AI/ML Engineer: End-to-End ML & LLM Pipelines

Amex Hub; Islamabad; Sur place; PKR 1 800 000 - 3 600 000; Plein temps

Résumé du poste

Amex Hub in Islamabad is seeking an AI/ML Engineer to drive end-to-end ML/AI workstreams—from data prep and experimentation to production deployment and optimization. You will build and fine-tune NLP/LLM-based or computer vision models, design experiments, and develop RAG pipelines with embeddings and vector databases.

Collaboration with the AI/ML Lead and other engineers is essential as you stay current with new models and tools.

Qualifications

• 2–5 years hands-on experience building and training ML/AI models.
• Strong Python skills with PyTorch and/or TensorFlow, plus Scikit‑learn, NumPy, and Pandas.
• Solid grasp of ML fundamentals (supervised/unsupervised, overfitting, regularization, metrics) and deep learning concepts.
• Practical experience with LLMs/NLP and/or computer vision.
• Hands-on experience in at least two areas: fine-tuning pretrained models (LoRA/PEFT), building RAG pipelines with embeddings/vector databases, deploying models via APIs.

Responsabilités

• Own ML/AI workstreams end-to-end: data prep, experimentation, model training, evaluation and deployment.
• Build, train, and fine-tune models for NLP/LLM-based or computer vision use cases based on project needs.
• Design and run experiments, track metrics, and iterate based on results.
• Build and maintain RAG pipelines with embeddings and vector databases; assess suitable approaches (fine-tuning vs prompting vs RAG).
• Implement evaluation frameworks to validate model quality before/after deployment.
• Deploy models to production via APIs and cloud infrastructure with attention to latency and reliability.
• Debug data, training stability, performance issues across the ML pipeline; write clean, tested code and participate in reviews.
• Contribute to architecture discussions with AI/ML Lead and engineers while driving your own workstreams.
• Stay current with new models, techniques, and tools and bring relevant ones to the team.
