Firmware Engineer

Job Description

The candidate will be responsible for the design and development of firmware components for conferencing products. The firmware will consist of a mixture of embedded software applications and low-level board support package components. The embedded software applications may include, for example, state machines, interrupt service routines, and inter-process communication protocols. The low-level board support components may include components such as boot loaders, Inter-IC communication (I2C) drivers, and UART drivers. This work will be done on proprietary hardware platforms and requires knowledge of real-time deterministic firmware development methodologies and tools. The run-time environment will be an embedded Linux real-time operating system. The firmware developed by the selected candidate must interface to new and existing hardware, firmware, and software. The selected candidate must be able to work effectively in a multidisciplinary engineering team.

Required Education and Experience

• BSEE/BSCS or equivalent with 5-10 years of design and development experience with embedded Linux.
• 5 years of experience writing firmware in C/C++ in a product development environment.
• Experience using tools like emulators, debuggers, oscilloscopes, logic analyzers, and protocol analyzers to locate and resolve firmware-hardware interaction issues.
• Experience using source control tools such as GIT, Microsoft Visual Source Safe, Clear Case, CVS, or Subversion.
• Experience with multitasking, deterministic, real-time firmware architecture development.
• Strong communication, documentation, organizational, and teamwork skills.
• Demonstrated ability to work in a high pressure, small, fast-paced team to meet challenging project deadlines.

Desired Skills, Knowledge, and Experience

• Experience with scripting languages in a Linux OS based development environment.
• Experience modifying Linux board support packages.
• Experience using, developing, and modifying build scripts.
• Experience writing embedded Linux kernel-level device drivers for any of the following: I2C, SPI, RS232, and USB.
• Experience using Linux BusyBox utilities.
• Experience with embedded Linux inter-process communication and synchronization using: message queues, pipes, semaphores, mutexes, etc.
• General knowledge of network communications protocols like TCP/IP, UDP.
• State machine design experience.
• Board-level design and diagnostic experience.
• Experience with static and dynamic code analysis tools.
• Experience with fault tracking analysis.
• Web Server deployment and interfacing to Web Servers.
