Embedded C++ Linux Developer

Job Summary/Overview:

• Design, develop, test, and debug embedded software applications for Linux-based systems.
• Work on the full software development lifecycle for various embedded devices and hardware platforms.
• Collaborate with cross-functional teams (hardware, QA, product management) to deliver integrated solutions.
• Ensure the reliability, performance, and scalability of embedded software.

Key Responsibilities:

Software Development:

• Design, develop, and maintain embedded software in C++ (often C++11/14/17 or newer) for Linux-based embedded systems.
• Write efficient, robust, and optimized code for resource-constrained environments.
• Implement and optimize low-level drivers, communication protocols (e.g., I2C, SPI, UART, CAN, Ethernet, USB), and system software.
• Work on user-space applications, daemons, and shared libraries.
• Develop firmware for various hardware platforms, including microcontrollers, microprocessors, and SoCs (System-on-Chips).

Linux Specifics:

• Strong experience with Linux operating systems, including kernel and device driver development.
• Hands-on experience with building, configuring, and customizing the Linux kernel.
• Familiarity with Linux OS internals, memory management, inter-process communication (IPC), and thread programming.
• Experience with tools like the Yocto Project (for building custom Linux distributions), BusyBox, Buildroot, etc.
• Knowledge of device trees and hardware abstraction layers.
• Experience with command-line tools and scripting (Bash).

Debugging and Testing:

• Perform system-level debugging and troubleshooting on target hardware platforms.
• Utilize debugging tools such as GDB, JTAG, oscilloscopes, logic analyzers, and hardware-in-the-loop (HIL) testing.
• Conduct unit testing, integration testing, and system validation.
• Participate in code reviews to ensure code quality, maintainability, and adherence to coding standards (e.g., MISRA for safety-critical systems).

Architecture and Design:

• Contribute to system-level design decisions and participate in requirement analysis, architecture definition, and software implementation.
• Apply object-oriented analysis and design (OOAD) principles and software design patterns.
• Optimize software for performance, including memory usage, processing speed, and energy efficiency

Collaboration and Documentation:

• Collaborate with hardware engineers to ensure seamless integration of software and hardware components.
• Work effectively in Agile/Scrum teams.
• Create and maintain technical documentation for software design, code, and test procedures.

Problem-Solving:

• Strong analytical and problem-solving skills to diagnose and resolve complex technical issues.
• Ability to work independently and collaboratively

Required Skills and Qualifications:

• Education: Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
• Experience: Typically 3+ years for a developer role or 3+ years for a senior role.

Technical Skills:

• Strong Proficiency in C++ (modern C++ standards preferred).
• Strong understanding of embedded systems concepts, including real-time constraints, memory management, and hardware-software interaction.
• Hands-on experience with Embedded Linux, including kernel, device drivers, and user-space application development.
• Experience with multithreading and synchronization.
• Familiarity with communication protocols (I2C, SPI, UART, CAN, Ethernet, USB, etc.).
• Experience with version control systems (Git is common).
• Experience with build systems (CMake, Make).
• Knowledge of RTOS (Real-Time Operating Systems) concepts (even if primary focus is Linux).
• Knowledge of GRPC protocol and docker containers

Soft Skills:

• Excellent problem-solving and debugging skills.
• Strong verbal and written communication skills.
• Ability to work independently and as part of a team.
• Quick learner, self-starter, and results-oriented.

Nice-to-Have Skills (Preferred/Good to Have):

• Experience with specific processor architectures (ARM, PowerPC, x86).
• Knowledge of specific industries (Automotive - ISO 26262, Industrial Automation, IoT, Medical Devices).
• Experience with CI/CD pipelines and automated testing frameworks.
• Familiarity with virtualization technologies (Docker) in embedded contexts.
• Experience with scripting languages like Python for automation or testing.
• Contributions to open-source projects related to embedded systems or Linux.
• Experience with specific network protocols (TCP/IP, HTTP, REST, WebSockets).

Work Environment (often mentioned):

• Agile/Scrum methodology
• Collaborative team environment
• Work from office
