Job Responsibilities:

• Build data pipeline components that normalize, process, and route telemetry from field devices to platform services and 3D visualisation layers;
• Integrate AI coding tools (e.g. Claude, Copilot) into daily development workflows for code generation, unit testing, and validation — this is an expected practice, not optional;
