About the Role We are seeking a seasoned Principal Architect Firmware/Software with 10+ years of expereince to lead the design, development, and optimization of firmware/software for our industrial automation product line, including Distributed Control Systems (DCS), Software Defined Automation, and field I/O devices. You will architect scalable, real-time firmware/software solutions that ensure high reliability, safety, and performance in harsh industrial environments such as manufacturing, oil & gas, LNG, petrochemical, and power generation.

The role also collaborates closely with multiple teams, including offer and program managers, to review and interpret system requirements, translating them into implementable product architectures and specifications for Agile teams. What will you do:

Key Responsibilities Architect end-to-end firmware solutions for DCS controllers, field I/O modules, and gateways with an emphasis on real-time operation, deterministic performance, and deep understanding of external components and their integration into system architecture. Define firmware architecture including RTOS selection, driver development, and communication protocols (e.g., Modbus, Profibus, Foundation Fieldbus), with strong awareness of how external components and systems integrate with DCS development.

Lead design reviews and ensure alignment with key industrial standards such as IEC 62443, IEC 61131, IEC 61499, and other applicable standards influencing cybersecurity, system design, and interoperability. Oversee firmware development in C/C++ with focus on modularity, scalability, and integration with cloud and edge analytics. Provide architectural guidance rather than hands-on coding when appropriate. Lead or oversee troubleshooting of complex issues, unit/integration testing, and ensure conformance with security and communication protocol standards.

Mentor engineers and drive innovation in areas including AI-accelerated architecture, design, implementation, and test workflows. Mandatory Skills (Required) 10+ years in embedded firmware development for industrial automation, with proven experience in DCS, PLC, and I/O systems.

Strong knowledge of ARM Cortex-M/A architectures, microcontrollers, and peripherals (ADC/DAC, PWM, industrial Ethernet, CAN).

Experience with industrial protocols (Modbus TCP/RTU, OPC UA) and real-time embedded systems. Solid understanding of cybersecurity frameworks (IEC 62443), industrial automation standards (IEC 61131, IEC 61499), and embedded testing methodologies. Experience in product architecture or product ownership and leading Agile development teams. Nice-to-Have Skills (Preferred) Technical

Skills:

Experience with Linux kernel development for industrial systems. Familiarity with TSN, edge AI/ML frameworks, and open-source development. Background in high-availability systems, redundancy protocols (PRP/HSR), or FPGA-based acceleration. Proven ability to create modular, future-proof architectures with emphasis on scalability using open-source or inner-source methodologies. Strong experience applying software design patterns such as HAL abstraction, state machines, and layered architecture. Stakeholder Management & Leadership:
Strong interpersonal skills to align cross-functional teams, including hardware, Firmware, Software, Quality, and product management. Experience…
