Senior Site Reliability Engineer

About Paxos 

Today’s financial infrastructure is archaic, expensive, inefficient and risky — supporting a system that leaves out more people than it lets in. So we’re rebuilding it.

We’re on a mission to open the world’s financial system to everyone by enabling the instant movement of any asset, any time, in a trustworthy way. For over a decade, we’ve built blockchain infrastructure that tokenizes, custodies, trades and settles assets for the world’s leading financial institutions, like PayPal, Venmo, Mastercard and Interactive Brokers. 

About the team 

The Site Reliability Engineering team at Paxos builds and maintains the secure cloud infrastructure that supports our mission to reshape the financial industry. They enhance engineering efficiency by creating standardized frameworks across product lines and develop self-service tools to streamline processes, making it easier for teams to get things done.

About the role

As a Senior Site Reliability Engineer, you’ll play a critical role in shaping and scaling the infrastructure that powers our platform.

What you’ll do 

• Design, build, and operate scalable, highly available cloud infrastructure primarily on AWS.
• Manage and evolve our Kubernetes environments to support the deployment and operation of modern, containerized applications.
• Define and implement Infrastructure as Code (IaC) using tools like Terraform, CDK, or Crossplane.
• Automate infrastructure provisioning, configuration, maintenance, and monitoring to reduce manual effort and improve reliability.
• Apply best practices around security, observability, and cost optimization across infrastructure and services.
• Manage and optimize database technologies, with a focus on Amazon RDS and Aurora.
• Partner with development teams to
• Investigate and resolve incidents, perform root cause analysis, and implement long-term fixes.
• Participate in on-call rotations and provide support for critical production systems.
• Contribute to SRE best practices, internal tooling, and team knowledge sharing.

About you

• 5+ years of experience in Site Reliability Engineering, DevOps, or related infrastructure roles.
• Deep expertise in public cloud platforms, especially AWS, with hands-on experience in services like EC2, S3, Lambda, CloudWatch, and IAM.
• Strong proficiency with Kubernetes and container orchestration — you’ve run production workloads and understand cluster management, scaling, and troubleshooting.
• Extensive experience with Infrastructure as Code (IaC) using tools such as Terraform, Pulumi, or Crossplane.
• Solid scripting or programming skills in languages like Python, Bash, or Go, with a strong focus on automation.
• Working knowledge of managed database services like Amazon RDS, Aurora, or PostgreSQL is a plus — but infrastructure is your main game.
