Role Description We are seeking a high-caliber Senior Backend Engineer with a rare blend of legacy expertise and modern systems design. You will be tasked with bridging the gap between established Java infrastructures and high-performance Golang development. This role is not for the faint of heart. You will be responsible for deconstructing, re-architecting, and rewriting large, mission-critical codebases that power global telecommunications, ensuring they are scalable, resilient, and future-proof. This is a remote role. Key Responsibilities: - Legacy Transformation: Take ownership of large, complex Java codebases and strategically migrate towards high-performance Golang microservices. - Protocol Development: Design and maintain low-level communication interfaces involving SS7 (MAP) and DIAMETER protocols. - System Architecture: Build and optimize highly available resilient systems capable of handling multiple client connections. - Database Management: Design schemas and optimize queries for both MySQL and PostgreSQL to ensure data integrity and performance. Understand existing data structures and migrate them as appropriate. - Queue Management: Implement and manage robust job queues and asynchronous task frameworks to handle API traffic and background processing. Qualifications - Dual-Stack Understanding: Expert-level proficiency in both Java and Golang. You should be equally comfortable navigating existing code and writing equivalent high-concurrency Go routines. - Telecom Domain Knowledge: A deep, fundamental understanding of Signaling System No. 7 (SS7) and DIAMETER. You should be comfortable discussing the signaling stack from the MTP layers through to the application part. - Database Expertise: Advanced experience with MySQL and PostgreSQL, including performance tuning and distributed database patterns. - Task Orchestration and Notifications: Deep understanding of job queues and task management (e.g., RabbitMQ, Kafka, or custom-built Go workers). - API Capability: Comfortable with API models and specifying and writing endpoints to be used by adjacent applications. Requirements - A "Re-write" Mindset: You are not intimidated by code that has undergone iterations and layers with minimal documentation. You have the patience and skill to deconstruct complex logic and rebuild it to a superior standard. - High Agency: A drive to see tasks through to completion. You take pride in delivering robust, high-standard code. - Global Mobility: This role requires the ability to travel for extended periods to coordinate with global teams or oversee on-site deployments. - Flexibility: We offer flexible working hours to accommodate your peak productivity times, provided project milestones are met. Benefits - Competitive and comprehensive compensation packages. - Medical, dental, and vision insurance. - Life and disability insurance. - Retirement benefits. - Paid leave. - Tuition assistance and professional development. Salary Range $150,000 — $200,000 USD
