• Own and improve the stability, performance, and scalability of tier 0 backend services that process billions of emails daily
• Collaborate with teams across R&D including Detection, Products, and Infrastructure to ensure Message Mailflow services meet the needs of the broader organization
• Participate in oncall rotations to maintain the reliability and uptime of mission-critical systems
• Drive continuous improvement by identifying opportunities to enhance system efficiency, reduce operational overhead, and increase reliability
• Raise the bar of engineering excellence, actively contributing to knowledge sharing within the team and participating in professional development activities

• Experience building features & components from scratch and operating them, balancing feature development work with operational tasks
• Open to following pre-established guidelines, coding practices, and conventions
• You’re growth-driven & looking to increase impact & responsibility over time
