Job summary

Crystal Equation Corporation is seeking an Embedded Software Engineer III to join onsite in Redmond, WA. You will modify firmware and develop test infrastructures for perceptual quality across AR/VR pipelines, spanning from low-level drivers to application-level tools.

This contingent role requires 5+ years in embedded firmware and C/C++, experience with RTOS, Python scripting, and CI/CD workflows, plus strong debugging across hardware/software stacks.

Qualifications

• 5+ years of industry experience developing and testing low-level firmware or systems software for embedded platforms.
• 5+ years of solid programming skills in C and C++, with experience writing production firmware and test applications.
• Experience with the full software development lifecycle: requirements gathering, design, implementation, testing, and delivery.

Responsibilities

• Develop and modify device firmware (C/C++) to support visual 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.
• 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.
• Create clean, well-documented, and testable code; contribute to CI/CD build scripts and automation pipelines as needed.
• Document designs, tradeoffs, test methodologies, and results for cross-functional stakeholders.
