Job Title: Full Stack Architect (Claude Exp)
(Strong production engineering experience; track record of shipping systems end-to-end- experience is must)

Hacker-first engineer who ships production-quality AI features quickly; loves algorithms; pragmatic design, and clean code.

Summary:
We’re hiring a Senior Full‑Stack Engineer (AI-focused, hands-on) who prototypes quick, writes clean production code, and solves algorithmic problems simply and quickly. You’ll own feature delivery end-to-end: backend logic, model integration, and frontend UX — shipping high-impact features weekly.

What you’ll do:
- Build and ship core product features from prototype to production in days–weeks.
- Integrate and optimise ML/LLM pipelines (prompting, caching, latency/throughput tradeoffs).
- Design algorithms and data structures for real-time, scalable features.
- Debug and improve performance and reliability in production.
- Write concise design docs and clearly communicate tradeoffs.
- Mentor by code, not process: fast code reviews and technical leadership.

Must-have:




- 5+ years production engineering experience; track record of shipping systems end-to-end- Mandatory
- Excellent CS fundamentals: algorithms, data structures, complexity analysis.
- Strong backend (Python preferred) and modern frontend (React/TypeScript) experience.
- Experience integrating AI/ML services or models into products.
- Demonstrable examples of rapid prototypes, OSS contributions, contests, or technical projects.
- Excellent written and verbal communication: succinct design documents and PRs.

Nice-to-have:
- Experience with real-time systems, vector search, retrieval, or LLM optimisation.
- Familiarity with cloud infra, caching, and observability.
- Browser extension/web plugin experience.
- Startup experience and ability to wear multiple hats.

Basic Qualifications:
- BE / B.Tech candidates specialising in Computer Science or Artificial Intelligence with 4+ years of relevant work experience.
