Principal SRE; AI Enablement Platform

Position: Principal SRE (AI Enablement Platform)-2
Location: Poland

- 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
