rendering nearly 70 percent of the country inaccessible by road. Over several consecutive years, large-scale flooding has ravaged road networks, submerged docking ports, inundated communities and assets, and repeatedly forced WFP to adapt its modes of transport to sustain operations. Water — its excess, its movement, and its variability — is therefore a defining factor across almost every dimension of WFP’s work in the country.
WFP South Sudan – A Cross-Functional Mandate:
The Engineering Unit within WFP South Sudan implements and manages a diverse portfolio of infrastructure projects in support of humanitarian operations and community resilience. The portfolio spans roads, bridges, airstrips, flood-protection structures (dykes and embankments), drainage systems, ports and river-transport infrastructure, warehouses, offices, accommodation facilities, water supply and sanitation systems, and other operational assets.
These engineering assets exist to serve a wider operation, and flood and water-related risk cuts horizontally across the entire Country Office. Functional roads, airstrips, ports, and warehouses enable the Supply Chain and Logistics functions to pre-position food, open and maintain access corridors, and sustain river and road transport to the most remote areas — particularly during the rains, when access deteriorates rapidly. The Management Services function depends on safe, well-sited, and flood-protected offices, accommodation, and field hubs for staff welfare and operational continuity. Programme and climate-finance teams require sound hydrological and climate-risk evidence to design resilient interventions, mobilise adaptation financing (including instruments such as the Green Climate Fund), and engage Government on shared water and disaster-risk priorities.
Given the scale and recurrence of flood-related risk, and the way it affects all of these functions, WFP South Sudan seeks to engage a qualified Hydrologist to provide a single, authoritative source of hydrological, hydraulic, flood-risk, and climate-resilience expertise that can be deployed flexibly wherever it is needed. The role is deliberately cross-functional: it is hosted within the Engineering Unit for technical coherence but supports Engineering, Supply Chain and Logistics, Management Services, and Programme / Climate Finance, as well as Government and inter-agency engagement.
Background and Purpose of the Assignment
The Hydrologist will provide hydrological and hydraulic expertise across the WFP South Sudan operation — supporting the planning, assessment, design, implementation, monitoring, and sustainable operation and maintenance of infrastructure and access assets, strengthening flood-risk management and climate adaptation, and serving as a technical focal point for engagement with the Ministry of Water Resources and Irrigation and other relevant Government bodies.
Working under the technical direction of the Head of Engineering and in close collaboration with the Supply Chain and Logistics, Logistics Cluster, UNHAS, Management Services, and Programme functions, the incumbent will deliver clear, documented technical assessments, modelling outputs, and mapping on request to support assessments, implementation, and monitoring across units, and will provide authoritative advice during project conception, implementation, operation, and maintenance.
The Hydrologist will, where the works require, spend a significant proportion of time (up to approximately 75%) in field locations across South Sudan, including flood-prone and remote areas.
REPORTING LINE
The Hydrologist reports to the Head of Engineering and works closely with engineering staff, the Supply Chain and Logistics, Logistics Cluster, UNHAS, Management Services, Programme functions, government counterparts, consultants, contractors, UN agencies (including UNMISS), and development partners.
