Company Overview

Yakeey is a fast‑growing PropTech company headquartered in Casablanca, Morocco. Our mission is to simplify and accelerate real‑estate transactions by connecting buyers, sellers, renters and agents through a single digital platform. We operate a multi‑product portfolio—including a property marketplace, a credit application and processing platform and a valuation tool—built on a modern micro‑services architecture (Java/Spring Boot, Next.js, AWS, Kubernetes) and enriched with data and AI components.

Role Summary

As a Senior Backend Developer with T‑shaped skills, you will be responsible for a specific domain within Yakeey’s platform—either marketplace, credit or valuation—while ensuring that your work aligns with our overall architecture and collaborates effectively with other domain teams. You will demonstrate deep expertise in backend engineering (Java/Spring Boot, micro‑services, API design) and a broad understanding of adjacent areas (front‑end, data, DevOps, AI) to make informed design decisions that fit our one‑stop‑shop vision. Your focus on a single scope allows you to deliver high‑quality solutions within that domain, while maintaining architectural consistency across the platform.

Key Responsibilities

- Develop and maintain micro‑services in your assigned domain using Java/Spring Boot, following domain‑driven design and our established architectural standards.

- Design and expose APIs that integrate your domain’s services with other platform components, enabling seamless interoperability while adhering to our Model Context Protocol (MCP) where applicable.

- Ensure alignment with the integral architecture by basing design and implementation decisions on established patterns, guidelines and cross‑team agreements.

- Collaborate with adjacent teams (front‑end, data, DevOps, AI)



to understand dependencies and ensure that solutions in your domain integrate smoothly with their components.

- Apply your T‑shaped skills to understand how front‑end requirements, data flows and deployment considerations affect your domain, even as you focus deeply on backend development.

- Participate in architectural discussions to share insights from your domain and learn from other teams, contributing to a cohesive platform strategy.

- Implement best practices for code quality, testing, security and observability within your domain; participate in code reviews and continuous delivery.

- Mentor junior developers within your domain and encourage knowledge sharing across teams.
