We provide flexible, project-based opportunities in data annotation and AI training. Unlike traditional full-time, part-time, or fixed-term roles, contributors work under open-ended contracts with no fixed schedules or contract lengths. You choose when to take on work based on project availability and what fits your routine. 

Our platform is built for self-directed work. You manage your own workflow, access learning resources as needed, and gain practical experience in the rapidly growing AI sector at your own pace. 

Whether you’re looking to earn additional income, gain hands-on exposure to AI systems, or take on intellectually engaging challenges in a fast-moving industry, Stellar offers the freedom to contribute to the development of next-generation AI technology on your own terms.  

Role Overview 

We are looking for experienced Software Engineers to support AI-focused projects across a wide range of technologies and programming languages, including JavaScript, Python, Go, C++, Ruby, and others. 

This is a flexible, open-ended, project-based contract role with no minimum time commitment or fixed working hours. Contributors select the projects they want to work on, decide when to work, and control how much they contribute—making this an ideal opportunity for professionals seeking autonomy and meaningful impact.
