• Build the SRE Organization:
• Build and develop the team from its initial formation through full 24x7x365 production operations, including defining roles, interviewing and hiring team members, establishing career expectations, and developing future technical leaders.
• Mentor engineers and team leads, develop successors, and build an organization capable of operating effectively without depending on any single individual.
• Work with leadership to forecast staffing requirements as the platform grows from initial deployment through full production scale.
• Establish the Production Operating Model:
• Define the operating model for an SRE organization, including staffing and coverage model, escalation paths, on-call responsibilities, incident management, handoffs, production access, change management, and operational readiness requirements.
• Establish clear operational interfaces with Datacenter Operations, engineering teams, vendors, and other service owners.
• Establish and continuously improve production readiness standards, runbooks, operational procedures, failure-mode documentation, escalation processes, and incident response practices with a strong emphasis on automation and engineering over manual operational work.
• Develop training, cross-training, simulation, and production incident-response exercises to ensure the team can operate independently and confidently.
• Engineer Reliability Into the Platform:
• Embed with platform engineering teams during development to gain deep technical knowledge of the system and ensure reliability, serviceability, observability, and operational requirements are incorporated into the platform before production.
• Lead the development of SLOs, operational health indicators, alerting standards, incident severity definitions, and reliability reporting appropriate for a large-scale production infrastructure service.
• Build a culture in which recurring operational problems are engineered out through automation, improved observability, better platform design, and elimination of unnecessary toil.
• Ensure the SRE organization can rapidly diagnose and mitigate issues across compute, networking, storage, and supporting infrastructure.
• Develop strong technical depth within the team while maintaining access to specialist expertise in critical areas such as high-performance networking, storage, observability, and platform scheduling.
• Lead Production Operations:
• Lead or participate in major production incidents as necessary, particularly during platform development, launch, and early production.
• Establish a blameless post-incident review process focused on identifying systemic improvements and ensuring corrective actions are completed.
• Serve as the senior operational authority for the SRE organization and represent production reliability concerns in engineering and leadership discussions.

Required Skills and Experience

• Significant experience leading or building an SRE, Production Engineering, Infrastructure Reliability, or comparable function supporting large-scale, highly available production infrastructure.
• Experience taking a new or rapidly evolving platform through production readiness, launch, stabilization, and ongoing operation.
• Experience building and operating sustainable 24x7x365 production support or on-call organizations.
• Strong understanding of modern Site Reliability Engineering principles, including SLOs, incident management, observability, automation, toil reduction, capacity management, and production readiness.
• Strong incident leadership experience, including managing high-severity, multi-team production incidents under significant time pressure.
• A strong systems engineering background with a working understanding of Linux, networking, storage, distributed systems, automation, and production infrastructure.
• Ability to operate effectively at both the leadership and hands-on technical levels, moving comfortably between organizational design, architecture discussions, troubleshooting, and incident response.
• Demonstrated ability to lead, hire, mentor, develop, and retain a growing team of strong technical engineers at various levels of capability
• Strong judgment regarding when to solve an immediate operational problem and when to invest in eliminating the underlying failure mode.
• Strong written and verbal communication skills, particularly during incidents and when communicating technical risk to senior leadership.
• Ability to manage conflicting priorities under a pressured environment

Desired but Not Required

Candidates are not expected to have experience in all the areas below. Experience in several would be particularly valuable:

• High-performance networking technologies such as InfiniBand, RDMA, RoCE, or large-scale Ethernet fabrics.
• Large-scale parallel or distributed storage systems.
• Workload schedulers and orchestration platforms such as Kubernetes, Slurm, or comparable systems.
• Production observability and service-level monitoring for complex distributed infrastructure.
• Custom or early-generation hardware, firmware, or environments where hardware and software are developed concurrently.
• Operational relationships and escalation processes involving datacenter operations and infrastructure/hardware/networking vendors.
• Rapid capacity expansion, datacenter migration, or transitions between temporary and permanent production environments.

What Success Looks Like

• The SRE organization is staffed, trained and capable of supporting the platform through production launch and subsequent growth.
• Production readiness, observability, incident management and operational engineering practices are embedded into how the platform is developed and operated.
• The team has the technical depth, automation and operating discipline to resolve most production issues independently, with leadership escalation reserved for genuinely exceptional events.
