Senior Software Engineer

Posted 13 days ago

We offer flexible, project-based work in data annotation and AI training.

Unlike fixed full-time or part-time jobs or fixed-term contract work, annotators who work with us have open-ended contracts with no required schedule or set contract duration. You can choose to annotate when projects are available and when it fits your life.

Our platform is designed for self-service. You can control your workflow, access resources as needed, and build valuable experience in the growing AI industry at your own pace.

Whether you’re seeking supplemental income, hands-on experience with AI, or engaging challenges in a fast-growing field, Stellar gives you the flexibility to meaningfully contribute to creating the next generation of AI technology on your own terms.

We are seeking experienced Software Engineers to contribute to projects across a wide range of technologies and programming languages, including JavaScript, Python, Go, C++, Ruby, and more.
This is an open-ended contract opportunity, structured around project-based work with no set schedules or minimum time or task commitments. Contributors who work with us decide which available projects they'd like to work on, when they work, and how much they contribute, which makes it an excellent option for those seeking flexible and high-impact work.
In this role, you will help advance AI research by understanding complex systems, exploring large codebases, and developing approaches to verify the correctness of software behavior.
