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.

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.

• 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.
• Hybrid work environment with quarterly Castaway Week events in the Omaha HQ Office, all expenses paid, from across the country to participate in team‑building, collaboration, and fun events.
• Company vacations!!! Previous destinations have included Napa Valley, Cancun, Cabo San Lucas and Aspen.
• Matching 401k with 100% vesting in six months.
• Pick your preferred workstation! Mac? PC? We’ll support you with the tech you need to do your best work.
• Get paid to go to national and international conferences and training, so that you can stay up to date with the latest innovations.
• Flexible work schedules: Work the times that fits your schedule, with all meetings required to be scheduled between 9 am and 3 pm CST.
• Free lunch every Friday and recurring team events for you and your family to enjoy.
• Incentive and bonus pay.
• Opportunities for connection and growth through peer coaching, recurring Lightning Talks to share things we’re passionate about, and a bi‑weekly company‑wide All Hands.
