Senior Embedded Software Engineer – Hardware/Software Integration

Location: Kirkland, WA (On-site with part-time WFH flexibility)

Please, no agency solicitations/submittals. Only direct applicants will be considered

Candidates local to the greater Seattle/Kirkland, WA area are highly desired. Relocation support is not available for this position.

Astronics Advanced Electronic Systems (AES) is seeking a Senior Embedded Software Engineer with strong hardware/software integration experience to join our Cabin Electronics Product Group in Kirkland, WA.

The Cabin Electronics Product Group is the world’s leading manufacturer of in-seat power systems for the commercial airline industry. Our EmPower® product line provides scalable power solutions used by over 280 airlines, IFE suppliers, and all major aircraft OEMs worldwide.

In this role, you will support embedded software for aircraft products currently in production
, with a strong emphasis on:

• HW/SW integration and verification on target hardware
• Root-cause analysis of field and production issues
• Design and implementation of embedded software improvements

You will collaborate closely with Product Support, Electrical, Systems, and Test Engineering to ensure our products meet performance, reliability, and regulatory requirements. This position requires a solid understanding of how embedded software interacts with hardware, and how design decisions affect product quality, manufacturability, and cost.

• Develop, modify, and maintain embedded software for production aircraft power systems (resource-constrained environments).
• Integrate and test software on actual hardware
  : bring-up boards, run diagnostics, and validate functionality using lab equipment.
• Investigate and resolve field and production issues
  , including:
• Reproducing issues on hardware
• Performing root-cause analysis across HW/SW boundaries
• Implementing and verifying corrective actions
• Perform and evaluate software design changes and conduct verification testing associated with design updates.
• Develop software artifacts compliant with RTCA DO-178C processes (Level
  
  D).
• Review and update software requirements, architecture, design documents, and verification test plans/procedures
  .
• Serve as a subject matter expert for specific embedded software components across multiple products.
• Participate in peer reviews with cross-functional teams and key stakeholders.
• Provide accurate task estimates and status updates to support project planning and customer commitments.
• Document root cause analyses, corrective actions, and engineering change justifications for internal and customer‑facing audiences.
• Proactively identify and implement improvements to software development and integration processes
  , leveraging industry best practices.

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science
  , or a related field.

• Typically 5+ years of hands‑on experience developing and troubleshooting embedded software for resource‑constrained systems (e.g., bare metal or RTOS‑based, embedded Linux on SoCs, power electronics controllers, or similar).
• Proven experience with hardware/software integration
  , including:
• Working directly on target hardware (board bring‑up, driver debugging, HW interaction)
• Using lab instruments (oscilloscopes, logic analyzers, protocol analyzers) to debug and characterize system behavior
• Proficiency in C and/or C++ for embedded systems; experience with Python or similar scripting language for test automation or tooling is a plus.
• Experience debugging and optimizing existing codebases in a production or field‑support context.
• Working knowledge of RTCA DO-178C required.
• Familiarity with software configuration management and problem reporting tools (e.g., Star Team, Polarion, or similar).
• Knowledge of communication interfaces/protocols such as UART, RS-485, ARINC 429 is a plus.
• Embedded Linux experience and familiarity with device trees are desired.

• Ability to analyze and resolve complex embedded software and system integration issues with sound technical judgment.
• Strong verbal and written communication skills.
