1. Platform Reliability & Operations
2. Contribute, support and or lead the deployment, operation, and reliability of the block builder platform from Kubernetes clusters to bare-metal environments.
3. Maintain and scale distributed infrastructure spanning L1 and L2 environments, ensuring consistent performance under high-throughput and latency-sensitive workloads.
4. Drive observability, incident response, and performance optimization through modern SRE and DevOps practices.
5. Infrastructure Development & Automation
6. Build automation and tooling to simplify operations, improve developer experience, and reduce toil across our systems.
7. Design CI/CD workflows for high-assurance environments, including TEE-based systems and blockchain node infrastructure.
8. Contribute to the design of reproducible, secure environments across multiple clouds and hosting providers.
9. Cross-Functional Collaboration
10. Partner with backend, research, and protocol teams to support rollup infrastructure, MEV systems, and next-generation execution environments.
11. Participate in the envisioning, proofing, and deployment of new L2 infrastructure components and TEE-integrated products.
