Job description

OBJECTIVE OF THE OFFICE/DEPARTMENT

This is a requisition for employment at the Pan American Health Organization (PAHO)/Regional Office of the World Health Organization (WHO)

Contractual Agreement: Non-Staff - International PAHO Consultant

Job Posting: August 28, 2026

Closing Date: September 7, 2026, 11:59 PM Eastern Time

Primary Location: Off Site

Organization: EIH Evidence and Intelligence for Action in Health

Schedule: Full time

PURPOSE OF CONSULTANCY

Organization: Department of Evidence and Intelligence for Action in Health (EIH) and PAHO technical teams for immunization, health analysis, and digital transformation.

The Pan American Health Organization (PAHO) supports countries of the Region of the Americas in strengthening immunization systems, epidemiological surveillance, identification of coverage gaps, and planning of interventions aimed at populations with limited access to health services.

The project seeks to identify where children who have not received the first dose of measles vaccine are concentrated (zero-dose children for measles). This information will serve as the basis for designing and implementing a cloud-based solution to support geospatial microplanning of vaccination campaigns, enabling the integration of coverage, population, health facility, priority territory, access barrier, and campaign operational results data.

Strengthening measles vaccination requires tools that can detect and prioritize territories with subnational gaps, transform fragmented data into actionable information, and support national and subnational teams in planning routes, resources, monitoring, and evaluation. The planned solution must be prepared to operate in a secure, scalable, and sustainable institutional environment, with capabilities for data ingestion, geospatial processing, APIs, authentication, traceability, monitoring, and cloud deployment.

To advance this component, PAHO requires a consultant specialized in backend architecture and cloud computing, capable of designing the technical architecture, configuring core cloud and backend components, defining integration requirements, and establishing a secure basis for further development of the vaccination campaign microplanning platform.

Purpose

Design, document, and implement the backend and cloud computing architecture for a geospatial vaccination campaign microplanning solution aimed at identifying and prioritizing areas with children who have not received the first dose of measles vaccine.

Ensure that the proposed solution is modular, scalable, secure, traceable, and interoperable with institutional data sources, including vaccination coverage, population, administrative boundaries, health facilities, operational routes, and other inputs required for microplanning.

DESCRIPTION OF DUTIES:

Responsabilities

1. Cloud and backend architecture design
   • Gather technical and functional requirements with PAHO teams and designated counterparts.
   • Define a modular cloud architecture for ingestion, processing, storage, geospatial analysis, APIs, and visualization.
   • Specify compute components, databases, geospatial services, load balancing, scaling, recovery, and operational continuity.
   • Develop logical, physical, and deployment architecture diagrams, including development, testing, and production environments.
2. Data design, interoperability, and geospatial processing
   • Design data ingestion, validation, cleaning, transformation, and versioning flows from immunization systems, population sources, health facilities, and geographic layers.
   • Define relational and geospatial data models, including standards for metadata, data dictionaries, and lineage.
   • Configure or specify geospatial databases and spatial query services that enable the identification of clusters and priority areas.
   • Design APIs for secure data exchange with analytical modules, web interfaces, and approved external services.
3. Backend prototype implementation and cloud deployment
   • Configure repositories, environments, containers, backend services, and continuous deployment pipelines in accordance with PAHO technical policies.
   • Implement minimum backend services for authentication, user administration, data upload, geospatial queries, and results export.
   • Configure infrastructure as code or equivalent documentation to reproduce environments and facilitate maintenance.
4. Security, privacy, governance, and compliance
   • Define role-based access controls, authentication, authorization, encryption, secrets management, audit logging, and environment segregation.
   • Incorporate principles of data minimization, protection of sensitive information, and privacy risk review.
   • Document security assumptions, dependencies, technical risks, and mitigation measures.

These activities are essential to ensure that the future solution can identify vaccination
