Etera Technologies FZCO

<div>About Etera
Etera is building the first AI-native corporate travel platform for the GCC market &mdash; designed from the ground up for how businesses in the region actually operate. 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.
The Role
We're looking for a Senior AI Fullstack Engineer who can own the full stack &mdash; from a smooth React Native mobile experience to TypeScript backend services and the AI/LLM layer that powers our multi-agent infrastructure (OPUS Prime). If you think in systems, ship fast, and find it natural to reason about both user-facing product and underlying model behavior, this role was built for you.
What You'll Own<ul><li>
Mobile-first product: Build and maintain Etera's React Native app (Expo/TypeScript) &mdash; booking flows, real-time updates, multilingual UX (Arabic/English).</li><li>
Backend services: Design and extend our TypeScript backend, including booking APIs, supplier integrations (PKfare, RateHawk, Hotelbeds), and webhook orchestration.</li><li>
LLM integration: Work directly with Claude (Anthropic API) and our multi-agent OPUS Prime system &mdash; building, tuning, and extending AI pipelines for travel intent detection, QA, and automated engineering reports.</li><li>
End-to-end delivery: Take features from spec to production. Own the full lifecycle &mdash; architecture, implementation, testing, deployment.</li><li>
Infra &amp; reliability: Firebase Auth (OTP, Apple, Google), EAS Build/TestFlight pipelines, and CI/CD hygiene across the stack.</li><li>
Code quality: Participate in security audits and peer review within a small, high-trust engineering team.</li></ul> 
Tech Stack
Frontend / Mobile: React Native + Expo, TypeScript, Firebase Auth (OTP, Apple, Google), EAS Build / TestFlight, Native iOS/Android context.
Backend / AI: TypeScript (end-to-end), Anthropic API / Claude, Mastra (agent orchestration framework), LangChain (chains, tools, memory), Zeabur / cloud deployment, REST + Webhook integrations.
You've Built and Run Agent Teams. Plural.
This is not a role for someone who has experimented with LLMs on side projects. We're looking for engineers who have designed, shipped, and actively maintained multi-agent systems &mdash; and who understand what it takes to keep them reliable in production.<ul><li>
Proven agent team ownership: You have built one or more autonomous agent teams from scratch &mdash; defined their scope, wired their tools, managed inter-agent communication, and own their continued operation.</li><li>
Self-validating mindset: You don't hand off agent output blindly. You act as the primary validation layer for the systems you build &mdash; designing evaluation criteria, catching failure modes, and iterating on agent behavior based on real output quality.</li><li>
Cross-domain fluency: Your agents have touched multiple domains &mdash; not just one narrow use case. You can reason about agent behavior across booking logic, data quality, QA pipelines, code review, or content generation without needing a specialist in each area.</li><li>
Maintenance discipline: You have a track record of keeping agent systems healthy over time &mdash; prompt drift, tool failures, context window management, regression testing. Not just shipping and moving on.</li><li>
Full-stack integration: You connect agent teams to real product surfaces &mdash; not just notebooks or internal tools. Your work shows up in APIs, mobile interfaces, or backend workflows that real users depend on.</li></ul> 

Requirements 
<ul><li>
5+ years of professional fullstack engineering, with meaningful production work in mobile.</li><li>
Strong React Native track record &mdash; shipped apps, managed build pipelines, handled auth flows.</li><li>
TypeScript across the entire stack &mdash; mobile, backend, and agent tooling. This is non-negotiable.</li><li>
Hands-on with LLM APIs (Anthropic, OpenAI, or equivalent) &mdash; prompt engineering, tool/function calling, multi-turn context management.</li><li>
AI-augmented development: You use Claude Code, Codex, and similar agentic coding tools to achieve 10x engineering throughput. You know how to create, configure, and orchestrate coding agents &mdash; not just prompt them &mdash; and you treat them as force multipliers across your daily workflow.</li><li>
Mastra: Production experience with Mastra as an agent orchestration framework &mdash; workflows, tool definitions, agent memory, and inter-agent coordination patterns.</li><li>
LangChain: Solid working knowledge &mdash; chains, retrieval, tool use, memory backends, and integration into live backend services. Not just tutorials.</li><li>
Ability to operate as a full engineering team member &mdash; not a specialist silo. You ship frontend, backend, and AI layers as needed, and you hold the full picture in your head simultaneously.</li><li>
Comfort in a lean startup environment: fast cycles, high ownership, minimal process overhead.</li><li>
Strong written English. Arabic or German is a genuine plus given our markets.</li></ul>
Bonus Points<ul><li>
Prior work with GDS/NDC/travel supplier APIs (Amadeus, Sabre, PKfare, RateHawk).</li><li>
Experience building multi-agent AI systems or autonomous workflow orchestration.</li><li>
Experience with Voice AI agents (Ultravox, Vapi, ElevenLabs, or equivalent) &mdash; building or integrating automated voice calling systems.</li><li>
Familiarity with DIFC / UAE regulatory context for SaaS or fintech products.</li><li>
Background in security auditing or static code analysis tooling.</li></ul> 

Benefits 
<ul><li>
Greenfield Ownership &mdash; You won't inherit a decade of technical debt. You'll shape the architecture from the ground up.</li><li>
Real AI Work &mdash; Not AI as a buzzword. Actual multi-agent systems in production, with full access to our OPUS Prime infrastructure.</li><li>
Remote-First &mdash; Work from anywhere. Async-friendly culture with a team distributed across Europe and the Gulf.</li><li>
Equity + Competitive Package &mdash; Meaningful equity stake. Competitive cash compensation. Built for the long term.</li><li>
High-Impact Market &mdash; GCC corporate travel is a $20B+ market with legacy infrastructure. You'll be building the replacement.</li><li>
Fast Cycles &mdash; No committee approvals. Ship, learn, iterate. If it breaks, fix it and ship again &mdash; better.</li></ul></div>
