Life Time is the nation's only Healthy Way of Life brand. As we transform our technology foundation, the Senior Director of Platform Engineering owns how Life Time builds, operates, and evolves its core platforms — cloud, data center, identity and access, storage, and the internal services that let every engineering team move faster. This leader is an engineer first and a product thinker by practice.

They treat internal engineering teams as customers and build platforms accordingly. Reliability is a feature. Self‑service is a design goal. The mandate is the shift from reactive operations to proactive, product‑driven engineering.

• Lead the design, build, and operation of cloud, data center, and hybrid infrastructure on engineering‑first principles.
• Drive IaC adoption so infrastructure is version‑controlled, peer‑reviewed, and deployed through automated pipelines — manual change is the exception.
• Own capacity planning, lifecycle management, and modernization of on‑prem data center and storage.
• Define the hybrid‑cloud strategy: what stays on‑prem, what moves, and the engineering path to get there.

• Establish SRE practices: SLOs/SLAs, error budgets, and reliability data that drives investment.
• Shift the model from incident response to failure prevention — observable, self‑healing platforms designed for graceful degradation.
• Champion blameless post‑mortems and engineering‑led root cause analysis.

• Own and modernize the enterprise identity platform: directory services, PAM, and SSO/federation.
• Partner with Security to reduce standing access, enforce least privilege, and enable secure self‑service.

• Run the internal developer platform as a product, with a prioritized backlog, adoption metrics, and developer satisfaction as a north‑star KPI.
• Give teams frictionless self‑service access to compute, secrets, and deployment tooling — the best platform interaction needs no ticket.

• Build and grow a high‑performing team — hiring for engineering depth, developing people, and fostering ownership.
• Manage operating and capital budgets transparently, framing investment in terms of reliability, velocity, and risk.
• Communicate strategy, risks, and progress to executive stakeholders in business terms.

• 15+ years in infrastructure or platform engineering, including 7+ leading engineering teams.
• Hands‑on fluency with IaC tooling (Terraform required; Ansible a plus).
• Demonstrated experience building or maturing an SRE or platform engineering function — not just running ops.
• Architectural‑level knowledge of AWS and/or Azure (networking, compute, identity, storage, cost).
• Experience owning an enterprise identity platform (Active Directory, Entra , Okta, or equivalent) and Zero Trust principles.
• Proven ability to shift team culture and practices toward engineering excellence.
• Bachelor's in Computer Science, Engineering, or related field, or equivalent practical experience.

• Building an internal developer platform or self‑service infrastructure layer.
• Git Ops tooling (ArgoCD, Flux).
• Kubernetes and container orchestration at scale.
• Observability stack ownership (Open Telemetry, Datadog, Grafana).
• Compliance frameworks: SOX, PCI, HIPAA.
• Consumer‑facing or multi‑site retail/hospitality technology.
