About Aloja

Aloja.ai is building a dynamic pricing and demand intelligence platform for the tours, activities, and experiences industry. We are a highly technical team working with modern software architecture, cloud infrastructure, and AI-assisted development.

We are looking for a Full-Stack Software Engineer capable of working independently across backend services, Next.js applications, databases, and infrastructure.

This is a high-ownership role. We expect engineers to understand the systems they work with, investigate problems, make technical decisions, and take responsibility from diagnosis through production.

What you will do

You will build and maintain production systems using TypeScript, Python, Node.js, Next.js, PostgreSQL, AWS, and Kubernetes.

Your responsibilities will include:

Build and maintain backend services and APIs with TypeScript, Node.js, and Python.
Develop full-stack applications with Next.js.
Design and integrate REST and GraphQL APIs.
Work directly with PostgreSQL, SQL, relational models, and migrations.




Build and maintain microservices and asynchronous workflows.
Integrate external APIs and services.
Diagnose problems across applications, databases, containers, and infrastructure.
Write unit and integration tests.
Review and improve existing architecture.
Deploy and operate applications using Docker, Kubernetes, and AWS.
Use AI-assisted development tools throughout the engineering workflow.

You should be comfortable receiving a problem rather than a detailed implementation plan: exploring the system, finding evidence, identifying the root cause, and deciding what should change.
