Staff Site Reliability Engineer, Platform Engineering

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 Mastercard, Visa, Robinhood, and PayPal.

As a Staff Site Reliability Engineer, you'll serve as a technical leader and architect within the Platform Engineering team - shaping the design, reliability, and scalability of Paxos' next-generation infrastructure platform.

You'll lead initiatives that define how Paxos builds, operates, and scales its cloud systems - from Infrastructure as Code and Kubernetes automation to observability and multi-region resilience. Your work will directly influence how we meet our commitments to customers, partners, and regulators by ensuring our platform is secure, compliant, and resilient by design.

• Architect, build, and operate resilient, scalable, and self-healing cloud infrastructure on AWS.
• Lead the evolution of Kubernetes and platform services to enable secure, automated, and multi-region operations.
• Define and enforce Infrastructure as Code (IaC) standards using Terraform, AWS CDK, and Crossplane to ensure consistency, security, and auditability.
• Drive automation across provisioning, configuration, and monitoring pipelines to reduce manual effort and operational risk.
• Establish and champion reliability, observability, and performance standards across Tier-1 services, ensuring alignment with regulatory and partner requirements .
• Partner with product engineering to enhance CI/CD velocity, service resilience, and visibility through shared tooling, SLOs, and platform patterns.
• Lead incident reviews, root-cause analyses, and systemic reliability improvements, embedding learnings into runbooks and design practices.
• Optimize cloud infrastructure for cost, performance, and fault tolerance, driving data-driven operational excellence.
• Mentor and upskill engineers, shaping architectural direction and influencing design decisions across multiple teams.
• Contribute to the technical strategy and roadmap for Paxos' infrastructure platform, aligning platform scalability with business growth and compliance objectives.

About you

• 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.
