HEX20; India; On-site; INR 2,500,000 - 4,000,000; Full time

Job summary

HEX20 in India is seeking a Senior Embedded Software Engineer to architect and lead development of real-time and Linux-based embedded systems. You will drive technical decisions across FreeRTOS and embedded Linux platforms and mentor engineers.

The role focuses on setting architecture, coding standards, cross-functional collaboration with hardware teams, and delivering robust, scalable embedded solutions.

Qualifications

• 5–7 years of embedded software engineering experience with system-level ownership.
• Proven architecture experience using FreeRTOS (task design, memory strategy, ISR-to-task communication).
• Deep embedded Linux expertise (kernel config, drivers, BSP customization, Yocto/Buildroot).
• Strong understanding of ARM Cortex-M/A architectures and cross‑platform debugging.
• Experience leading design reviews and mentoring engineers; strong written and verbal communication.

Responsibilities

• Architect embedded software systems spanning FreeRTOS subsystems and embedded Linux platforms.
• Define system architecture, task partitioning, IPC, and overall software design.
• Lead RTOS vs Linux boundary decisions, BSPs, and kernel/driver integration.
• Set coding standards, review processes, and best practices across the team.
• Mentor junior engineers; lead design and code reviews.
• Drive root-cause analysis for complex system-level issues.
• Own technical roadmap decisions with product and hardware teams.
• Evaluate and integrate new SoCs, toolchains, and platform technologies.

Job description

• Looking for a Senior Embedded Software Engineer to architect and lead development of real-time and Linux-based embedded systems.
• You will drive technical decisions across FreeRTOS and embedded Linux platforms, set architecture and coding standards, and mentor engineers across the team.

Key Responsibilities

• Architect embedded software systems spanning FreeRTOS-based subsystems and embedded Linux platforms
• Define system architecture, task/process partitioning, IPC strategy, and overall software design
• Lead technical decisions on RTOS vs. Linux boundaries, board support packages (BSPs), and kernel/driver integration
• Set coding standards, review processes, and best practices across the embedded team
• Guide and mentor junior and mid-level engineers; lead design and code reviews
• Drive root-cause analysis for the most complex system-level and cross-layer issues
• Own technical roadmap decisions in collaboration with product and hardware teams
• Evaluate and integrate new SoCs, toolchains, and platform technologies

Required Skills & Qualifications

• 5-7 years of embedded software engineering experience, including system-level architecture ownership
• Proven experience architecting solutions using FreeRTOS (task/priority design, memory strategy, ISR-to-task communication, scheduling trade-offs)
• Strong hands-on experience with embedded Linux (kernel configuration, device drivers, BSP customization, Yocto/Buildroot)
• Deep understanding of microcontroller/microprocessor architectures (ARM Cortex-M/A or similar)
• Strong grasp of low-level debugging and system bring-up across both RTOS and Linux environments
• Track record of leading design reviews and mentoring engineers
• Excellent communication skills, able to justify architectural trade-offs to cross-functional stakeholders
• Ability to lead, mentor, and do task planning for a group size varying from 3 to max 7 engineers.

Preferred Skills

• Experience with multi-core or heterogeneous SoCs (RTOS + Linux running together)
• Experience with secure boot, firmware signing, or embedded security best practices
• Familiarity with communication buses at scale (Ethernet/TCP-IP stacks, CAN-FD, USB)
• Experience setting up CI/CD pipelines for embedded targets (hardware-in-the-loop testing)
