Jobs Developers

Who We Are

At Patrianna LTD, we’re building a global social entertainment platform, focusing on social gaming 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.

About the Project: We are building a massive, proprietary Ticketing & Event Management Ecosystem for the US market. This is NOT a standard booking site. We are engineering a custom, high-load platform from scratch. The ecosystem includes:

• Complex Web Platform: Handling Reserved Seating schemes, Camping bookings, and deep Event Management logic.
• On-Site Operations: Gate Scanning functionality and Ticket Printer control. We develop the scanning logic and integrate it with physical hardware for printing.

• Mobile Ecosystem: A feature-rich mobile application for organizers and attendees.

   

We don't use "out-of-the-box" solutions. We build our own logic to handle heavy complexity. If you prefer solving technical puzzles rather than integrating standard plugins, this is your place.

⚠️ THE CULTURE (Read this first): We are a US-based startup in an aggressive growth phase. We are looking for a Founding Engineer mindset.

• Intensity: We work with the US market. Late evening calls (European time) are standard to sync with the founders.
• Ownership: You don't just "close tickets." You own the feature from the database architecture to the UI. If the Gate System goes down on a Saturday night during a festival, you are the one helping to fix it.
• No "Code Monkeys": We discuss business goals. You need to understand why we are building a feature. If a requirement doesn't make sense technically, we expect you to push back and propose a better solution.

Tech Stack: React, Remix, Tailwind UI, Node.js, NestJS, TypeScript, PostgreSQL (TypeORM), GCP infrastructure.

Requirements:

• 4+ years of engineering experience, with deep expertise in the Node.js/React ecosystem.
• Modern Stack Mastery: You are proficient with NestJS on the backend and React/Remix + Tailwind UI on the frontend.
• Architectural Grit: Experience building custom complex systems (booking engines, CRM, logistics). You know how to design database schemas (PostgreSQL/TypeORM) that won't break under load.
• Integrations: Experience with payment processors (Stripe, etc.) and—crucially—an interest in working with hardware integrations (printers, scanners, IoT).
• US Startup Availability: You are comfortable working late hours and staying responsive during critical festival launches.
• Mobile Awareness: Knowledge of mobile development (React Native) is a plus.
• English: Upper-Intermediate or higher. You must be able to explain complex technical trade-offs to the founders.

Responsibilities:

• Engineer the Core: Design and develop the backend and frontend for the Ticketing Platform.
• Solve Hard Problems: Implement logic for Reserved Seating, interactive maps, and complex order flows.
• Hardware & Gate Logic: Write code that interacts with the physical world (scanning tickets, printing).
• Performance: Optimize the app to handle traffic spikes during ticket sales drops.
• Quality & DevOps: Write testable code, manage CI/CD pipelines, and deploy to GCP. You break it, you fix it.

We Offer:

• High Reward for High Performance: Competitive salary + Advanced Bonus System (We reward those who build the business with us).
• Real Engineering Challenge: No CMS wrappers. Pure custom development on an actual stack.
• Direct Impact: Your code runs the show at real festivals in the US.
• Medical Insurance in Ukraine and Multisport program in Poland.
• Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
• Paid vacation, sick leaves, and official holidays.
• Legal & Accounting services.
• The company provides all necessary equipment.
• English classes and Education reimbursement (50%).
