Software Engineer

At Wallex, we build modern, scalable financial technology solutions. As a Senior Software Engineer, you will play a key role in designing, developing, and deploying high-performance backend services, focusing on Golang microservices and blockchain integration.

Responsiblities:

• Design and build scalable, maintainable microservices using Golang, driving system architecture, performance, and reliability improvements.
• Lead the integration of blockchain technologies into backend systems (focused on practical applications, not smart contract development).
• Collaborate with product managers, engineers, and designers to understand requirements and deliver business-critical features.
• Conduct and participate in code reviews, ensuring high code quality, scalability, and performance standards.
• Mentor junior engineers by sharing knowledge and providing technical guidance (informal mentorship; no formal management duties).
• Stay updated on backend and blockchain technology trends, proposing ways to continuously improve our systems.
• Troubleshoot production issues and work closely with DevOps to ensure smooth deployment and operation.

 Requirements:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related fields.
• 4+ years of professional experience as a backend software engineer, with strong hands-on expertise in Golang.
• Proven experience designing and building microservices architectures.
• Familiarity with blockchain concepts (e.g., distributed ledgers, cryptographic principles); experience integrating blockchain technologies (not necessarily developing smart contracts).
• Solid understanding of RESTful APIs, distributed systems, and cloud infrastructure.
• Hands-on experience with containerization tools like Docker and orchestration systems like Kubernetes.
• Familiarity with TypeScript and Node.js is a bonus, but not required.
• Strong problem-solving skills, debugging abilities, and an eagerness to learn.
