Job Description

Responsibilities: 
•    Build deep technical expertise in a proprietary integration framework used by partner game studios, and apply that expertise to support those studios directly 
•    Own the integration documentation and sample code, and build tooling and test plans that prove an integration is correct 
•    Roll up your sleeves and debug alongside partner studios when an integration doesn't behave the way the API promised 
•    Serve as the primary engineering point of contact for partner developers through office hours, direct correspondence, and hands-on support 
•    Triage incoming issues, separating partner-side integration mistakes from genuine framework bugs, and file well-reproduced reports back to the framework's engineering team 
•    Turn recurring pitfalls into documentation, self-serve tooling, and feedback that shapes the framework's roadmap 
•    Build and maintain a Unity plug-in wrapper around the framework to make adoption dramatically easier for studios building in Unity 
•    Operate in a hybrid developer-relations / partner-engineering capacity, supporting live integrations while the API surface continues to evolve 

Requirements:
•    6-10 years of professional software engineering experience, with meaningful mobile app platform experience; iOS strongly preferred 
•    Strong Swift and/or Objective-C skills, with solid working knowledge of Xcode, app store distribution, and app launch and lifecycle sequencing 
•    Working proficiency in Unity and C#, sufficient to build and maintain a plug-in consumed by third-party developers 
•    Prior experience in developer relations, partner engineering, technical support, or an SDK-integration-facing role 
•    Excellent oral and written communication skills, with the ability to turn an evolving API into clear, actionable developer guidance 
•    Demonstrated ability to manage and triage a high volume of concurrent partner requests without losing quality of support

Duration: 8 months (possible extensions)
