Senior Software Engineer - Fullstack-Payments

We are seeking a Senior Software Engineer with deep experience in designing and building scalable,

high-performance systems using Java, Spring Boot, Angular/React, and cloud-native

architectures. This role will play a key part in driving the technical direction for our key Retail

architecture, streamline distributed workflows, and lead the development of robust, enterprise-grade

solutions.

This role will work closely with engineering, product, and business teams to deliver highly responsive,

secure, and maintainable applications. We are seeking someone who can operate both strategically

and hands-on — someone who enjoys rolling up their sleeves to solve hard problems, while also

influencing long-term platform decisions.

• Define and enforce architecture standards, coding practices, and technical guidelines across

the team.

• Collaborate with Product Managers, Revenue Management, and operations teams to ensure

alignment of technical solutions with business needs.

• Oversee code quality through reviews, automated testing, performance tuning, and CI/CD

practices.

• Mentor and guide software engineers, fostering a culture of innovation, collaboration, and

continuous improvement.

• Actively participate in system design reviews, architecture discussions, and capacity planning

for the platform’s evolution.

• Drive the modernization of legacy systems into cloud-native, API-first architectures in Azure.

• Stay current with emerging technologies and drive the adoption of tools and practices that

enhance productivity and system performance.

• Coordinate with US-based engineering leadership on priorities, sprint planning, and cross-team

dependencies.

• Drive adoption of AI-assisted development tools (GitHub Copilot, AI code assistants, AI-driven

testing) across the team to accelerate velocity, improve code quality, and embed an AI-native

SDLC mindset as standard engineering practice.
