About the Job

Requirements

  • Seven or more years of production engineering experience with recent hands-on reliability work.
  • Recent hands-on experience operating large-scale, fault-tolerant production systems on AWS or GCP.
  • Experience instrumenting production systems and governing service-level objectives and error budgets, rather than only installing dashboards.
  • Experience designing and executing failure experiments or disaster-recovery exercises with real failover validation.
  • Experience personally commanding serious SEV1/SEV2 incidents and driving root cause through to a systemic fix.
  • Demonstrated ownership of reliability outcomes with measurable results, such as availability, mean time to recovery, and error-budget adherence.
  • Evidence of multi-team technical leadership through standards, review, coaching, and mechanisms adopted beyond one service or team.

Responsibilities

  • Own end-to-end service-level objectives, error budgets, and production reliability outcomes, and represent reliability in architecture and scaling decisions.
  • Design and operate the observability stack so production services are fully instrumented, and define the standards platform and application teams follow.
  • Define and manage service-level objectives, run regular reviews with service owners, and drive corrective action when services consume error budgets unsafely.
  • Design and execute chaos experiments and validate that failure modes are covered by tested safeguards.
  • Define the incident process and serve as incident commander for the highest-severity incidents, including security incidents within the coverage window.
  • Establish and manage on-call rotations and escalation paths that provide continuous coverage with clean follow-the-sun handoffs.
  • Own disaster-recovery testing and failover validation against defined recovery objectives, and turn exercise findings into architectural and operational improvements.
  • Co-own cloud security posture management, runtime vulnerability detection, and configuration-compliance monitoring with DevSecOps.
  • Own reliability of stateful and streaming services, capacity planning and rightsizing, and autonomous agents for triage, predictive alerting, remediation, and self-healing.
  • Mentor engineers at different seniority levels, set standards adopted across teams, and align Architecture, DevSecOps, Cloud Operations, and Product Development behind a shared reliability roadmap.

Desired Qualifications

  • Production experience with cloud security posture management, runtime vulnerability detection, and workload protection across cloud and distributed environments.
  • Experience prioritizing risk using identity, workload, and exposure-path context to focus remediation on issues that materially increase attack likelihood and operational impact.
  • Experience with autonomous remediation and self-healing workflows powered by AIOps, including Amazon Bedrock Agent Core or equivalent agentic automation frameworks.
  • Hands-on experience in capacity management, resource rightsizing, efficiency engineering, and practical cost optimization based on FinOps principles.
  • Experience with load-balancing design and operations, including health-based failover, global traffic management, and performance optimization for highly available services.
  • Experience with AI traffic management via an LLM gateway, including request routing, policy enforcement, rate limiting, model fallback, latency optimization, cost controls, and observability for multi-model or multi-provider environments.
  • Ability to connect networking, security, and reliability considerations into cohesive platform design decisions that improve resilience, performance, and operability.

About the Company

IonQ

Trapped-ion quantum computing hardware and services

IonQ builds quantum computers using trapped-ion qubits and provides cloud access and on-premise systems (Forte and Tempo). It is expanding into quantum networking, secure communications, and sensing through acquisitions (Oxford Ionics, ID Quantique, Skyloom) and a SkyWater deal. Its customers include AWS Braket and the U.S. government, with revenue growth and a strong cash position to support expansion. The goal is to scale commercial quantum computing by creating a connected quantum ecosystem and broadening access beyond hardware.
