Agentic AI Full Stack Developer

About the Role We are looking for a hands-on Full Stack Developer to design, build, and support AI-powered applications from the ground up in a fast-paced enterprise scale data environment for a growing Investment Bank. You will own both the frontend and backend, work directly with modern AI agent frameworks, and help shape the architecture of a new platform and building a brand new data control plane. This is a builder’s role for someone who enjoys taking a product from a blank page to a production-grade, well-tested system. What You’ll Do * Design and build end-to-end features across the UI and backend API layers. * Architect and structure new applications from scratch — data models, API contracts, service boundaries, and frontend structure. * Build and integrate AI agent workflows using frameworks such as LangGraph, LangSmith, Strands SDK, and Agent Core. * Develop responsive, accessible user interfaces with React.js, TypeScript, and/or Angular, including styling and UX polish. * Design and implement backend APIs (REST and/or event-driven) that power the application and integrate with AI services. * Work with relational and other data stores — modelling data, writing efficient queries, and building reliable data access layers. * Build with security and access control in mind (authentication, authorisation, role-based access) appropriate to a regulated financial environment. * Write unit and regression test cases to ensure reliability and prevent regressions. * Support and maintain the platform in production — monitoring, debugging, and iterating on live systems. * Collaborate closely with data, platform, and business teams to deliver features in an Agile environment. Required Qualifications * Proven, hands-on experience building both UIs and backend APIs. * Strong frontend skills with React.js, TypeScript, and/or Angular. * Solid backend development experience in a modern language (e.g., Python, Java, or Node.js). * Experience with databases and SQL, including data modelling and query design. * Experience designing application architecture and structure from scratch. * Practical experience with Agentic AI frameworks: LangGraph, LangSmith, Strands SDK, and Agent Core. * Experience writing unit and regression tests. * Proficiency with Git and modern code review / CI-CD delivery practices. * Comfortable owning both styling/frontend and backend/API concerns. Nice to Have * Cloud engineering experience with AWS, Azure, or Google Cloud Platform. * Experience writing evals to measure and improve AI/agent performance. * Experience supporting production platforms and CI/CD pipelines. * Familiarity with containerization and infrastructure-as-code. * Exposure to data governance concepts (lineage, cataloging, access control). * Prior experience in financial services or another regulated industry. What We’re Looking For A self-driven full stack engineer who is equally comfortable designing an architecture, styling a UI, wiring up an AI agent, and writing the tests that keep it all stable — someone who wants to build and own real products end to end.
