Job Description

Company Description

Location: Berlin or Köln (50 % Remote possible)

We use AI to accelerate – not to replace thinking.

We design the system, steer the output, and take responsibility for what we ship.

Fast where it makes sense. Careful where it matters.

Job Description

The Challenge

Most developers build for the perfect environment: the latest OS on high-end hardware. We build for the real world. From the living room (FireTV, AppleTV) to the palm of the hand (iOS, Android) – we create the invisible glue that makes seamless experiences possible across a fragmented hardware universe.

At smartclip, you don't just write components; you define how they interact. You make sure every platform we support – from the living room to the phone in someone's pocket – shares one coherent, scalable architecture instead of a patchwork of one-off solutions.

Your Mission

• Cross-Platform Engineering: Develop and evolve high-performance SDKs that run flawlessly across the entire CTV and Mobile ecosystem (AppleTV, FireTV, Android, HbbTV, iOS).
• Strategic Synergy & Alignment: Drive technical cohesion by identifying platform overlaps and aligning architectures to ensure a unified language across all SDKs and tools.
• Technical Ownership & Roadmap: Influence the product direction by balancing rapid feature delivery with strategic refactoring and the reduction of technical debt.
• Native Performance & Depth: Implement platform-specific logic on top of a shared TypeScript core to ensure our SDKs feel truly native on every operating system.
• Quality & Mentorship: Establish a bulletproof testing culture using Jest and Vitest, while elevating the team through mentorship and high-standard code reviews.

Qualifications

Your Skills

• TypeScript Powerhouse: You moved beyond the basics to work on complex architectures – and can still find your way through Vanilla JavaScript when a platform demands it.
• Cross-Platform Mindset: Experience in Mobile development (React Native, Kotlin, Swift) or device-specific engineering. You understand how to optimise for limited resources.
• Testing Obsession: You don't ship until the edge cases are conquered. Jest and Vitest are your primary weapons.
• Collaboration Spirit: You enjoy being the „Networker“ who brings different technical perspectives together to find the best solution.

​​​​​​​Bonus XP (The Edge):

• Knowledge of Docker, Kubernetes, and Jenkins.
• Ability to navigate Grafana dashboards and Graylog traces to pinpoint issues in the wild.
