Job Description

Ursa Major is seeking a Senior Cybersecurity Engineer to support its Digital Operations team, bridging day-to-day commercial enterprise activities with cleared defense program execution. This Level 3 role includes hands-on security engineering and leadership across classified spaces, secure labs, and air-gapped networks, with direct involvement in RMF and JSIG lifecycle work, plus CMMC Level 2 posture.

Role focus

In this position, you will work across engineering and security boundaries to manage CUI and classified data flows safely, while maintaining momentum for hardware engineering, CAD/CAM development, and classified testing. You will also take point on complex security segmentation challenges, leading diagnosis and resolution with minimal supervision.

Responsibilities

Partner with non-cyber stakeholders, including program managers, propulsion engineers, test stand operators, and cleared defense leads, to understand workflows and safely manage CUI and classified data flows.
Apply practical security approaches that align with federal expectations including RMF, NIST SP 800-53, and NIST SP 800-171 while avoiding unnecessary operational friction.
Design controls that fit engineering workflows to reduce latency and eliminate operational bottlenecks.
Lead hands-on security engineering, vulnerability management, and continuous monitoring across classified program enclaves, air-gapped networks, and secure testing environments.
Execute RMF and JSIG lifecycle tasks, including system hardening using STIGs/SCAP, vulnerability scanning (ACAS/Tenable), eMASS package management, System Security Plan (SSP) authoring, and POA&M remediation.
Manage and optimize technical security controls across both enterprise and classified network environments, including EDR, SIEM log aggregation, firewalls, and identity platforms.
Serve as a subject matter expert for ambiguous, high-complexity security segmentation issues with end-to-end ownership.
Collaborate with physical security, FSO, and ISSM staff to support secure facility operations, media sanitization, DCSA audit readiness, and classified authorization packages.
Provide technical guidance and mentorship to junior staff and IT team members by translating federal requirements into clear, actionable guidance for non-cyber stakeholders.

Requirements

Active DoD Secret clearance required (Top Secret or TS/SCI eligibility highly preferred).
4+ years of dedicated cybersecurity engineering experience in DoD, cleared defense contractor, or high-rigor regulated environments.
Current DoD 8570/8140 IAM/IAT Level II or III certification (examples include Security+, CISSP, CISM, CASP+, or CySA+).
Deep familiarity with government regulations, specifically NIST SP 800-171, CMMC Level 2, NIST SP 800-53, RMF, and JSIG requirements.
Demonstrated experience executing STIG hardening, SCAP compliance scanning, vulnerability remediation, and EDR/SIEM administration across air-gapped or classified Windows/Linux environments.
Proven track record working constructively with engineering and business stakeholders, emphasizing trust-building, communication, and enabling business outcomes.
