• 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

• 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
• Excellent problem-solving and debugging skills, with a systems-thinking mindset
• Strong communicator who thrives in collaborative, remote-first teams
• Working knowledge of managed database services like Amazon RDS, Aurora, or PostgreSQL is a plus — but infrastructure is your main game
