Sr. Backend Software Engineer; Ad Engineering

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.

Philo's video streaming infrastructure is highly distributed, horizontally scalable and harnesses the power of cloud computing. Our OTT pipeline, developed in-house, ingests both live and VOD content from our content partners, dynamically inserts ads into video streams using Server-Side Ad Insertion (SSAI), and optimally delivers them to our growing user base at exabyte scale.

We are seeking an enthusiastic Software Engineer to help us build the future of our ads platform. As a member of a growing team, you will serve as both a technical leader to help us engineer our ad tech stack, as well as an internal subject matter expert on ad technology (both for our platforms as well as trends in the industry at large).

On the business side, Philo is leading the CTV ad industry by focusing 100% on programmatic advertising and resellers, foregoing the traditional direct sales models. At Philo you will be helping to shape the future of television advertising as you build the next generation of our ad business. Collaborating with our Ad Operations and business teams, you will work with our partners to gather requirements, determine the optimal services and partner integrations needed to optimize Philo’s transactions throughout the programmatic ad ecosystem, then go build and operate the services to make that vision a reality.
