How will you make an impact
- Set up strong monitoring and alerting on our CDN providers for our assets delivered
- Understand the performance in each region across all our CDN providers
- Make improvements to our CDN performance via configuration changes; E.g. know and make recommendations to caching strategies (TTL, header values, etc)
- Streamline collection of RUM metrics on the backend (we have around 1.6 billion activations of our JS per day, each of which sends RUM data back - currently we sample at < 1% but we’d like to scale this up)
- Speed up queries and report generation of RUM data using our query engine (currently we use Chartio.io that queries AWS RDS instances - we need to speed this up and are open to recommendations here to change our core stack)
- Respond to CDN emergencies as the primary point-of-contact
- Work with our customer success teams to triage CDN issues reported by customers
- Interface with our CDN vendors, negotiate contracts with them, reduce our costs, suggest new vendors
- Implement a CDN onboarding strategy where we test out new CDN vendors for a while before signing up a new contract with them
- Establish internal best practices around CDN usage and help product teams integrate our CDN into their architecture with the right caching strategy
- Keep up with developments in the CDN industry, seek out new ways to leverage them at Optimizely. Prototype their usage.

- You have a deep understanding of DNS, Anycast, global Internet routing architecture, major exchange points, CDN standards and diagnostics. E.g. you are able to observe, troubleshoot, and explain routing issues
- You can architect, implement and integrate tools, processes and appropriate homegrown solutions when necessary to monitor, balance and troubleshoot multiple CDNs on a global scale. E.g., you are able to use monitoring insights to drive changes in CDN configuration via APIs.
