AI Platform Engineer

About the role

We are forming our AI team with two foundational hires: an AI Platform Engineer (this role) and an AI Product Engineer. You’ll work directly with the VP of AI and to design, build, and ship intelligent features. This is a hands-on builder role: you’ll be delivering user-facing AI features from day one.

This is a rare opportunity to define the blueprint for how AI gets built at a fast-moving startup — and to see your work adopted by real-world, non-technical users.

What you’ll do

  • Design and build the systems that power core AI features: LLM service layers, prompt execution environments, evaluation pipelines, and logging infrastructure
  • Collaborate with platform and backend engineering teams to integrate AI into ReadyOn’s architecture
  • Create internal tools and abstractions to enable fast iteration on AI product features across the team
  • Own observability, performance, and correctness for AI workflows in production
  • Build automated and human-in-the-loop evals for AI outputs, including agent decision-making and tool use

More interested in designing AI-native features and crafting agent behaviors than building the underlying systems and infrastructure? We’re also hiring an AI Product Engineer.

Your background

  • You have strong backend or systems engineering experience and want to pivot into applied AI
  • You’ve explored LLM APIs or agent/LLM-related open source projects, maybe as part of a side project. Experience building AI systems in production is a plus but not required
  • You’ve built or maintained infrastructure that other teams depended on for core functionality
  • You’re fluent in Python and JavaScript/TypeScript, or have the experience to pick them up quickly

Why you’ll love this role

  • Massive impact: Your work will improve the lives of millions of workers and transform how huge enterprises operate
  • AI-native foundation: You’ll be building technology designed for AI from day one, not retrofitted into old tools
  • High-stakes deployments: You’ll see your work in action at stadiums, hotels, resorts, and hospitals across the world
  • Huge market: Even a 1% improvement in staffing efficiency can save billions
