• Ensure highly availability, scalability, performance and security
• Drive engineering best practices, code quality, and design reviews
• Improve database performance, indexing strategies, query efficiency, and overall cost optimization
• Lead production incident investigations and root cause analysis
• Design and implement event-driven and asynchronous systems
• Work closely with DevOps on deployment, monitoring, and reliability
• Balance speed of delivery with long-term scalability and maintainability
• Mentor engineers and drive technical initiatives across teams

What You’ll Need

Technical Requirements (Must Have)

• Strong experience in Golang and building production systems
• Beginner to Intermediate knowledge in Java is a plus
• Deep understanding of concurrency, memory profiling, and performance optimization
• Experience designing RESTful APIs and system to system integrations
• Strong SQL knowledge and experience with PostgreSQL or similar RDBMS
• Experience with event streaming systems (e.g., Kafka) and realtime communication protocol (e.g. WebSockets)
• Hands-on experience debugging production issues
