Embedded Firmware & Edge Gateway Development
▪ Lead end-to-end firmware design and development for industrial IoT edge gateways on ESP32, STM32,
and ARM-based platforms, from concept through production release
▪ Architect and implement modular firmware on FreeRTOS and embedded Linux with secure commissioning,
OTA updates, dual-bank rollback, and configurable edge logic orchestration
▪ Implement multi-protocol connectivity including BLE 5.0, Wi-Fi, Ethernet, RS485/Modbus RTU, and
MQTT/TLS cloud integration with network failover and remote device management
▪ Own the full embedded software lifecycle: requirements, architecture, coding, code review, integration
testing, and release management
Industrial Protocols & Real-Time Networking
▪ Design, port, and validate industrial protocol stacks including PROFINET IO Device, OPC UA, HART, and
TSN/PTP (802.1AS) solutions across Linux, FreeRTOS, and Yocto-based platforms
▪ Lead conformance testing with ART/ETS tooling, PLC integration validation, and packet-level debugging for
real-time industrial communication requirements
▪ Build TSN demonstration and validation platforms with PTP synchronization, scheduled traffic,
YANG/sysrepo configuration, NETCONF APIs, and multi-node latency/jitter measurement
Linux Platform Engineering & Device Integration
▪ Perform embedded Linux board bring-up, device tree customization, kernel driver development, and BSP
integration on TI AM64x, AM437x, PHYTEC, and BeagleBone platforms
▪ Develop and maintain Yocto-based build environments, cross-compilation toolchains, and CI-ready
firmware build pipelines with coding standards and static analysis practices
▪ Support hardware-software co-design including schematic review, peripheral integration, factory validation,
and field reliability qualification
Technical Leadership & Customer Engagement
▪ Serve as technical SPOC for global client engagements across pre-sales, SoW definition, effort estimation,
RFP responses, and delivery governance
▪ Lead and mentor cross-functional teams of 15–20 engineers across firmware, test, and systems integration
workstreams
▪ Collaborate with product management, systems engineering, and customer stakeholders; manage
workstreams using project management tools (e.g. Jira, Azure DevOps) with planning, estimation, and risk
management
SKILLS & EXPERIENCE
Essential
▪ 7+ years of hands-on embedded firmware and software development in industrial automation or IoT
environments
▪ Expert-level proficiency in C and C++; strong understanding of RTOS constraints, memory management,
concurrency, and real-time firmware design
▪ Proven experience with FreeRTOS, embedded Linux (Yocto), kernel drivers, device tree, and cross-
compilation for ARM32/aarch64 platforms
▪ Demonstrable delivery of industrial IoT edge gateways with MQTT/TLS, Modbus RTU, BLE, OTA, and
secure device commissioning
▪ Deep experience with industrial communication protocols including PROFINET, OPC UA, HART, TSN/PTP,
and Modbus across UART, SPI, RS485, Ethernet, and USB interfaces
▪ Strong background in firmware integration with hardware, including schematic review, protocol tracing
(Wireshark), and field debugging
▪ Experience with verification and validation methodologies, conformance testing, test frameworks (GTest),
and delivery traceability
▪ Proven track record leading technical delivery as team lead, SME, or customer technical SPOC in multi-site
OEM and enterprise programs
▪ Exposure to industrial technology ecosystems, techno-commercial proposals, and end-to-end product
development processes
Desirable
▪ Familiarity with NETCONF/YANG, sysrepo, and centralized TSN configuration (CUC/CNC) for automated
stream scheduling
▪ Experience with HMI development, touchless network orchestration, and browser-based commissioning
portals
▪ Knowledge of deterministic networking principles, PTP grandmaster/slave synchronization, and TSN traffic
scheduling (802.1Qbv/Qbu)
▪ MBA or post-graduate qualification in data science, analytics, or business management; international client
engagement experience (Japan, US, Europe)
