CozmoX provides AI employees powered by advanced voice technology that enables natural, human-like conversations.

These digital workers communicate fluently with customers and stakeholders while handling repetitive tasks 24/7. Through our no-code platform, businesses can deploy AI employees that manage entire processes through voice interactions, replacing multiple software tools with unified solutions.

We’ve unveiled 3 powerful AI employees, with more to come: Liza (Sales Executive) - Engages in natural voice conversations throughout the sales cycle, from initial prospect calls to negotiations and closure. She handles qualification calls, follow-ups, and maintains CRM records while building rapport through intelligent dialogue. Alex (Debt Collector) - Conducts professional voice communications for collections, speaking with customers to arrange payments, negotiate plans, and ensure timely follow-ups while maintaining regulatory compliance. Zara (Receptionist) - Masters voice-based front-office management, engaging in natural conversations to route calls, schedule appointments, take detailed messages, and resolve customer inquiries with a friendly, professional tone.

Like the industrial revolution transformed farming, we're revolutionizing workplace communication. By automating routine conversations and tasks, human teams can focus on creativity, problem-solving, and business growth.

We're the first in the Middle East and Africa to offer this kind of technology, but we work with businesses all over the world. We're backed by Y Combinator, Goodwater Capital, Dubai Future District Fund, Rebel Fund, and Trampoline Venture Partners, and have raised $3M in our latest round.

🚀 Who We Are

CozmoX AI is building the world's most advanced AI Employees agents that talk, think, and act. From powering collections to sales and customer support, our AI runs autonomously in the real world, on real calls, at scale.

We’re on track to become the #1 in this category

🧠 What We’re Looking For

We're hiring a Principal Software Engineer who is a do-er, a builder, and a systems thinker — someone who has previously architected and scaled high-throughput enterprise developer platforms (e.g., Twilio, Postman, Segment, Stripe).

This role is critical to building the infra-first backbone of our real-time voice engine, developer tooling, and next-gen orchestration platform. You will be hands-on and deeply involved in everything from code to system design to product vision.

✅ What You’ll Do

• Architect, build, and scale real-time systems for telephony, WebRTC, audio streaming, and AI orchestration
• Design developer-facing infrastructure and APIs that are robust, scalable, and intuitive
• Collaborate directly with founders on platform vision, core architecture, and GTM alignment
• Own performance, latency, reliability, and compliance across voice infrastructure
• Work across cloud, on-prem, and hybrid environments — banking-level security and scalability
• Lead and mentor a high-caliber team of backend and infra engineers

🛠️ Tech Stack You’ll Work With

• Languages: Go, Rust, TypeScript, Python
• Infra: AWS, GCP, DigitalOcean, Kubernetes, Pulumi, Fly.io
• Voice & Media: SIP, RTP, WebRTC, Livekit, Janus, Twilio
• LLMs: OpenAI, Fine-tuned local models (vLLM, SNAC, Whisper)
• Eventing & Workflow: Temporal, NATS, RabbitMQ
• Security & Compliance: SOC 2, GDPR, HIPAA-focused infrastructure

What We’re Looking For

• BONUS (immediate shortlisting): if you are certified in CKA or CKS
• 8+ years of hands-on backend or infra experience
• Previously built or scaled developer platforms (SDKs, APIs, real-time infra)
• Deep understanding of WebRTC, telephony, or media streaming systems
• Comfortable with distributed systems, concurrency, and large-scale event-driven architecture
• Systems-level thinker who cares about execution, speed, and impact
• Strong product sense — you care about what you're building, not just how
• Based in (or willing to relocate to) Bangalore or San Francisco for in-person work

💥 Why Join Us

• Founders who are builders hands-on, fast, and obsessed with quality
• A team that moves fast, avoids meetings, and ships daily
• Backed by top-tier investors like Y Combinator
• Real revenue, real scale, real impact , no fluff

We will provide all the details during the interview process.
