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
  
  

Ready to join, hit the ground running, and clean up a complex, mission-critical backend?

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