We’re looking for a hands-on Senior AI Engineer (5–6 years) who can: Lead design and delivery of LLM & Document AI solutions end-to-end; Own AI services in production (APIs, pipelines, monitoring); Mentor a team of AI engineers and work directly with clients (US & India). This is a technical leadership role, not a pure manager role.

Job Responsibility:

  • Own the end-to-end lifecycle of AI features – from requirement understanding and solution design to development, deployment and monitoring
  • Build LLM/RAG-based solutions using vector databases (e.g., pgvector, FAISS, Chroma, OpenSearch) for search, QA, extraction and summarization over documents
  • Develop Document AI models / pipelines for OCR post-processing, entity/key–value extraction, classification and layout/table understanding
  • Deploy models as scalable APIs / microservices in cloud and on-prem environments using Python, Docker and CI/CD
  • Work directly with client stakeholders to refine requirements, present solutions and handle reviews / clarifications
  • Act as technical lead on 2–3 AI projects, guide the team on architecture, design and best practices
  • Mentor junior AI engineers via code reviews, design discussions and technical coaching
  • Design with security, privacy and cost in mind, especially for data-sensitive domains (BFSI, healthcare, legal, HR)

Requirements:

  • 5–6 years total experience, including 3+ years in AI / DL / NLP in production environments
  • Proven experience taking AI solutions from PoC to production
  • Strong in Python and core CS fundamentals (data structures, algorithms, clean code)
  • Hands-on with AI / NLP / LLMs – classification, NER, QA, summarization, document understanding
  • Experience with some of: PyTorch / TensorFlow / Hugging Face / LangChain / LlamaIndex / spaCy
  • Built and deployed RESTful ML services / APIs integrated with web or mobile applications
  • Worked with Docker and CI/CD pipelines
  • experience of AWS or GCP
  • Good SQL skills and experience with at least one RDBMS (PostgreSQL/MySQL)
  • Understanding of MLOps in production – monitoring, logging, model versioning, rollback, performance & cost optimisation
  • Excellent spoken and written English
  • Comfortable interacting with international clients and leading requirement / review calls
  • Strong ownership mindset and ability to lead and mentor junior engineers
  • Willingness to work with partial US time-zone overlaps for key meetings when required
  • Bachelor’s degree in Computer Science / Engineering / related field (mandatory)

Nice to have:

  • Experience in Logistics, Legal, HR/Recruitment, Healthcare, BFSI, Education, Engineering/Plant drawings
  • Exposure to Vision Transformers / advanced CV for document layout and OCR enhancement
  • Experience with experiment tracking tools (MLflow, DVC, WCB, etc.)
  • Exposure to security & compliance (CIS, SOC2, GDPR, HIPAA, PCI-DSS, ITIL)
  • Experience with on-prem / VPC-isolated deployments and data-sensitive environments
  • Knowledge of a systems language (Go / Rust / C++ / Scala) is a plus, not mandatory
  • Master’s degree is a plus
