Key Responsibilities

1. Research & Model Development

• Read, interpret, and replicate academic and applied research papers to develop innovative ML and deep learning models.
• Apply and fine-tune deep learning architectures including CNNs, RNNs, Transformers, and Siamese networks for search and recommendation systems.
• Implement ranking and relevance optimization techniques such as Learning to Rank, Two Towers, XGBoost, reranking, relevancy tuning, and collaborative filtering.
• Build and train embeddings for improving semantic understanding and personalization.

2. Thai Language NLP

• Develop NLP models tailored for the Thai language, addressing tokenization, fuzziness, and non-space segmentation challenges.
• Implement solutions for vector similarity, closest word matching, and context-aware text embeddings.

3. Deep Learning & GPU Training

• Design, train, and optimize deep learning models using TensorFlow or PyTorch.
• Efficiently utilize GPU infrastructure for large-scale model training and fine-tuning.
• Conduct hyperparameter tuning and experiment tracking for continuous model improvement.

4. Backend Integration

• Integrate ML and deep learning models into production systems via Python and JavaScript (Node.js) backends.
• Develop and maintain REST APIs for model inference and search functionality.
• Debug, fix, and merge backend issues using Git-based workflows.

5. Model Deployment & Operations

• Deploy and manage ML pipelines in production environments.
• Ensure models are scalable, low-latency, and fault-tolerant.
• Work closely with data engineers and backend developers to ensure seamless integration and monitoring.

6. Collaboration & Delivery

• Collaborate cross-functionally to deliver measurable improvements in search relevance and user engagement.
• Focus on hands-on, results-oriented solutions rather than purely theoretical models.

Requirements

1. Education

• Bachelor’s or Master’s degree in Computer Science, Data Science, AI, or a related field.

2. Experience

• Proven experience as a Machine Learning Engineer, Deep Learning Engineer, or Applied ML Developer.
• Prior experience in search, ranking, or recommendation systems is highly preferred.

3. Technical Skills

• Strong programming proficiency in Python and SQL.
• Experience with deep learning frameworks such as TensorFlow, PyTorch, or Keras.
• Knowledge of ML methods: CNNs, RNNs, Transformers, Siamese networks, XGBoost, and Learning to Rank.
• Familiarity with ML model deployment, GPU training, and backend integration.
• Backend experience in FastAPI, Flask, or Node.js.

4. Thai NLP (Good to Have)

• Ability to handle Thai tokenization, fuzziness, and non-segmented text.
• Familiarity with Thai word embeddings and NLP preprocessing.

5. Tools & Infrastructure

• Experience with Git, AWS (or other cloud platforms), Docker, and CI/CD pipelines.
• Ability to debug backend systems, fix issues, and merge pull requests efficiently.

6. Soft Skills

• Strong problem-solving and analytical mindset.
