Position Description: 

The Embedded Linux person will lead the end-to-end design, development, and optimization of our embedded Linux platform built on Yocto/OpenEmbedded. This role is deeply technical and strategic, responsible for OS architecture, BSP integration, system bring-up, security hardening, and fleet-scale deployment.

You will collaborate cross-functionally with hardware, cloud, DevOps, and application teams to deliver secure, high-performance, and scalable embedded systems used in production at global scale.

Position Location: Gurugram / Jaipur

Reports To:  Engineering Manager

What We’re Looking For:

• BTech, B.S. or M.S. in Computer Science, Electrical Engineering, or a related field.

• 8+ years of experience in Embedded Linux development. Mastery of C and C++ is required, with a deep understanding of object-oriented design and concurrency.

• Proven track record of managing complex, multi-layer Yocto environments and upstreaming contributions to the OpenEmbedded community.

• In-depth knowledge of Linux system internals, memory management, and process scheduling

• Experience with ARMv8/Cortex-A (e.g., MediaTek AIoT Yocto SDK and x86_64 architectures). Ability to debug at the register level using oscilloscopes and logic analyzers.

• Deep expertise in Linux networking stacks (NetworkManager), storage (UBI/UBIFS, Ext4), and low-level IPC (D-Bus, Shared Memory).

• Integrate and customize Linux kernel drivers for peripherals such as I2C, SPI, UART, and USB.

• Exposure to cloud-based fleet management and monitoring systems.

• Expert Git workflow management, Python/Bash automation, and familiarity with Docker/K8s for embedded edge computing.

• A self-starter who thrives in agile environments and acts with a sense of urgency to deliver outcomes.

Unleash your potential: What you will be doing and owning:

• Define and lead the long-term OS architecture strategy using Yocto/OpenEmbedded. Evaluate and select SoC vendors, BSPs, and core system components (init systems, connectivity stacks, and filesystems).

• Configure, optimize, and patch Linux kernels for performance and security. Manage U-Boot/Coreboot and write complex Device Trees for custom hardware.

• Architect end-to-end security solutions, including Secure Boot, Full Disk Encryption (FDE), and TPM/TEE integration. Conduct vulnerability assessments and manage the lifecycle of CVE remediation.

• Design and maintain robust CI/CD pipelines for automated image builds. Implement fail-safe A/B Over-the-Air (OTA) update mechanisms (e.g., Mender, RAUC, SWUpdate) and remote monitoring telemetry.

• Debug "impossible" problems using JTAG, GDB, ftrace, and perf. Drive optimizations for ultra-fast boot times, minimal memory footprints, and extreme power efficiency.

• Develop and manage BitBake recipes, custom layers, and configuration files to ensure reproducible builds.

• Integrate hardware drivers, device trees, and Board Support Packages (BSPs) into Yocto-based images.

• Lead hardware bring-up and debug complex issues across the bootloader, kernel, and user space using JTAG, serial consoles, and GDB.

• Fine-tune system performance, including boot time optimization, memory footprint reduction, and power efficiency.

• Support automated image builds and testing by integrating build systems with Jenkins or GitHub Actions.

• Act as a technical mentor to junior engineers. Collaborate with hardware teams on schematic reviews and with application teams to provide high-performance SDKs and containerized environments.
