Responsibilities
- Own reliability for CloudZero’s real-time ingestion path, including cross-team SLOs, failure modes, and resulting architectural changes.
- Define and enforce reliability standards for shared critical paths, including error-budget decisions before launch.
- Instrument systems and build observability so failures surface quickly and debugging is data-driven.
- Build production Python reliability tooling, including load generators, fault-injection harnesses, SLO libraries, deployment safety checks, services, automation, and agents.
- Design and maintain CloudFormation and SAM modules for reliable and cost-efficient cloud resources.
- Automate deployments, scaling, backups, limit changes, and other repetitive operational work.
- Evaluate and improve autonomous agents and make services legible to AI tooling through ownership and service metadata.
- Partner with product engineering on resilient service design, operational architecture reviews, deployment pipelines, shared templates, and SLO adoption.
- Optimize infrastructure for cost and performance and drive adoption of reliability practices across more than 40 engineers.
Requirements
- Strong production Python experience as a primary language, including ownership, testing, and maintenance at scale.
- Experience defining SLOs, including deliberate decisions about what not to alert on.
- Experience operating asynchronous, event-driven systems and reasoning about back-pressure, consumer lag, replay, poison messages, and partial failure using technologies such as Kafka, Kinesis, SQS, Pulsar, or Step Functions.
- At least 5 years building and operating distributed systems in AWS, with ownership of reliability outcomes.
- Practical Infrastructure as Code experience with CloudFormation and SAM, or transferable depth in Terraform or Pulumi.
- Hands-on experience instrumenting systems with monitoring tools such as Sumo Logic, Datadog, Prometheus, or Splunk.
- Proven ability to debug production issues under pressure and drive reliability or platform changes across teams without direct authority.
- Experience with or appetite for AI models and tooling such as Claude, Codex, or Gemini.
- Strong system design, documentation, communication, and cross-functional collaboration skills.
- Preferred experience includes chaos engineering, load testing, internal developer portals such as Cortex or Backstage, test automation, ephemeral test environments, GitHub Actions at scale, or LLM-backed tooling.
