Job Description - Python Backend Engineer (Microservices & APIs)

We are looking for a Senior Python Backend Engineer with strong experience in building scalable APIs, microservices, and data-driven backend systems. The ideal candidate will have deep expertise in Python, distributed systems, and performance optimisation, along with exposure to modern cloud-native architectures.

Key Responsibilities

  • Design, develop, and maintain scalable backend services and REST APIs using Python
  • Build microservices-based architectures for high-availability systems
  • Develop frameworks and reusable components for scalable, observable, and extensible applications
  • Handle large-scale data processing and transformation
  • Optimise system performance, including I/O operations, concurrency, and latency
  • Troubleshoot and resolve issues in distributed production environments
  • Ensure implementation of secure coding practices and API security standards
  • Collaborate across teams to deliver robust and production-ready systems

Technical Requirements (Must Have)

  • 7+ years of experience in Python backend development
  • Strong expertise in Python 3.x
  • Hands-on experience with Flask, FastAPI, or Django (REST APIs)
  • Solid understanding of:
    • Asynchronous programming (asyncio, multiprocessing)
    • Concurrency and parallel processing
  • Experience with microservices architecture
  • Strong database experience:
    • MongoDB (mandatory)
    • PostgreSQL or other relational databases
  • Experience in performance tuning, debugging, and monitoring
  • Familiarity with CI/CD pipelines and distributed systems troubleshooting

Security & Architecture

  • Strong understanding of microservices security
  • Hands-on experience with:
    • OAuth2
    • JWT-based authentication
    • API gateways
  • Knowledge of encryption, secure API design, and access control mechanisms
  • Experience building resilient and fault-tolerant systems

Good to Have

  • Experience with Docker and Kubernetes
  • Exposure to cloud platforms (AWS/Azure/GCP)
  • Experience integrating AI/ML models into backend systems
  • Knowledge of load balancing and system scaling strategies
  • Exposure to observability tools (logging, monitoring, tracing)

Domain Experience

  • Experience in Banking / Financial Services / Fintech preferred
  • Understanding of enterprise-grade systems and compliance standards

Soft Skills

  • Ability to drive technical decisions across teams
  • Strong ownership and accountability
  • Effective communication with technical and business stakeholders
  • Self-driven and capable of working in high-pressure environments

What This Role Really Demands

This is not a basic Python developer role. You are expected to:

  • Build production-grade systems, not just APIs
  • Understand system design, scaling, and failures
  • Work in complex distributed environments
  • Take ownership beyond coding
  • Competitive salary package
  • Health insurance
  • Annual leave as per UAE law
  • Opportunity to work on scalable enterprise systems
  • Career growth and learning opportunities
  • Collaborative engineering environment
  • Exposure to modern technologies and architectures
