Those critical infrastructure systems that power our civilization around the world are under attack every day by adversaries. When those systems fail, people areimmediatelyat risk.

We are the global leader inxOTcybersecurity, combining technology, threat intelligence, and expert services. The people chose this work because they understandwhat isat 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.
