About Cosmium AI

Cosmium AI is an early-stage startup founded by IIT Delhi alumni, building the next generation of conversational Speech AI products. We move fast, ship often, and value extreme ownership. We are looking for a builder who wants to architect systems, not just write tickets.

What You'll Do

  • Own the Stack: Build and maintain our Django/DRF backend, React web dashboard, and React Native mobile apps.
  • Ship AI: Integrate real-time Speech AI and ML models into consumer-facing products.
  • Architect: Design scalable REST APIs and clean PostgreSQL schemas.
  • Build Culture: Work directly with founders to define the engineering roadmap and coding standards.

Must-Haves

  • Python Master: Deep familiarity with Django & DRF.
  • Frontend Pro: Solid React.js experience (Redux/Zustand).
  • Mobile Ready: Experience with React Native (or a strong willingness to learn it fast).
  • Database Skills: Comfortable with PostgreSQL and complex queries.

Bonus Points

  • 1-2 Years Experience: Proven history of shipping full-stack applications.
  • Experience with WebSockets/Real-time communication.
  • Deployment knowledge (Docker, AWS/GCP, CI/CD).

The Mission

Cosmium AI is building the next generation of conversational Speech AI. We are solving the "latency problem" in voice bots—making AI sound human, instant, and intelligent. We are looking for a hacker-engineer who loves reading papers on Monday and shipping them to production by Friday.

What You'll Build

  • The Brain: Fine-tune and optimize LLMs for specific conversational tasks using instruction tuning, RAG and prompt engineering.
  • The Voice: Optimize STT and TTS models to reduce latency to <500ms.
  • The Pipeline: Build production-grade inference pipelines. You won't just train models; you will dockerize them, quantize them, and deploy them.

Must-Haves

  • Python Native: Expert in Python and libraries like PyTorch, NumPy, and Pandas.
  • Audio/NLP Experience: You have worked with HuggingFace Transformers, Librosa etc.
  • Engineering First: You know how to wrap a model in FastAPI/Flask and deploy it.

Bonus Points

  • Experience with WebRTC or streaming audio data.
  • Experience building with LangChain or LlamaIndex.
  • Published papers or active Kaggle/HuggingFace profile.
