Employer: Ontada

Ontada is an oncology technology and insights business dedicated to transforming the fight against cancer. Part of McKesson Corporation, Ontada was founded on the core belief that precise insights – delivered exactly at the point of need – can save more patients’ lives. We connect the full patient journey by combining technologies used by The US Oncology Network and other community oncology providers with real-world data and research relied on by all top 15 global life sciences companies. Our work helps accelerate innovation and power the future of cancer care.

Ontada is an oncology data science and technology business. We specialize in real-world data and evidence generation that accelerates life science research, clinical technologies that support community providers with precise care, and provider engagement channels that enable education and insights.

We’re looking for a driven, enthusiastic technology leader to be part of the team that’s transforming the fight against cancer and improving the lives of patients. Backed by the strength of a Fortune 7 company.

Position Summary:

Ontada’s Site Reliability Engineering (SRE) team works with operations and development teams to ensure the monitoring and alerting of oncology-focused software systems. Additionally, the SRE team administers AWS for development teams, and shares CentOS administration responsibilities with an on-premises systems administration team. We apply software development principles to the automation of manual tasks.

Frequently used technologies:

  • We use Ansible playbooks for running tasks, provisioning servers, updating configuration, and installing software
  • Often, these playbooks are run from Groovy-based pipelines in Jenkins, which itself is used as a task scheduler (in addition to CI/CD)
  • If a task fails, or if a system is reporting abnormal metrics, Prometheus notices this and raises the issue to Alertmanager
  • Depending on how we’ve configured its PromQL-based matchers, Alertmanager may send this information on to PagerDuty, which notifies the SRE on-call
  • We use tools like CloudFormation, Troposphere, and Boto3 to provision AWS infrastructure
  • Some administration of Kubernetes instances is done in EKS and AKS
  • We use some miscellaneous such as: Internal utilities written in Python and Go, Wildfly server administration, a handful of assets in Azure, automation of Oracle RMAN

Working environment:

SREs communicate with each other and with other geographically dispersed teams through Slack, WebEx, Teams, and Outlook. Long-living documentation is stored in Confluence, JIRA, and often Markdown files in the repositories they describe. The main recurring meeting is a planning meeting once every two weeks. Other meetings are scheduled independently between an SRE and the teams (development/operational/business) that are working on specific tasks. The rest of your time is fairly flexible; we help each other out to ensure PagerDuty coverage.

Who we’re looking for:

You like to find the gaps in software systems and suggest fixes for them. You see unmonitored systems as a challenge to be brought up to a more transparent state. When you see a manual task being done, you naturally begin thinking of ways to automate it.

If you had worked here last week, you would have helped with:

  • Update a data export process to use different SQL tables and different file stores
  • Increase the frequency of Elasticsearch snapshots and their associated alerting
  • Add new AWS users to our SSO provider and configure their permissions
  • Research installation of a new Jenkins instance with the latest version
  • Code review Python for adding Slack notifications to a Django-based admin site
