OTA Firmware-Update Architecture for a 50,000-Device Smart-Meter Fleet. Expert-level challenge in design. Designing real products under real constraints, ear...
The Brief
What you'll do, and what you'll demonstrate.
Design and validate an OTA architecture that prevents bricking via canary cohorts, signed images, and brick-resistant bootloader handoff across a 50,000-device fleet.
This is not a design exercise. It is the work a product designer does between a brief and a shipped interface. That distinction matters to every hiring manager who has seen candidates redesign Spotify's homepage and none who have worked under real product constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Design staged OTA architectures with telemetry-gated promotion
- Implement signed-image verification and dual-bank rollback safely
- Validate cyber-physical update systems with synthetic failure injection
- Author production runbooks that survive 3am rollout incidents
