The Senior Software Engineer is a highly hands-on role responsible for building, deploying and operating AI-enabled healthcare products at EndeavourX. The role focuses on delivering production-quality software that integrates with real-world systems and supports deployment in regulated healthcare environments, including implementing and integrating LLM-based features.

Key Responsibilities

Software Design & Development

• Own end-to-end development of backend and full-stack components for AI-enabled healthcare products.
• Translate product requirements into well-structured software designs, APIs and data flows.
• Rapidly prototype, iterate and deploy features in response to product and clinical feedback.
• Integrate applications with external systems (APIs, data sources, healthcare platforms).

Applied AI / LLM Integration

• Implement and integrate LLM-based capabilities (e.g. retrieval-augmented generation, prompt orchestration, context management) within production applications.
• Work with data scientists to operationalise model outputs, embeddings, vector search and retrieval pipelines.
• Implement data preprocessing, chunking, indexing and retrieval logic to support RAG workflows.
• Evaluate and tune LLM-based features for latency, reliability, cost and user experience in real-world use.

Deployment & Operational Delivery

• Participate directly in deployment activities, configuration and production support.
• Ensure software is reliable, observable and maintainable in real-world use.
• Support incident investigation and resolution as needed.

Quality & Regulated Delivery Support

• Follow development and documentation practices aligned with ISO 13485 / IEC 62304.
• Maintain code quality, versioning, traceability and documentation required for regulated products.
• Participate in design reviews, risk discussions and change assessments related to clinical safety and system reliability.

Collaboration

• Work closely with the Cloud Architect, data scientists and product stakeholders to deliver end-to-end solutions.
• Review code, contribute to technical discussions and support continuous improvement of engineering practices.
• Support coordination with external development teams when required.

Job Requirements

Experience & Skills

• 5–8 years of professional software development experience.
• Strong proficiency in at least one major programming language (e.g. Python, JavaScript/TypeScript, Java).
• Experience deploying applications in cloud environments (AWS preferred).
• Experience working across the full software lifecycle, including production support.
• Experience implementing or integrating LLM-based features (e.g. RAG pipelines, embeddings, vector databases, prompt engineering).
• Familiarity with applied machine learning concepts (e.g. model inputs/outputs, evaluation metrics, data preprocessing).
• Experience working within quality systems or regulated development environments preferred.
• Experience in start-ups, healthcare, medtech, digital health or other related domains is an advantage.
