Location: Remote or Hyderabad (preferred)

Type: Full-time / Tech co founder - equity only - NO SALARY TILL WE RAISE seed funding

Level: Mid to Senior (6–8 years experience)

Role Overview

We're looking for a backend engineer who loves building clean, scalable APIs, but also has curiosity (and basic competence) around natural language processing and intelligent systems.

What You'll Do

  • Build and maintain scalable APIs using FastAPI
  • Design relational schemas using PostgreSQL for users, matches, profiles, and chat
  • Implement and optimize real-time chat systems (using WebSockets or Firebase)
  • Integrate LLMs via APIs (OpenAI, Claude, Cohere) to extract emotional & safety insights from chats
  • Build and iterate text classification pipelines (toxicity detection, vibe scoring, ghosting patterns)
  • Implement work/profile verification systems (e.g., email OTPs, LinkedIn screenshot check)
  • Collaborate on matchmaking logic, including Operation Manmadha (our AI-enhanced compatibility algorithm)
  • Build admin/moderation tools for trust, safety, and manual interventions

Skills & Experience Required

  • 6+ years of backend development experience (preferably with Python & FastAPI)
  • Deep understanding of REST API design, auth (JWT), and async architecture
  • Experience with PostgreSQL and Redis (or similar cache systems)
  • Familiarity with WebSockets or other real-time communication protocols
  • Exposure to OpenAI/Cohere APIs or similar — able to build LLM-based pipelines
  • Comfortable with prompt engineering, LLM outputs, and chaining logic
  • Experience writing modular, testable code and working in CI/CD environments

Nice-to-Have

  • Experience with Hugging Face Transformers, spaCy, scikit-learn, or PyTorch
  • Exposure to chat risk classifiers, toxicity detection, or sentiment analysis
  • Understanding of Gale-Shapley algorithm or other matchmaking logic
  • Knowledge of Firebase for presence/chat or file storage
  • Prior work in dating apps, mental health, or trust/safety tech

Traits We're Looking For

  • You think like a product builder, not just an API writer
  • You're excited about LLMs, user trust, and emotional tech
  • You write code that's easy to read, easy to test, and easy to scale
  • You're proactive — suggesting improvements and not waiting for specs
  • You care about making online dating safer, healthier, and more human

What We Offer

  • Chance to build India's most thoughtful dating platform
  • Work with a small, ambitious founding team with design, product, and film experience
  • Freedom to experiment with cutting-edge AI
  • A strong culture of autonomy, empathy, and no bullshit
  • Competitive pay + equity (for long-term hires)

Tell us:

  • One project you're proud of
  • Your comfort level with AI integration
  • Why Nova's mission matters
