Job Description

Own cybersecurity for fielded Air Force Portable Doppler Radar (PDR) systems and supporting software, focused on patching, DISA STIG scanning, Tenable/ACAS scanning, and RMF/ATO evidence for often air-gapped deployments (not a SOC).

Responsibilities

Own the Air Force PDR patch process: plan, test, package, and apply OS and application patches to radar servers and operator stations on the recurring AF calendar
Run quarterly DISA STIG scans (including the Q2 STIG cycle) across Linux, Windows, web, database, and application stacks used by PDR and related systems
Perform Tenable (Nessus / ACAS) scanning, triage findings, remediate or document residual risk using POA&Ms, and generate packages the USAF program office will accept
Maintain the security baseline for fielded, often air-gapped radars, including offline updates, local accounts, certificates, SSH, firewall configuration, and adherence to customer constraints (including no-Java / isolated networks)
Collaborate with Watch and related software so authentication, TLS, logging, containers, ports, and configuration changes remain inside the accredited baseline
Keep RMF / ATO evidence current: STIGs, scan outputs, hardware/software inventory, configuration baselines, and change records
Coordinate with EWR engineering in Kirkwood and with USAF PDR stakeholders for patch, STIG, and Tenable review cycles
Occasional travel to U.S. or international customer sites; day-to-day work from the Kirkwood office

Requirements

U.S. citizenship
Ability to obtain and maintain a DoD Secret clearance (active Secret preferred)
Hands-on DISA STIG execution experience, including applying STIGs (not only reading them), using tools such as STIG Viewer, SCC, Evaluate-STIG, or equivalent
Hands-on Tenable or ACAS experience: scanning, false-positive handling, remediation, and residual-risk write-ups
Linux administration for non-cloud-console servers (RHEL, Ubuntu, or similar), including packages, services, firewall, and logs/certificates
Windows server/workstation hardening in a DoD context
Patch management experience for systems that cannot be casually rebooted or updated from the internet
Clear written English for scan reports, POA&Ms, and patch notes that a program office can file

Technologies

C#, .NET, Linux, Docker
DISA STIG, Tenable (Nessus / ACAS), STIG Viewer, SCC, Evaluate-STIG
RHEL, Ubuntu, Windows, SSH, TLS
nginx, Apache, PostgreSQL
RMF, NIST SP 800-53, NIST SP 800-37, NIST SP 800-171, CMMC
CompTIA Security+, CySA+, CISSP

Clearance

Must be a U.S. citizen and able to obtain and maintain a DoD Secret security clearance
Employment is contingent on remaining eligible for Secret
Active Secret is preferred, but sponsorship may be possible to start
Cannot hold the job if unable to be granted Secret

Strongly Preferred

Active Secret clearance
DoD RMF experience (NIST SP 800-53 / 800-37) supporting an ATO or ongoing authorization
DISA STIG experience for nginx/Apache, PostgreSQL, .NET, and Docker/containers, plus Windows
CMMC / NIST SP 800-171 experience in a small contractor environment
Enough C# / .NET or application-security background to work alongside Watch developers
Docker/nginx on Linux experience in offline or field-deployed systems
CompTIA Security+, CySA+, CISSP, or another DoD 8140/8570 baseline certification
Prior USAF, USMC, or other DoD C5ISR / weather / radar / industrial-control adjacent work

Benefits

401(k)
Dental insurance
Health insurance
Paid time off
Vision insurance

How Work Is Structured

EWR is a small manufacturer (tens of people); you own cybersecurity for PDR and related products across servers, scan tools, and paperwork
Work alongside engineering in Kirkwood, not in a separate security department
Resume should name specific STIGs, scanners, OS versions, and programs you have touched
Include clearance status (active Secret, previously held, or eligible/never held)
“Familiar with NIST” without scan/remediation evidence is not competitive

Not this role: 9-to-5 SOC watching SIEM alerts; GRC-only with no system access; cloud-native “zero trust in AWS” work. These radars are physical and often isolated, and must stay operational.
