About the Role

Daemo AI is an intelligence platform catering to middle-market and enterprise clients. This engineer owns the full stack — from real-time data pipelines and LLM summarization engines to the user-facing web portal.

  • TypeScript (Expert) — all production frontend/backend code
  • Python (Proficient) — pipelines, scraping, LLM orchestration
  • SQL / MongoDB (Proficient) — BigQuery ingestion, aggregation pipelines
  • Bash/Shell — EC2 ops, cron, deployment scripts
  • Rust — systems on Rust

Frameworks & Infrastructure

  • Next.js (App Router), React, Tailwind CSS / shadcn/ui, NextAuth.js
  • Node.js + Server Actions, OpenAI-compatible API (streaming, tool calling)
  • MongoDB Atlas — document modeling, Atlas Search
  • Docker / Docker Compose — all services containerized
  • Linux / tmux — SSH, process management, EC2 service administration

Engineering Capabilities

  • Full stack ownership: data model → API → UI → deploy (no tier handoff)
  • Async/concurrent systems & data pipeline architecture (ETL/ELT, deduplication)
  • Web scraping at scale — anti-bot evasion, government/political sources (Playwright, BeautifulSoup)
  • Real-time streaming — SSE/WebSockets for agent responses
  • Production debugging across multi-stage pipelines
  • Multi-tenant security — data isolation, access control, audit logging

AI / LLM

  • LLM API integration — chat completions, tool/function calling, streaming, context management
  • Prompt engineering for summarization, personas, research agents
  • Agent architecture — multi-step tool use, memory patterns, RAG
  • AI output evaluation — hallucination detection, guardrails

Preferred Skills

  • Rust — core system runs on Rust
  • AWS Bedrock — Claude 3.x families; cost/quality/latency tradeoffs
  • AWS (EC2, S3), Cloudflare (DNS, tunnels), CI/CD (GitHub Actions)
  • Google BigQuery — large-scale parallel data ingestion
  • Redis — caching, job queuing, pub/sub
  • Signal CLI — secure messaging integration on Linux EC2
  • Multi-provider LLM routing (Fireworks AI or similar)
