Design and integrate RESTful APIs with third-party platforms (ZRA, payment gateways, etc.).

Write efficient, secure, and scalable code with a focus on high concurrency.

Collaborate with other developers and stakeholders to deliver reliable backend systems.

Use tools like Postman, Swagger, or OpenAPI for testing and documenting your APIs.

Who We’re Looking For:

Strong experience in Java 11+ and Spring Boot 3
Excellent command of SQL with hands-on MariaDB/MySQL experience
Comfortable writing raw queries and optimizing for high concurrency
Deep understanding of REST APIs and third-party integrations
Experience with multi-tenant architecture and schema management
Familiarity with Postman, Swagger, or OpenAPI
Bonus: Experience with Vue.js is a plus for occasional UI hooks and testing

What We Offer:
Competitive salary

High-impact projects at scale (real users, real data, real results)

A backend-first culture where your work powers entire platforms

Mentorship and room to grow as a backend specialist

Flexible work setup – remote options available
