About the Position

seQura provides innovative, flexible, and easy-to-use payment technologies that help merchants acquire, convert, and retain more customers. We are a privately-owned fintech, currently expanding throughout southern Europe and Latin America, growing above 50% CAGR. We are looking for a Senior Platform Engineer to join our Platform team and help us build the platform that lets every engineer at seQura ship safely, quickly, and on their own.

About the Role 🤓

You'll work in a cloud-native AWS environment, in a regulated fintech, where security, compliance, and reliability are part of the product we offer to the rest of engineering. Our goal is to go much further: independent agents working across the whole scope of the platform, with engineers who decide what matters and own the outcome.

Responsibilities

• International expansion: Help seQura launch in multiple new markets, with the isolation, compliance, and reliability each one requires.
• AI-native platform: Move from AI that assists us to independent agents that operate across the whole scope of the platform, from infrastructure changes to support and incident response.
• Keeping up with open source in the AI era: Define new strategies to adopt, upgrade, and secure the open source software we depend on, now that it moves faster than ever.
• Scale without raising our baseline cost: Design the strategies that let the business keep growing while our base infrastructure cost stays flat.

Requirements

Must have:

• You've designed and operated highly available distributed systems in production, and you've lived through what happens when they fail: incidents, post-mortems, and the changes that made sure it didn't happen again.
• Proven experience scaling infrastructure at a global scale.
• Strong hands-on experience with AWS, Kubernetes, and Terraform in production.
• A product mindset: You put users and the business at the center of your decisions, and you can explain why one initiative matters more than another.
• Hands-on experience working with AI agents in your daily engineering work.
• Agency: You don't wait for a ticket. You spot the problem, decide it's worth solving, bring people along, and own it until it runs in production.
• Professional proficiency in English, both written and spoken.

Nice to have:

• Experience in fintech, payments, or other regulated environments (PCI DSS, DORA, or similar).
• Experience with Terragrunt, Atlantis, or GitOps workflows.
• Scripting or programming in Python, Go, or similar.
• Experience with Prometheus, Grafana, the Elastic stack, or Tempo.
• Experience building internal developer platforms or self-service tooling.
• Experience building your own AI agents, skills, or automations for engineering teams.
• Experience being part of an on-call rotation.
• Spanish.

Tech Stack 🛠️

AWS (multi-account), Kubernetes (EKS), Terragrunt, Atlantis, Helm, Jenkins, GitHub Actions, SOPS, Prometheus, Grafana, Thanos, Elastic, Tempo, Python, and AI coding agents such as Claude Code as part of our daily workflow.
