• Develop and support on-device services and HTTP APIs that enable configuration and control through mobile and desktop applications.

• Implement and maintain networking protocols, including TCP/IP, UDP, HTTP(S), TLS, and service discovery.
• Integrate software with hardware interfaces such as UART, I2C, and SPI.

• Develop and maintain multi-process software architectures, including inter-process communication through messaging systems, Unix sockets, and WebSockets.
• Build and release firmware for multiple product lines, including packaging, OTA update feeds, and signed upgrades.

• Maintain build and CI infrastructure, including GitLab runners, Docker build images, and AWS resources.
• Diagnose and resolve complex Linux system issues related to processes, networking, memory management, and performance.

• Troubleshoot technical challenges across hardware, firmware, operating systems, and application software.
• Identify opportunities to improve software reliability, performance, scalability, and maintainability.

• Collaborate with cross-functional teams to support product development, integration, testing, and issue resolution.
• Participate in software development best practices, including version control, code reviews, automated builds, and CI/CD processes.

• Integrate streaming music services into the platform, including their cloud APIs, authentication flows, and content protection.
