What You'll Do

• Design, build, and maintain scalable backend services and RESTful APIs using Python, Django, and Django REST Framework to support wallets, payments, and payout flows.
• Drive service reliability and performance: profile, optimize, and scale systems on AWS (RDS, EC2, EKS, S3, ALB) while ensuring high availability and data consistency.
• Implement secure, auditable integrations with remittance partners, cardless ATM flows, and third-party providers, enforcing encryption, logging, and compliance controls.
• Lead CI/CD and deployment automation using Docker, Kubernetes (EKS), and infrastructure-as-code; manage safe rollouts, rollback strategies, and observability pipelines.
• Collaborate cross-functionally with product, mobile, and QA teams to define API contracts, deliver end-to-end features, and ensure production readiness for releases.
• Mentor engineers, perform code reviews, define engineering standards, and lead initiatives to improve testing, monitoring, and operational excellence.
• Investigate and resolve production incidents, conduct root-cause analysis, and implement preventive measures to reduce operational risk.

What You Bring

• 8+ years of professional backend engineering experience with strong recent experience in Python 3 and Django / Django REST Framework.
• Deep experience designing relational schemas and optimizing Postgres for high-throughput transactional workloads (indexes, partitioning, migrations).
• Proven experience deploying and operating services on AWS (RDS, EC2, EKS, S3, ALB/WAF) with attention to cloud security and cost optimization.
• Hands-on expertise with Docker, Kubernetes orchestration, CI/CD pipelines, and automated testing (unit, integration, end-to-end).
• Strong knowledge of application security, encryption at rest/in-transit, authentication protocols (OAuth2/JWT), and fintech compliance considerations.
• Experience with observability and incident management (logging, metrics, tracing — e.g., Sentry, Prometheus, Grafana) and conducting post-incident reviews.
• Excellent communication skills, experience mentoring teammates, and the ability to work effectively across distributed, cross-functional teams. Fluent English.

Nice to Have

• Experience with event-driven architectures and message brokers (Kafka, RabbitMQ, or similar).
• Familiarity with core banking integrations, Mambu, or payment rails used in remittance/payments flows.
• Exposure to mobile backend patterns, real-time features (WebSockets), or high-concurrency systems.
• Basic Arabic proficiency.
