Infrastructure & Security Lead Site Reliability Engineer (Infrastructure)

About the Role Alloy is seeking an Infrastructure & Security Lead Site Reliability Engineer to design and scale automated infrastructure for a large and growing footprint. As part of our Infrastructure Team, you’ll help reduce toil, improve reliability, and enable safe self-service for other engineers. This role blends hands-on engineering with architectural decisions to ensure scalable, secure operations across Kubernetes, databases, and services.

What You'll Do

• Design and build systems to automate infrastructure management at scale (provisioning, upgrades, migrations)
• Reduce operational toil by turning manual processes into reliable, repeatable workflows
• Build internal tooling and platforms that enable safe self-service changes for other engineers
• Improve the reliability and resilience of our infrastructure (Kubernetes, databases, services)
• Implement and evolve systems for deploying and running applications in Kubernetes
• Contribute to architecture decisions across infrastructure, reliability, and security
• Write and review production-quality code
• Participate in on-call rotations—but focus on building systems that prevent incidents, not just respond to them

What We're Looking For

• 10+ years of experience in infrastructure, SRE, or software engineering roles
• Strong software engineering skills—you build systems, not just scripts
• Experience managing production infrastructure at scale (cloud + containerized systems)
• Experience with Infrastructure as Code (e.g., Terraform)
• Experience running and troubleshooting distributed systems (Docker/Kubernetes)
• Experience with observability and debugging tools (Datadog, CloudWatch, ELK/EFK, etc.)
• Proficiency in at least one programming language (Python, Go, JavaScript, etc.)
• Experience participating in on-call rotations and improving systems based on incidents
• Strong communication and collaboration skills

Nice to Have

• Experience running Kubernetes in production at scale
• Deep familiarity with AWS
• Experience building internal platforms or developer tooling
• Background in distributed systems or large-scale data systems
