POSITION OVERVIEW

•       Position: Red Team Operator-Lead
•       Job Type: Full Time
•       Location: Remote
•       Clearance Requirement:TS/SCI

WHAT YOU’LL DO

SIXGEN is actively seeking candidates for a senior developer lead on RTAI for the Phase III period of performance. The role is approximately 70% hands-on engineering and 30% delivery management — coding along- side the senior architect to ship SOW Task 3 (security hardening and verification) and Task 6 (operator-support enhancements), while owning sprint cadence, ticket management, and packaging of deliverable artifacts and verification evidence for the government customer. The successful candidate will come up to speed quickly on RTAI’s stack and assume primary IC responsibility for assigned deliverables within the first 30 days.

Responsibilities include:

•         Implement Task 6 enhancements across RTAI’s Node.js/Express backend and React/Vite frontend (prompting library, context management UX, workflow guidance, report production, ac- count/permission improvements, PCAP analysis workflow polish, framework-feature configurability)
•         Deliver Task 3 security remediation work: authentication-endpoint rate limiting, encryption- at-rest for sensitive tables and on-disk artifacts, workspace-isolation hardening at the database layer, container-capability tightening, CSRF protections
•         Own day-to-day sprint cadence: backlog grooming, ticket management, sprint planning, and status reporting to internal leadership and the government POC
•         Produce and package deliverable artifacts and verification evidence per SOW requirements (Task 3 verification test cases, Task 6 operational-utility evidence, PCAP accuracy/repeatability characterization)
•         Maintain code quality through reviews, testing discipline, and mentorship of any junior contributors
•         Collaborate with the senior architect on requirements decomposition, technical design, and prioritization

Technology proficiency includes:

•         6+ years combined technical experience across software engineering and IT systems
•         Strong modern JavaScript (ES6+) with backend service development experience
•         React (or comparable modern SPA framework) with current production deployments under your belt

•         Application security fundamentals: authentication, role-based access control, encryption at rest and in transit, OWASP Top-10 awareness
•         Strong written and verbal communication, with demonstrated ability to package technical deliverables for government or regulated customers

Preferred / Will-Train-On

These reflect RTAI’s specific stack. The right candidate is expected to ramp on these within the first 60 days; prior exposure to any of them is a strong plus but is not disqualifying if absent:

o     Node.js / Express server-side development

o     LLM application development against Anthropic, OpenAI, AWS Bedrock, or Ollama SDKs

o     Retrieval-Augmented Generation (RAG) pipelines and vector databases (LanceDB, Pinecone, Qdrant, Weaviate, Milvus, ChromaDB)

o     LangChain or comparable agent/orchestration frameworks

o     Prisma ORM, WebSocket-based real-time features (Express-WS), Tailwind CSS
