Principal SRE (DE & Agentic Tooling)

- Join ABC Fitness, the leading technology provider for the fitness industry! What You’ll Do • Architect and evolve core platform capabilities for reliability, including execution environments, CI/CD systems, and validation pipelines that support high-throughput, machine-assisted change. • Design and implement fast, ephemeral, and strictly isolated execution environments where generated work can be built, tested, and safely discarded at scale. • Transform CI/CD into a validation system by embedding automated verification (tests, integration harnesses, canarying, rollback signals) into promotion decisions. • Build production-like validation environments that allow realistic system behavior testing without impacting live systems. • Establish deep observability patterns for autonomous workflows, including tracing what ran, what failed, why, and what it cost across agents, tools, and orchestration layers. • Define and implement guardrails-as-code, including access controls, policy enforcement, cost protections, and auditability for platform usage. • Design for reliability from day one, including scalability, fault tolerance, performance optimization, and operational resilience. • Lead technical design reviews and influence platform and infrastructure decisions across engineering teams. • Define and document reusable infrastructure patterns, platform standards, and reference implementations that create a consistent paved path for teams. What This Is Not • Not a ticket queue or generic support role. • Not incremental-only ops without ownership of architecture and adoption. • Not “just Kubernetes admin”—Kubernetes is one layer in a broader platform problem. What You’ll Need • Typically 10+ years of experience in Site Reliability Engineering, Infrastructure Engineering, or Platform Engineering. • Deep experience designing and operating distributed systems at scale, including cloud platforms (e.g., AWS), Kubernetes, and infrastructure-as-code. • Strong expertise in reliability engineering practices, including incident management, fault isolation, resiliency design, and system performance tuning. • Experience building and operating CI/CD systems, test harnesses, and automated validation frameworks. • Strong understanding of observability systems, including metrics, logging, tracing, and system-level debugging. • Demonstrated ability to define technical standards and influence multiple teams through architecture, design review, and strong engineering judgment. • Strong production mindset, with experience designing systems for scalability, availability, and operational efficiency. • Experience implementing secure, multi-tenant infrastructure with strong isolation, IAM, and secrets management practices. • Excellent cross-functional collaboration skills. • Growth mindset and One Team orientation. And It’s Great to Have • Experience supporting AI/LLM-powered systems in production, including understanding of latency, cost, and orchestration challenges. • Experience designing high-throughput ephemeral compute systems or sandboxed execution environments. • Experience building internal developer platforms or platform-as-a-product capabilities. • Familiarity with governance or regulated environments. • Experience with advanced validation systems such as canarying, chaos engineering, or automated rollback strategies. What Success Looks Like • Faster delivery through platform-enabled validation and automation. • Automated validation of changes before production, reducing reliance on manual review. • Platform standards adopted across teams as the default paved path. • Early detection of reliability issues through strong observability and validation systems. • Reduced infrastructure complexity so engineers can focus on product and policy. Why This Matters ABC Fitness is evolving toward an AI-native engineering model where automation, agents, and platform systems handle increasing portions of the software lifecycle. This role builds the foundation that enables scalable, trustworthy, and high-velocity software delivery across the organization. #LI-REMOTE If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us!
