Senior Software Engineer - Guardian (C2/SA/Multi-Domain) TS Clearance Required

At Aviture, we’re a team of builders—creating mission-critical software that empowers our customers and makes a real impact. We’re looking for a senior-level engineer who thrives on solving complex problems, cares about good architecture, and wants to work on systems that matter.

Clearance:Active TS/SCI (or TS with SCI eligibility) required; CI poly preferred.
Worksite:On-site (Omaha, NE + customer sites CONUS); periodic work inside IL5/IL6 enclaves.
Citizenship:U.S. only (government program requirement).

Mission

Guardian is Aviture’s C2/situational-awareness platform used byUSAF,AFRC,USSTRATCOM, andDOS(VIP protection/panic). You’ll build and operate multi-domain, real-time capabilities inair-gappedandGovCloudenvironments with strictRMF/ATOcontrols.

What You’ll Do

• Design and shipreal-time command-and-control workflows(tasking, tracks, alerts, deconfliction) across air/ground teams.
• Buildmobile + web mappingwithtactical overlays, historical replay, and multi-usercollaboration/markup/reporting.
• Integratesensors & comms(e.g., CoT/TAK, ADS-B, AIS, Iridium SBD, SATCOM/radio gateways, BFT) into Guardian data planes.
• Implementoperational chat/voice/video(XMPP/Matrix/WebRTC/WebSockets) with message persistence and audit in IL5/IL6.
• Engineermulti-level security (MLS)patterns andcross-domainflows (data diode/CDS policy) for SA feeds and alerts.
• OwnDevSecOpsin restricted networks: reproducible builds, SBOMs, STIG-hardened images, signed artifacts, and offline updates

Why this is hard (and worth it)

You’ll be building capabilities operators rely on in the field. It’sreal time,real users, andzero room for brittle code. If you’ve only done green-field SaaS, this will feel like another planet—in a good way.
