n8n Automation Expert for AI Video Pipeline

We are building an automated content engine that produces short-form social media videos and training videos, posts them across multiple platforms, and feeds performance data back into a research loop to decide what to produce next. We have a detailed architecture concept ready (attached) and are looking for an experienced automation developer to build it. **What you'll build:** 1. **Research module** – pulls trending topics & keywords via APIs (e.g. OutlierKit, VidIQ) and our own performance data to prioritize content. 2. **Script & prompt engine** – generates scripts from a versioned, tagged prompt library (Airtable/Notion/Sheets) using an LLM (Claude/GPT). 3. **Media generation** – video via Grok Imagine / Veo APIs, voiceover via ElevenLabs, avatars via HeyGen/Synthesia for training content, plus music/sound. 4. **Assembly** – stitch scenes + voice + music + captions into finished clips. 5. **Media library** – tagged asset storage so clips/scenes can be reused and re-edited (incl. repurposing long videos via OpusClip/quso). 6. **Auto-posting** – publish to TikTok, Reels, YouTube Shorts, LinkedIn, X, etc. (e.g. via Blotato) with platform-specific captions, tags, keywords and thumbnails. 7. **Feedback loop** – collect views/engagement via platform APIs, write to a control sheet, feed back into the research module. **Orchestration:** n8n (self-hosted or cloud) as the backbone, with a Google Sheets / Airtable control center. **Required skills:** - Proven experience with **n8n** (or Make.com) building complex, multi-step workflows - Strong **REST API integration** experience (auth, webhooks, rate limits, error handling) - Experience integrating **AI APIs**: LLMs, video generation (Grok/Veo/Sora), TTS (ElevenLabs) - Experience with **social media posting APIs / tools** (Blotato, Buffer, or native platform APIs) - Familiarity with content automation pipelines is a big plus - Clear English communication and reliable updates **Deliverables:** - Fully working pipeline, modular and documented - Setup/handover documentation so we can run and extend it ourselves - A short walkthrough/training session **Budget & timeline:** - [Fixed price / hourly – your choice]. Indicative budget: [€___]. Target timeline: [___ weeks]. - We prefer a **phased / milestone-based** approach (first one working format end-to-end, then scale). **To apply, please answer:** 1. Briefly describe a comparable automation pipeline you've built (with links/screenshots if possible). 2. Which video generation and posting APIs/tools have you integrated before? 3. How would you approach the feedback loop (collecting and reusing performance data)? 4. Your estimated effort/cost for **Phase 1** (one format, end-to-end). We will share the full architecture concept with shortlisted candidates.
