Job Ad: AI Voice App Developer (Ultravox + n8n)
Hey! I’m looking for a talented developer to help me build a voice-based English language speaking practice system using Ultravox and n8n.
What We’re Building
A smart, voice-driven assistant that helps English learners practise speaking in real time via WhatsApp. Here’s a rough flow of how the system will work:
CALL FLOW
Stage 1 – Membership Check
The assistant checks if the caller is a paid user.
- If not, it explains pricing, answers questions, encourages an upgrade, and ends the call.
Stage 2 – Goal Setting
If the user is paid, it asks what kind of speaking practice they want (e.g. job interview, casual chat, academic speaking).
Stage 3 – Escalation to Teacher (me)
Based on their response, the assistant routes the call to my AI voice clone (“Jay”) via Ultravox.
Stage 4 – Speaking Practice
Jay then leads a tailored speaking activity based on the user’s goals.
Tech Requirements
You’ll help build the system using:
- Ultravox for the voice agent
- n8n for prompt and logic control
- A lightweight dashboard (can be Airtable, Notion, or something custom) to:
- View call summaries & durations
- Track user history
- Store conversational data
I also want the ability to:
- Easily tweak prompts and flow logic
- Store summaries of each interaction for more personalised future calls
What I’m Looking For
- Experience building with voice agents (Ultravox, Twilio or similar)
- Comfort with tools like n8n / low-code automation
- Ability to build simple, clean dashboards or UIs
- Bonus: Experience with Twilio, Airtable, Firebase, etc.
Budget & Timeline
- Budget: Open to discussion, but reasonable — especially if you can reuse existing code/flows, which I have
- I’ll provide code, JSONs and prompt flows from my other systems to help you get started quickly
