Senior Middleware Engineer (Linux, C++)

Luxoft; Polska; On-site; PLN 120,000 - 190,000; Full time

Job summary

Luxoft is seeking an experienced Embedded Linux engineer to design middleware and platform services for Linux-based devices. You will optimize IPC, data flow, and resource usage while addressing performance bottlenecks across middleware, OS, and hardware layers.

You will collaborate with firmware, cloud, and application teams to define interfaces and APIs, implement platform-level features, and guide architecture evolution for scalable embedded platforms.

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.
