Description

About aion

Aion is the enterprise AI platform, a full-stack solution for building, fine-tuning, and deploying AI at scale. Whether an organization is modernizing internal operations, launching AI-powered products, or transforming customer experiences, Aion takes them from concept to production on a single, unified platform.

We work differently than most AI companies: our teams deploy alongside our customers, turning production-ready AI into real business outcomes in weeks, not quarters.

We’re a fast-growing, VC-backed startup led by founders with a track record of successful exits. With teams across the US, UK, and India, we’re building the next generation of enterprise AI and we’re looking for exceptional people to help us scale.

Who You Are

You're an AI engineer passionate about building production-ready AI applications powered by Large Language Models, multimodal AI, and intelligent agents. You understand that building successful AI products goes beyond model development. It requires robust engineering, scalable infrastructure, thoughtful evaluation, and seamless integration into real-world business workflows.

You have experience building AI-powered applications using modern foundation models and frameworks. You're comfortable working across prompt engineering, retrieval systems, AI agents, model evaluation, APIs, and cloud infrastructure to deliver reliable, enterprise-grade AI solutions.

You're product-minded and understand how AI solutions create business value. You enjoy collaborating with customers, rapidly iterating on ideas, and transforming AI capabilities into production systems that solve meaningful problems.
