scale and grow. With the increase in infrastructure needs, we are committed to ensuring the highest level of security and performance for our web properties.

We expect this person to have familiarity with Google and/ or Azure cloud platforms, and familiarity with the .NET ecosystem.

- Collaborate with other SREs, developers, and our Product teams to develop and deploy solutions to identify, block, and manage bot traffic.
- Collaborate with other SREs, developers, and our Product teams to implement and maintain sophisticated anti-scraping technologies to protect our assets from unauthorized scraping efforts.
- Improve the observability of our systems to help identify issues and preemptively detect potential threats by iterating on our monitoring and alerting strategies.
- Reduce toil through software solutions by removing or automating manual tasks, steps, and workflows.
- Improve our security patching and compliance strategy for cloud solutions.
- Participate in our on-call rotation (typically 1 fortnight out of 4 months).
- Partner closely with your peers to accomplish goals within an agile software development lifecycle.
Our current ecosystem includes:
- Google Cloud Platform and/or Microsoft Azure
- Self-hosted infrastructure

Skills & Requirements
We’re looking for:
- In depth experience with CDN-level traffic analysis and management, in particular with Cloudflare.

- A strong practical understanding of software development lifecycle phases, from planning and development through production deployment and monitoring.
- Experience with Agile methodologies such as Scrum, Extreme Programming, or Kanban.
- Willingness to learn new technologies and adapt to changing priorities.
- Excellent problem-solving skills with the ability to respond quickly to incidents.
