Fullstack AI Engineer

Responsibilities and duties: Drive innovation by designing, building, and validating AI applications within a regulated banking environment. Objective of the assignment: Build and maintain full-stack AI applications, integrate OpenAI/Azure OpenAI capabilities, and translate business needs into working software. Practical examples In your first month, you will help improve a prototype that supports bankers in preparing for client interactions by making research and analysis faster, more consistent, and easier to validate with end users.

• This may include extending a FastAPI backend, improving a React / Next.js frontend, or integrating new OpenAI / Azure OpenAI capabilities into the application. The goal is to strengthen the prototype as a tool for validation with real users.

• You will build product features end-to-end: from backend APIs and LLM orchestration to frontend experiences that make AI capabilities intuitive and reliable.

• You will work closely with business stakeholders and engineers to translate product ideas into working software, while balancing speed, quality, compliance, and maintainability.

• Beyond project work, you will help improve the technical foundation of the application: code quality, testing, observability, security, and reusable full-stack patterns for AI-enabled products. Top responsibilities

• Build and maintain full-stack AI applications using Python / FastAPI on the backend and React / Next.js on the frontend

• Integrate OpenAI / Azure OpenAI capabilities into user-facing products in a secure and maintainable way

• Design and develop robust APIs, backend services, and frontend flows for AI-powered applications

• Assess technical feasibility of proposed AI solutions and advise the team on what is realistic

• Translate business needs into working software and iterative prototype improvements

• Contribute to security, reliability, and compliance of AI-enabled applications in a regulated environment, * Describe your role and one solution you translated from a business or user need into a working product or prototype. What problem were you solving?

• How did you approach the backend and frontend implementation? What were the key technical decisions you made?

• What was the hardest technical and/or organizational challenge you faced in relation to the above question, and how did you address it?

• What was the impact of your work (measurable outcomes, validated hypotheses, or lessons learned)? What would you do differently next time?
