DESCRIPTION OF DUTIES:

1. Objective of the Department

 

The Information Technology Services Department (ITS) provides leadership and direction in the deployment of information and communication technologies and systems to support the Pan American Health Organization/Regional Office of the Americas of the World Health Organization (PAHO/WHO) in carrying out its mandate. ITS establishes and maintains strategies, policies, standards, and procedures to ensure the effective and efficient provision of information and communication services in a geographically dispersed environment.

 

2. Purpose of the Consultancy

 

The Pan American Health Organization (PAHO) is seeking an experienced Senior Drupal Developer consultant to support the ITS Web Services team in leading the architecture, development, maintenance, and strategic enhancement of PAHO's digital web presence. The Senior Drupal Developer will serve as the technical lead on a broad portfolio of web properties including seven (7) Drupal-based websites and approximately forty (40) additional sites, including static sites and applications built with Angular.js and React.js.

 

PAHO's combined web portfolio receives approximately 4 to 5 million visits per month, serving health professionals, researchers, government bodies, and the general public across the Americas and beyond. This level of traffic underscores the critical importance of site reliability, performance, security, and availability. The Senior Drupal Developer must bring the seniority, technical depth, and leadership maturity required to maintain and evolve high-traffic, mission-critical public health web infrastructure.

 

In addition to hands-on development, this consultant will provide technical guidance to junior developers, lead architectural decision-making, enforce code quality standards, and serve as the primary technical point of contact for the ITS web development team. They will work within an agile, Kanban-driven environment and play a key role in managing the full deployment pipeline.

3.1 Technical Leadership & Architecture

• Serve as the technical lead for all Drupal development activities across the ITS web portfolio, providing architectural direction and decision-making.

• Define and enforce coding standards, development best practices, and technical guidelines for the web development team.

• Lead architectural planning for new features, site builds, and platform upgrades — including evaluating module selections, data modeling, and integration strategies.

• Conduct thorough code reviews for all team members, providing constructive feedback to ensure quality, security, and maintainability.

• Mentor and support junior Drupal developers, facilitating knowledge transfer and professional growth.

• Collaborate with the ITS team lead and stakeholders to translate business requirements into scalable technical solutions.

• Proactively identify technical debt, propose remediation plans, and lead refactoring initiatives.

• Act as deployment coordinator for production releases — managing multi-project release sequencing through the CI/CD pipeline.

 

3.2 Advanced Drupal Development & Site Management

• Design, develop, and maintain custom Drupal modules, themes, and content architectures for seven (7) Drupal 9/10/11 websites.

• Write and maintain advanced PHP code for custom Drupal modules, hooks, APIs, and integrations, following Drupal and Symfony coding standards.

• Develop and maintain Twig templates for Drupal theming, including complex template overrides, preprocess functions, and theme hooks.

• Leverage Symfony components (HttpFoundation, EventDispatcher, DependencyInjection, Routing) fo
