Description
Summary I run Rupertsonic Limited, an agency providing AI receptionist, automation and growth systems for UK service businesses. We are looking for an experienced Voice AI Automation Specialist with strong past experience and relevant case studies. This is not a general virtual-assistant role. We are looking for a technical fulfilment partner who can eventually handle approximately 80% of the delivery for client projects from planning through testing and handover. We are currently sourcing and pre-vetting suitable specialists for upcoming paid client implementations. No unpaid build or free custom demo is required during the application stage.

WHAT WE EXPECT FROM A FULFILMENT PARTNER You should be able to handle most of the delivery process, including: - Technical planning - Conversation and call-flow design - Voice AI configuration - Telephony setup - Calendar and CRM integrations - Make.com workflows - SMS and email notifications - Human-transfer logic - Testing and debugging - Client-specific configuration - Loom walkthroughs - Documentation - Final handover You should be able to communicate clearly, identify risks early and recommend solutions without needing instructions for every small task. PROOF OF EXPERIENCE REQUIRED Please include 2–3 relevant examples of previous work. For each example, explain: 1. What you built 2. Which tools you used 3. Which parts you personally completed 4. Whether the system is live 5. What measurable business outcome it achieved Please anchor your results to at least one of the following: - Time saved - Cost saved - Revenue or appointments generated Examples could include: - Hours of staff time saved each week - Reduction in manual administration - Number of calls successfully handled - Appointments booked - Reduction in missed enquiries - Operational costs reduced Live demo numbers, call recordings, Loom walkthroughs, screenshots and client case studies are strongly preferred. Do not submit a generic portfolio without explaining its relevance. CURRENT HIRING PROCESS At this stage, we are: - Reviewing relevant past work - Evaluating technical ability - Comparing hourly rates and fixed-price estimates - Assessing communication and reliability - Confirming availability for future projects - Selecting one primary and one backup fulfilment partner Once a suitable client project is confirmed, the selected freelancer will receive a funded Upwork contract before any project work begins. There is no unpaid development requirement. FUTURE WORK The right freelancer may receive repeated project-based work as Rupertsonic signs new clients. We are not offering a full-time employment role or long-term monthly retainer at this stage. We will begin with individual client projects and expand the relationship based on: - Quality of delivery - Communication - Reliability - Testing standards - Documentation - Measurable client outcomes HOW TO APPLY Start your proposal with: VOICE AI FULFILMENT PARTNER Then answer the following questions: 1.
