[Hiring] IoT / Edge Software Engineer @NTT DATA Services

Role Description

The IoT Edge Software Engineer is responsible for the design, development, deployment, and maintenance of edge software components that enable secure, reliable, and scalable integration between field-deployed dosimeter devices, gateways, and cloud environment. This role is central to the modernization of client's radiation exposure management, focusing on the implementation and optimization of AWS Greengrass-based IoT gateway solutions, Bluetooth Low Energy (BLE) device communication, and secure data transmission protocols.

The engineer works closely with system architects, backend/API engineers, and operational stakeholders to ensure that edge software components support:

• Real-time dosimeter data ingestion
• Device management
• Firmware updates
• Operational status monitoring in compliance with cybersecurity and privacy requirements

The IoT Edge Software Engineer is responsible for developing and maintaining software modules that run on Linux-based gateway hardware, supporting features such as:

• Device authentication
• Data encryption
• Remote updates
• Automated diagnostics

The position requires hands-on experience with embedded Linux, MQTT messaging, and integration with AWS IoT Core, as well as the ability to troubleshoot and optimize edge-to-cloud workflows for performance, reliability, and security. The engineer ensures that all edge software is auditable, maintainable, and aligned with the mission-critical needs of operational communities, supporting both connected and disconnected operational scenarios.

This role is essential for delivering a robust, secure, and resilient edge computing infrastructure that enables client to provide accurate, timely, and actionable radiation exposure data across enterprise.
