Job description

Role Summary

Build and maintain the embedded software stack for the Delta Unit Controller, the skid-level brain that coordinates PCS, BMS, and HVAC and exposes a clean interface to the upstream RT and SCADA. You will lead the platform of the developed code base onto Delta US hardware, set up modern CI/CD on Azure DevOps, and deliver IEEE 1547-2018 / UL 1741-SB compliant firmware.

Key Responsibilities

• Develop firmware/middleware for the Unit Controller in C/C++ (and Rust where appropriate) on Linux / RTOS targets (Yocto, FreeRTOS, Zephyr).
• Receive and re-platform the existing Taiwan Unit Controller code base; refactor for US PCS/BESS vendors and US standards.
• Implement Modbus TCP/RTU, IEC 61850 (client), CAN, and OPC UA stacks; integrate with PCS, BMS, HVAC, and meters.
• Stand up CI/CD pipelines on Azure DevOps with self-hosted build agents, automated unit tests, static analysis (MISRA, Coverity), and HIL-in-the-loop gates.
• Implement secure boot, signed OTA updates, role-based access, audit logging — aligned to IEC 62443-4-1/-4-2 and NERC CIP where applicable.

Required Qualifications

• BS/MS in Computer Engineering, Electrical Engineering, or Computer Science; 5+ years in embedded software for industrial / energy systems.
• Expert in C/C++ on Linux and/or RTOS; strong with multithreading, real-time scheduling, IPC, and deterministic networking.
• Industrial protocol experience: Modbus TCP, IEC 61850 (MMS/GOOSE client), DNP3, OPC UA, CAN.
• Modern DevOps: Git, Azure DevOps or GitHub Actions, Docker, Yocto build systems, hardware-in the-loop test rigs.
• Cybersecurity fundamentals: secure boot, TLS/mTLS, signed updates, key management.
