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

Strong communication and collaboration skills

You might be a great fit if you

Default to automation over manual processes

See repetitive work and immediately want to eliminate it

Think in terms of systems, failure modes, and long-term scalability

Care about building infrastructure that other engineers can use safely and confidently

Enjoy working in a small team with high ownership and impact

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

We're a lean team, so your impact will be felt immediately, and opportunities will grow as the company scales up. If this all sounds like a good fit for you, why not join us?
