The Senior Device Engineer will build software that automates interactions with network-connected devices, ensuring reliable and secure device communication and functionality.
Responsibilities
- Design, build, and ship production software for identifying, fingerprinting, and interacting with network-connected devices across embedded, IoT, and OT/ICS endpoints
- Build and maintain features within the shared frameworks and services that device support is built on, from design through testing and maintenance
- Contribute to migrations and re-architectures of existing systems
- Figure out how devices communicate (undocumented web interfaces and protocols, network traffic captures, hands-on experimentation) and turn that into automated, supported product capabilities
- Troubleshoot complex device issues in production, including hard-to-reproduce and protocol-level problems
- Leverage AI tools and coding assistants as a core part of your day-to-day workflow, including research, code generation, debugging, test creation, and documentation
- Write and maintain automated test cases and frameworks that ensure the integrity of our device coverage
- Mentor other engineers and contribute to code reviews and design discussions
- Collaborate cross-functionally with product, security research, threat research, and customer-facing teams to translate field needs into engineering outcomes
