Senior AI Fullstack Engineer

Etera is building the first AI-native corporate travel platform for the GCC market. We're a lean, high-conviction team replacing legacy TMCs with autonomous agents, real-time inventory, and a product experience that doesn't feel like it was designed in 2009. We're looking for a Senior AI Fullstack Engineer who can own the full stack from a smooth React Native mobile experience to TypeScript backend services and the AI/LLM layer that powers our multi-agent infrastructure.

Requirements

• 5+ years of professional fullstack engineering, with meaningful production work in mobile.
• Strong React Native track record — shipped apps, managed build pipelines, handled auth flows.
• TypeScript across the entire stack — mobile, backend, and agent tooling. This is non-negotiable.
• Hands-on with LLM APIs (Anthropic, OpenAI, or equivalent) — prompt engineering, tool/function calling, multi-turn context management.
• AI-augmented development: You use Claude Code, Codex, and similar agentic coding tools to achieve 10x engineering throughput.
• Mastra: Production experience with Mastra as an agent orchestration framework — workflows, tool definitions, agent memory, and inter-agent coordination patterns.
• LangChain: Solid working knowledge — chains, retrieval, tool use, memory backends, and integration into live backend services.
• Ability to operate as a full engineering team member — not a specialist silo.

Benefits

• Equity + Competitive Package — Meaningful equity stake. Competitive cash compensation. Built for the long term.
• High-Impact Market — GCC corporate travel is a $20B+ market with legacy infrastructure. You'll be building the replacement.
• Fast Cycles — No committee approvals. Ship, learn, iterate. If it breaks, fix it and ship again — better.
