We Promise You An Inclusive Work Environment
### **AI/ML \& Generative AI Developer**
#### **Job Description**
==================
At Tecorb Technologies, we are building the future of intelligent systems by leveraging cutting\-edge AI/ML and Generative AI technologies.
We are looking for a driven and technically grounded developer with 1\-2 years of hands\-on experience to join our AI/ML \& Generative AI team. This role is suited for professionals who have moved beyond entry\-level exposure and are ready to take ownership of AI/ML pipelines, contribute to real\-world deployments, and grow into a senior AI engineer role. You will work on machine learning, deep learning, large language models (LLMs), and generative AI systems including GPT models, Transformers, diffusion models, and more.
If you connect dots, understand systems holistically, and are passionate about building intelligent applications — we want you.

- Perform data preprocessing, feature engineering, and dataset curation for training and evaluation
- Conduct model evaluation, benchmarking, error analysis, and iterative performance tuning
- Explore and implement reinforcement learning techniques (RLHF, reward modeling) to improve model interactions
- Build modular, scalable AI workflows using FastAPI, Docker, LangChain, and vector databases
- Stay current with AI research (arXiv, Hugging Face, OpenAI blogs) and prototype new ideas rapidly
- Write clear documentation for experiments, code, models, pipelines, and datasets
- *Required Skills \& Qualifications**
=====================================
