Overview of Opportunity
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.
Technical Requirements:
- 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.
Professional Attributes & Expectations:
- A "Re-write" Mindset: You are not intimidated by code that has undergone iterations and layers of 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.
Why Join Us?
You will be at the heart of the infrastructure that connects the world, solving hard problems in distributed computing and telecommunications. If you prefer deep technical challenges over routine feature updates, we want to hear from you.
