At Dragos, the mission is personal. The systems we protect deliver the water you drink, power your home, and keep the hospitals your community depends on running. Those critical infrastructure systems that power our civilization around the world are under attack every day by adversaries. When those systems fail, people are  immediately  at risk.  We are the global leader in  xOT  cybersecurity, combining technology, threat intelligence, and expert services. The people here chose this work because they understand  what is  at stake . Here, you will find a remote-first mission-driven team across North America, Europe, the Middle East, and APAC built on authenticity, transparency, and trust. If safeguarding the systems that protect your family, friends, and community is the kind of work that matters to you, you are in the right place.   We are looking for a Senior Device Engineer to join our team. Think of the role as device automation engineering: we build software that interacts with all kinds of network-connected devices, from printers and cameras to door controllers and industrial control systems. That might mean identifying a device, pulling information off it, changing its password, or performing any other action it supports. A big part of the job is figuring out how a device communicates (e.g. from a HAR or PCAP, vendor docs, or a device on the bench) and turning that understanding into reliable, automated capabilities. You will build within the core systems this automation runs on (the shared frameworks, interfaces, and tooling) and work across our scanning and fingerprinting engine, which finds and identifies the devices in the first place.     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     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, working out undocumented or vendor-specific protocols, and turning what you find into patterns and fingerprints (regex and the like)   Proficiency with relational databases   Solid command of Unix/Linux environments, including systems-level debugging and performance analysis   Working proficiency with Docker and containerized development and deployment workflows   Solid understanding of network transport and app
