About The Opportunity 

As a Senior Engineer on the Runtime Automation team, you will design, automate, and secure our core infrastructure, deployment platforms, and CI/CD ecosystems. Our team is responsible for managing our centralized Enterprise Logging Platform (Vector, Datadog, Splunk), engineering robust multi-cloud solutions across AWS and GCP, and driving automated deployment infrastructure via Jenkins and Spinnaker. In this role, you will focus deeply on containerization (Docker), Infrastructure as Code (IaC via Terraform and/or Pulumi), server image management (AMI), and low-level Linux operating system engineering, while ensuring top-tier observability and strict security across our mission-critical card payment environment. This is a high-impact position driving continuous reliability, deep system optimization, and automation across our entire technology ecosystem.

The Impact You Will Make

• Guide Technical Direction and Innovation: help define architectural strategies, introducing modern platform engineering practices, and driving complex technical decisions across infrastructure and CI/CD platforms.

• Coach and Mentor Engineers: Foster a culture of technical excellence by mentoring and coaching mid-level and junior engineers, conducting rigorous code and architecture reviews, and promoting continuous knowledge sharing.

• Scale Infrastructure as Code (IaC): Architect, maintain, and modernize declarative infrastructure across cloud environments using Terraform and/or Pulumi to drive reliability and self-service capabilities.

• Orchestrate Global CI/CD Infrastructure: Own, scale, and optimize high-throughput multi-cloud deployment pipelines using Jenkins and Spinnaker, ensuring fast, secure, and friction-free software delivery workflows.

• Secure and Standardize Payment Environments: Architect and harden our card payment infrastructure, ensuring the highest standards of data security, compliance, and proactive vulnerability mitigation.

• Optimize Infrastructure and Container Lifecycles: Own and scale the automated pipeline for AWS AMIs and Docker containers, using configuration management tools to ensure consistent, secure, and reliable image deployment workflows.

• Optimize Systems: Troubleshoot and optimize mission-critical infrastructure at scale, leveraging deep Linux internals knowledge and kernel-level tuning to maximize efficiency and stability.

• Advance Enterprise Logging and Observability: Scale and maintain our data ingestion workflows and centralized logging platform using Vector, Datadog, and Splunk, building robust dashboards and advanced alerting mechanisms to minimize downtime.

• Foster Operational Excellence: Participate in the team’s on-call rotation as an incident responder, leading postmortem discussions and writing automation scripts to eliminate repetitive operational toil.

What You Bring to the Table

• Technical Leadership and Mentorship: Proven experience or strong aptitude for helping guide technical direction, making sound architectural choices, and successfully coaching/mentoring other engineers.

• Infrastructure as Code (IaC) Expertise: Hands-on familiarity and engineering experience with modern IaC frameworks, specifically Terraform and/or Pulumi, to manage complex cloud resources.

• CI/CD and Deployment Expertise: Robust, hands-on familiarity with configuring, scaling, and troubleshooting enterprise CI/CD systems, specifical
