Security Engineer, RF and Technical Surveillance Countermeasures

Own end-to-end RF monitoring, detection, and technical surveillance countermeasures across data center sites, including evidence, alerting, and pre-opening sign-off.

Responsibilities

• Design and develop on-site RF monitoring and detection for each site, including sensor, receiver, and antenna selection and placement, spectrum monitoring architecture, and RF baselines with processes to keep them current
• Build detection and classification tooling, including instruments and software for checks between sweeps, plus findings and evidence records that support alert trust for security monitoring analysts
• Develop tools or agents to retire review tasks that repeatedly cost time
• Own technical surveillance countermeasures (TSCM) end to end: define sweep cadence by space sensitivity, set event-driven triggers (fit-out, room turnover, incident), establish per-sweep scope and acceptance criteria, and ensure findings are handled with evidence and closure that an assessor accepts
• Set site posture requirements, including assessment method, zoning and separation, and shielding, filtering, and protected cabling where warranted, documented in design and build standards for implementation and assessor verification
• Detect which radios are actually present by location (cellular, Wi-Fi, Bluetooth, IoT, trunked radio) and produce evidence that policy requirements hold on the floor
• Define sweep and assessment scope and deliverable standards, direct work on site, and determine in the acceptance review whether a report meets requirements
• Carry RF and emanations requirements into design reviews, lease terms, and pre-opening reviews; perform and sign off RF and emanations activities, including pre-opening sweep and assessment, before a site opens

Requirements

• Built at least one RF monitoring or detection system end to end, from receiver and antenna selection through software that turns captures into alerts
• Engineering-level understanding of propagation, modulation, spectrum analysis, and antenna behavior, with hands-on use of spectrum analyzers and software-defined radios
• Planned and conducted TSCM sweeps, with ability to explain what a sweep can and cannot find and how an adversary could bypass it
• Hands-on RF security, TSCM, or emanations work experience for data centers, critical infrastructure, or large hardware fleets
• Ability to read and review code, understand the data systems behind monitoring and detection tooling, and build automation (often using AI coding agents) using Git and code review
• Understand compromising emanations and the tradeoffs for zoning, shielding, and filtering; write requirements that construction teams or landlords can build and assessors can test
• Ability to direct and validate specialist vendor work independently, including writing scope, checking results, and rejecting weak reports

Technologies

• Git
• Code review
• AI coding agents

Benefits

• Competitive compensation and benefits
• Optional equity donation matching
• Generous vacation and parental leave
• Flexible working hours
• Lovely office space for collaboration

Preferred Qualifications

• Experience assessing compromising emanations and shielding or filtering tradeoffs in a live facility; applying a formal emanations or counter-surveillance standard (TEMPEST, ICD 705 style construction requirements, or a corporate equivalent)
• Experience building signal classification or spectrum analysis pipelines at scale, or tuning RF detections for a security operations workflow so operators kept trusting them
• Familiarity with airspace or drone RF detection, including where airspace detection ends and on-site monitoring begins
• Experience at sites not fully controlled by you, such as colocation or multi-tenant facilities where the RF environment and walls are not yours alone
• Experience building AI agents or automation that replaced recurring manual security work

• $320,000 - $405,000 USD per year
