QA Engineer (Manual) — InkPoster Digital Frame

About the project  - inkposter.com

InkPoster is a Wi-Fi–connected digital art frame with a companion mobile app and a cloud backend. You'll test the whole chain: app → API → device.

What you'll do

• Test the iOS and Android apps: functional, regression, UI/UX, cross-device.
• Test the REST API and backend logic (Postman, Charles/Proxyman, reading logs).
• Test device connectivity end to end: BLE pairing, Wi-Fi provisioning, image delivery to the frame, OTA updates, reconnection and offline behaviour.
• Write and maintain test cases and checklists; report and verify bugs in Jira.
• Reproduce field issues on real hardware and work closely with mobile, backend and firmware engineers.

Requirements

• 2+ years in manual QA, ideally with mobile apps.
• Solid understanding of client–server architecture: HTTP/REST, request/response, status codes, JSON, authentication, caching.
• Practical knowledge of networking: Wi-Fi standards and bands (2.4 GHz vs 5 GHz, 802.11 b/g/n/ac/ax), routers, DHCP/DNS, captive portals, signal strength and interference.
• Understanding of Bluetooth and BLE: pairing, GATT basics, typical connection failures.
• Hands-on API testing with Postman or similar; comfortable reading server and device logs.
• Experience testing physical devices / IoT is a strong plus.
• Structured, detail-oriented, able to isolate whether a bug lives in the app, the API or the device.
• English: B1+ (written communication with the team).

Nice to have

•  experience with e-ink or consumer hardware, familiarity with MQTT/WebSockets, basic API automation.

We offer

• Fully remote, full-time role in a product team building real hardware.
• Direct impact on a shipping consumer device.
