• Security and Compliance: Implement security best practices to protect the nodes and manage compliance for each chain
• Upgrades and Forks: Prepare for and execute network upgrades and forks, coordinating with the community and stakeholders
• Documentation: Maintain up-to-date documentation for each chain and communicate key updates to internal and external teams
• Collaboration: Be the internal point of contact for chain-specific expertise, working closely with the business, customer, dev, and modelling teams

• Strong understanding of blockchain protocols, security best practices, and performance optimization
• Proficiency in designing and implementing production-grade infrastructure and platform solutions, with a focus on automation and efficiency
