Founding Lead Machine Learning Engineer

Transform Language Models Into Real-world, High-impact Product Experiences.
A1 is a self-funded AI group, operating in full stealth. We're building a new global consumer AI application focused on an important but underexplored use case.
You will shape the core technical direction of A1 - model selection, training strategy, infrastructure, and long-term architecture. This is a founding technical role: your decisions will define our model stack, our data strategy, and our product capabilities for years ahead.
You won't just fine-tune models - you'll design systems: training pipelines, evaluation frameworks, inference stacks, and scalable deployment architectures. You will have full autonomy to experiment with frontier models (LLaMA, Mistral, Qwen, Claude-compatible architectures) and build new approaches where existing ones fall short.
Why This Role Matters
You are creating the intelligence layer of A1's first product, defining how it understands, reasons, and interacts wi...
