About DFNS

Finance is moving onchain. Stablecoins, tokenized deposits, securities and funds are changing how money and assets are issued, held and transferred. The destination is a financial system where any asset can be issued, moved and governed onchain with the controls regulated institutions require. That shift needs a new foundation. Just as core banking systems manage accounts and ledgers today, financial institutions need a platform to manage digital assets. DFNS is that platform. Today, we secure hundreds of billions of dollars in assets every month for more than 500 clients worldwide.

Why this role

Our platform processes transactions for banks and fintechs around the clock and it has run at 99.997% uptime since 2022 with zero breaches. That record is the product. You will own the infrastructure beneath it, from the Kubernetes clusters and pipelines that ship it to the AWS Nitro Enclaves that protect the signing path, across SaaS, hybrid and on-premise deployments at clients who run their own audits. In year one you will make every environment reproducible from code, turn observability into alerts that catch problems before clients do and carry the infrastructure controls through our SOC 2 and ISO 27001 audits.

What you’ll do

  • 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.

What you bring

Must-haves

  • A 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.

Nice-to-haves

  • Secure enclaves (AWS Nitro) or confidential computing.
  • HSMs and on-premise or hybrid deployments in regulated environments.
  • Blockchain nodes and networks in production.
  • Working knowledge of OpenShift, ECS, etc.
  • Working knowledge of GCP.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
