The Brief
What you'll do, and what you'll demonstrate.
Close 3 critical LoRaWAN security findings (default keys, no end-to-end encryption, no rogue-gateway detection) for a 4,800-sensor cold-chain network.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real 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
- Apply LoRaWAN 1.0.x / 1.1 key management correctly across device, network, application
- Layer end-to-end encryption above the LoRaWAN application-layer when 1.1 isn't an option
- Detect rogue gateways using network-server fingerprint logs
- Communicate IoT security posture to a non-technical audit audience
