- Cybersecurity experience
- Strong expertise developing and debugging in Node.js, with strong fundamentals in modern JavaScript/TypeScript
- Experience with Go is strongly valued

- 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

- 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
