IOS AR Engineer

The work is technical and precise, we render directly onto a tracked face mesh at 60fps and every pixel matters. You need to have shipped something real with ARKit. Not a demo. A product where face tracking drove rendering decisions at the vertex level. The work involves: Face mesh geometry and UV mapping Real-time texture generation from geometric contours Sub-pixel optical edge detection against live camera frames Coordinate space transformations between 3D, image, and texture space Threading discipline across ARKit, Vision, CoreGraphics and SceneKit You are the right person if: You have debugged a rendering artifact by reasoning about coordinate spaces, not by guessing blend modes You know what happens to Vision landmark coordinates when you pass the wrong orientation to VNImageRequestHandler You can explain why the same ARKit vertex produces different UV values depending on head angle Working with raw pixel buffers feels normal to you You are not the right person if: Your ARKit experience stops at placing virtual objects in a room You have never read BGRA pixel values directly from a CVPixelBuffer Catmull-Rom splines and even-odd fill rules are unfamiliar Please note, do not apply if you have not done it. I have just had a person who had nod and he wasted time. if you have done it is genuinely just a few hours work.

Android Device Owner/Kiosk Mode Specialist — OEM Provisioning

About StockMyShop StockMyShop Ltd (Company No. 17160242) is a UK-based consumer technology company developing a smart home pantry management system. The product is a retail-ready hardware-software bundle consisting of a dedicated kiosk tablet, a wireless barcode scanner, and a mobile companion app. The StockMyShop application is already fully built and operational. We are not looking for an app developer — we are looking for a specialist who can make a standard Android tablet behave as a locked-down, branded appliance straight out of the box. What We Need: We need an experienced Android kiosk/MDM specialist to deliver the following: * Configure Android Device Owner (or equivalent MDM) kiosk mode on our OEM tablet — single app, no home button, no notifications, no system UI * Coordinate with our OEM manufacturer in China to apply the kiosk profile at the factory, so every unit ships to customers already locked down * Ensure the barcode scanner is Bluetooth pre-paired to the tablet at the factory — no user setup required * Implement auto-boot into the app after power loss and auto-restart if the app crashes * Set up a remote OTA update mechanism so we can push app updates to deployed devices without customer involvement * Optionally: wrap our web app in a native Android/iOS shell for Play Store and App Store submission What Is Already Built: * Full StockMyShop web application (inventory management, barcode scanning, expiry alerts, meal planning, real-time sync) * Cloud backend (Base44 platform — REST API, real-time database) * Mobile companion app (currently web-based, responsive) What We Are NOT Looking For: * General Android or web developers learning kiosk mode for the first time * Agencies — individual specialist or small specialist team only * Day-rate arrangements — this must be a fixed-price milestone contract Contract Structure: Fixed-price, milestone-based. Five milestones from contract signing to production sign-off. Full developer brief including scope, technical environment, QA acceptance criteria, and milestone payment schedule is available under NDA on request. Target Timeline: 10–12 weeks from contract start To Apply, Please Include: 1. Your experience with Android Device Owner / kiosk mode — specific projects, not general claims 2. Your experience coordinating with OEM manufacturers for factory provisioning 3. Your proposed MDM/kiosk solution and why you'd recommend it for this use case 4. A fixed-price quote or indicative range 5. References or examples from similar hardware-software integration projects Applications that do not address all five points above will not be considered.
