Overview We are seeking a **Senior Backend Developer** to design and build scalable, high-performance systems for our products. The role focuses on writing production-ready applications in **Golang**, with expertise in distributed systems, concurrency, and optimizing for high throughput or low latency. The ideal candidate will have professional experience working with **AWS**, **Kubernetes**, and **Docker**, as well as expertise in message queue systems, particularly **Apache Pulsar** or similar platforms like **Kafka**. A strong background in blockchain technologies, including integrating with on-chain data and developing smart contracts using **Solidity**, is also required. ‍ Responsibilities * Develop and maintain production-grade backend applications in **Golang**, ensuring performance, scalability, and reliability. * Design and implement distributed systems with a focus on concurrency principles and fault tolerance. * Optimize backend services for high throughput, low latency, or both. * Integrate backend systems with blockchain networks and smart contracts. * Develop and maintain EVM-compatible smart contracts using **Solidity** and frameworks like **Hardhat**. * Manage and maintain infrastructure on **AWS**, with a focus on scalability and fault tolerance. * Deploy and maintain containerized applications using **Kubernetes** and **Docker**, including managing Kubernetes environments. * Work with **Apache Pulsar** to design and implement efficient data flow and messaging systems. Experience with **Kafka** is acceptable as an alternative. * Conduct code reviews, performance testing, and ensure adherence to best practices for security and scalability. Requirements * Proven experience developing production-ready applications in **Golang**. * Strong understanding of distributed systems, concurrency principles, and system design for high-load environments. * Professional experience with **AWS**, **Kubernetes**, and **Docker**, including maintaining Kubernetes environments. * Expertise with message queue systems, preferably **Apache Pulsar** or **Kafka**. * Proficiency in smart contract development on the EVM stack (e.g., **Solidity**, **Hardhat**). * Ability to design and optimize systems for large-scale data processing or high-frequency interactions. * Strong problem-solving skills and the ability to work independently in a fast-paced environment.
