Embedded Software Engineer

Hi,

Hope you are doing well.

Job Title: Embedded Software Engineer

Location: Palo Alto, California

Duration: Fulltime

Job Description:

Key Responsibilities:

DDS Communication establishment on Embedded Systems

Design and implement

Data Distribution Service (DDS)

communication layers for real-time data exchange between system components. Establish reliable, low-latency, high-throughput data communication between devices, focusing on QNX-based systems running on 8255 PPI hardware. Ensure efficient and scalable communication using

DDS QoS (Quality of Service)

policies for real-time embedded systems. Development on 8255 PPI Hardware

Interface with the

Intel 8255 PPI

to control and communicate with external peripherals, such as I/O devices, ensuring compatibility and efficient data exchange. Develop low-level drivers and HAL to facilitate communication between the processor and the 8255 PPI peripheral device. Perform system bring-up and debugging of 8255 PPI interfaces for embedded software running on the QNX OS. QNX Operating System

Develop, port, and optimize embedded software for the

QNX Real-Time Operating System (RTOS) , ensuring compliance with real-time constraints. Utilize QNX features such as

message passing ,

process scheduling , and

multithreading

to ensure efficient system performance. Implement embedded applications on QNX using

POSIX APIs

and QNX's proprietary communication and inter-process communication (IPC) mechanisms. Hardware Abstraction Layer (HAL) Design

Design and implement

Hardware Abstraction Layers (HAL)

to decouple core application logic from hardware-specific details. Enable portability of the software across different platforms by isolating hardware-specific code in HAL modules. Cross-Platform Development

Use

cross-platform libraries

(e.g.,

Boost ,

Qt , or

SDL ) for essential tasks like file handling, network communication, and graphics rendering to ensure that the system is modular and portable across different platforms. Work with hardware-independent libraries to abstract platform differences, ensuring scalability and ease of future integration. Modular Architecture

Design the system using a

modular software architecture

that breaks the system into independent components, such as communication, computation, and I/O. Implement clean, maintainable, and reusable code by isolating system functionalities into discrete modules, allowing for easy testing and integration. Testing & Debugging

Conduct

unit testing ,

integration testing , and

system-level testing

to validate embedded software components. Utilize debugging tools and techniques for real-time systems on QNX, such as

QNX Momentics IDE ,

gdb , and hardware debuggers, to trace and resolve issues in the 8255 and DDS communication stack. Required Qualifications:

Bachelor's or Master's degree

in Computer Science, Electrical Engineering, or a related field. 5+ years

of experience in embedded software development, particularly with real-time systems and hardware interfacing. Proficiency in programming languages like

C ,

C++ , and

Python

for embedded systems. Strong experience with

QNX RTOS

(message passing, multithreading, memory management, etc.). Experience with

DDS middleware

(e.g.,

RTI Connext DDS ,

OpenDDS ,

Eclipse Cyclone DDS ) for real-time communication in distributed systems. Deep understanding of

Intel 8255 PPI

hardware and peripheral interfacing techniques. Experience in designing and implementing

HAL (Hardware Abstraction Layers)

to separate core logic from hardware-specific details. Familiarity with

cross-platform libraries

such as Qt, Boost, or SDL for network communication, graphics, and file handling. Strong skills in modular software design, with the ability to break down systems into independent, reusable components. Experience in working with communication protocols such as

SPI ,

I2C , and

CAN . Preferred Qualifications:

Familiarity with

real-time communication

protocols and design patterns. Experience working in

automotive, aerospace, or industrial control systems . Knowledge of

hardware debugging tools , emulators, and logic analyzers for low-level driver development. Experience in developing software that interfaces with

DSPs ,

FPGAs , or other co-processors. Familiarity with version control systems like

Git

and continuous integration practices. Soft Skills:

Strong analytical and problem-solving abilities. Ability to work independently and as part of a cross-functional team. Excellent verbal and written communication skills, particularly in documenting complex technical designs. Strong attention to detail and a focus on delivering high-quality, reliable software.
