Senior Systems Engineer

Fueled is a leading digital strategy, design, and engineering agency. As a Senior Systems Engineer at Fueled, you will design, deploy, and operate scalable infrastructure platforms, bringing expertise in modern infrastructure as code and automation to support various client environments.

Responsibilities:

• Own cloud infrastructure end-to-end: You will architect, deploy, and manage highly available environments across AWS and Azure using Terraform, Ansible, Helm, and CDK, and lead production Kubernetes workloads in EKS/AKS — including upgrades, networking, and autoscaling
• Serve as the Linux subject matter expert: You will own system builds, configure and troubleshoot core services like NGINX, MariaDB, and Redis, and drive performance, security, and reliability from the kernel up
• Operate the data and caching tier: You will run and scale MariaDB/Galera clusters alongside Redis, Memcached, and Elasticsearch, applying performance tuning and IaC-driven workflows to keep everything fast and resilient
• Engineer CI/CD and automation: You will build and tune pipelines in GitHub Actions, GitLab CI, and Azure DevOps, and replace repetitive operational work with robust Python and Bash scripting that accelerates developer velocity
• Lead observability, security, and performance: You will evolve monitoring across metrics, logs, and traces, harden infrastructure security, participate in incident response and the 24/7 on-call rotation, and lead load-testing efforts that drive measurable platform improvements

Requirements:

• Demonstrated senior-level experience in platform engineering or DevOps at scale or in multi-tenant environments
• Strong hands-on experience with AWS and Azure (multi-cloud preferred; GCP and Oracle Cloud a plus)
• Ability to set up, tune, troubleshoot, and harden Linux systems at a deep level
• Experience with Terraform, Ansible, Helm, or CDK projects from greenfield through long-term management
• Proven experience operating EKS/AKS — upgrades, networking, troubleshooting
• Management of production-grade NGINX, MariaDB/Galera, Redis/Memcached, and Elasticsearch
• Ability to write advanced Python and/or Bash
• Experience building and tuning CI/CD pipelines in GitHub Actions, GitLab, or similar tools
• Strong grasp of modern observability tooling and security best practices
• Excellent documentation skills
• Ability to work well with clients and bridge systems and application teams
• Availability for a 24/7 support rotation
