About the Product:

Soul Home is a spatial analysis platform that captures a users home in 3D via LiDAR (iPhone Pro), ARCore depth (certified Android), or guided photo capture (fallback tier) — and runs the resulting spatial model through a deterministic rule engine built on classical Vastu Shastra and Feng Shui doctrine. The 3D capture layer you will own is the foundation of the entire product: every downstream analysis depends on an accurate, correctly oriented model of the user’s space.

Core Responsibilities

• Test the LiDAR (iOS), ARCore depth (Android), and photo/panorama fallback capture flows across a range of real devices and room conditions (low light, textureless walls, small/large rooms, reflective surfaces)
• Validate the end-to-end upload lifecycle: capture queue processing status success/failure/retry, as seen by the mobile client
• Perform functional, regression, exploratory, and usability testing on new app builds
• Identify device-specific and OS-version-specific bugs (iOS LiDAR-capable vs non-LiDAR devices; Android ARCore-supported vs unsupported devices)
• Verify object-detection overlays and placement (YOLO-based, 76-object catalog) render correctly in the app
• Test API integration between the mobile app and the backend reconstruction service (job status, retries, error states)
• Document and track bugs with clear repro steps, logs, screen recordings, and device/OS metadata
• Validate UI/UX against design specs, including onboarding and capture-guidance flows for the fallback tier
• Participate in sprint planning and release readiness reviews; sign off on builds before release
• Maintain a device/OS test matrix and a growing regression suite as new capture tiers and features ship

Must-Have Skills

• 2+ years of experience in mobile QA/testing (iOS and/or Android), ideally including AR, camera, or sensor-heavy apps
• Strong understanding of functional, regression, exploratory, and edge-case testing for hardware-dependent features (LiDAR, ARCore, camera)
• Experience testing async/background flows (uploads, job status polling, retries) and validating correct behavior on failure/timeout
• Familiarity with bug tracking tools (Jira, Linear, or similar) and writing clear, reproducible bug reports
• Comfortable reading mobile logs (Xcode console / Android Studio logcat) to help diagnose scan or upload failures
• Basic API testing skills (Postman or similar) to validate the mobile-backend contract
• Access to or experience testing on a range of physical devices (not just simulators/emulators LiDAR and ARCore behavior doesn't reliably emulate)
• Strong attention to detail; comfortable being the person who says "this scan looks geometrically wrong" even without a formal spec for what "right" looks like

Good-to-Have Skills

• Experience testing AR/VR or 3D-capture apps specifically (Polycam, Matterport, RoomPlan-based apps, etc.)
• Familiarity with panorama/360 capture and equirectangular image quirks
• Basic scripting (Python/JavaScript) for light test automation
• Experience with device farms (BrowserStack, Firebase Test Lab) for OS/device coverage
• Understanding of how floor plans, meshes, or spatial models are typically validated for correctness
• Prior QA experience on real-estate, interior design, or spatial-mapping products
