About Philo, Inc.

At Philo, we are a collective of innovators and product specialists dedicated to revolutionizing the television landscape. Our mission is to integrate cutting-edge technology with the captivating medium of television, creating an unparalleled viewing experience. We leverage cloud technology, modern software stacks, machine learning, and bespoke native applications across all platforms to deliver a seamless streaming experience.

Position Overview: Senior Video Player Software Engineer

Our video streaming framework is intricately designed, highly scalable, and utilizes cloud capabilities to manage a significant portion of North American internet traffic. We develop our video players in-house, utilizing a shared codebase across various platforms and incorporating open-source technologies for playback. Our proprietary video pipeline efficiently processes both live and on-demand content, dynamically integrates advertisements through Server-Side Ad Insertion (SSAI), and delivers them to our expanding audience at an exabyte scale. We employ top-tier commercial and open-source tools during the transcoding phase, coupled with just-in-time packaging and our unique ad stitching technology that generates tailored manifests for each user session.

We are on the lookout for a passionate Video Software Engineer to enhance and refine our playback architecture. As part of a compact team, you will engage in experimentation and innovative problem-solving to elevate the playback experience and its impact on our business. You will have the autonomy to explore various technologies and delve deep into the system. Whether it involves debugging in Chromium, contributing to open-source initiatives like Shaka Player, or devising inventive methods to enhance our players, your contributions will drive significant improvements.

Key Responsibilities:
  • Oversee the application-driven playback quality across all devices utilizing Philo content.
  • Design, implement, deploy, and monitor the next generation of Philo's content streaming frontend infrastructure.
  • Facilitate ongoing enhancements to the reliability, performance, latency, and security of Philo's streaming platforms, utilizing both proprietary technology and, when necessary, contributing to open-source projects.
  • Ensure comprehensive measurement and optimization of every facet of our content delivery process and the quality of the user viewing experience (QoE).
Qualifications:
  • 8+ years of experience in software development.
  • Proficient in integrating video players, including but not limited to Shaka, media3/Exoplayer, and AVPlayer.
  • Familiarity with streaming protocols such as MPEG-DASH, HLS, MPEG TS, fMP4, CMAF, Zixi, and SRT.
  • Knowledgeable in CDN configuration, video stream transcoding and packaging, and DRM processes, with the ability to independently troubleshoot and enhance overall system performance.
  • Understanding of Server-Side Ad Insertion (SSAI).
  • Demonstrated success in developing highly efficient and feature-rich web, Android, and/or iOS applications using JavaScript/TypeScript, Kotlin, or Swift.
  • Willingness to learn new technologies and programming languages to meet application needs related to playback and telemetry.
  • Experience handling large datasets to prioritize projects, assess impact, and navigate complex problem spaces.
  • Adept at recognizing when a problem necessitates a backend solution and effectively communicating requirements to backend engineers.

Preferred Qualifications:

  • Active contributor to significant open-source video streaming projects (e.g., Shaka, Bento, ffmpeg/libav, media3/Exoplayer).

Employment Status: Full-time
Compensation: Competitive salary range based on experience, along with stock options and comprehensive health benefits.

We are committed to fostering a diverse and inclusive workplace, welcoming individuals from various backgrounds, experiences, skills, and perspectives. Philo is an equal opportunity employer, believing that everyone performs best when supported by their colleagues and the organization. We offer a generous benefits package to ensure the well-being of our team.
