Specialist- Linux Architect

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.
