• Support data exchange between instrument software, backend services, and Laboratory Information Systems (LIS), where applicable.
• Work with data formats and interfaces such as JSON, XML, CSV, REST APIs, and relevant laboratory communication protocols.
• Ensure consistency and traceability of diagnostic data across software modules and system components.

Data Security, Reliability & Quality

• Assist in implementing database backup, recovery, and data integrity mechanisms.
• Support transaction handling and recovery strategies to minimize data loss and maintain system consistency.
• Follow appropriate access control, authentication, authorization, and secure data handling practices.
• Support audit trail and event logging requirements wherever applicable to diagnostic software workflows.
• Participate in software testing, database validation, defect investigation, and root-cause analysis.
• Follow applicable software development lifecycle (SDLC) practices and contribute to compliance with IEC 62304 and ISO 14971 requirements under the guidance of senior engineers.

Cross-Functional Collaboration & Documentation

• Collaborate with application developers, embedded software engineers, hardware teams, system engineers, and verification and validation teams.
• Support integration testing between backend services, SQL databases, and diagnostic instrument applications.
• Prepare database design documents, technical specifications, test cases, and troubleshooting reports.
• Maintain version control for database scripts and support controlled software releases.
• Participate in code reviews and follow established development standards.

Innovation & Continuous Learning

• Contribute to R&D initiatives focused on diagnostic automation, laboratory data management, and next-generation healthcare technologies.
• Explore opportunities to improve database performance, data processing efficiency, and backend reliability.
• Support feasibility studies, proof-of-concept development, and new software feature implementation.
• Continuously enhance technical knowledge of database technologies, backend development, and medical device software engineering.
