Do you want to be known as the developer who contributed to the fusion of existing software and AI? Are you eager to work with the most cutting-edge technologies available? Would you like to join a startup and grow with it into international success? If so, read on!

This company was founded in July 2023 and is comprised of a team of experts who strongly believe in the power of AI in conjunction with existing software. Their mission is simple: to connect advanced AI models like ChatGPT with everyday software that businesses use, such as Booking. They aim for AI software not only to comprehend inquiries but also to genuinely perform complex tasks, such as booking an entire trip for a user. This is what lies ahead for all of us.

What makes our client unique is that they've set a speed record within the AI community, securing significant funding in just 2 weeks. The funding was achieved in record time due to their compelling concept and the involvement of major European and American investors. By the end of September, they will launch their first MVP (Minimum Viable Product), which will be commercially deployable. This is your opportunity to be part of this revolutionary project.

As a Senior Full-Stack Developer at our client's company, you will be the key figure in shaping the structure of their APIs. This role goes beyond regular development; you must have a deep understanding of system testing. Managing system tests is crucial because the software must seamlessly integrate into customers' software.

The software will enable any company to build its own AI version of software, much like a company can currently build a mobile version of its software. This means even complex tasks can be executed effortlessly by Large Language Models (LLMs) like ChatGPT. In this role, you will work closely with the CTO to refine and expand the MVP to make the software suitable for enterprise environments.
