Key Responsibilities
Design and maintain backend architectures for internal business systems and external client platforms.
Oversee database design, configuration, optimization, backup and data‑cleanup procedures, ensuring data integrity and efficient performance under load.
Develop and maintain system integration layers (e.g. integrate third‑party services, external APIs, external data sources, IoT or data‑collection endpoints), and ensure stable inter‑system communication.
Implement and maintain security measures and access control (RBAC or similar), ensure compliance with applicable regulations or internal policies.
Monitor system performance, troubleshoot issues (bugs, latency, data errors), implement fixes, and run regular maintenance.
Develop or support internal automation tools, scripts for system monitoring, log analysis, data processing, and operational tasks.
Prepare and maintain technical documentation: architecture diagrams, API specs, data dictionaries, system configuration guides.
Collaborate with other teams (operations, support, client‑facing, possibly data/analytics) to ensure the systems effectively support business needs, but focus remains on engineering, technical delivery rather than project management or coordination.
Participate in system upgrades, migrations, and infrastructure improvements.
