As a Senior Software Engineer in the IoT domain you will be responsible for developing critical systems keeping in mind.
Concurrency: You must handle multiple activities concurrently like fetching and sending multiple messages from/to multiple devices at the same time.
Distributed Operations: You must run on a distributed network of multiple servers in different geographies, coordinating through APIs on a microservices architecture.
Scalability: You must scale horizontally as the traffic grows and leverage on the multiple CPU cores of the servers to run parallel threads.
Responsiveness: You must maintain a strict time-frame of <100ms to respond to users and devices, even when the servers are flooded with multiple requests.
Reliability: You must stay in continuous operation for years without any server downtime or restarts even for system updates through hot-swapping.
