Job Description

GR8 Tech builds B2B iGaming platforms for operators who play to lead.

We deliver full-cycle, high-impact tech designed to scale — from seamless integrations and expert consulting to long-term operational support. Our platform powers millions of active players and drives real business growth. Call it what it is: the iGaming Platform for Champions.

With 1000+ GR8 people across locations and time zones, we don’t just ship technology — we help operators build success stories across brands, markets, and geos.

Our ambition drives us. Our people make it real.

If you’re a challenger in spirit and a champion in action — join us.

Why this role exists:

This role exists to architect and deliver scalable, high-performance web interfaces. You’ll help us drive user engagement and shape our core product direction by owning the frontend architecture, mentoring the engineering team, and championing UI/UX best practices from initial design all the way to deployment.

What you’ll drive:

Architecture & Strategy

• Architect scalable and maintainable front-end solutions using React, modern JavaScript, and TypeScript.
• Drive the adoption of efficient state management and modular build processes (e.g., Webpack, module federation).
• Design resilient, failure-tolerant systems that account for load, performance, and web security (CORS, CSP, OWASP).

Delivery & Execution

• Ship complex, high-quality code to production in a timely manner to meet crucial business expectations.
• Optimize web pages for maximum speed and scalability by deeply tuning the event loop and rendering steps (style, layout, paint, composite).
• Validate code reliability by building out comprehensive testing infrastructure (Jest, React Testing Library, unit/integration testing).

Team & Leadership

• Mentor junior developers and elevate team standards through thorough, constructive code reviews.
• Partner with Product Managers, Designers, and Delivery Managers to align technical execution with overarching business goals.
• Unblock the team by debugging deeply rooted technical issues and creating Proof of Concepts (POCs) for new technologies.

What makes you a GR8 fit:

Must-have

• 5+ years in a senior frontend engineering role with a strong track record of shipping complex, user-facing web applications.
• Deep JS/TS Mastery: Deep understanding of modern JavaScript (event loop, closures, async programming) and advanced TypeScript (generics, advanced types).
• React Expertise: Strong command of React core concepts, component lifecycle, rendering optimization, and modern state managers (Redux, Zustand, etc.).
• Web Fundamentals: Expert knowledge of the browser rendering pipeline, DOM manipulation, semantic HTML5, and CSS preprocessors (Sass/Less).
• Tooling & Testing: Proficiency in configuring build tools (Webpack) and writing comprehensive automated tests.
• Communication: The ability to clearly articulate complex architectural decisions and trade-offs to both technical and non-technical audiences.
• Upper-Intermediate+ English and fluent Ukrainian.

Nice-to-have

• Familiarity with microservice/event-driven architectures and client-server communication (REST APIs, WebSockets).
• Experience with Cloud/DevOps practices (Docker, CI/CD pipelines, basic AWS/GCP/Azure knowledge).
• Basic understanding of backend database concepts (SQL/NoSQL) and broader system analysis.

Why you’ll love working here:

Benefits Cafeteria — annual budget you allocate to:

Sports • Medical • Mental health • Home office • Languages.

Work-life & support

• 20+ vacation days, unlimited sick leave, emergency time off.
