We are seeking a Senior Machine Learning Engineer with deep expertise in Large Language Models (LLMs) and a strong background in applied Machine Learning. The ideal candidate will have built real-world production systems using LLMs and other ML models, and is capable of both development and client-facing collaboration. This is a hands-on technical role, requiring proven experience in delivering end-to-end GenAI solutions—not just prototypes.

Key Responsibilities:

• Design, develop, and deploy scalable ML/LLM-powered solutions using APIs (e.g. OpenAI, Gemini) and open-source models (e.g. LLaMA, Mistral).
• Fine-tune and adapt open-source LLMs for domain-specific use cases.
• Collaborate with cross-functional teams to integrate ML models into production systems.
• Solve complex NLP and ML problems using statistical, neural, or hybrid methods.
• Stay up to date with the latest advancements in GenAI and LLMs and apply them in practical scenarios.
• Engage with international teams and potentially support client-facing initiatives.

Requirements

• 1.5+ years of hands-on experience specifically with LLMs and GenAI (2+ preferred).
• Experience working with LLM APIs (e.g. OpenAI, Gemini) and open-source models (e.g. LLaMA, Mixtral).
• Proven track record of shipping production systems using LLMs—not just POCs.
• Experience fine-tuning LLMs or other open-source models.
• 4+ years of professional experience in Machine Learning (excluding internships or academic research).
• Strong NLP experience and familiarity with other areas of machine learning.
