How We Work

AssetWatch firmware engineers work closely with hardware, test, product, backend, support, cybersecurity, and manufacturing teams. We value engineers who can move from code to bench testing to field diagnostics to documentation without losing the thread.

Because AssetWatch devices operate as connected industrial IoT systems, firmware quality includes communication reliability and security. Engineers are expected to think beyond local device behavior and consider Wi-Fi, Ethernet, cellular, BLE, MQTT, cloud communication, provisioning, credentials, firmware updates, and network diagnostics as part of the product system. We value engineers who can debug a device from the sensor and hub all the way through the network and backend interface while maintaining a security-first mindset.

Our team emphasizes:

· Practical engineering judgment.

· Clear ownership from design through validation and release.

· Lightweight but disciplined Jira planning and issue tracking.

· Pull request reviews and controlled release workflows.

· Changelogs, version control, and repeatable builds.

· Testability, manufacturability, field reliability, and firmware security.

· Documentation that helps other engineers, test teams, support teams, cybersecurity partners, and manufacturing partners move faster.
