Technical Lead, Machine Learning at Bjakcareer

About the Role

A1 is building a proactive AI system that understands context across conversations, plans actions, and carries work forward over time. You will be responsible for turning research direction into working, production-grade ML systems, owning the execution layer of A1’s intelligence.

Key Responsibilities

• →Build and own end-to-end ML pipelines spanning data, training, evaluation, inference, and deployment
• →Fine-tune and adapt models using state-of-the-art methods such as LoRA, QLoRA, SFT, DPO, and distillation
• →Architect and operate scalable inference systems, balancing latency, cost, and reliability
• →Design and maintain data systems for high-quality synthetic and real-world training data
• →Implement evaluation pipelines covering performance, robustness, safety, and bias
• →Own production deployment, including GPU optimization, memory efficiency, latency reduction, and scaling policies
• →Collaborate closely with application engineering to integrate ML systems into backend, mobile, and desktop products
• →Make pragmatic trade-offs and ship improvements quickly, learning from real usage
• →Work under real production constraints: latency, cost, reliability, and safety
