Job description

Principal Software Engineer | Payments - Remote

I’m working with a payments SaaS business that was one of the first in the world to get PCI certification for software-only card payments on phones. Their patented tech is used by banks and acquirers in 28 countries. They’re going multi-cloud, and they need an engineer who treats infrastructure as software to lead it.

The role

This is engineering-first, not classic DevOps. You’ll help set the technical direction for the cloud platform and build it hands-on, and you’ll lead the infrastructure guild that sets standards across engineering. Mentoring is part of the job, but people management is optional. It’s a rare chance to design a platform like this largely from scratch.

What you’ll do

• Design a multi-cloud, multi-region platform targeting 99.999% availability
• Shape how the second cloud (GCP or AWS) is used alongside Azure
• Build automated deployment pipelines and lead the move to GitHub Actions
• Give developers on-demand ephemerally environments that clean themselves up
• Raise the team’s engineering and automation capability

What you’ll bring

• Production-quality code, ideally TypeScript or Python
• Infrastructure as code (Pulumi, or strong Terraform)
• The ability to reason about cloud architecture across providers
• The seniority to design and lead independently
• Payments, PCI DSS or regulated-environment experience is a strong plus
• Azure and AKS, with GCP or AWS coming in as the second cloud
• Pulumi (TypeScript or Python)
• Kubernetes, hardened for PCI DSS
• Azure DevOps moving to GitHub Actions
• Grafana
• Secrets and key management, including payment HSMs
• mTLS and zero-trust networking across clouds
