About One Acre Fund

Founded in 2006, One Acre Fund equips 5.5 million smallholder farmers to make their farms more productive. Across nine countries that together are home to two-thirds of Africa's farmers, we provide high-quality farm supplies, tree seedlings, accessible credit, modern agronomic training, and a wide range of other agricultural services. On average, this model enables any farmer to increase their income and assets on supported land by more than 35 percent, while permanently improving their resilience. This is all made possible by our team of 9,000+ full-time staff, drawn from diverse backgrounds and professions. To learn more, please see our Why Work Here blog post.

About the Role

From R&D to sales to strategy to operations, the Global R&D Data Analyst has the unique opportunity to improve decision-making across all aspects of One Acre Fund’s program using many diverse data types, such as sales, yield, demographic and satellite data, to help us reach more farmers with greater impact. 

The Global R&D Data Analyst will help us reach over one million farmers by executing analyses for strategic decision-making on repayment, expansion, and other business functions, and work directly with program leaders to interpret results and make data-driven decisions. The Global R&D Data Analyst will play an integral role in shaping One Acre Fund’s data strategy, including dreaming up and executing new ways to use our data to improve our program.

Additionally, One Acre Fund has a robust agronomic and socioeconomic research program spanning all countries of operation. This role will work closely with country R&D teams to ensure all trials are executed at the highest possible standards, provide follow-up analytical support and training to team members, and support with warehousing of our agronomic data to make our research outputs accessible to external collaborators, further increasing One Acre Fund’s smallholder farmer impact across the continent.

To succeed in this role, you will need to be a strong communicator and have a solid analytical background with experience in experimental design. You will need to be comfortable interpreting ambiguous results generated with imperfect data and advising leaders on the relative risk associated with different decisions based on the results of your analysis. 

This is a deliberately hybrid role. Success requires the ability to operate effectively as:

• an experimental methodologist (trial design & causal inference),
• an applied data scientist (production analytics, geospatial methods, modelling), and
• a delivery-oriented project manager (prioritisation, documentation, coordination).

Responsibilities

Own methodological rigour and analytical quality for trials and surveys (30%):

• Design and analyse trials and surveys, including:
  • Sample size and power calculations
  • Stratification and experimental design
  • Recommend the appropriate statistical methods (e.g., hypothesis testing, regression, ANOVA/mixed models)
• Lead analysis of agronomic and product trials to estimate treatment effects and program impact
• Quality assure trial designs and analyses produced by other analysts
• Translate trial findings into clear recommendations for product design, agronomic guidance, and program strategy.

Develop scalable analytical products and decision-support tools using program, survey, and spatial data (30%):

• Build, maintain, and improve analytical pipelines and production codebases that power operational decision tools (e.g., sowing date or input recommendations), including occasional support at the production level.
• Integrate survey, MEL, and operational data with geospatial layers (soil, climate, vegetation, remote sensing) to generate localised recommendations and program targeting strategies.
• Conduct spatial and remote-sensing analyses for program design, prioritisation, and impact estimation (e.g., soil erosion modelling, site suitability analysis).
• Analyse historical trial and soil data to generate input and soil management recommendations (e.g., lime application, fertiliser rate application).
• Evaluate potential impact of alternative interventions and support pilot design, iteration, and scale decisions.
• Translate analyses into decision-ready outputs (briefs, dashboards, and memos) for non-technical stakeholders.
• Identify new, high-leverage analytical use cases that improve program reach, impact, or cost-effectiveness.

Lead impact data management and project management (~20%)

• Lead curation and standardisation of historical yield, agronomic practice, and trial datasets to enable reuse and external research collaboration.
• Own knowledge management for impact data and trials, including:
  • Central documentation of methodologies, assumptions, sample sizes, and results for all projects
  • Reusable analysis templates and reference implementations
• Manage external data requests in compliance with client data protection and confidentiality protocols.

Provide portfolio-level project management (~20%):

• Maintain project plans, priorities, and timelines
• Track dependencies and risks
• Coordinate with program and R&D stakeholders to identify potential delivery risks
• Establish durable documentation and planning systems (e.g., project roadmaps, project trackers, shared repositories).

Career Growth and Development

We have a strong culture of constant learning, and we invest in developing our people. You’ll have weekly check-ins with your manager, access to mentorship and training programs, and regular feedback on your performance.

About Sand

Sand Technologies is a global Physical AI company using data and AI to make critical industries work better. We partner with governments, cities and enterprises to improve how essential systems operate across healthcare, water, energy, telecommunications and infrastructure.

Our work delivers proven real-world impact. We have built AI systems that help manage London’s water supply, supported telecom network planning across hundreds of cities, and developed digital healthcare platforms serving tens of millions of people across Africa. From intelligent command centers to AI-powered infrastructure platforms, we help organizations sense, analyze and act in complex environments.

Our people are ambitious, curious and relentlessly practical. Our teams work alongside clients in the field, solving hard problems and deploying solutions that last. With colleagues across Africa, Europe, the UK and the US, we operate across the full stack - from research and engineering to deployment and capability building.

Our mission is simple: to harness AI to solve humanity’s most pressing challenges.

About the role

Sand is scaling rapidly across Africa, partnering with Ministries of Health to deploy the Health Operating System (HOS) — a decision-support and execution platform that transforms how health systems sense, analyze, and act on data. The HOS is already operational across multiple countries, with plans to expand to 15 countries by end of 2026, supported by 80+ Forward Deployed Engineers.

As a Forward Deployed Engineer (FDE), you are the technical spearhead of our client engagement in Kenya. Unlike our roaming FDE roles, this is a permanently embedded position. You will be based full-time within the Ministry of Health in Kenya, becoming a long-term extension of the client's operational team. Your mandate is to build deep institutional relationships, develop comprehensive understanding of the national health system, and deliver sustained value over an extended engagement — not just rapid sprints, but lasting transformation.

