Work reaches you through a backlog owned and ranked by the team's technical product owner. Requests from other teams are qualified, ranked, and specified by the team's technical product owner before they are assigned, so planned work arrives ready to start. You report to the Sr. Director of Platform Engineering, who sets vision, strategy, and the roadmap for Platform Engineering, and owns how the team's work gets done: technical approach, standards, assignment, and quality. This is an individual contributor role with no direct reports. We use AI throughout our work and want you to find uses for it we have not thought of. We also expect you to be able to do this job well if it were switched off tomorrow, because incident diagnosis and infrastructure design depend on your own judgment. Responsibilities * Build and operate the cloud infrastructure our platform runs on, and take each backlog item through to running in production, documented and monitored. Write infrastructure as code and hold it to the same standard as application code: reviewed, tested, and version controlled. * Build and improve the CI/CD pipelines our delivery teams ship through, and automate the manual steps in the delivery lifecycle. * Build parts of our internal developer platform (IDP), which Platform Engineering is developing now, as its items reach the backlog. * Build the monitoring, alerting, and dashboards that catch a problem before a customer reports it. Track consumption and cost against the throughput, concurrency, and headroom each service is sized for, and warn before a threshold is reached. * Join the on-call rotation, provide first response and root cause analysis for incidents raised through our customer support portal, and handle production support work that arrives through on-call or the backlog. During an incident, share what you know about recent changes, including your own, so the team can find the cause and address it quickly. * Test backup, archive, and disaster recovery by running restores and failovers against stated recovery point and recovery time objectives. * Keep our production and development environments secure and in line with our security policies, and work with security engineering on hardening, guardrails, and remediation. * Provision, refresh, and deploy environments through repeatable automation, including the non-production environments customers use for their own testing and acceptance. Keep them consistent, and keep production data out of non-production environments. * Build and maintain automated compliance and non-functional validation checks in our pipelines, along with the release gates that hold a change when the required control evidence is missing. * Produce the evidence that a control was applied and a requirement is met, in a form a customer's technology team or an auditor can review and sign off. * Work with our test automation team on performance, scalability, resilience, security, and vulnerability testing. Supply the environments, instrumentation, and platform knowledge, and help interpret the results. * Work with software engineering, QA, delivery, and customer implementation when a backlog item involves their systems, and mentor engineers earlier in their career. * Bring improvement ideas to the team's technical product owner, and if you think an item is ranked incorrectly, make your case with evidence., + Version control: Git + Cloud platforms: AWS, Google Cloud, including compute, networking, identity and access management, storage, and managed services + Containers and orchestration: Docker, Kubernetes or a managed equivalent + Infrastructure as code: Terraform with Terragrunt, CloudFormation, OpenTofu, Pulumi + CI/CD: CircleCI, GitHub Actions, GitLab CI/CD, Jenkins, Bamboo + Scripting: Python, Bash + Operating systems: Linux, UNIX + Monitoring and observability: Datadog, Splunk, Grafana, Prometheus, New Relic * Has designed and built a backend service with a REST API, in TypeScript, Python, or a comparable language, and run it in production. * Has written infrastructure as code modules, had them reviewed, and maintained them as requirements changed. * Has built CI/CD pipelines covering build, test, and deployment, including automated policy or control checks that stop a change that fails a requirement. * Can debug network problems such as those involving DNS, TLS, load balancing, or routing. * Can size infrastructure against a throughput and concurrency model with headroom above forecast peak. * Has been on call for a production system and led the initial response on a live incident through to a completed root cause analysis. * Has working knowledge of cloud security practice: least privilege, identity and access controls, secrets handling, encryption in transit and at rest, network segmentation, web application firewalls, security logging, audit trails for privileged access, and pipeline guardrails. * Has produced evidence that a third party accepted, such as an auditor, a regulator, or a customer's technology team. * Has proven a recovery by running a restore or a failover against stated recovery objectives. * Has worked alongside a test function on non-functional testing, whether performance, load, resilience, or security, and can build the environment and instrumentation a test needs. * Can write documentation in Markdown, which we use for our production documentation.
