Job description

About Etera

Etera is building the world’s first AI Concierge – a platform that helps users discover and book restaurants, hotels, experiences, and flights through intelligent, personalized interactions. We are a high‑velocity startup based in Dubai, operating with strong principles of ownership, speed, and technical rigor. Our backend systems are the backbone of the product: complex, data‑driven, AI‑aware, and built to scale from day one.

Role Overview

We are looking for a Senior Backend Engineer with deep experience in Python and TypeScript, working primarily with Bun and Elysia as our core runtime and framework. This role is about owning backend systems end‑to‑end – from API design and external integrations to data pipelines, personalization logic, and infrastructure awareness. You will be responsible for building and evolving complex backend workflows that understand user behavior, power AI‑driven personalization, and integrate multiple external services reliably at scale. This is a high‑ownership role for an engineer who has built real systems in production and thrives in startup environments.

Key Responsibilities

• Design, build, and own backend services using TypeScript, Bun, and Elysia.
• Develop and maintain supporting systems in Python for data processing, AI workflows, and pipelines.
• Architect and implement microservice‑based systems and inter‑service communication.
• Integrate and maintain external APIs (partners, vendors, AI providers, data sources).
• Build complex pipelines and workflows that analyze user behavior and drive personalized responses.
• Design backend logic that supports intelligent, adaptive, and context‑aware user experiences.
• Work with PostgreSQL for transactional data, analytics, and system state.
• Ensure backend systems are scalable, observable, and reliable.
• Collaborate closely with frontend and product teams to translate product requirements into robust backend solutions.
• Take ownership of services from design through deployment and iteration.
• Contribute to infrastructure discussions, including DevOps, deployment pipelines, and runtime environments.
• Maintain high code quality through testing, reviews, and strong Git‑based workflows.
• Own and shape the backend of a category‑defining AI product.
• Work on complex, real‑world systems that blend data, AI, and product logic.
• High autonomy and trust – you build it, you own it.
• Collaborate with a strong product and frontend team in a fast‑moving environment.
• Work from a modern Dubai office and be part of building something ambitious, technically deep, and globally impactful.

Qualifications

• 7+ years of professional backend engineering experience.
• Strong expertise in TypeScript for backend systems.
• Production experience with Bun and Elysia (or the ability to ramp up extremely quickly).
• Advanced Python experience for backend services, pipelines, or AI‑related workflows.
• Strong experience building and maintaining microservice architectures.
• Proven experience integrating external APIs and third‑party systems.
• Experience designing data pipelines, processing flows, and behavior‑driven systems.
• Solid understanding of PostgreSQL, schema design, and query optimization.
• Experience working in startup environments with fast iteration cycles.
• Strong ownership mindset – comfortable owning entire backend workflows and systems.
• Good understanding of DevOps concepts, infrastructure, and deployment pipelines (hands‑on or close collaboration).
• Proficient with Git and team‑based development workflows.
• Ability to collaborate deeply with product and frontend teams to build cohesive user experiences.

Nice to Have

• Experience with event‑driven systems, queues, or workflow orchestration.
• Familiarity with personalization engines, recommendation systems, or user modeling.
• Experience working alongside AI/LLM‑powered systems.
• Background in analytics, experimentation platforms, or behavioral tracking.
