Applied AI Engineer

About this role

A1 seeks an Applied AI Engineer to develop and deploy reliable AI features for a proactive smart assistant. You'll work across the full stack—from model behavior and prompt design to production systems—ensuring AI capabilities translate into real-world user value rather than just working in demos.

What you'll do

• Build and ship complete AI features from model selection through user experience
• Design and refine prompts, tools, memory systems, and agent workflows
• Convert raw model outputs into structured, predictable behaviors
• Debug and optimize across the full stack for latency, cost, and reliability
• Develop evaluation frameworks to measure real-world performance
• Collaborate with product and engineering to translate ambiguous problems into working systems

What they're looking for

• Machine learning fundamentals and neural network architectures
• Python and production-quality code
• LLM APIs and model fine-tuning/deployment experience
• PyTorch or JAX
• Vector databases and inference/serving (e.g., vLLM)
• Full-stack debugging across model, infrastructure, and product layers
• Problem-solving in ambiguous, fast-moving environments
• Shipping mindset with focus on iteration and continuous improvement
