Role Overview 
We are seeking a talented and driven Senior Engineer to join our development team. In this role, you will design, build, and improve backend solutions that power our critical business systems. 
As part of a growing and evolving team, you will work in a fast-paced, collaborative environment where you can influence how we build software, helping us continuously raise the bar on our practices, architecture, and code quality while delivering reliable, high-throughput systems that process millions of financial transactions.
 

What You Will Do  

• Champion a culture of AI-first development within the team, evaluating new tools and techniques that help us work smarter, not harder.  

• Actively explore and integrate AI tools and workflows into the development lifecycle, including code generation, automated testing, and intelligent code reviews, with the goal of eliminating repetitive tasks and maximizing engineering productivity.  

• Design, develop, and evolve backend applications with a focus on clean architecture and object-oriented principles. Our current stack is Java based, but we value engineering fundamentals over language specific experience.  

• Promote and deliver clean, efficient, and well documented code, including unit and integration tests, pushing the team towards better engineering standards.  

• Collaborate with cross-functional teams to define, design, and deliver new features and improvements.  

• Identify and address technical challenges, continuously improving system performance and reliability.
   

Who You Are  

• Genuinely interested in evolving towards an AI-first software development lifecycle through the use of AI coding tools (e.g., GitHub Copilot, Cursor). You see AI as an opportunity to offload work and focus on higher-leverage tasks.  

• Strong understanding of object-oriented programming (OOP) principles, design patterns, and SOLID principles, with 5+ years of experience in software development. Experience in Java is a plus, but solid OOP skills in any modern language (C#, Kotlin, etc.) are equally valued.  

• Experienced in owning tasks end to end, ensuring quality and delivering value in Agile/Scrum environments.  

• A self motivated and detail oriented professional who thrives in a collaborative team setting.  

• Skilled at breaking down complex problems and creating clear, actionable plans to address them.  

• Proficient in communicating technical concepts effectively to both technical and non-technical stakeholders.  

• Passionate about continuous learning and mentoring team members.  

• Familiarity with frameworks such as Spring and testing tools like JUnit is a plus.  

• Solid understanding of SQL databases (e.g., MySQL) and experience in Linux/UNIX environments.  

• Knowledge of CI/CD pipelines and container technologies such as Docker and Kubernetes is a plus.  

• Interested in DevOps as a mindset, not a role. You care about the full lifecycle of the software you build, from development through deployment, monitoring, and continuous improvement.
