Job Summary

Your Career

As a member of the Unit 42, National Security (NATSEC) team, you will be working closely with a globally distributed team of vulnerability researchers, reverse engineers, and threat intelligence analysts. In this role you will work with the Cyber Research Engineering team to conduct investigations into global network infrastructure in support of both government and commercial customer requirements. 

Your Impact

  • Lead investigations end-to-end in response to customer intelligence requirements, from inquiry through collection and analysis to delivered product.

  • Investigate adversary infrastructure, exposures, and observable activity across large datasets, correlating signals at gigabyte-to-petabyte scale.

  • Build the tooling and infrastructure investigations require.

  • Produce finished intelligence in both strategic and technical registers, from senior-leader assessments to analyst-to-analyst methodology write-ups and indicators.

  • Innovate, develop, and implement new methods, capabilities, or customer deliverables.

  • Research unfamiliar products or protocols as investigations require, design the collection to characterise them, and interpret the results.

  • Design and deploy custom Internet scanning to collect what existing platforms don't cover, including probe development, scan infrastructure decisions (attribution, geographic origin, hosting), and analysis of results.

  • Set technical direction for investigations and raise the craft across the team in data work, collection design, source evaluation, and report writing.

  • Shape which investigations the team prioritises and which capabilities we build next.

Qualifications

Your Experience

  • Have or be eligible for a DV-level security clearance.

  • BS/MS in Computer Science, Computer Engineering, or 5+ years of experience as a cyber threat intelligence analyst.

  • Experience producing written intelligence products across both strategic and technical registers for government, intelligence community, or commercial equivalents.

  • Experience leveraging netflow, passive DNS, IP registration, malware telemetry, and other data sets to form comprehensive threat assessments.

  • Broad knowledge of nation-state APT groups and how their tactics, techniques, and procedures differ.

  • Fluency in SQL at scale, with the analytical instincts to know what to ask of the data.

  • Proficiency in Python, Rust, or Go.

  • Deep understanding of how the Internet works: routing, the devices that move information, and the protocols carrying them.

  • Experience standing up the infrastructure and tooling required to deliver an investigation, not just executing existing playbooks.

  • Hands-on experience with active Internet scanning — designing probes, executing collection at scale, and analyzing responses.

  • Experience researching unfamiliar products or protocols, designing collection to characterise them, and producing intelligence findings from the results.

  • Comfortable explaining technical findings to senior government stakeholders.

  • Fluent in written and spoken English at the standard required for finished intelligence.