This is not staff augmentation. You are an amalgamation of three roles:

1. The Software Engineer — Deep technical acumen to build and deploy production-grade solutions using Sand's product suite
2. The Product Manager — Strategic foresight to understand client problems, influence business objectives, and identify expansion opportunities
3. The Consultant — Client-facing finesse to navigate complex stakeholder relationships, manage scope, and transfer knowledge

Your primary mission is to prove our value fast, delivering functional solutions rapidly using Sand's products, playbooks, and tools, and then maturing those solutions into mission-critical infrastructure that the Ministry depends on daily. Over time, you become the institutional memory of the deployment — the person who understands the data landscape, the stakeholder dynamics, and the operational realities better than anyone.

Who We're Looking For

The Forward Deployed Engineer is a highly ambitious individual. You are someone who is deeply keen on learning — someone who dives in headfirst to solve some of the hardest, most complex problems in global health. You thrive on understanding the technology, understanding the stakeholders, understanding our product suite, and weaving all three together to deliver solutions that change how health systems operate.

This role is not for someone looking for comfort or routine. It is for someone who wants to step outside of their comfort zone, build something they can be proud of, and grow faster than they thought possible. The FDE programme is a career accelerator — an intensive rotation that exposes you to technical depth, strategic thinking, and client leadership in equal measure, all while working on problems that matter for millions of people.

For this permanently embedded role, you also need the maturity and resilience to sustain deep client relationships over months and years — not just weeks. You will become the face of Sand in Malawi, and that requires patience, cultural fluency, and the ability to navigate institutional complexity while maintaining momentum.

Key Responsibilities

Serve as Sand's Permanent Technical Presence in Kenya

• Embed full-time within the Ministry of Health, becoming a trusted member of the client's extended team
• Develop deep, longitudinal understanding of the national health data landscape, institutional dynamics, and operational priorities
• Build and maintain relationships across all levels of the Ministry — from frontline data officers to senior leadership
• Act as the primary technical point of contact for all Sand activities in-country, coordinating with launchers, country directors, and visiting FDE teams

Drive On-Site Value Delivery

• Rapidly unlock, explore, and integrate client data sources (e.g., DHIS2, SCADA systems, network management platforms, operational databases)
• Understand client problems through prototyping and rapid value delivery — deploying POCs and MVPs using Sand's product components and playbooks
• Transition initial solutions into hardened, production-grade systems that the Ministry relies on daily
• Own the long-term health of deployed solutions — monitoring adoption, troubleshooting issues, and iterating based on user feedback
• Deliver and track value generated through deployment of Sand products

Enable Product-Led Growth

• Lead with Sand's existing product suite — know the products by heart and where each solution is most effective for the domain you're deployed in
• Document learnings, client challenges, and successful solutions as reusable patterns for the broader FDE community
• Drive discovery and expansion by uncovering new opportunities on the ground

Build Local Capacity and Sustainability

• Work alongside Ministry teams to co-create solutions and progressively transfer knowledge, ensuring they can operate and maintain systems independently
• Identify, recruit, and mentor local data engineers, scientists, and analysts to build sustainable in-country capacity
• Develop training materials and documentation tailored to the local context, language, and skill level
• Be the continuity that ensures handover isn't a cliff — you bridge the gap between Sand's deployment and the Ministry's long-term ownership

Feed the Platform Feedback Loop

• Channel field learnings back to improve the core product through structured mechanisms (Technical Deep Dives, Solution Swarms, pattern documentation)
• Turn "gravel roads" into "paved superhighways" — document solution patterns so the next FDE can move faster
• Contribute field feedback that influences 30% of the product roadmap

Requirements — Essential

• Bachelor's degree in Computer Science, Engineering, Information Systems, or related technical field
• 5+ years of experience in software engineering, data engineering, data science, system deployment, or technical leadership
• Proficiency in at least one of: Python, SQL/PostgreSQL, JavaScript — with ability to write production-grade code

• Excellent communication and stakeholder management skills — comfortable presenting to senior government or corporate stakeholders and translating between technical and non-technical audiences
• Experience working with or deploying to government, public sector, or large institutional clients
• Proven ability to lead local technical teams and build capacity
• Willingness to relocate and be permanently based in Kenya for the duration of the engagement (12-24+ months)
• Language: Local language proficiency is a significant advantage

Requirements — Preferred

• Experience with data integration, ETL pipelines, and working with diverse data sources
• Experience in one or more of Sand's focus domains: health informatics/digital health, water utility operations, telecommunications network operations, or energy systems
• Familiarity with domain-specific platforms (e.g., DHIS2, OpenMRS for health; SCADA, GIS for water/energy; OSS/BSS for telecom)
• Experience with BI and dashboarding tools, particularly Apache Superset
• Experience with data transformation tools such as dbt or Airflow
• Comfort working with data dictionaries, reporting requirements, and identifying common data quality issues
• Knowledge of data security, privacy, and interoperability standards (e.g., FHIR for healthcare, GDPR, local data sovereignty requirements)
• Experience operating in resource-constrained environments (unreliable power, limited connectivity)

Work Environment

This is a permanently embedded role. You will work on-site at the Ministry of Health in Kenya 4 days per week, with 1 day for focused remote work, internal collaboration, and knowledge sharing with the broader FDE community. You should expect to be based in Kenya for a minimum of 12-24 months.

You must be self-driven, comfortable operating as Sand's primary technical representative in-country, and disciplined with online collaboration tools to stay connected with the broader Sand team across geographies. Cultural sensitivity, adaptability, and genuine interest in the local context are essential — you are not passing through, you are putting down roots.
