We are seeking a Senior Backend Software Engineer to join the development team of one of our client’s robust, scalable backend systems that power a patient-centric platform.

This role is crucial in designing and implementing the core infrastructure that enables seamless data integration, analysis, and AI-driven insights across the ecosystem.

The key responsibilities of this role will be as follows:

  • Architect and implement high-performance, scalable backend solutions using modern technologies, healthcare interoperability standards like FHIR, and advanced AI/ML technologies
  • Lead the design and development of RESTful APIs and microservices that support our patient, partner, and internal-facing applications
  • Integrate and optimize AI models, particularly Large Language Models (LLMs), using frameworks like LangChain and LlamaIndex
  • Implement Retrieval-Augmented Generation (RAG) systems to enhance the accuracy and relevance of AI-generated insights in the healthcare context
  • Design and implement efficient data pipelines to support AI model training and inference
  • Optimize data processing and storage solutions to handle large volumes of complex health data efficiently
  • Collaborate with data scientists and researchers to implement advanced analytics and AI models that derive insights from patient data
  • Ensure the highest standards of data security and privacy compliance
  • Lead efforts to enhance system reliability and performance, including implementing monitoring, logging, alerting and auto-scaling systems for both traditional backend services and AI components
  • Participate in code reviews to ensure high code quality, maintainability, and adherence to best practices across the team
