TLDR

Own and evolve external developer documentation end-to-end, validate integration work with sample apps in Swift or Kotlin, and support a diverse global team impacting hundreds of millions of users.

adjoe builds the technologies behind mobile apps growth and monetization. With our core product Playtime Arcade, we've become the global leader in rewarded advertising, an ad unit built on a simple premise: users earn real in-app rewards for engaging with new apps. The result is one of the most effective value exchanges in adtech, connecting advertisers and publishers with over 770 million users annually. Creating solutions that run on 13% of the world’s smartphones The Mobile Integrations team builds the core technology that turns advertising from an interruption into a rewarded experience for 770 million users. We own the robust, lightweight,integration layer between our ad engine and the global mobile ecosystem, ensuring our technology operates with minimal overhead while reaching a massive portion of the smartphone market. On the client side,our technology performs smoothly across 20 million daily SDK initializations. We build native Swift and Kotlin SDKs optimized for ms initialization and minimal binary overhead, with Unity, Flutter, and React Native wrappers that provide a unified API across the entire mobile ecosystem. Behind the scenes, a high-throughput Go and DynamoDB architecture handles the real-time state synchronization of millions of concurrent sessions. When your code runs on nearly one out of every seven smartphones on Earth, every millisecond of execution and every byte of memory counts. Your Mission & Who We Are Looking For:

Documentation is your product. You have 2–4+ years in Developer Relations, Solutions Engineering, or Technical Account Management. You own and evolve external developer documentation end-to-end: API references, SDK guides, integration tutorials, and example applications, and treat it with the same rigor as shipping code. You drive documentation standards and consistency across teams.

You build to validate. You create lightweight demos and sample apps in Swift or Kotlin to test and support what you document. You contribute directly to documentation tooling like Docusaurus, including Markdown, frontend components, and styling. You're comfortable with mobile SDKs, APIs, HTML, and JavaScript/TypeScript to identify friction in the developer experience and fix it.

AI-assisted, not AI-dependent. You use code copilots and LLMs to explore unfamiliar codebases, analyze SDKs, and accelerate content creation, but you validate every output for technical accuracy. You're also comfortable building and maintaining AI tools, like publisher-facing integration assistants, to reduce integration friction at scale.

Debugging is part of the job. On the support side, you perform root cause analysis across mobile apps, APIs, and data flows, working with SQL, dashboards, and logs to investigate integration health and performance issues. You collaborate with TAMs and Growth Managers on technical escalations.

Cross-functional and cross-regional by default. You manage multiple documentation and integration projects in parallel, work across Product, Engineering, and Product Marketing to deliver documentation at launch, and optimize resources culturally and linguistically across regions. Strong organizational skills and the ability to bring structure where none exists are a must. AdTech, mobile monetization, or SDK-based product experience is a strong plus.

🌎 We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.
