Senior Software Engineer | AI & LLM Applications (Remote in Poland)

At Oversee, we are reimagining how corporate travel is managed.

Our cutting-edge technology and machine learning solutions replace the outdated, manual processes that slow companies down — unlocking cost savings, efficiency, and smarter decisions.

We bring together travel analytics and actionable insights, giving global enterprises a clear view of their spend and the tools to continuously improve their programs.

Now, we’re building the next frontier - AgentSee, our AI travel assistant that automates the complex workflows of travel agents. AgentSee uses LLMs and agentic reasoning to handle cancellations, exchanges, and traveler conversations across channels.

We’re growing fast, with exponential YoY revenue growth and partnerships with some of the world’s largest Fortune 500 companies.

If you are looking for a dynamic, fast-paced, and positive environment - and want to help solve a $17B global problem - Oversee is the place to build, grow, and make an impact.
