About StoneX Enterprise Technology and global payments

StoneX Global Payments is a leading global payments fintech providing cross border FX and payments solutions to corporations, NGOs, and institutions across 180+ countries and 140+ currencies. Our mission is to build the next generation global payments platform scalable, efficient, fault tolerant, and powered increasingly by intelligent automation.

We are undergoing a multi year modernization effort across our front, middle, and back office systems, leveraging cloud-native architectures, microservices, and now agentic AI engineering to accelerate delivery and reshape end to end payment flows.

Responsibilities

Role Summary

We are seeking a Principal Engineer with deep agentic development experience to lead major components of our Payments technology transformation. You will architect, design, and implement mission critical distributed systems while driving adoption of agent powered engineering using tools such as Claude Code and emerging autonomous development agents.

This role sets technical direction, accelerates delivery using AI augmented workflows, and enables engineering teams to achieve 10-20 productivity improvements through structured, agent ready codebases.

Key Responsibilities

1. Architecture Technical Leadership

- Lead the design and development of distributed, microservice based enterprise applications using Java, Spring Boot, and cloud native patterns.
- Shape the future Payments platform architecture and contribute to front to back re engineering initiatives across GP.
- Drive system design excellence through formal design reviews, ADRs, and technical deep dives.
- Ensure high standards for reliability, performance, scalability, and observability.

2. Agentic Development Leadership

This is the major differentiator of the role.

- Introduce, design, and operationalize agent based engineering workflows across the SDLC.
- Use tools such as Claude Code,



capable of repository wide reasoning, automated refactoring, debugging, and commit generation to accelerate engineering throughput.
- Build agent ready codebases through modular design, clean documentation, and comprehensive test coverage key enablers of successful agentic development.
- Actively contribute to and/or lead the recent agentic development team for Payments (e.g., new wallet solution POC).
- Evaluate AI generated code for quality, correctness, architectural alignment, and security.
- Develop internal best practices, training materials, and standards for agent accelerated engineering.

3. Delivery Execution

- Deliver high quality software aligned to business needs and customer outcomes.
- Translate product requirements into scalable technical solutions; break down complex features into actionable tasks.
- Implement robust automated testing and continuous integration practices.
- Diagnose, debug, and resolve complex issues across distributed systems and environments.
