Job summary

Luxoft Poland seeks a skilled Embedded Linux Engineer to design middleware, platform libraries, and services for embedded Linux platforms. You will optimize IPC, data flow, and system resource usage while addressing performance bottlenecks and ensuring scalable, reliable operation across hardware layers.

You will collaborate with firmware, cloud, and app teams to define APIs, implement secure logging and configuration management, and guide platform evolution with architecture input.

Qualifications

• BS or MS in Computer Science, Electrical Engineering, or a related field.
• Proficiency in C and C++ for embedded and system-level development.
• Strong experience with Linux internals (system services, IPC, device drivers, kernel/user space interactions).
• Solid understanding of embedded system architecture, SoC components, and hardware/software interaction.
• Experience with scripting languages (Bash, Python) for build, automation, and testing.
• Familiarity with common hardware interfaces (I2C, SPI, UART, USB, PCIe).

Responsibilities

• Design and develop middleware components, platform libraries, and system services for embedded Linux platforms.
• Optimize inter-process communication, data flow, and system resource utilization to improve overall performance.
• Analyze and resolve system-level performance bottlenecks, ensuring reliability and scalability of embedded platforms.
• Collaborate with cross-functional teams (firmware, cloud, and application) to define platform interfaces, APIs, and integration points.
• Implement and maintain platform-level features such as logging, security frameworks, and configuration management.
• Debug complex system issues across the middleware, OS, and hardware layers.
• Contribute to architecture discussions and provide technical guidance for platform evolution.

Job description

We utilize a city's existing fleet and connected mobile devices to collect real-time data for traffic enforcement. Our advanced AI-driven, vision-based technology detects and analyzes traffic violations, assisting cities in achieving Vision Zero goals. Our team operates in Poland and San Francisco.

Responsibilities:

• Design and develop middleware components, platform libraries, and system services for embedded Linux platforms.
• Optimize inter-process communication, data flow, and system resource utilization to improve overall performance.
• Analyze and resolve system-level performance bottlenecks, ensuring reliability and scalability of embedded platforms.
• Collaborate with cross-functional teams (firmware, cloud, and application) to define platform interfaces, APIs, and integration points.
• Implement and maintain platform-level features such as logging, security frameworks, and configuration management.
• Debug complex system issues across the middleware, OS, and hardware layers.
• Contribute to architecture discussions and provide technical guidance for platform evolution.

Mandatory Skills Description:

• BS or MS in Computer Science, Electrical Engineering, or a related field.

• Solid understanding of embedded system architecture, SoC components, and hardware/software interaction.
• Experience with scripting languages (Bash, Python) for build, automation, and testing.
• Familiarity with common hardware interfaces (I2C, SPI, UART, USB, PCIe).

Nice-to-Have Skills Description:

• Experience with Linux kernel configuration, building, and debugging.
• Knowledge of ARM-based platforms and low-level hardware bring-up.
• Exposure to middleware frameworks, IPC mechanisms (DBus, gRPC), or platform APIs.
• Experience with OTA update systems for OS, applications, and firmware.
• Understanding of multimedia pipelines, CUDA/OpenCL, or GPU acceleration.
• Familiarity with CAN/CAN-FD or other automotive/industrial protocols.
• Experience with security frameworks (secure boot, encryption, key management) in embedded systems.
