As an Infrastructure Engineer at Brain Co., you will build and scale the core platform that powers AI systems deployed inside some of the world’s most critical institutions — from government to energy and healthcare. Our platform runs in highly variable, high-stakes environments across cloud and on-prem settings, and your work will directly determine our reliability, performance, and ability to deliver for customers.

This is a foundational role on our Infrastructure/Platform team. You’ll work closely with engineering, AI/ML, and product to design scalable architectures, harden our environments, streamline deployments, and ensure the robustness required for enterprise and sovereign use cases.

What You’ll Work On:

Design and scale Kubernetes- and Terraform-based infrastructure across customer environments.
Define standards for networking, security, CI/CD, and multi-region deployments.
Build and maintain metrics, logging, tracing, dashboards, and SLOs.
Diagnose and improve performance across distributed systems and AI workloads.
Support high-performance inference, data pipelines, and large-scale backend services.
Ensure systems scale reliably under fast-growing and unpredictable workloads.
Partner with technical leaders on architecture and mentor engineers.

You Might Be a Great Fit If You…

Have 5+ years building large-scale backend or infra systems.
Know Kubernetes, Terraform, cloud networking, orchestration, and observability tools.
Bring strong distributed systems, performance, and incident-response experience
Work well with customers and teams to deliver reliable solutions.
Thrive in high-agency environments and set engineering standards.
Enjoy ambiguity, autonomy, and solving tough infra problems.
