Are You Ready to Make a Real Difference? Are you a talented full-stack engineer looking to make a real difference through the application of cutting-edge technology products? Do you want to: Work on tech products that solve meaningful problems - rural water security for farmers, health outcomes for mothers, reduce gender-based violence in public spaces, reducing environmental pollution - and many others? Spend your time not just sitting in front of your screen but also immersing yourself in the field - villages, slums, schools, public buses - participating in user research to understand how the tools you develop will transform lives? Work in a collegial startup environment that equally values high performance and a nurturing environment within a growing multidisciplinary team? If this deeply resonates (and only if), we invite you to read on. About ABCD Behavior change is an important component of most development topics — healthcare, education, water & sanitation, gender, and agriculture — and several organizations in the Government, the philanthropic sector, and development work on large programs to improve outcomes in these topic areas. The Atlas for Behavior Change in Development (ABCD) aims to help such organizations run high-quality behavioral interventions that help achieve development outcomes. The Atlas is a technology platform that brings together a range of knowledge resources, cutting-edge AI tools, and networking features that enable organizations working in the impact sector to run behavioral programs more effectively and efficiently. The platform is driven by extensive secondary research, knowledge sharing through partnerships, and innovative feature development. You can visit the platform at https://abcd.guide/. The Role & Why It Matters This role will involve building key features and tools within the ABCD platform, including: Tools that promote behavior change among frontline workers (e.g., ASHA, agriculture extension workers, teachers) AI-based tools that improve the way policy and impact investments get made or development programs are designed You will play a foundational role in building these tools, working closely with the ABCD team, our partners (including behavioral researchers, designers, bureaucrats, grassroots NGOs), and will own the technology development process end to end—from architecture to deployment in production. Why This Role is Different At ABCD, we are building transformative technology for the development sector—tools that empower organizations to address some of the toughest, most meaningful challenges of our time, from improving maternal health outcomes to advancing climate resilience in farming communities. We are a small but high-performing team, blending the precision of data science with the empathy of field research, united by a shared mission to create lasting impact. End-to-End Ownership This isn't just another coding job. You'll own the full product lifecycle—from ideation and prototyping to deployment and scale. You'll build tools that are not only technically sound but also contextually relevant to real-world users. Career Acceleration You'll gain leadership experience early, working in a small team where your decisions directly influence product direction. This is a place to fast-track your growth, building not just software but also critical skills in product management, design thinking, and user-centric innovation. Diverse Collaboration Break free from the echo chamber of tech-only teams. Work closely with social scientists, designers, and behavioral researchers to understand the nuances of human behavior and design technology that truly matters.
