Who We Are:

We're a small, high-impact team building a next-generation TV operating system. Our flexible structure gives engineers direct influence over product direction—an opportunity rarely found in larger companies.

Our public API stack is TypeScript, while many backend systems leverage Java, Python, Aerospike, and PostgreSQL. We prioritize problem-solving, scalable architecture, security expertise, and innovation over specific tech stacks.

Our Senior Engineers are end-to-end owners. You'll design and build scalable, secure APIs that power our TV OS, impacting millions of users. Your work will span identity solutions, authentication, and high-performance backend systems, all with a strong focus on observability.

Play a key role in shaping the future of TV—our OS is set to disrupt the industry.
