About the Role

We’re building out a high-impact AI Platform team, and we’re looking for a Senior AI Engineer who builds models from scratch. This is not an LLM wrapper or API-only role — you’ll be responsible for architecting, training, and deploying production-grade AI/ML models that drive real business outcomes.

What You’ll Do

• Fine-tune open-weight foundation models for business applications
• Design and implement model training pipelines and evaluation workflows
• Own the ML lifecycle: data ingestion → training → evaluation → production deployment
• Collaborate with cross-functional engineering and product teams
• Contribute to scalable, secure, and high-performance AI systems

Must-Have Skills

• Python (intermediate–advanced) & PyTorch
• Hands-on experience designing, training, and deploying models from scratch
• Strong understanding of modern architectures (Transformers, diffusion models, recommender systems)
• Ability to translate business problems into modeling solutions
• Production ML experience, including pipelines and monitoring
