Job summary

Dragos, Inc. is seeking a Senior Device Engineer to join our remote‑first, mission‑driven team building automation for network‑connected devices across embedded, IoT, and OT/ICS endpoints.

You’ll design, fingerprint, and automate device interactions, work within shared frameworks, and help scale our device coverage. You should have 5+ years building production software, strong Node.js/TypeScript skills, and experience with Go, protocols, and security best practices.

Qualifications

• 5+ years of experience as a software engineer, with a track record of shipping production systems.
• Cybersecurity experience.
• Strong expertise developing and debugging in Node.js, with strong fundamentals in modern JavaScript/TypeScript.
• Experience with Go is strongly valued.
• Strong network protocol analysis skills: interpreting traffic captures, reconstructing device behavior, turning findings into patterns/fingerprints.
• Proficiency with relational databases.
• Unix/Linux environments with systems-level debugging and performance analysis.
• Working proficiency with Docker and containerized development and deployment workflows.
• Understanding of network transport and application layer protocols (TCP/IP, TLS, HTTP, common auth schemes, embedded/industrial protocols).
• Experience using AI coding tools effectively, and judgment about when not to trust them.
• Good communication and collaboration skills in a fast-paced, remote-first environment.
• Experience applying cybersecurity best practices, including secure coding and data protection.
• Bonus: ICS/OT environments, embedded systems, or xIoT device security.

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 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
