Job Title: Senior Full Stack Engineer - AI Products (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.
