Contractors are typically hired for a set duration or until a project is completed and may work with multiple clients. They are expected to have expertise in various programming languages, frameworks, and databases to build and maintain complete web applications. This role often provides flexibility in work arrangements but requires strong problem-solving skills and adaptability to different tech stacks.

A Full Stack Software Developer on contract needs proficiency in both front-end and back-end technologies, such as JavaScript frameworks, server-side languages, and databases, along with a solid understanding of software development principles. Familiarity with tools like Git, containerization platforms (e.g., Docker), CI/CD pipelines, and cloud services, as well as relevant certifications, is often expected. Excellent problem-solving abilities, adaptability, and strong communication skills are essential for efficiently collaborating in dynamic environments and managing multiple project requirements. These skills enable success in delivering high-quality, scalable solutions within set deadlines while meeting client or organizational needs.

They may need to work independently while also collaborating with in-house developers, designers, and project managers to align on technical and business requirements. Managing tight deadlines, prioritizing tasks, and learning unfamiliar technologies or systems on the fly are common aspects of the role. Adapting quickly and maintaining clear communication are key to ensuring successful project delivery and ongoing client satisfaction.

Job description

About the job:

Contribute to developing cutting-edge AI systems, while enjoying the flexibility of remote work and setting your own schedule.

We are looking for an existing Coder (this is an opportunity to work with us as an independent contractor) to help advance AI development. 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. This job is only available to those in the US, Canada, UK, Ireland, Australia, and New Zealand. Those located outside of these countries will not see work or assessments available on our site at this time. This is an independent contractor position.
