About Us
Purpl is a Lebanon-focused digital wallet and remittance aggregator enabling seamless international transfers, local spending, and zero-fee USD cardless cash-outs. Licensed by the Central Bank of Lebanon, we connect global remittance providers (Remitly, Paysend, Ria and more) to a robust local infrastructure including Banque Libano-Française ATMs, direct BLF-to-wallet transfers, and an expanding agent network. Built on a cloud-native stack (AWS), Purpl serves 50,000+ users with products for consumers, businesses, and NGOs — delivering reliable, compliant, and high-performance financial services that expand access for millions.
Role Introduction
As a Senior Software Engineer (Backend) at Purpl, you will own and evolve the backend systems that move real money across borders and into people’s hands. You’ll design resilient APIs, optimize high-throughput payment flows, and harden systems for security and regulatory compliance. This is a hands-on leadership role where you’ll ship production-grade code, mentor engineers, collaborate with product and mobile teams, and influence architecture for a mission-critical fintech platform.
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.
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.
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.
If you’re a pragmatic backend engineer who cares about reliability, security, and building finance products that move people’s lives forward, we’d love to hear from you — join Purpl and help shape the future of payments in Lebanon and the region.
