Full Stack Engineer, AI systems

About this role

A1 is seeking a Full Stack Engineer to build production-grade AI workflows that go beyond chat interfaces, handling multi-step reasoning, tool integration, and reliable task completion.

What you'll do

• Build end-to-end product features across frontend, backend, and AI integrations
• Design agent workflows that handle multi-step planning, tool use, and failure recovery
• Integrate LLMs, memory systems, and external tools into reliable production systems
• Optimize real-time AI interactions for streaming, partial results, and low latency
• Improve system reliability through observability, monitoring, and fallback mechanisms
• Collaborate with ML, backend, and product teams to ship features from concept to production

What they're looking for

• Full stack development (frontend and backend)
• System design and API architecture
• LLMs and AI-powered applications
• RAG systems or AI workflow design
• Next.js, Python, and Node.js
• SQL and NoSQL databases
• Docker and Kubernetes
• Pragmatic decision-making under ambiguity
