• Learn and apply modern software development practices, including AI-assisted development tools, testing frameworks, and collaborative engineering workflows.

• Participate in Agile development processes including sprint planning, standups, code reviews, and technical discussions.

• Tackle real-world business and engineering challenges, converting ambiguity into practical, maintainable technical solutions.

• Gain exposure to large-scale systems, cloud technologies, and production-grade software development practices within the ad-tech ecosystem.

We’re looking for someone with:

• Currently pursuing or recently completed a Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related technical field.

• Strong communication, collaboration, and learning mindset with the ability to work effectively in a fast-paced team environment.

• Curiosity, initiative, and a desire to continuously learn new technologies and solve challenging problems.

• Interest in emerging technologies such as AI-assisted development tools, machine learning, or large language models (LLMs).

• Solid understanding of computer science fundamentals such as data structure and algorithms.
  Fundamental grasp of software architecture and clean coding concepts is a major bonus.

• Experience with Java for backend development is a plus.

To help us get to know you better, include a two-sentence story in a section on your resume of a time you had to "figure something out" completely on your own. (Note: This can be absolutely anything; it doesn't need to be related to coding or tech!)
