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.
About the Role:
Dragos is seeking a Staff 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 and own 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
- Own the shared frameworks and services that device support is built on, and evolve them end-to-end: architecture, implementation, testing, tooling, and maintenance
- Help lead major 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
- Do the manual work when it's needed (build device support by hand, review device data), then build the automation/tooling that makes the next one easier
- Set technical direction on 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
- Design and maintain automated test cases and frameworks that ensure the integrity of our device coverage
- Mentor engineers, lead code reviews, and grow the technical depth of the team through pairing, design reviews, and knowledge sharing
- Collaborate cross-functionally with product, security research, threat research, and customer-facing teams to translate field needs into engineering outcomes
Qualifications:
- 8+ years of experience as a software engineer, with a track record of shipping production systems and owning complex technical work
- Deep 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
- Strong 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 application layer protocols (TCP/IP, TLS, HTTP, common auth schemes, and common embedded/industrial protocols)
- Experience using AI coding tools effectively, and judgment about when not to trust them
- Demonstrated ability to mentor engineers, lead technical design discussions, and influence direction across teams
- Excellent communication and collaboration skills, with the ability to work effectively in a fast-paced, evolving, remote-first environment
- Bonus: experience with ICS/OT environments, embedded systems, or xIoT device security
Compensation:
- Salary: $192,000
- Competitive Equity Package
- Comprehensive Benefits Plan
