Senior Embedded Software Engineer

About the role

We are seeking a Senior Embedded Software Engineer to sustain, troubleshoot, and improve embedded software for in-service business-jet cabin systems (IFE/CMS). You will work across Linux, QNX, RTOS, and bare-metal environments, diagnose field issues on custom hardware, and maintain certification-ready software deployed in production aircraft. This role owns the health of fielded product lines resolving defects, preventing regressions, and managing component obsolescence — and collaborates closely with hardware, FPGA, systems, quality, and field support teams.

Key Details

• Work Days and Hours: Monday to Friday, Full- Time.

• Location: This is a full-time onsite position located in Kirkland, Washington.

• Work Eligibility: Must possess unrestricted authorization to work in the United States without employer sponsorship.

What you'll do

• Own the software lifecycle of fielded embedded products, driving reliability, maintainability, and continued compliance across microprocessor and DSP-based systems.

• Diagnose and resolve field-reported defects across custom SoC platforms (ARM), peripherals (I2C/SPI/UART, GPIO, USB, Ethernet), and networking stacks (TCP/UDP, multicast).

• Perform root cause analysis on production issues; develop and validate corrective actions through the full verification cycle.

• Lead HW/SW troubleshooting on fielded units using oscilloscopes, logic analyzers, JTAG, and trace tools.

• Lead sustaining engineering efforts on assigned product lines; mentor junior engineers, prioritize defect backlogs, and coordinate with product management on release planning.

• Manage component obsolescence and end-of-life transitions; evaluate, qualify, and integrate alternate parts with minimal design disruption.

• Maintain certification-aligned software processes (requirements, design, code reviews, regression tests, verification evidence) for updates to fielded products.

• Collaborate across FPGA, hardware, manufacturing, quality, and field support teams to resolve cross-functional issues and drive continuous improvement.

Required Qualifications

• Bachelor of Science degree in Computer Science or Electrical Engineering (BSCS, BSEE) or equivalent.

• Eight (8) or more years of embedded software design experience.

• Experience with QNX Neutrino RTOS, including BSP development, driver work, or system integration.

• Must be familiar/experienced with the C programming language in Embedded Systems/Real-Time OS.

• Strong debugging and root cause analysis skills across hardware/software boundaries in production environments.

• Experience sustaining or supporting Ethernet and microprocessor/DSP-based products through their full lifecycle, including post-release maintenance and field issue resolution.

• Logical thought processes, excellent attention to detail, ability to conceptualize, implement, and document innovative solutions.

• Ability to read and understand schematics and datasheets.

• Strong problem-solving skills with a bias toward practical, low-risk fixes that preserve system stability.

• Take ownership, communicate risks early, deliver to commitments.

• Drive technical direction on sustaining priorities and continuous improvement within the team.

• Effectively communicate technical concepts to cross-functional stakeholders and leadership.

• Disciplined approach to regression testing, requirements traceability, and change-impact analysis.

• Proficiency with Git or equivalent source control.

• Ability to quickly ramp up on legacy codebases and make safe, well-scoped changes with minimal regression risk.

Preferred Qualifications

• Experience with diagnostic and test equipment (oscilloscopes, logic analyzers, spectrum analyzers, boundary scan, etc.).

• Experience with HTML/CSS/JS and/or Front-End GUI Design.

• Experience with one or more Real-Time Operating Systems.

• Experience with ARM assembly language.

• Experience with Linux OS tools, Bash scripts.

• Familiarity with DO-178C.

• Familiarity with FAA and/or Mil Spec requirements
