Senior .NET Backend Contractor - Execution Specialist Contract Duration: 4-5 Mo

Location: Dubai (On-site preferred, Remote negotiable)
Contract Duration: 4–5 Months (Critical Delivery Phase)
Language: Arabic speaker preferred
Start Date: Immediate
Experience: 7+ years (must be fully operational on Day 1)

🔥 About the Role

Brixio is urgently seeking a high-performance backend contractor to join the final delivery phase of a large-scale digital transformation project for a major client in the UAE.

This is not a management or coordination role.
This is a hands-on, high-pressure contract for someone who can take ownership of unfinished backend modules, production issues, and integration blockers, and close them with precision, speed, and zero hand-holding.

The platform is already live across multiple channels (web, mobile, kiosk), built with a .NET Core microservice architecture, Kafka pipelines, and third-party integrations.

Requirements

🧨 Your Mission

• Own one task at a time — no overengineering, no overthinking.
• Finish what others started: microservices, scheduling modules, test booking, internal workflows.
• Stabilize QA-critical modules and backend integrations already in production.
• Decouple systems from existing client ERP and assist in finalizing service layers.
• Work directly with tech leads, QA, and DevOps to close deliverables with minimal noise.

🔧 Technical Must-Haves

• .NET Core (v6+) expert — must be able to drop in and deliver from Day 1.
• Deep understanding of microservices, asynchronous architecture, and Kafka.
• Proven track record of working in live production environments with legacy integration, API orchestration, and refactoring.
• Experience in modular systems — ability to work in isolated domains without reviewing the full project.
• Strong understanding of data flow, change tracking (CDC), and performance-critical service design.
• Familiar with Git standards, CI/CD, containerization (Docker), and observability tools.
• Database: Strong SQL (Oracle preferred), must handle complex joins, data consistency, and schema evolution.

🧠 Mindset & Execution

• You work clean, fast, and alone if needed.
• You don’t need to "understand the whole system" — you slice it, take your piece, and ship it.
• You will be judged by speed and quality of execution, not process.
• You ask questions only when needed, and you don’t wait for perfection.

Send your GitHub, LinkedIn, and 3 shipped projects (no fluff). Interviews will be technical, direct, and fast.
