Senior Full Stack Engineer

Location: Belarus (BY)

Experience Level: Senior

Description

We are seeking an experienced Senior Full Stack Engineer to build and maintain high-performance, end-to-end features across our platform — from scalable backend microservices to rich, responsive user interfaces. You'll work on high-impact projects including real-time messaging systems, cloud infrastructure, and video streaming technology, collaborating across the stack to design, implement, and optimize new features that shape the future of our product.

Key Responsibilities:

• Design, develop, and maintain scalable microservices using NestJS or Go, and build the Angular frontends that consume them.
• Implement real-time communication features end-to-end, leveraging Kafka and MQTT for messaging and Sockets (native & Socket.IO) for low-latency interactions on both server and client.
• Build dynamic, high-performance UIs with Angular and TypeScript, applying reactive programming with RxJS and state management via Redux / NgRx.
• Translate Figma designs into intuitive, responsive, well-crafted UI components.
• Collaborate with DevOps to deploy and operate services across GCP and AWS environments.
• Work on video streaming solutions and integrate video protocols (e.g., RTMP, HLS, WebRTC) across delivery and playback.
• Implement and optimize APIs to ensure high availability, performance, and scalability.
• Contribute to architectural decisions, code reviews, and mentoring of junior engineers.
• Stay current with emerging technologies and integrate them into development workflows.

Requirements

Required Qualifications:

• 5+ years of full stack engineering experience, with strong depth on both backend and frontend.
• Backend: 3+ years with NestJS or GO; experience with microservices architecture and distributed systems.
• Frontend: strong proficiency in Angular and TypeScript, with in-depth knowledge of reactive programming / RxJS and Redux / NgRx state management.
• Proficiency with messaging systems such as Kafka or MQTT.
• Hands-on experience with Socket.IO or native socket programming for real-time applications.
• Experience with cloud platforms GCP and AWS.
• Solid understanding of containerization, with exposure to Kubernetes.
• Strong proficiency in JavaScript/TypeScript (Node.js); Go or Rust a plus.
• Familiarity with CI/CD pipelines and version control (Git).
• Experience with databases (SQL/NoSQL) and caching technologies (e.g., Redis).
• Proficient in interpreting and implementing UI/UX designs in Figma.

Preferred Qualifications:

• Experience with video streaming protocols (HLS, RTMP, WebRTC).
• Proficiency in Go or Rust for high-performance backend services.
• Experience with React.
• Experience in an agile environment with a strong emphasis on continuous improvement.
• Knowledge of security best practices for API design, data protection, and infrastructure.
