About the role
We're an early-stage startup building an AI-powered business calling platform — think a modern cloud calling system for sales and support teams, with an intelligence layer that learns from every conversation. We already have the AI/agent-intelligence side covered. Now we need a founding full-stack engineer to build the core product and own it end-to-end.
This is a 0→1, high-ownership role. You won't be a cog maintaining someone else's code; you'll architect and ship the platform from scratch, work directly with the founder, and see your work in customers' hands within weeks.
What you'll build
- The cloud calling platform on Twilio - outbound & inbound calls, call routing, IVR, call recording, and number provisioning via API.
- An in-browser softphone(click-to-call) using the Twilio Voice SDK / WebRTC.
- Call logging, team & user management, and an analytics dashboard.
- CRM integrations(e.g., HubSpot, Salesforce, Zoho) and no-code automation for follow-ups.
- The integration layer for our AI engine, plugging in transcription, call summaries, an agent copilot, and (over time) autonomous call handling, was built by our AI engineer.
- A reliable, scalable call infrastructure, event-driven, webhook-heavy, built to handle real call volume.
Must-have
- 2-3 years full-stack experience shipping production software.
- Hands-on Twilio Programmable Voice in production (calls, TwiML, webhooks, Numbers API).
- WebRTC / Twilio Voice SDK experience (browser-based calling).
- Strong backend(Node.js and/or Python) and frontend(React / Next.js).
- Comfort with event-driven systems, webhooks, REST APIs, and queues.
- Solid with SQL/NoSQL databases and a cloud platform (AWS or GCP).
- A0→1 builder mindset— ownership, speed, and comfort with ambiguity.
Nice-to-have
- DeeperSIP / VoIPknowledge; experience with call-center or telephony products.
- Experience integrating LLM APIs(Anthropic / OpenAI) or speech-to-text(Whisper / Deepgram / AssemblyAI).
- Awareness of telecom compliance(e.g., India TRAI/DND for outbound calling).
- CI/CD, automated testing, and a security-conscious approach.
Why join
- Founding engineer, ownership of the entire product and architecture.
- Meaningful equity and a direct line to the founder.
- Build a genuinely ambitious AI calling product, not another dashboard.
- Move fast, ship real things, and shape the company from day one.
