Responsibilities

  • Design and implement AI‑driven backend systems using Node.js, creating APIs and services to support applications such as NLP, search, recommendation systems, and AI agents.
  • Build and integrate large language model (LLM) applications and AI agents using techniques such as retrieval‑augmented generation, prompt optimization, fine‑tuning, and reinforcement learning.
  • Develop end‑to‑end pipelines for data ingestion, feature engineering, model inference (batch and real‑time), and integration of AI‑driven workflows into production systems.
  • Collaborate with data scientists and machine learning engineers to ensure seamless integration of machine learning practices in Gen AI.
  • Optimize backend systems for latency, scalability, and cost, applying caching, load balancing, and other performance techniques to support high‑volume inference workloads.
  • Advocate for and implement MLOps best practices, including monitoring, logging, tracing, automated retraining, and model/prompt versioning to ensure robust and reliable AI systems.
  • Build reusable platforms or frameworks that streamline the deployment and monitoring of AI agents and machine learning models.
  • Lead the implementation of autonomous agents capable of multi‑step reasoning, decision‑making, and tool use in production environments.
  • Participate in design reviews, write high‑quality code, and contribute to documentation to ensure team‑wide efficiency and maintainability.
  • Mentor junior engineers and collaborate across disciplines to drive impactful solutions while aligning system design with business outcomes.
