You’ll collaborate closely with data scientists, data engineers, and business stakeholders to design, build, deploy, and improve machine learning models that drive measurable business outcomes.

What You’ll Do::
• Design, develop, train, and optimize ML models and AI solutions to solve complex business challenges.

What We’re Looking For::
• Proven experience in an AI/ML environment, with a track record of delivering impactful solutions.
• Experience with AWS and SageMaker for end-to-end ML development and deployment.
• Solid foundational understanding of modern AI/LLM models (e.g. BERT, GPT, Qwen, LLaMA or similar architectures).
• Hands-on expertise with traditional ML techniques (Supervised, Unsupervised, Semi-Supervised, and Reinforcement Learning, especially Deep Learning).
• Proficiency in Python for model development and implementation.
• Familiarity with LLM-based applications, including embeddings and advanced AI use cases.
• Strong communication skills, able to clearly explain technical concepts to both technical and non-technical stakeholders.
• Experience working effectively with distributed teams across time zones.
• Collaborative mindset with a focus on knowledge sharing and continuous growth.
• Fluent English.
