R&D Team Leader

Join us at Nayax, a global fintech leader (NASDAQ; TASE: NYAX) revolutionizing the world of cashless payments, consumer engagement, and business management solutions. With more than 1,200 employees across 12 offices worldwide. At Nayax, you'll be part of a diverse and innovative community where your work makes a real impact and helps shape the future of payments.

Retail Pro International (RPI) is a global leader in retail management software, empowering retailers in over 80 countries with flexible, scalable, and powerful solutions. Our mission is to enable retailers to thrive in a rapidly evolving landscape by delivering innovative technology, deep industry expertise, and a commitment to long-term partnerships. RPI was acquired by Nayax in 2023 and has been merged into the company's product portfolio.

We are currently looking for a R&D Team Leader to join our team and play a pivotal role in shaping the future of our company.

In this role, you will lead the modernization of one of the retail industry's most battle-tested POS platforms. Retail Pro is a mature enterprise retail ecosystem with over 20 years of domain knowledge, powering complex retail operations, POS flows, payments, replication, and back-office systems across global markets.

This role is not about maintaining legacy software - it is about transforming a proven platform into a modern, AI-augmented engineering organization and technology stack. This is a hands-on leadership role for someone energized by complexity, large-scale modernization, and building high-performance engineering culture. The ideal candidate combines architectural depth, strong execution capability, AI-first thinking, and the ability to lead teams through deep technical and organizational change while continuing to deliver production value to customers.

The environment includes legacy Delphi/Pascal backend systems, Angular-based frontend platforms, replication-heavy infrastructure, cloud migration initiatives, and emerging AI-assisted engineering workflows.

The R&D Team Leader will report directly to the CTO, Retail Pro & Retail.

Role Summary:

As the R&D Team Leader, you will own the technical and organizational evolution of the Retail Pro platform. You will lead a mixed-seniority engineering organization through a multi-year modernization journey spanning backend architecture, frontend modernization, cloud infrastructure, AI-assisted development, engineering processes, and operational scalability.

You will act as both a strategic technical leader and a player-coach: defining architecture, reviewing code, mentoring developers, introducing AI-driven workflows, and building a modern engineering culture from the ground up. You will work closely with executive leadership, product management, and engineering teams to balance long-term modernization with ongoing customer delivery commitments.

This role is ideal for someone who sees large legacy systems not as a burden, but as an opportunity to create massive leverage through modernization, AI adoption, and engineering excellence.

Your key responsibilities will include:

• Lead the modernization of a mature enterprise retail platform from legacy technologies toward a scalable, cloud-ready architecture
• Define and execute a phased migration strategy for Delphi/Pascal backend services toward modern backend technologies and service-oriented architecture
• Drive adoption of AI-assisted engineering practices across development, QA, documentation, code review, onboarding, and operational workflows
• Introduce and standardize engineering processes including specifications, architecture reviews, sprint planning, CI/CD, code review, testing standards, and release management
• Lead frontend modernization initiatives across Angular applications and NX monorepo architecture
• Redesign replication-heavy and tightly coupled infrastructure into scalable, observable, resilient distributed systems
• Evaluate and guide database modernization initiatives including Oracle/MySQL migration strategy toward PostgreSQL and cloud-native architectures
• Build engineering culture focused on ownership, velocity, quality, accountability, and continuous improvement
• Mentor developers across multiple seniority levels while identifying capability gaps and making difficult staffing decisions when necessary
• Reduce dependency on tribal knowledge by driving documentation, architecture mapping, and AI-assisted knowledge extraction
• Lead QA modernization initiatives including automated testing strategy, AI-assisted QA tooling, and release confidence improvements
• Improve observability, monitoring, operational tooling, and production diagnostics across the platform
• Partner with executive leadership to translate technical debt, architectural risk, and modernization priorities into actionable business decisions
• Define practical AI integration opportunities inside the product itself, including AI-BI capabilities, data connectivity, and future AI-driven retail workflows
• Balance long-term architectural improvements with short-term customer and business delivery needs

What Makes You a Great Fit

• 7+ years of software engineering experience with at least 3+ years leading engineering teams or technical organizations
• Proven experience leading modernization of large legacy platforms into modern architectures in production environments
• Strong hands-on engineering background with experience reviewing architecture, debugging complex systems, and guiding implementation details
• Experience working with large, mature codebases containing significant technical debt and historical business logic
• Deep understanding of modern engineering practices including CI/CD, code review, testing strategies, observability, and cloud-native development
• Strong experience with distributed systems, transactional systems, or high-availability enterprise platforms
• Experience driving cloud migration initiatives and modern infrastructure adoption (AWS preferred)
• Demonstrated use of AI-assisted development tools such as Claude Code, GitHub Copilot, Cursor, or similar tools in real engineering workflows
• Strong understanding of where AI tooling accelerates engineering and where governance, review, and guardrails are required
• Experience mentoring engineers, building teams, improving engineering culture, and raising organizational technical standards
• Strong communication skills with ability to explain technical trade-offs and modernization strategy to non-technical stakeholders
• Comfortable operating in environments with incomplete documentation, evolving processes, and organizational ambiguity
• Strong prioritization skills and ability to balance modernization efforts against active product delivery commitments

Nice-to-Have Skills

• Experience with Delphi/Object Pascal or other legacy enterprise technologies
• Experience with C# / .NET - particularly in enterprise backend modernization, Windows-native services, or migration paths from legacy COM/Delphi environments
• Experience modernizing enterprise POS, retail, fintech, payments, or transactional platforms
• Experience with NX monorepos, Angular modernization, or frontend platform migration initiatives
• Experience designing AI-assisted internal developer platforms or AI-enabled product capabilities
• Experience with PostgreSQL migrations and database modernization strategy
• Familiarity with event-driven architectures, RabbitMQ, replication systems, or offline-first enterprise systems
• Experience building automated QA frameworks in legacy environments
• Experience integrating AI systems with internal business data, analytics, or BI infrastructure
• Strong DevOps or platform engineering background
• Experience leading hybrid teams of internal engineers and external contractors

Compensation and Benefits

• The base salary range for this position is $150,000-$180,000 per year
• Eligibility for an annual performance bonus and additional benefits.
• Final compensation will be determined based on experience and qualifications.
