Responsibilities
Responsibilities
We are looking for a full-stack software engineer to build and extend an offline, edge AI data-triage application through a rapid prototype and its redeployment as mission needs evolve. The application runs entirely on a single, standalone device with no network connection. Technical tasks include:
  • TS/SCI with polygraph
  • Building and extending the offline, standalone application (Python/Flask) that ingests documents, images, audio, and video and runs locally hosted AI models to translate, summarize, extract entities, and catalog content
  • Developing the browser-based local user interface: ingest dashboard, tag filters, search, and a natural-language question interface
  • Integrating and operating on-device AI/ML components, including local open-weight language models, retrieval-augmented generation, a vector store and embeddings, speech transcription, and multimodal vision models
  • Building the controlled sandbox and data-security features: malware scanning and rule-based detection, file-type allow-listing, a quarantine landing zone, unprivileged containers with read-only mounts, and ephemeral teardown on shutdown
  • Packaging the application for standalone, offline installation on a zero-trust Linux laptop baseline, including single-package and side-load delivery across enclave boundaries
  • Maintaining a self-hosted CI/CD pipeline and cutting versioned releases that record model and behavior changes
  • Validating near-real-time processing against edge data loads from 128 GB to 1 TB across text, image, audio, and video
  • Supporting redeployment and iteration of the capability after the prototype as requirements change

Qualifications
Required Qualifications:
  • Front-end web development with JavaScript, HTML, and CSS for browser-based interfaces
  • Strong Python, including backend web development (Flask or equivalent)
  • Containerization with Docker and comfort working on Linux (Rocky Linux or the RHEL family)
  • Experience integrating AI/ML or large language model components into applications
  • Experience with data workflows using relational databases and/or vector stores

Desired Qualifications:
  • Local or offline LLM tooling (e.g., Ollama) and retrieval-augmented generation (RAG)
  • Vector databases (e.g., ChromaDB) and sentence embeddings (e.g., all-MiniLM)
  • Speech-to-text (Whisper / faster-whisper) and multimodal vision models
  • Text extraction (Apache Tika) and metadata standards (Dublin Core)
  • Application security and sandboxing: ClamAV, YARA, unprivileged containers, encryption, role-based access control
  • Self-hosted CI/CD and Git for source control
  • Building for air-gapped, disconnected, or edge environments and standalone portable devices

What you can expect from us
  • The expected salary range within the Washington, DC metropolitan area is: $165,000 - 195,000. Final compensation is unique to each individual and will be determined based on factors such as experience, education, geographic location, and contractual requirements. This is not a guarantee.
  • Benefits include Health/Dental/Vision, 401(k), Paid Time Off, STD/LTD/Life Insurance/Voluntary Life Insurance, Stipends, Referral Bonuses, and more.
