Backend Engineer – AI Voice Agent Startup (Work from Home)

Are you a creative and motivated back-end developer who wants to be part of something new, exciting, and game-changing? We’re building a brand-new AI-powered voice agent product that will help small businesses automate customer calls, starting with industries like hairdressers, clinics, and trades.

This is a startup—we’re building the MVP from scratch, and you’ll be working directly with the founder. It’s the perfect opportunity if you’ve ever wanted to help create a real product from the ground up, be part of the early team, and influence how everything works.

What You’ll Be Doing

• Build the backend of our AI Voice Agent platform

• Set up and manage phone call workflows using Twilio or SignalWire

• Integrate AI tools like OpenAI Whisper (STT), GPT-4/Claude (AI reasoning), and ElevenLabs (TTS)

• Connect to external tools like Google Calendar or appointment systems (e.g. Calendly, Fresha)

• Create APIs for future use by a frontend dashboard

• Build internal tools for testing and managing business settings

• Solve real-world problems with AI and voice automation

Why You’ll Love This Role

• You’ll be building something from scratch—this isn’t maintenance work

• Work directly with a founder who understands product, marketing, and operations

• No micro-management. You’ll be trusted to own the tech

• You’ll get exposure to cutting-edge AI tech and be part of something that’s actually cool

• 100% remote. No commutes, just results.

Requirements

• 3+ years of backend development experience (Python preferred, Node.js is also okay)

• Experience with APIs and microservices (FastAPI, Express, etc.)

• Familiarity with AI tools like OpenAI, LangChain, or similar

• Experience working with Twilio or any telephony/VoIP platforms is a BIG plus

• Familiarity with STT/TTS services (Whisper, Google STT, ElevenLabs, Azure, etc.)

• Ability to work independently, solve problems, and think like a builder

• Startup mindset: okay with ambiguity, fast iterations, and learning on the go
