About the Role
We're looking for a Senior Fullstack Engineer with a strong frontend focus to join a high‐impact international FinTech project building an internal Customer Experience Operations Platform.
The platform provides the tools customer experience agents and supervisors rely on every day to manage queues, assignments, conversations, agent availability, dashboards, metrics, and operational workflows.
You'll primarily design and ship agent‐facing experiences using React and TypeScript, working within a modern, modular frontend architecture while collaborating closely with the backend services and APIs that power the platform.
A key aspect of this opportunity is the way the team approaches software development.
We're looking for engineers with an agentic development mindset: people who actively use AI coding assistants, LLM agents, automation, and AI‐assisted engineering workflows to prototype faster, solve problems, generate and validate code, improve testing, accelerate debugging, and increase overall engineering productivity.
This is not simply about using AI autocomplete.
We're looking for engineers who are comfortable incorporating tools such as Cursor, Claude Code, GitHub Copilot, coding agents, custom scripts,



or AI‐assisted specifications into their day‐to‐day development process while maintaining strong engineering judgment and ownership.
You'll work closely with Product, CX stakeholders, designers, and backend engineers to turn operational requirements into reliable, intuitive, and where.
