Senior Software Engineer, Backend

Job Description

Join Our Mission

Nexleaf Analytics is at the forefront of technological innovation, committed to safeguarding public health in low-and middle-income countries. Our cutting-edge solutions, including remote-temperature monitoring for vaccine cold-chain equipment, are operational in over 25 countries, fundamentally supporting vital health infrastructure.

Nexleaf is poised to expand its impact significantly in 2025 and beyond. Data on the performance and utilization of medical equipment is becoming increasingly available, but countries are struggling to integrate and apply this data for action. Nexleaf envisions a ‘Connected Clinic’ – a transformative concept aimed at fostering transparency, accountability, and enhanced health outcomes through the strategic use of data. We believe this approach will shape health services in a way that prioritizes local needs and sustainability, moving beyond donor-driven models to ones that truly resonate with the communities we serve.

As a Senior Software Engineer, Backend at Nexleaf you’ll help us achieve scale and impact by serving as a leader on a team that designs and develops the core backend code of our cloud-based web service. This service collects and analyzes data gathered from the hardest to reach places on Earth and connects to tens of thousands of IoT/M2M devices across the globe. These data and services are accessed by users spanning Ministries of Health, global agencies, partner NGOs, and those working in remote, low connectivity environments.
