About the role

The Senior Cloud Platform Engineer is the AWS architecture authority for Wyden's Run function — the most senior technical individual contributor in production operations. This role sits within Customer Success & Operations, reporting directly to the Head of Run, and is the engineering backbone on which every customer environment, deployment, and operational system depends.

This is not a pure operational support role and it is not a management role. It is a senior technical leadership position: you own the infrastructure architecture, you set the DevOps standards, and you build the systems that allow the broader Run team to operate with confidence. You will also recruit, onboard, and technically lead a junior SRE — defining what good looks like and building toward genuine team capability.

The Senior Cloud Platform Engineer will work in close daily proximity to the CTO and Head of Customer Success — involved in architectural reviews, compliance discussions, and operational governance decisions at a level that benefits significantly from being in the room. 

The deep AWS and DevOps execution that was previously concentrated in a single interim contractor is now formally owned by this role. Wyden's customer base is growing toward 20+ live environments. The infrastructure must scale with it — reliably, automatically.

 We will only consider candidates based in the Lisbon region.


Your responsibilities will include:

1.  AWS architecture & cloud infrastructure design

• Own the AWS architecture for all Wyden customer environments — multi-tenant and single-tenant — ensuring designs are scalable, secure, cost-efficient, and operationally maintainable
• Design and govern the infrastructure patterns that the Run team and junior SRE operate within: VPC design, EKS cluster architecture, Aurora/RDS configurations, IAM policies, networking (VPN, PrivateLink, Transit Gateway, Direct Connect)
• Lead infrastructure architectural reviews with the CTO, ensuring production decisions are technically sound and aligned with the platform roadmap
• Identify and address infrastructure risk proactively — before incidents occur, not in response to them
• Own AWS cost management: rightsizing, reserved instance strategy, architecture optimisations that reduce spend as the environment footprint grows

2.  Infrastructure as Code & DevOps automation

• Own all IaC for customer AWS deployments: design, write, test, and maintain Terraform and Terragrunt modules that are reusable, version-controlled, and reproducible across all environments
