Jobs Frontend

We’re looking for a frontend engineer who genuinely cares about how things look, feel, and work — across every screen and device. If you’re the kind of person who notices misaligned pixels, checks responsiveness on five different browsers “just in case,” and enjoys deep focus on a single task until it’s right, you’ll feel at home here.

What you’ll do

• Build and maintain high‑performance gaming & betting interfaces using Svelte, SvelteKit, and TypeScript
• Work closely with designers (Figma) to deliver pixel‑perfect, responsive layouts
• Ensure consistent behavior across various devices, browsers, and screen sizes — from desktop to mobile
• Use WebSockets for live odds, real‑time updates, and in‑game events
• Follow Feature‑Sliced Architecture for clean, scalable code
• Write modern CSS (SCSS or Tailwind CSS)

What we’re looking for 

• Curiosity — you like understanding how things work under the hood, not just copying solutions 
• Deep focus — you can concentrate on one complex task for hours without context‑switching
• High standards — you notice when a layout breaks on a tablet or a shadow is off by 1px
• Cross‑device awareness — you know that “responsive” means more than just mobile and desktop
• Strong experience with Svelte/SvelteKit and TypeScript
• Solid CSS skills with modern frameworks (SCSS or Tailwind)

We Offer

• Competitive compensation package (depends on your experience and skills).
• Fully remote work with flexible hours (within the CET/EET time zone) from any location of your choice.
• 29 business days of vacation and paid sick leave.
• Corporate equipment (laptops, monitors, etc.).
• Professional courses/certifications (200 EUR per year).
• Operating in a start-up environment with cutting-edge technologies and unlimited investments in software upgrades, free from legacy systems or outdated solutions.
• Values-driven culture with a friendly and supportive work environment.
• Matrix organizational structure designed to streamline communication, remove barriers, and promote efficiency.

We’re not looking for someone to just “join the team” - we’re looking for someone ready to shape the product, lead meaningful growth, and make an impact from day one.

If that sounds like you, send over your CV and let’s talk!

About the client

Our client is looking for a hands-on Principal Integration Engineer & Architect to lead the design, evolution, and execution of our core data integration ecosystem.

• Advanced Integration Expertise: Extensively experienced interfacing with chaotic external REST/GraphQL APIs, webhooks, asynchronous event queues, and state management systems under high volumes.
• Data Modeling & Schema Excellence: Expert-level understanding of relational (SQL) and non-relational (NoSQL) databases, schema design, complex data validation, mapping workflows, and ETL pipeline design.

• True Builder Mentality: A strong architectural thinker who actively rejects the "ivory-tower" approach and remains deeply passionate about shipping high-quality production code every single week.
