Applied AI Engineer (Agents & Automations) at Halo AI (remote)

About Us: Halo AI is a passionate startup at the forefront of AI-powered creator marketing. We're building a vibrant community and revolutionizing the way brands connect with influencers. Why we’re hiring We run fast and lean, powered by AI. Your role: be the internal problem-solver who ships scrappy, reliable solutions that unblock GTM, Operations, Product, and Support. From bots and automations to What you’ll do

• Ship working systems: Design, build, and maintain services, scripts, and workflows with clear SLAs.
• Automate everything: Orchestrate workflows (n8n/Make/Zapier/custom) across CRM, APIs, comms channels, and backends.
• Build agentic apps: LangChain/LangGraph-based tools for enrichment, routing, triage, and outreach—with evals, guardrails, retries, and cost controls.
• Scrape responsibly: Headless browsers + official APIs; rotating proxies, backoff, and anti-bot patterns (always within ToS/legal).
• Connect data: Stand up light ETL/ELT to Postgres/BigQuery; implement RAG/search over internal docs; ensure freshness and observability.
• Make it reliable: Logging, metrics, alerts, dashboards, and business-hours on-call for what you ship.
• Document & hand off: Clear runbooks, diagrams, READMEs so others can extend your work.

Sample projects

• Instagram lead intake → compliant DM triage: Collect, enrich, score, and route leads; auto-replies with human handoff; track deliverability.
• AI outreach bot: Segment-based, personalized first touches + follow-ups; dedupe against CRM; A/B prompt + template testing.
• Scrape → Clean → Sync: Playwright job to capture public business data, normalize, and sync to Postgres/Sheets with change detection + alerts.
• RAG for Sales/Success: Vectorize pitch docs and prior wins; build a chat tool that drafts proposals and answers objections with citations.

Our stack

• Languages: Python, TypeScript/Node.js, SQL
• LLM & agents: LangChain, LangGraph, OpenAI/Anthropic APIs, RAG (FAISS/Pinecone/Weaviate), LlamaIndex (bonus)
• Automation/orchestration: n8n, Make, Zapier, serverless cron/queues (BullMQ/Celery), Prefect/Airflow
• Web & scraping: Playwright/Puppeteer, Requests/BS4, Apify, proxies, captcha-solving vendors (when compliant)
• APIs & channels: Meta Graph + Messenger API (IG), WhatsApp Business API, Slack, Telegram, Twilio, SendGrid/Resend
• Data & storage: Postgres/BigQuery, Redis, S3/Cloud Storage, Elastic/OpenSearch, vector DBs
• Infra & DevEx: Docker, GitHub Actions, Vercel/Fly.io/Cloud Run, Terraform (bonus), Sentry/Prometheus/Grafana

What success looks like (90 days)

• 3–5 production workflows/tools live and used weekly
• Idea → pilot cycle ≤ 7 days (small) or ≤ 21 days (medium)
• Telemetry (logs, metrics, alerts) on everything shipped
• Documented SOPs so teammates can run and extend your work

Must-haves

• 4–7+ years building production automations/internal tools in startups or product teams
• Strong in Python + TypeScript/Node; can ship both CLI and small services
• Real LLM app experience (tool use, evals, prompt versioning, cost/perf tuning)
• Confident with APIs, auth, rate-limits, retries, idempotency
• Hands-on with headless browsers/scraping and pragmatic about ToS/legal
• Comfortable with databases, SQL, queues, cloud deploys
• Strong product sense and communication; bias to action

Nice-to-have

• WhatsApp Business API, Meta Graph (IG), Slack/Telegram bots
• Vector search/RAG in production; knowledge graphs (Neo4j)
• Data plumbing: Airbyte, dbt, Great Expectations

How we work

• Small, senior, async-first. Crisp specs, quick demos, strong docs.
• We optimize for business impact > model elegance.
• If it’s blocked, you propose a path and ship.
