Job description

At Philo, we’re a group of technology and product people who set out to build the future of television, marrying the best in modern technology with the most compelling medium ever invented — in short, we’re building the TV experience that we’ve always wanted for ourselves. In practice this means leveraging cloud delivery, modern tech stacks, machine learning, and hand-crafted native app experiences on all of our platforms. We aim to deliver a rock solid experience on the streaming basics, while cooking up next generation multi-screen and multi-user playback experiences.

Senior Backend Software Engineer (Video Engineering)

Video is at the core of Philo and what customers engage with the most: watching their favorite shows. The Video Infrastructure team is crucial for delivering on this high expectation, and — together with the Ads team — for generating significant revenue through advertising. We own the systems that get every frame of Philo to every screen: live and video on demand transcoding, DRM and license servers, manifest generation that holds up under peak live events, and Server-Side Ad Insertion (SSAI). We support playback across all major streaming platforms, and partner closely with the Ads, Client, and Data teams to build out the end-to-end video player and ad experience. We increasingly apply machine learning to inspect both content and ads — surfacing quality issues, optimizing encodes, and improving the viewing experience in ways that weren’t possible a few years ago.

Philo's video streaming infrastructure is highly distributed, horizontally scalable, and harnesses the power of cloud computing to deliver video at exabyte scale. Our video pipeline, developed in-house, uses industry-leading commercial and open source components to transcode, package in real-time, and generate HLS and DASH manifests on a per-user, per-session basis. The team also builds and maintains highly available RESTful web services that dynamically scale to meet the ever-increasing demands of simultaneous video streams across our platform.

We are seeking an enthusiastic Senior Software Engineer to help us build and optimize the next generation of our video ingest, transcode and delivery platform. This is a high impact role that influences every video stream that Philo serves. If you endeavor to see how your work directly impacts end-users this is the role for you.

Responsibilities

• Design, implement, deploy and monitor the next generation of Philo’s video streaming pipeline, using a combination of in-house technology and open source software.
• Collaborate with content partners to engineer systems that deliver the best possible TV watching experience for Philo’s users.
• Build scalable and resilient data pipelines for ingesting video and analytics events using distributed computing and micro-services architecture principles.
• Collaborate with internal stakeholders across video delivery, ad operations, and data science teams to ensure we are measuring and optimizing every aspect of our video delivery process and our users’ viewing experience.
• Drive continuous improvements to the reliability, performance, latency and security of Philo’s video streaming platform.
• Drive evaluation, selection, and development of video encoding technologies to optimize video quality and reduce CDN delivery costs.
• Assist our client engineering teams in testing and improving video streaming QoE as we develop Philo apps for several new platforms.

Qualifications

• 8+ years of software development experience.
• Proven track record of building highly efficient and highly available software using Golang, Java, C++ or similar programming languages.
• Deep experience with concurrent programming.
• Experience building concurrent HA and high throughput RESTful web services.
• Experience operating in cloud computing environments using modern software deployment technologies (e.g. Docker, Kubernetes).
• Demonstrated ability to own and drive complex architectural/development tasks to completion by following Scrum/Agile methodologies.
• Experience working with large amounts of data and making data-based decisions to prioritize projects, including familiarity with relational and non-relational databases and modern data warehousing and querying.
• Experience and aptitude for collaborating and communicating with internal and external stakeholders in both business and technical roles.
• Familiarity with cloud video transcoding services such as AWS Elemental and Azure Media Services. Knowledge of FFmpeg is a plus.

Ideal Qualifications

• Experience building or integrating audio and video codecs such as AAC, H.264/AVC, H.265/HEVC and AV1.
• Experience with video quality assessment tools such as VMAF, SSIM, etc.
• Experience with video streaming protocols such as MPEG-DASH, HLS, MPEG TS, fMP4, CMAF, Zixi, and SRT.
• Experience with OTT video packaging and DRM.
• Familiarity with Server-Side Ad Insertion (SSAI).

Bonus Points

• Experienced mentor with a talent for motivating, leading, and inspiring teams to achieve high levels of success.

We are language agnostic, but most of our backend code is written in Golang, Ruby and NodeJS, with some C++ and Python. Our services run on Kubernetes, and we practice continuous deployment across all of our systems.
