We at Unique AI are building a highly secure generative AI platform, tailored for the financial sector. Utilizing AI, LLM, agentic and Skills technologies, we aim to revolutionize the Financial industry with an AI Automated workforce. Our mission is to increase efficiency, improve alpha, reduce risk, and increase quality across everything we do. We offer an inclusive environment at Unique and we encourage all genders and all neuro-diversities to apply. We are now looking for a Product Engineer who thrives on solving real customer problems end-to-end — shaping what we build with Product and Design, then building and shipping it across frontend and backend.

Job Requirements

• Comfort with end-to-end ownership across frontend, backend, and everything in between
• Languages: Fluent in English (our working language)
• Communication: Strong communicator with ability to work with technical and business stakeholders, and to communicate clearly when navigating ambiguity
