Job Title: Optimization Consultant

Type of Contract: International Consultant

Division: NUT - Nutrition Division

Duty Station (City, Country): Home-based

Duration: 8 months, with possible extension to 11 months


Ensuring a diverse and healthy diet for our growing world population through sustainable food systems is one of the greatest challenges of our times. This is particularly true in low- and middle-income countries (LMICs), where undernutrition remains a major problem due to diets that are often not diverse enough, lack adequate protein quality and micronutrients, and may also be insufficient to meet energy needs. Furthermore, climate change and shocks also affect food systems, affecting diets and requiring diverse adaptations. Food supply and demand challenges encompass the linkages between health, food, purchasing power, and the environment. Food and diets have a direct impact on human health and environmental sustainability.

Providing an increasing population with diets that address multiple urgent priorities—nutrition, affordability, adaptation to climate change as well as the need to mitigate agriculture’s contributions to greenhouse gas emissions (GHGe), biodiversity loss, soil erosion, freshwater depletion, zoonosis, antimicrobial resistance, and other areas of public health and ecological concern—will require the development of long-term and context-appropriate strategies for the different components of the entire food system. It is essential to acknowledge that transitioning to sustainable healthy diets might lead to an increase in GHG emissions in LMICs, making it crucial to balance environmental and nutritional objectives.

The ENHANCE project envisions the use of analytics to address the challenge of achieving an affordable healthy diet whilst limiting the environmental impacts. ENHANCE aspires to be an open-access platform for data-analysts and policymakers that brings together data from different domains to compare dietary scenarios for their different impacts. Multi-objective linear optimization will allow users to explore synergies and trade-offs between cost, environmental impact, dietary preferences, and nutrient adequacy of dietary scenarios, generating evidence to inform actions and policies for food systems transformation.

The four partners currently involved in the project are Capgemini, Johns Hopkins University, the Zero Hunger Lab of Tilburg University (ZHL), and the United Nations World Food Programme (WFP). Each partner brings a combination of specific subject matter knowledge, data science and/or end-user expertise and platforms, as well as specific capacity to work on the solution.

A first prototype of the tool was developed in 2022 and new iterations are currently under development. To support this exciting project, ENHANCE is looking for a consultant to join the product development team and support the development and integration of the solution’s optimization algorithm in collaboration with WFP, ZHL and Capgemini. The consultant will be expected to take part in the sprint process which take place in the mornings in Western Europe, where the ENHANCE team is located, and evolve with limited supervision. Therefore, the consultant should ensure adequate overlap of work hours between Western Europe and their location.


  1. Support the development and rollout of the ENHANCE optimization algorithm, including:

    1. Incorporating new features to the web application and its mathematical optimization algorithm based on WFP and additional external use cases;
    2. Testing and validating new features to ensure quality, consistency, and the alignment with best practices on agile development;
    3. Develop and maintain the data pipeline for the tool;
    4. Supporting WFP teams during analyses to ensure the outputs are correct, and to diagnose and resolve issues that may arise;
    5. Improving the user experience and interaction with the algorithm, particularly through the definition and inclusion of tailored error and warning messages when optimization fails or is incomplete;
    6. Contributing to deep dives on WFP business requirements to evaluate further optimization improvements and opportunities. To the extent possible, recommend system and/or process enhancements to further improve ENHANCE tool performance;
    7. Producing documentation and guidance materials as it relates to the optimization algorithm and its uses, such as manuals on the developed tool.
