Infrastructure Engineer in London

NALA is building Payments for the Next Billion. Faster, smarter, and fairer transfers for everyone. Since 2022, we've grown our business 120x, grown the team from 9 to 150+, raised $50M+ from top-tier investors, and were named to the Forbes Fintech 50 in 2025 & 2026.

We operate two core products:

• NALA, our consumer app makes cross-border payments cheaper, faster and more reliable for the global diaspora, allowing users to send money from the UK, US and EU to Africa and Asia.
• Rafiki, our B2B payments infrastructure, is powering global payments.

Our team includes alumni from Wise, Stripe, Monzo, Revolut, and CashApp — operators who’ve scaled world-class products. We act with urgency, think deeply, and put our customers first always. At NALA, this isn’t just a job. It’s ownership, impact, and the chance to change global payments forever.

Your mission is to build and scale the infrastructure that powers fast, reliable and secure global payments at NALA. You’ll help create resilient systems, developer platforms and cloud foundations that enable engineering teams to ship confidently at high velocity.

Your Responsibilities in this Role

• Build and improve the cloud infrastructure powering NALA and Rafiki, ensuring high availability, scalability and security across our systems.
• Improve developer experience through automation, self-serve tooling and infrastructure-as-code practices that increase engineering velocity.
• Own and evolve our observability, incident response and reliability practices to minimise downtime and improve system performance.
• Partner closely with product and engineering teams to support new services, migrations and platform improvements across the business.
• Strengthen our security posture by implementing best practices across networking, access controls, secrets management and production environments.
• Continuously improve CI/CD pipelines and deployment workflows to enable safe, fast and reliable releases.

Must-have requirements

• Experience building and operating production infrastructure on AWS (preferably), GCP or similar cloud platforms.
• Strong experience with Infrastructure as Code tools such as Terraform.
• Experience managing containerised workloads using ECS and Docker in production environments.
• Strong hands-on experience operating and scaling infrastructure components such as Kafka, Redis and managed relational databases like RDS.
• Strong understanding of networking, security, observability and distributed systems fundamentals.
• Experience improving CI/CD pipelines and deployment automation in fast-moving engineering teams.
• Comfortable debugging production issues and participating in incident response in high-availability environments.
• Clear communication skills and the ability to work closely with software engineers across multiple teams.

Nice to have requirements

• Experience working in fintech, payments or other regulated environments.
• Experience building internal developer platforms or self-serve infrastructure tooling.
• Experience supporting SOC2, ISO27001 or similar compliance initiatives.

Success in the role looks like

• 3-Month Metrics: Successfully onboarded into NALA’s infrastructure stack, deployment workflows and engineering processes. Delivered meaningful improvements to infrastructure reliability, deployment speed or observability tooling. Built strong working relationships with engineering teams and actively supported platform and production needs.
• 6-Month Metrics: Reduced operational bottlenecks through automation and infrastructure improvements that measurably improve developer velocity. Improved platform reliability, monitoring coverage and incident response processes across critical systems. Played a key role in scaling infrastructure to support increasing transaction volumes and product expansion.
