Senior Site Reliability Engineer

About the role

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.

Responsibilities

• 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
• 5+ 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

Requirements

• 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?
• This position has a salary range of $151,000 to $191,000.
• Benefits and Perks
• Unlimited PTO and flexible work policy
• Employee stock options
• Medical, dental, vision plans with HSA (monthly employer contribution) and FSA options
• 401k with 100% match up to 4% of annual employee compensation
• Eligible new parents receive 16 weeks of paid parental leave
• Home office stipend for new employees
• Annual Learning & Development annual stipend
• Well-being benefits include access to ClassPass, OneMedical, UrbanSitter, and Spring Health
