BCI has an open position on our GenAI team working with our USA based client. The Sr. LLM Fine Tuning Engineer will join our offshore development team that is growing and there is a lot of new and exciting GenAI work to be completed. This is a full time remote position and must be able to work blended hours of EST / IST timings. *Please note this is a Sr level role focused 100% on leading LLM Fine tuning*

About the Role

We're looking for an LLM Fine Tuning Engineer to lead the customization and optimization of large language models for production use cases. This role owns the full fine-tuning lifecycle — from data preparation through training, evaluation, and deployment — working with open-weight models (e.g., Llama, Gemma) as well as proprietary/managed models (e.g., Google Gemini) where fine-tuning access is available. You'll be hands-on with real training runs at scale, not just prompt engineering, or API integration.

What You'll Do
- Fine-tune and adapt large language models (Llama, Gemma, and other open-weight models, plus managed options like Gemini where applicable)



for specific business use cases
- Design and execute full fine-tuning pipelines: dataset curation and cleaning, tokenization, training/eval splits, hyperparameter selection, and training runs (full fine-tune, LoRA/QLoRA, PEFT, RLHF/DPO as appropriate)
- Run and manage large-scale training jobs across multi-GPU / distributed environments
- Evaluate model performance using both automated benchmarks and human-in-the-loop review; iterate to close quality gaps
- Optimize models for production inference (quantization, distillation, latency/cost tradeoffs)
- Deploy fine-tuned models into production systems and monitor performance, drift, and degradation over time
- Collaborate with data, ML infrastructure, and product teams to define fine-tuning objectives and success metrics
- Stay current on the open-model landscape and evaluate new base models as candidates for fine-tuning
- Document methodology,
