• Collaborate closely with Threat Intelligence, Trust & Safety, Legal, and Product teams to understand goals and translate complex technical requirements into elegant, scalable solutions
• Improve system design and architecture to ensure stability, performance, and maintainability of both internal and customer-facing compliance and security services
• Analyze, communicate, and help prioritize complex technical concepts across teams
• Ongoing monitoring and maintenance of production services, including participation in on-call rotations
• Mentor and guide other developers in the team, helping to build collective technical expertise and promote best practices for writing well-tested, modular, and reusable code
