Role overview

We are looking for an AI/ML Engineer with strong hands‑on experience in building, deploying, and optimizing modern AI systems – especially RAG pipelines, LLM‑powered applications, and autonomous/agentic AI workflows.

Key responsibilities

• Design and implement Retrieval‑Augmented Generation (RAG) systems and AI pipelines using vector databases and LLMs.
• Build and optimize AI/ML models for production, including training, fine‑tuning, quantization, and performance tuning.
• Work with AI agent frameworks and architectures to design autonomous, multi‑step workflows.
• Deploy and maintain production‑ready AI applications using MLOps best practices, CI/CD, Docker, and Kubernetes.
• Collaborate closely with product and engineering teams to rapidly prototype and ship AI‑driven features in an agile startup environment.
• Monitor, evaluate, and continuously improve model performance in real‑world usage.

Required skills and experience

• 1–4 years of hands‑on experience as an AI/ML Engineer.
• Strong Python skills and experience with ML/DL frameworks (TensorFlow, PyTorch, Scikit‑learn, Hugging Face Transformers).
• Practical experience with RAG systems, vector databases, or autonomous agents.
• Databases: PostgreSQL, MySQL, NoSQL, and vector DBs such as Pinecone, FAISS, Weaviate, or Qdrant.
• Experience with cloud platforms like AWS (S3, Lambda, RDS, SageMaker), Azure, or GCP.
• Strong understanding of LLM architectures (Transformers, Encoders/Decoders, Auto‑Encoders).
• Experience deploying AI systems with MLOps, CI/CD pipelines, Docker, and Kubernetes.
• Deep proficiency in AI model engineering: training, fine‑tuning, optimizing, and quantizing LLMs and other deep learning models.
• Experience with deep learning projects involving CNNs, GANs, Transformers, and encoder‑decoder architectures.
• Familiarity with AI/agentic frameworks such as LangChain, LlamaIndex, Haystack, LangGraph, AutoGen, CrewAI, Agno, or similar.
• Knowledge of custom fine‑tuning techniques: RLHF, LoRA, QLoRA, PEFT, etc.
• Comfortable using AI developer tools like Cursor, Codex, Copilot, Gemini in real workflows.
• Exposure to concepts such as MCP, Multi‑Agent Systems (MAS), Belief‑Desire‑Intention (BDI), and NLP pipelines.

Work conditions

• This is a full‑time onsite role from Monday to Saturday, 9:00 AM to 6:00 PM.
• During the probation period, candidates are required to use their own laptop; an office laptop will not be provided initially.

Culture and values

PurpleMerit is an equal opportunity employer. We value diversity, encourage fresh perspectives, and are committed to building an inclusive, supportive environment where engineers can do the best work of their careers.
