As a Mid Level Backend Developer, you may frequently encounter challenges related to maintaining code quality and ensuring scalability as applications grow. Managing database performance, optimizing API responses, and integrating with legacy systems are common tasks that require both technical skill and problem-solving ability.

What are Mid Level Backend Developers?

Mid Level Backend Developers are software engineers who specialize in developing and maintaining the server-side logic, databases, and APIs that power web and mobile applications. They usually have a few years of professional experience and are proficient in programming languages like Java, Python, Node.js, or Ruby. These developers are responsible for ensuring that data flows efficiently between the server and users, optimizing performance, and collaborating with front-end developers and other team members.

As a DataAnnotation’s coder, you’ll be part of a growing community of over 100,000 professionals — including front-end, back-end, full-stack, machine learning, and other engineers — who are driving real-world impact in AI development.

Our platform offers an engaging blend of flexibility and challenge: you’ll work closely with state-of-the-art AI models to take on programming tasks that include creating and solving challenging coding problems, building beautiful apps with rich functionality, and synthesizing insights through data analysis and visualization. Your work directly contributes to refining intelligent systems that learn, adapt, and evolve.

To get started, once you sign up for an account, you'll take a short assessment (this serves as our version of an interview). If you pass that assessment, you’ll receive an email confirmation, and paid work will become available to you through our platform.

Advantages of contracting with us:

  • You'll be able to choose which projects you want to work on and when
  • You work on your own schedule, on your own computer, from the comfort of your own home
  • Projects are paid hourly starting at $50-100+/hr, with bonus rates available on some projects

Responsibilities:

  • Give AI chatbots coding challenges and evaluate their outputs
  • Evaluate the quality produced by AI models for correctness and performance

Qualifications:

  • Fluency in English (native or bilingual level)
  • Detail-oriented
  • Experience with algorithms, data structures, and debugging workflows
  • A current, in progress, or completed Bachelor's is preferred but not required

Note:

Payment is made via PayPal. We will never ask for any money from you. PayPal will handle any currency conversions from USD.
