# Alex Sink > Partner Engineer - Wearables Location: San Francisco, California, United States Profile: https://flows.cv/alexsink 18+ years of experience bridging the gap between hardware/SoC constraints and the Unity Runtime. I specialize in navigating the complex intersection of silicon-aware architecture, developer ecosystems, and product roadmap execution. As an Engineer: I dive deep into C++/C# interoperability, engine-level optimization for Snapdragon XR2, and GPU profiling (RenderDoc/Snapdragon Profiler). As a DevRel Leader: I build "Lighthouse" integrations and SDKs that scale to thousands of developers, reducing integration friction and driving platform adoption. I show people the "happy paths" and help resolve friction points. As a Manager/TPM: I lead high-performance teams, translate complex OEM constraints into actionable roadmaps, and negotiate technical trade-offs between Product, Engineering, and external partners like NASA and NVIDIA. ## Work Experience ### Wearable Partner Engineer - on assignment at Meta @ Tundra Technical Solutions Jan 2026 – Present | San Francisco Bay Area On Assignment to Meta/Reality Labs ### Senior Developer Relations Engineer @ HTC Vive Jan 2021 – Jan 2025 | San Francisco Bay Area Drive HTC’s XR SDK technical strategy across Unity, OpenXR, Android native, and partner integrations, influencing the Wave/OpenXR roadmap based on developer feedback, engine constraints, and OEM requirements.
