What You'll Do​

  • Develop high-performance backend services in Go and Python, writing clean, maintainable code for AI-driven workflows

  • Build and maintain APIs that seamlessly integrate with our AI microservices, handling complex data transformations

  • Write custom algorithms and data processing logic for non-standard workflows unique to our cutting-edge technology

  • Code efficient caching layers and session management using Redis for real-time user interactions

  • Build and maintain CI/CD pipelines for automated testing and deployment of backend services

  • Collaborate directly with ML engineers to write integration code that bridges AI model outputs with application logic

  • Work closely with technical artists and to develop APIs that deliver real-time rendering systems

  • Write data processing pipelines that handle large-scale, real-time avatar generation and manipulation

  • Code event-driven systems that respond dynamically to AI processing results and user interactions

  • Implement custom serialization, validation, and transformation logic for complex avatar data structures

At AvatarOS, we're not just writing standard web services – we're coding the future of authentic digital human interaction. As our Backend Engineer, you'll write the code that seamlessly bridges traditional backend development with cutting-edge AI technology, solving programming challenges that no one has tackled before. We value engineers who can work effectively with open source technologies and self-hosted solutions, bringing technical depth beyond managed cloud services.

Who you are

  • 4+ years of backend development experience with strong coding skills in Go and Python

  • Solid experience writing complex SQL queries and designing data models with relational databases such as PostgreSQL

  • Hands-on experience coding with Redis for caching implementation and data structure manipulation

  • Experience writing code for containerized applications and microservices communication

  • Hands-on experience with CI/CD pipeline development and DevOps automation practices

  • Strong programming experience integrating with AI/ML services and handling model outputs in code

  • Track record of writing performant code that handles complex, non-standard data processing workflows

  • Creative programmer who excels at coding solutions for novel technical challenges

  • Experience writing asynchronous code and implementing event-driven programming patterns

  • Strong coding practices around testing, debugging, and code optimization

  • Solid programming fundamentals with API development and service integration

Bonus Points:

  • Experience coding with gRPC, Redis pub/sub, or other high-performance communication and messaging protocols

  • Background writing real-time processing code or streaming data applications

  • Familiarity with open source tooling and self-hosted infrastructure solutions

  • Previous programming experience integrating traditional backend code with AI/ML model pipelines

  • Experience with concurrent programming and parallel processing implementations

  • Preference for candidates comfortable working with self-hosted solutions over reliance on big cloud providers
