About the Role

We design the system, steer the output, and take responsibility for what we ship. Fast where it makes sense. Careful where it matters. We build for the real world, from living rooms to pockets, developing the invisible connection that enables seamless user experiences across a fragmented hardware landscape.

Responsibilities

  • Develop and expand powerful SDKs that reliably function across the entire CTV and Mobile ecosystem.
  • Ensure a consistent technical foundation by identifying overlaps between platforms and merging architectures.
  • Shape the technical and product evolution, balancing rapid feature development with strategic refactoring and technical debt reduction.
  • Implement platform-specific logic based on a shared TypeScript core to ensure native feel.
  • Establish a rigorous testing culture and continuously develop the team through mentoring and code reviews.

Requirements

  • Proficiency in complex TypeScript architectures and ability to work with Vanilla JavaScript when required.
  • Experience in mobile development (e.g., React Native, Kotlin, Swift) or platform-specific device engineering.
  • Understanding of software optimization for resource-constrained environments.
  • Commitment to thorough testing, including edge cases.
  • Ability to bring together diverse technical perspectives and collaborate on solutions.
  • Familiarity with Docker, Kubernetes, and Jenkins is a plus.
  • Experience with Grafana dashboards and Graylog traces for operational issue detection is a plus.
  • A portfolio, side project, or demo repository demonstrating practical implementation skills is valued over a traditional CV.
