Specialist- Linux Architect

What you'll do:

• Own the embedded Linux platform strategy (Yocto/Buildroot) across multiple SoC families (e.g., NXP i.MX, TI Sitara, STM32MP1, Renesas RZ), targeting real-time, ruggedized, and low-power designs.
• Define kernel config, PREEMPT_RT strategy, boot chain (U-Boot, secure boot, A/B), systemd, filesystem layouts, partitioning, and recovery for high-availability products (fire panels, emergency lighting).
• Establish platform abstraction layers for reusable services: logging/telemetry, time sync/IEEE 1588 PTP, diagnostics, device management, and firmware update.
• Architect and review BSP/device drivers (I2C, SPI, UART, GPIO, CAN/CAN-FD, USB, PCIe, Ethernet, LTE/5G modems, Wi-Fi/Bluetooth), DRM/KMS, and HMI graphics stack.
• Lead performance/latency tuning (irqbalance, CPU affinity, cgroups, scheduling), power management (PM QoS, cpufreq), and file system health for field durability.
• Guide protocol stacks: Profinet, Siemens S7, OPC UA, Modbus/TCP, EtherNet/IP, BACnet, EtherCAT (as applicable), MQTT/CoAP, OCPP 1.6/2.0.1 for connectivity cards.
• Ensure determinism/time sync (PTP/NTP/TSN considerations) for PLC/HMI workloads.
• Design and govern EdgeX Foundry deployments: device services (Go/C SDKs), profiles, app services, message bus, secret store, and interop with industrial southbound and Azure northbound.
• Architect Azure IoT integration: IoT Hub/IoT Edge, DPS (X.509), Device Twins, module composition, offline buffering, and certificate-based provisioning at scale.
• Define a defense-in-depth strategy: secure boot, TPM/HSM, mTLS, cert lifecycle/rotation, FDE, nftables, AppArmor/SELinux, vulnerability management (CVE/SBOM).
• Align with IEC 62443 (industrial cybersecurity) and relevant functional safety/industry standards (e.g., EN 54 for fire panels, IEC 61508 for SIL, DALI-2/IEC 62386 for emergency lighting, IEC 60598-2-22, relevant EMC/RF/CE requirements).

• B.E./B.Tech/M.E./M.Tech in ECE/EE/CS (or equivalent).
• 18+ years in embedded Linux with 8+ years as Architect/Principal/Tech Lead.
• Proven delivery of safety-critical or industrial products at scale.

• Bachelor's Degree in Computer Science/Electrical/Electronics Engineering from an accredited institution required.
• 19+ years of hands-on expertise in C, C++, embedded OS based firmware applications on microcontrollers, device drivers, data structures.
• Experience with Linux applications is a must
• Industrial Ethernet protocols like EtherNet/IP, Modbus TCP, Profinet, BACnet IP, 61850 and or device level field bus technologies -Modbus, Device Net, Profibus DP, BACNet, REST is preferred. Good knowledge on Linux (Driver, Kernel) , API based framrworks or SDK.
• 10+ years of hands-on expertise in C, C++, RTOS based firmware applications on microcontrollers
• Experience with working on developing Linux applications for embedded systems is a must
• Experience with Yocto and understanding of the Bitbake concepts, CMAKE is an added advantegate
• Experience in development of industrial fieldbus communication protocols like EtherNet/IP, Modbus TCP, Webserver.
• Experience in RTOS platform, address Cyber-security requirements, fix the issues reported by static code anaysis tools like Coverity or parasoft.
• Hands-on experience in developing application firmware for user interfaces & writing Unit Tests.
• Experience in working in Agile Team & usage of tools like JIRA, BitBucket, JAMA.
• Hands-on experience on developing test automations will be added advantage.
• Excellent interpersonal and communication skills, particularly with respect to written and oral communication, including the ability to explain technical concepts.
• Sound Knowledge and experience with process frameworks (e.g. CMMI) including requirements management, defect tracking, build management, change management, and configuration management tools
• Experience collaborating with local / global suppliers for Hardware/Software procurement, building test lab setups etc.
• Experience in performing Software FMEA
• Excellent communications skills. A high degree of aptitude, creativity is required.
• Understanding of OPC-UA, MQTT, PROFINET, EtherCAT.
