Middleware Dev (NCS/Job/ 3123)

 

Key Responsibilities

• Develop and enhance Linux embedded audio/generic software across user-space

and middleware layers.

• Design, integrate, and debug audio frameworks including PulseAudio and

GStreamer.

• Implement and maintain audio pipelines, routing, and control paths for playback

and capture use cases.

• Work on Linux inter-process communication (IPC) mechanisms including: 

o Sockets

o DBus

o Shared memory and signaling constructs where applicable

• Integrate audio software with hardware and driver layers, ensuring correct

interaction between software and underlying audio hardware.

• Build and customize Linux images using Yocto, including recipe modifications and

audio component integration.

• Debug system-level issues involving software–hardware interaction, timing, latency,

and synchronization.

• Collaborate with cross-functional teams (kernel, BSP, hardware, and system teams)

to deliver stable and optimized audio solutions.

• Perform code reviews, root-cause analysis, and contribute to design and technical

documentation.

• Support performance, stability, and power optimization for audio use cases on

embedded platforms.

Must-Have Skills

• Strong proficiency in C programming, with experience writing efficient and

maintainable code.

• Hands-on experience with Linux Embedded systems.

• Solid understanding of audio concepts (PCM, sampling rates, latency, buffering,

pipelines).

• Practical experience with PulseAudio and/or GStreamer frameworks.

• Experience working with Linux IPC mechanisms: 

• Sockets

• DBus

• Good understanding of software–hardware interaction, including binder-like

abstractions and interface layers between software components and hardware

drivers.

• Experience with Yocto build system and Linux image customization.

• Strong debugging skills across user-space and system-level software.

• Ability to read and understand complex existing codebases.

Desirable Skills

• Exposure to Linux audio subsystems (ALSA, middleware-to-driver interaction).

• Experience in embedded audio driver interaction or audio HAL-like layers.

• Familiarity with multi-process architectures and service-based designs.
