全职 Backend Systems Engineer - Contract 工作, 薪水 up to SGD 6,000, ZENITH INFOTECH (S) PTE LTD. Islandwide (Singapore) 公司招聘中 - Ricebowl

Role Overview

Join the Software Engineering team on a physical Operations Technology (OT) integration project. You will build and maintain the backend systems that connect OT field devices to the digital twin platform — handling real-time data ingestion, protocol translation, and system integration across industrial communication standards.

Key Responsibilities

• Develop and maintain backend services and middleware for OT/IoT data ingestion using OPC-UA, MODBUS, and MQTT protocols.

• Build data pipeline components that normalise, 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.

• Write and maintain automated test suites covering protocol adapters, data transformation logic, and integration endpoints.

• Collaborate with frontend Unity engineers and systems architects to define and implement API contracts (REST/WebSocket).

• Participate in code reviews, contribute to technical documentation, and support deployment through CI/CD pipelines.

• Troubleshoot field connectivity and protocol issues; work with OT/hardware teams on device commissioning and debugging.

Must-Have Requirements

• Hands-on experience with OPC-UA, MODBUS, and MQTT — protocol implementation, not just conceptual familiarity.

• Proficiency in backend development (Python, Node.js, Go, or Java — at least one).

• Active use of AI tools for coding, testing, and validation in prior roles or personal projects.

• Experience writing integration and unit tests; familiarity with test automation frameworks.

• Comfortable working with message brokers (MQTT brokers, Kafka, or similar) and time-series or event-driven data.

Good to Have

• Exposure to digital twin platforms or industrial IoT stacks.

• Familiarity with OT security considerations (network segmentation, secure protocol configuration).

• Experience with containerisation (Docker/Kubernetes) and CI/CD tooling.

• Knowledge of BACnet, DNP3, or other industrial protocols.

Experience

• 2–5 years in backend or systems software engineering, with at least some exposure to OT/IoT environments.

• Degree in Computer Science, Engineering, or equivalent practical experience.
