Job summary

DFNS is seeking a Senior Infrastructure Engineer (US, remote first) to own the cloud infrastructure behind our onchain platform. You will manage AWS, Kubernetes, Terraform-based pipelines, and observability, ensuring security, scale, and reproducibility across SaaS, hybrid, and on-prem deployments for banking clients.

You will drive incident response, security controls, and audits while keeping services fast under real workloads.

Qualifications

• Record of designing and operating production infrastructure on AWS for systems where downtime or a breach has real consequences.
• Deep, hands-on Kubernetes and container experience, from cluster operations to workload hardening.
• Infrastructure as code with Terraform and CI/CD pipelines as the way you already work.
• Observability in practice (Datadog or equivalent) and experience running on-call and incident response.
• Working knowledge of infrastructure security and PKI fundamentals, including secrets, certificates and network segmentation.
• Scripting and systems programming (Python, Rust or TypeScript) to automate what you own.
• Experience administering and tuning SQL and NoSQL databases.

Responsibilities

• Design, build and run the cloud infrastructure behind the platform on AWS, with security and scale as first principles.
• Own the containerized platform (Docker, Kubernetes) and the way services are deployed, scaled and rolled back.
• Make every environment reproducible from code with Terraform and CI/CD, so a new region, a client environment or a recovery is a pipeline run rather than a project.
• Run observability end to end in Datadog (logs, metrics, traces) and turn it into alerting and on-call practice that catches problems before clients do.
• Configure and operate the AWS Nitro Enclaves and secure workloads that protect key material and signing.
• Keep Node.js services and the databases behind them fast and reliable under real financial workloads.
• Support client deployments and due diligence, including hybrid and on-premise models and the questions a bank’s infrastructure team will ask.
• Document what you build and carry the infrastructure controls through SOC 2 and ISO 27001 audits.
