LemFi (Series B) is building the go-to financial app for the Global South.


Moving to a new country shouldn’t mean starting from zero. That's why our team of 400+ spanning 20+ countries is building a financial ecosystem that helps immigrants stay connected to home, build stability, and create wealth regardless of where they are from or where they live.


What began as fast, affordable remittances is now evolving into a complete platform for multi-currency accounts, payments, credit, and long-term financial growth.


With millions of users across the globe, we process over $1B in monthly transactions to 30+ countries, proving that borders shouldn't limit financial opportunity.

The Role

You will be a Senior Platform Engineer at LemFi, responsible for designing, building, and evolving the cloud infrastructure that powers global money movement at scale.

Your mission is to create a secure, scalable, and cost-efficient AWS cloud platform that enables engineers to ship faster while meeting the operational and regulatory standards of a global fintech provider.

You won’t just maintain infrastructure — you’ll build a self-service internal cloud platform that improves reliability, strengthens security, and ensures our systems remain resilient as we process billions in transactions worldwide.

How You'll Contribute

  • Design and scale AWS infrastructure with a focus on reliability, security, and cost-efficiency

  • Build and maintain Infrastructure as Code (Terraform / CloudFormation) ensuring changes are auditable and reproducible

  • Improve observability (monitoring, logging, alerting, tracing) and strengthen SLO-driven reliability

  • Enhance CI/CD pipelines and contribute to our Internal Developer Platform

  • Support incident response, disaster recovery, and compliance (GDPR, PCI DSS, SOC2, DORA, ISO27001)

Who You Are

  • Ownership-driven — you take initiatives from design through production

  • Reliability-focused, with strong SRE principles

  • Security-conscious, understanding encryption, IAM, and compliance needs

  • Collaborative communicator who partners well across Engineering & Security

What You'll Bring

  • Strong experience with AWS (ECS, RDS, S3, ElastiCache, Networking)

  • Hands-on expertise in Terraform and/or CloudFormation (IaC)

  • Experience with Docker and containerised workloads

  • Solid understanding of cloud security, IAM, encryption & key management

  • Experience building and maintaining CI/CD pipelines (GitHub Actions, ArgoCD)

  • Familiarity with observability tools (e.g., New Relic)

  • Exposure to event-driven systems (Kafka, RabbitMQ) and distributed architectures

The Interview Process

  • Chat with a Talent Partner (30 mins)

  • Behaviours & Culture (45 mins)

  • Technical Interview (60 mins)

  • Final Interview (30 mins)
