Application Software Engineering

Role Summary

Design, develop, and maintain application-layer software that enables system operation,

configuration, communication, diagnostics, and customer-specific functionality for power

electronics products and energy systems, acting as the bridge between embedded control,

PLC/SCADA, and end-user interfaces.

Key Responsibilities

1. Application Logic & System Behaviour

• Develop application-level logic for:

• System operating modes and sequencing

• State machines and interlocks

• Alarm, event, and fault management

• Implement parameter management, configuration, and variant handling.

2. Communication & Integration

• Develop and maintain communication interfaces: Modbus RTU / TCP, CAN /

CANopen

• Ethernet-based protocols (OPC UA desirable)

• Integrate application software with:

• Embedded controllers (DSP / MCU)

• PLC & automation systems

• SCADA / EMS platforms

3. HMI & User Interaction

• Support local HMI functionality:

• System configuration & diagnostics

• Commissioning and service workflows

• Coordinate with SCADA teams for remote monitoring and control requirements.

4. Commissioning & Field Support

• Support FAT, SAT, and site commissioning activities.

• Troubleshoot application-level and integration issues.

• Support firmware updates, configuration changes, and upgrades.

5. Testing, Quality & Documentation

• Perform unit and integration testing.

• Support system-level validation and regression testing.

• Maintain software documentation, version control, and release notes.

• Follow SDLC, coding standards, and cybersecurity guidelines.

6. Cross-Functional Collaboration

• Work closely with:

• Control & embedded software engineers

• System engineering

• PLC / SCADA engineers

• Testing & validation teams

• Support customer technical discussions and issue resolution.

Organization Scope

• Role Scope: Product application software ownership
