Backend Engineer - Node.js, Firestore and Algolia @ SquareOne

Project Description :

We’re looking for a skilled Mid-Senior Backend Engineer to join our team and play a key role in developing and enhancing our core domain responsible for delivering and managing all app content. Your first project will involve a focused migration effort, where you'll migrate schema, transform data, re-implement core rendering logic, and lay the foundation for an AI-ready, API-driven content delivery system.

The primary tasks will include evolving three key microservices : custom-cms, content-renderer, and content-api, and transitioning them to a standardized headless CMS with a clean, API-first interface. You’ll be handling complex migrations of relational Firestore data, re-implementing intricate logic, and ensuring the system is future-proof, leveraging AI capabilities.

Technologies / Skills :

• Must-Have : Node.js, TypeScript, Terraform, Algolia
• 5+ years of backend engineering experience with Node.js and TypeScript, following clean architecture principles.
• Strong expertise in relational databases (PostgreSQL / MySQL), particularly schema migration and transformation.
• Solid understanding of API design, caching, and high-performance content delivery.
• Comfort with asynchronous, event-driven systems (e.g., via Pub / Sub or webhooks).
• Experience with DevOps practices, CI / CD, infrastructure automation (Terraform, Docker).
• Practical experience with headless CMS platforms and their customization capabilities.
• Familiarity with cloud platforms such as GCP and Firestore, and experience integrating AI tools and pipelines.
• Experience in data migration, modernization, and optimizing high-volume, production-grade systems.
