About the team

Alloy’s Infrastructure Team is a small team (6 engineers) responsible for a large and growing infrastructure footprint: 15+ Kubernetes clusters, 100+ databases, dozens of services, and complex data organization.

Our challenge isn’t just scale—it’s making that scale reliable, secure, and operable with less manual work.

We’re looking for engineers who enjoy turning complex, fragile systems into automated, self-service platforms with strong safety guarantees.

What you'll be doing

Reporting to the Engineering Manager of Infrastructure, you'll:

• 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

Who 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
• Stro
