Note: The job is a remote job and is open to candidates in USA. Nexleaf Analytics safeguards public health in low- and middle-income countries by providing remote-temperature monitoring for vaccine cold-chain equipment. They are seeking a Senior Software Engineer, AI & Backend to design and scale a cloud platform connecting IoT devices and developing AI-driven decision tools for health agencies.

Responsibilities

• Architect and ship AI-driven features — RAG pipelines and agentic workflows that take action across systems with human oversight where it matters
• Build the backend and infrastructure to run these reliably and at scale, across tens of thousands of IoT devices and low-connectivity environments
• Define what "good" looks like for our AI systems — holding them to real accuracy and impact standards, not demo performance
• Own large parts of the system end-to-end, from architecture to production reliability
• Work closely with product and data science to iterate fast and keep solutions aligned with product vision and real public-health needs

Skills

• Expert-level Python and backend engineering, with a track record of scalable production services
• Proven, in-production experience with RAG (retrieval, embeddings, vector stores)
• Hands-on experience building agentic systems — multi-step, tool-using AI that takes action, not just chat
• Strong grasp of the infrastructure to run AI in production reliably at scale (cloud, AWS/GCP)
• Demonstrated experience evaluating AI systems for accuracy and real-world impact, and iterating on results
• Preference for candidates based in the time zones from the U.S. Eastern through East Africa (UTC-5 to UTC+3)
