Job summary

Ascendion in Redmond, WA is seeking an Embedded Software Engineer III to advance perceptual quality software for AR/VR devices. You will modify firmware, build test infra, write automated and manual tests, and collaborate with teams to ensure high-quality display pipelines.

The role spans from low-level firmware to tooling, requiring strong systems thinking, C/C++, RTOS experience, and a quality-first mindset. Onsite employment with competitive salary and benefits.

Qualifications

• 6+ years in firmware or systems software for embedded platforms.
• Strong C/C++ production firmware and test applications.
• Experience with RTOS and real-time multi-threaded apps.
• Experience building reusable test frameworks or harnesses.

Responsibilities

• Develop and modify device firmware (C/C++) to support perceptual quality features across computer vision, graphics, and display pipelines.
• Design, implement, and maintain test infrastructure for evaluating perceptual quality metrics (e.g., latency, quality/accuracy, motion-to-photon).
• Write new tests and maintain existing tests including unit tests, integration tests, manual validation procedures, and CI automation.
• Debug issues across the full software stack—from hardware bring-up and driver-level defects through application-layer rendering, providing both quick workarounds for time-critical issues and long-term solutions.
• Develop optimized firmware and software utilities targeting embedded environments, with portability across processors and platforms.
• Collaborate with internal teams to improve and tailor existing firmware, device drivers, and applications to project requirements.
