Senior Software Engineer

5V Video; Philadelphia (Philadelphia County); On-site; USD 120,000 - 150,000; Full time

Job summary

5V Video is seeking a senior embedded C/C++ engineer to integrate and optimize graphics and video pipelines for WPE on multiple platforms. You’ll diagnose startup and runtime bottlenecks in high-traffic streaming apps and coordinate with chipset vendors for silicon bring-up.

You will contribute to open-source communities, port WPE to new platforms, and mentor junior engineers while collaborating with QA and release teams.

Qualifications

• 6+ years of C/C++ development experience with memory management, multithreading and profiling.
• Experience with embedded Linux, cross-compilation, Yocto/OpenEmbedded, and constrained hardware debugging.
• Knowledge of graphics/display tech: Wayland, X11, EGL, OpenGL ES, Cairo or Skia.
• Familiar with media pipelines (GStreamer preferred) and adaptive streaming standards (DASH, HLS, MSE/EME).
• Comfort contributing to open-source codebases and upstream communities.

Responsibilities

• Integrate and tune graphics and video pipelines for WPE.
• Diagnose and resolve performance issues on high-traffic streaming apps.
• Port and validate WPE across new silicon with chipset vendors.
• Work upstream with WebKit/WPE community, submitting patches.
• Collaborate with core video engineering, QA, and partners to triage field issues.
• Contribute to technical documentation and mentor embedded engineers.

Job description

What You\'ll Do

• Integrate and tune the graphics pipeline (Wayland compositor, EGL, Cairo/Skia) and video pipeline (GStreamer, hardware-accelerated decode, Media Source Extensions for DASH streaming) that WPE depends on
• Diagnose and resolve performance issues (startup time, frame rate, memory leaks, JS heap growth) surfaced by high-traffic streaming apps running on top of WPE
• Port and validate WPE across new silicon (SoC) platforms in partnership with chipset vendors, and support RDK\'s multi-vendor build and CI process
• Work upstream with the WebKit/WPE open-source community, submitting patches and tracking upstream releases for integration into RDK
• Collaborate with RDKM\'s core video engineering, QA, and release teams, plus external operator and OEM engineering partners, to triage field issues and drive fixes into RDK releases
• Contribute to technical documentation and mentor engineers newer to embedded

What You\'ll Need

• 6+ years of C/C++ development experience, with strong fundamentals in memory management, multithreading, and performance profiling
• Experience with embedded Linux development, including cross-compilation, Yocto/OpenEmbedded, and debugging on constrained hardware
• Working knowledge of graphics/display technologies such as Wayland, X11, EGL, OpenGL ES, Cairo, or Skia
• Familiarity with media pipelines (GStreamer preferred) and adaptive streaming standards (DASH, HLS, MSE/EME)
• Comfort working in and contributing to open-source codebases and upstream communities

Nice to Have

• Direct experience with RDK, RDK-V, or set-top box/CE platform development
• Experience with DRM/CAS integration or Secure Video Path implementations
• Familiarity with Firebolt or other RDK application frameworks
• Experience working with silicon vendors (Broadcom, Amlogic, Realtek, etc.) on platform bring-up
• Contributions to the WebKit or WPEWebKit open-source projects
• Professional Scrum Master / Agile delivery experience in a cross-functional engineering org
