About the Role

Job Title: LDD (Low-Level Development) Kernel Engineer

Domain: Embedded Systems, Low-Level Software Development, Linux Kernel, Device Drivers

Working Model: Work from Office (WFO) – 5 days a week

Role Type: Permanent

Overall Experience Range: 3–8 years

Expected Notice Period: Immediate joiners to 30 days preferred

Role Overview

We are looking for Low-Level Development (LDD) Engineers with strong C/C++ programming skills and experience in embedded software development. Candidates may have expertise in Linux kernel and device drivers, embedded Linux or Zephyr/Ethernet development, or C++-based embedded systems and SoC-level software.

The role involves developing and debugging low-level software, troubleshooting system-level issues, and delivering reliable, production-quality code. Candidates should have strong analytical skills and be comfortable working with embedded platforms and hardware-software interfaces.

Key Responsibilities

• Develop, debug, and maintain low-level software using C and C++.

• Work on embedded software, Linux-based development, kernel components, device drivers, or equivalent low-level systems.

• Troubleshoot software issues across operating system, embedded platform, and hardware-software interfaces.

• Support system-level debugging, Linux builds, and embedded platform development.

• Collaborate with hardware, platform, and software engineering teams.

• Write maintainable, reliable, production-quality code.

• Use scripting and automation tools where required.

• Take ownership of assigned development tasks and deliver solutions within agreed timelines.

Required Skills & Experience

• Strong C/C++ programming fundamentals.

• Experience in embedded systems or low-level software development.

• Knowledge of Linux-based development or operating system fundamentals.

• Strong analytical, debugging, and problem-solving skills.

• Ability to work independently and collaborate with cross-functional teams.

• Good communication and task-management skills.

Three Skill Profiles:

Skill 1: LDD / Zephyr (Ethernet) – E1

Experience: 2+ years

Required / Relevant Skills

• C and C++ programming.

• Embedded systems and low-level software development.

• Device drivers or equivalent embedded software.

• Exposure to embedded Linux, Zephyr RTOS, or wired Ethernet applications and drivers.

• Python scripting.

• Embedded software fundamentals and debugging.

Preferred Skills

• Low-level boot processes.

• Serial communication and peripheral development.

• Hardware-level debugging and troubleshooting.

Role Focus: Embedded software development, Ethernet, Zephyr, device drivers, and low-level system components.

Skill 2: LDD Developer – C++ Embedded (E3)

Experience: 5+ years

Required / Relevant Skills

• Strong C and modern C++ programming.

• Linux-based development and embedded systems exposure.

• Algorithms and data structures.

• Rule engines, constraint systems, or complex state-driven software.

• Computer architecture and system-level concepts.

• Ability to independently own features and debug complex systems.

Preferred Skills

• SoC fundamentals, including boot flow, pin multiplexing, GPIO, and clock trees.

• Hardware bring-up and debugging.

• IP-XACT, register maps, or hardware-adjacent tooling/EDA.

• Python/Tcl scripting and code generation.

• Power-management concepts.

Role Focus: C++ embedded development, rule-driven systems, system-level software, and hardware-adjacent development.

Skill 3: LDD Developer – Linux Kernel / Device Drivers (E2)

Experience: 2–3 years

Required / Relevant Skills

• Strong C/C++ programming.

• Linux kernel debugging.

• Linux kernel and device-driver model.

• ARM architecture.

• Linux builds and device-driver development.

• Strong analytical and troubleshooting skills.

Preferred Skills

• JTAG debugging.

• Oscilloscope familiarity.

• Embedded hardware-software debugging.

Role Focus: Linux kernel, device drivers, ARM architecture, and low-level system debugging.

Desirable Skills & Experience

Depending on the subprofile, candidates may have experience with:

• Embedded Linux or Zephyr RTOS.

• Wired Ethernet applications or drivers.

• Linux kernel and device-driver development.

• ARM architecture and SoC fundamentals.

• Hardware bring-up and debugging tools.

• Python/Tcl automation and code generation.

• Register maps, IP-XACT, and hardware-adjacent tooling.

Conclusion – Ideal Candidate Profile

The ideal candidate is a hands-on LDD/embedded software engineer with strong C/C++ skills, solid debugging capabilities, and experience in one or more relevant low-level development areas. Candidates should be screened against the specific skill profile required by the team: embedded/Zephyr/Ethernet, C++ embedded and SoC systems, or Linux kernel and device drivers.

Additional Requirements

• Education: BE/B.Tech/ME/M.Tech in a relevant engineering discipline, preferably ECE, EE, or CS. Civil, Mechanical, and Biotechnology backgrounds are not preferred.

• Location: Hyderabad.

• Work Arrangement: Work from Office only, 5 days a week.

• Notice Period: 0–30 days preferred.

Note: This is one LDD hiring requirement with three skill-based subprofiles. Shortlist candidates against the relevant split rather than expecting every candidate to possess all listed skills.
