Requirements

About the Role

We are looking for an experienced Senior Embedded Software Engineer with strong hands‑on expertise in low‑level embedded programming using Texas Instruments Sitara processors and TMS320F28388D DSPs.

You will join an engineering team developing real‑time firmware for power electronic equipment. The system architecture includes a Sitara-based main controller and DSP-based cell controllers, requiring reliable inter‑controller communication, synchronization, firmware lifecycle management, and robust fault diagnostics.

The role focuses on developing and integrating embedded software across these platforms, with particular emphasis on TI‑RTOS for DSP development. The operating system for the Sitara‑based main controller has not yet been finalized and may be based on a suitable RTOS or embedded Linux.

This position is ideal for an engineer who combines strong low-level programming skills with practical hardware debugging experience and an understanding of real‑time, safety‑critical or high‑reliability embedded systems.

Job responsibilities

Key Responsibilities

Embedded Firmware and Real‑Time Systems

• Develop and maintain real‑time embedded firmware in C/C++ for Texas Instruments Sitara processors and TMS320F28388D DSPs.
• Develop DSP firmware using TI‑RTOS, including task scheduling, interrupt handling, timing management, and resource coordination.
• Contribute to the software architecture and operating system selection for the Sitara‑based main controller, potentially involving embedded Linux.
• Design and implement multi‑controller synchronization and communication between the main controller and DSP‑based cell controllers.

Bootloader and Firmware Updates

• Design and implement bootloader functionality, including firmware integrity verification and reliable startup behavior.
• Develop firmware update managers for the main and cell controllers, including compatibility checks, failure notification, automatic fallback, and rollback mechanisms.
• Evaluate and implement firmware transfer mechanisms, including EtherCAT-based approaches where applicable.

Parameter Management and Diagnostics

• Design and implement a parameter management framework supporting parameter creation, deletion, naming, data types, derived parameters, default values, and non‑volatile storage.
• Implement parameter change logging, update mechanisms, access controls, authorization hierarchies, write restrictions, synchronization, and validation.
• Develop transient fault recording functionality to capture selected variables before, during, and after fault events.
• Implement timestamping, fault‑record storage, and data retrieval mechanisms while accounting for communication bandwidth and synchronization constraints.

Hardware Integration, Debugging, and Verification

• Integrate firmware with gate drivers, sensors, protection circuits, communication interfaces, and supervisory control systems.
• Debug and verify embedded software using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and hardware‑in‑the‑loop (HIL) test systems.
• Collaborate closely with hardware, control, systems, and test engineers to investigate and resolve integration issues.

Documentation and Software Quality

• Prepare and maintain software requirements, architecture descriptions, interface specifications, test procedures, and release notes.
• Participate in code reviews, configuration management, software verification, and continuous improvement activities.

Required Qualifications

• Strong professional experience in embedded software development using C and/or C++.
• Hands‑on experience with Texas Instruments Sitara processors and/or TMS320F28388D DSPs, with a strong preference for candidates familiar with both platforms.
• Practical experience with low‑level programming, processor peripherals, interrupts, memory management, and hardware interfaces.
• Experience developing real‑time embedded firmware with an understanding of scheduling, timing constraints, and concurrency.
• Experience with TI‑RTOS, particularl
