Platform Infrastructure Engineer EU/UK remote (m/f/d)

We're looking for a Platform Infrastructure Engineer (m/f/d) 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. Every engineer at Pliant depends on what this team maintains.

You'll own one or more infra domains end to end: design, build, operate, on call. 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. You'll report to the Head of Platform Infrastructure.

• Own infra domains end to end: Take one or more domains from design through build, operations, and on call. You make the call, review the PRs, and answer the page.
• Run Infrastructure as Code: Write and maintain Terraform modules for AWS resources across dev, staging, production, and PCI scoped accounts, orchestrated through Spacelift.
• Maintain CI/CD at scale: Own GitHub Actions pipelines for a fleet of Java and Kotlin microservices, including reusable workflows, matrix strategies, and cache behavior.
• Build operational tooling: Write Lambda functions in Go and Python for tasks like metrics collection, secret rotation, IAM authentication, and event dispatching.
• Own observability: 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.
• Take part in on call: Join the rotation the team is currently shaping and own your incidents.
• Use AI assisted coding tools daily: Claude Code, Cursor, or something equivalent, both to ship features and to help peers get more out of them.

• 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. You're comfortable reading a plan output.
