Lead Java/Fullstack Developer (Backoffice)

Who We Are

At Patrianna LTD, we’re building a global social entertainment platform, focusing on innovative sports-oriented skill games for the North American market. With a reach of up to 150 million players worldwide, we combine creativity and technical excellence to lead in the dynamic world of social gaming.

Who We’re Looking For

We are seeking an exceptional Lead Java/Fullstack Developer with a profound, product-first mindset. This isn't just a coding role, it's a leadership position where you will be the primary advocate for user experience and workflow excellence within our backoffice system.

We are looking for someone who:

Drives Vision and Strategy: You don't wait for specs. You proactively analyze internal operations (across compliance, risk, support) to identify systemic friction and inefficiencies. You will set the technical and UX direction for our backoffice solution, ensuring it evolves into a truly intuitive, efficient, and scalable platform for non-technical users.

Champions the Internal User: You are deeply passionate (perhaps even obsessive) about workflow clarity and interface logic. You treat our internal (admin) users with the same care and respect a product designer shows external customers. You are compelled to build tools that people genuinely want to use.

Mentors and Elevates: As a Lead, you’re ready to guide, mentor, and set a high bar for technical quality and UX design for others working on the backoffice system. You take pride in simplifying complexity and enabling your teammates to deliver their best work.

If you thrive on full ownership, are energized by the challenge of solving complex business problems through elegant UX, and are ready to be the driving force behind a mission-critical platform, we want to talk to you. Come and help us define what a world-class backoffice system looks like.

Responsibilities

• Lead Technical and Product Direction: Define the technical architecture and contribute to the product roadmap for the backoffice system, ensuring it meets the strategic needs of internal operations (Compliance, Risk, Support).

• Drive UX/Workflow Excellence: Deeply analyze internal user workflows to proactively identify and eliminate systemic friction, ensuring the backoffice platform is intuitive, efficient, and genuinely enjoyable for non-technical users.

• Mentor and Elevate the Team: Serve as a technical guide and mentor, setting a high bar for engineering quality, clean code, comprehensive testing, and thoughtful UX design across the backoffice development team.

• Full-Stack Feature Development: Design, develop, and evolve robust full-stack features, connecting frontend logic in Retool with scalable, high-performance backend APIs and data layers (Java/Spring Boot).

• Stakeholder Collaboration: Work closely with non-technical stakeholders to gather feedback, translate complex business requirements, and deliver impactful, practical technical solutions.

• System Ownership & Reliability: Take end-to-end ownership of the system's reliability, security, and usability, championing best practices and managing technical debt.

• Proactive Challenge: Challenge unclear or inefficient requirements and actively suggest smarter, more elegant, and scalable approaches to solving core business problems.
