Pliant is a modular B2B payments platform that combines commercial card issuing, payment accounts, FX, and spend management in one system — adapting to existing setups rather than requiring customers to replace them. Fintechs and software platforms embed Pliant's payment infrastructure into their own products, from API-based Cards-as-a-Service to fully white-label solutions. A principal member of Visa and Mastercard, Pliant issues commercial cards in 13 currencies across 32 countries — under its own European e-money license and with licensed partners in the UK and US. to join our small platform team with a wide remit: owning the AWS infrastructure across multiple account types, the CI/CD pipelines for 20+ microservices, and the Lambda and ECS runtime that product teams deploy on. That covers Terraform modules, GitHub Actions pipelines, AWS account architecture, Lambda functions in Go and Python, and an active ECS to Kubernetes migration. You'll work directly with product engineers, understand where the friction is, and fix it. Write and maintain Terraform modules for AWS resources across dev, staging, production, and PCI scoped accounts, orchestrated through Spacelift. Own GitHub Actions pipelines for a fleet of Java and Kotlin microservices, including reusable workflows, matrix strategies, and cache behavior. Write Lambda functions in Go and Python for tasks like metrics collection, secret rotation, IAM authentication, and event dispatching. Set up Datadog monitors, dashboards, and SLOs that surface problems before a product engineer notices them. Own security and compliance controls: Manage IAM, KMS,



and access baselines that satisfy PCI DSS and SOC 2 without generating a support ticket every time a product team needs something. Use AI assisted coding tools daily: 5+ years in platform or infrastructure engineering, with meaningful time spent on production AWS at scale. Solid AWS

experience:
VPC design, IAM, ECS and EKS, Lambda, RDS. You know when the right answer is a managed service and when it isn't. Terraform proficiency: you write modules and have dealt with state migrations, drift, and broken remote states in a shared codebase. Kubernetes experience designing and running production workloads at scale. We're currently planning a migration from ECS to EKS, so this experience will be especially valuable. CI/CD experience with GitHub Actions at scale: reusable workflows, matrix strategies, and cache behavior. Datadog or equivalent, with monitors, dashboards, and SLOs as part of your definition of done. High Python proficiency: you can navigate our codebase and implement complex features for our internal customers. Experience with AWS IAM Roles Anywhere and certificate based authentication patterns. Fluency with AI assisted coding tools such as Claude Code or Cursor, used to ship features, not just review code. Familiarity with Go, enough to maintain and extend Lambda functions. Kafka cluster operations experience. By year one, you've shipped something that made the team's job smaller: a reliability improvement, a security control, or a self service capability that cut the ticket volume coming your way. Your choice of preferred OS, Windows or Mac Flexibility and possibility to work remotely
