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 by USAF , ** AFRC , ** USSTRATCOM , and ** DOS (VIP protection/panic). You’ll build and operate multi-domain, real-time capabilities in ** air-gapped and ** GovCloud environments with strict ** RMF/ATO controls.

What You’ll Do

*   Design and ship **real-time command-and-control workflows** (tasking, tracks, alerts, deconfliction) across air/ground teams.
*   Build **mobile + web mapping** with ** tactical overlays **, historical replay, and multi-user ** collaboration/markup/reporting **.
*   Integrate **sensors & comms** (e.g., CoT/TAK, ADS-B, AIS, Iridium SBD, SATCOM/radio gateways, BFT) into Guardian data planes.
*   Implement **operational chat/voice/video** (XMPP/Matrix/WebRTC/WebSockets) with message persistence and audit in IL5/IL6.
*   Engineer **multi-level security (MLS)** patterns and ** cross-domain** flows (data diode/CDS policy) for SA feeds and alerts.
*   Own **DevSecOps** in 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’s **real time **, ** real users **, and ** zero room for brittle code **. If you’ve only done green-field SaaS, this will feel like another planet—in a good way.

Requirements

Must-have experience (no exceptions)

• 5+ years building ** real-time** systems with ** Java 17+/Spring Boot** and ** Node.js/TypeScript , plus ** React (or React Native) for operational UIs.
• OGC/Geo standards in production: ** WMS/WFS/WMTS **, ** GeoJSON **, ** KML , tiling pipelines; ** CesiumJS or ** Mapbox GL **.
• TAK/CoT ecosystem: generating/consuming ** Cursor-on-Target ; familiarity with ** ATAK plugins or TAK Server integration.
• **Streaming & messaging:Kafka (or NATS/RabbitMQ) + schema mgmt ( Protobuf/Avro **); back-pressure and exactly-once patterns.
• Gov environments: Delivered software inside ** AWS GovCloud (IL4/5)** and ** on-prem IL5/IL6** with ** RMF Steps 1-6 **, ** eMASS , POA&M/SPR; contributed content to an ** ATO package.
• Security hardening: Implemented ** DISA STIG/SRG , ** FIPS 140-2/3 crypto, ** PKI** (smartcard/PIV), authZ with ** ABAC/RBAC **.
• **Observability:Prometheus/Grafana + ** ELK/Opensearch in disconnected enclaves; red/black deployment in air-gapped sites.
• Multi-tenant, multi-domain EA: boundary services (NIPR/SIPR/JWICS), data labeling/marking, and release control across domains.

Nice-to-have (we’ll ask you about it)

• C2/JADC2 touchpoints (Link-16 familiarity, J-series semantics, not necessarily waveform).
• Cross Domain Solutions (e.g., Radiant Mercury, Forcepoint) policy scripting or deployment experience.
• Geospatial toolchain: GDAL, tippecanoe, MBTiles, vector tile pipelines, geofencing at scale.
• Mobile ops: Offline-first data sync, background location, and crypto at rest on ** iOS/Android **.
• **DoD 8570 **: Security+ CE (min), CASP/CISSP nice.
• Infrastructure: K8s (RKE/KE), Packer/Ansible, HashiCorp Vault, artifact signing (cosign/Sigstore).

Day-to-day constraints you’re comfortable with

• Working **inside a SCIF **, no external package registries, ** artifact whitelists **, and ** change control boards **.
• 2-hour incident response windows for operational outages; on-call rotation shared by the team.
• Writing to **operational runbooks **, not just code comments.

Benefits

• PPO or a High Deductible Health Plan, HSA eligible plan, Dental, Vision, and Supplemental Life.
• Generous paid time off that starts accruing on day one.
