• Infrastructure-as-Code (IaC): Standardize and evolve infrastructure using IaC, focusing on consistency, repeatability, and auditability.

• Observability: Drive a comprehensive observability stack (metrics, logs, traces) for production health, performance, and resource tracking across Fusion environments and the core platform.

• Tooling: Develop automation tools and internal platforms that reduce manual operations and accelerate our cloud management processes.

Requirements

• Experience: 7+ years of professional experience in an SRE, DevOps, or Infrastructure Engineering role, ideally in a high-growth SaaS environment.

• SRE/Platform Proficiency: Expert-level proficiency managing, scaling, and optimizing production environments.

• Adaptability & Initiative: Proven ability to navigate technical ambiguity, proactively defining and solving novel infrastructure problems alongside the engineering team.

• Customer Focus: A relentless curiosity about how our customers use the Fusion Cloud platform to drive continuous improvement in stability, scalability, and user experience.

• IaC & Scripting Proficiency: Expert proficiency with Infrastructure-as-Code (Terraform) and scripting (TypeScript, Python, Go, or Bash).

Bonus

• Experience building out infrastructure for VPC deployments.
