Site Reliability Engineer

Hammerhead AI • Redwood City, CA

About The Position

We are seeking a Site Reliability Engineer to own the reliability, scalability, and operational excellence of Hammerhead's AI-driven power orchestration platform. Our software runs in production data centers around the world, where real-time decisions directly affect gigawatts of compute infrastructure. Availability, latency, and correctness are not negotiable.
You will work at the boundary between software and infrastructure, building the systems that deploy, monitor, and protect Hammerhead's platform in production. You will partner with engineering teams to establish SLOs, automate toil, accelerate releases, and ensure that when things go wrong, we know fast and recover faster.
This is a foundational SRE role. You will be the first dedicated hire in this function. You will set the standard for how Hammerhead runs software in production.
You will report to the Head of Engineering.

Requirements

• 4+ years of experience in site reliability engineering, DevOps, or platform/infrastructure engineering in production environments.
• Deep proficiency with Kubernetes and container orchestration in production, including cluster management, resource limits, autoscaling, and network policies.
• Strong infrastructure-as-code experience with Terraform, Pulumi, or equivalent. You manage cloud resources in code, not consoles.
• Hands-on experience with observability tools (Prometheus, Grafana, Datadog, OpenTelemetry, or equivalent) and building alerting that is actionable, not noisy.
• Experience using Claude Code (or similar) to develop and maintain secure, compliant, and automated infrastructure-as-code (IaC) workflows.
• Expertise in Python for writing automation scripts, internal tooling, and operational runbooks.
• Experience managing CI/CD pipelines (GitHub Actions, ArgoCD, or equivalent) and deployment strategies (blue/green, canary, rollback).
• Strong incident response instincts: you stay calm under pressure, communicate clearly during outages, and follow through on fixes after the fact.
• Comfortable working in environments with strict operational requirements: uptime SLAs, customer-facing commitments, and regulated or critical infrastructure.

Nice To Haves

• Experience deploying or operating software in industrial, energy, or data center environments, especially hybrid cloud/on-prem topologies.
• Familiarity with ML/AI system operations: managing model serving infrastructure, GPU workload scheduling, or real-time inference pipelines.
• Experience with advanced Kubernetes networking and security primitives.
• Background in chaos engineering, game day exercises, or formal reliability testing frameworks.
• Prior experience as the first or founding SRE at an early-stage company.

Responsibilities

• Own production reliability for Hammerhead's platform: define and enforce SLOs, SLAs, and error budgets across services, and drive resolution when they are breached.
• Build and maintain the observability stack: metrics, logging, distributed tracing, and alerting across cloud and on-prem deployment environments.
• Architect and manage CI/CD pipelines that enable fast, safe, and repeatable deployments to production data center environments.
• Automate operational toil: provisioning, configuration management, scaling, failover, and incident response workflows.
• Lead incident response: act as the primary on-call escalation, run blameless post-mortems, and drive systemic fixes that prevent recurrence.
• Partner with software and RL engineers to bake reliability into the development lifecycle: code reviews, deployment checklists, chaos testing, and load testing.
• Manage and evolve Hammerhead's cloud infrastructure (primarily AWS) and edge deployment infrastructure at customer data center sites.
• Establish security and compliance practices for production environments: secrets management, access controls, audit logging, and vulnerability remediation.
• Evaluate and introduce tooling that improves platform velocity and reliability, from container orchestration to infrastructure-as-code to incident management platforms.

Benefits

• Competitive base salary + meaningful equity in a high-growth, well-funded company
• Comprehensive health, dental, and vision insurance
• The opportunity to build Hammerhead's reliability function from the ground up and own it
• A collaborative, low-ego team of world-class engineers and researchers solving genuinely hard problems
• Work that matters: our platform reduces the energy footprint of AI at scale
