Job description

Are you interested in building the engines behind the game? Do you thrive at the intersection of complex data architecture and sleek, high-performance user interfaces? If you are a master of Python and modern JavaScript who loves creating massive Content Management Systems and Business Intelligence dashboards that empower designers to craft experiences, we want to hear from you. Join our international studio in bridging the gap between raw data and creative vision in a remote role that challenges your full-stack capabilities every single day.



Responsibilities:


  • Next-Gen Tooling: Design, build, and maintain internal tools, configuration systems, and CMS platforms that allow game designers to balance gameplay and manage assets in real-time.

  • High-Performance Frontend: Develop lightning-fast, responsive user interfaces using React, Vite, and Tailwind CSS, ensuring a seamless experience even when handling thousands of configuration records.

  • Data-Driven Decisions: Help shape and implement complex systems with dashboards that visualise player metrics and game economy data, turning raw numbers and various sources of data into actionable insights.

  • Backend Scalability: Engineer optimized backend solutions with mainly Django, sometimes also flask, fast-api focusing on efficient database queries and API performance to support heavy data loads.

  • System Creation: Help create and design interfaces according to modern standards (Vite/Tailwind) and ensure the reliability of content delivery pipelines.

  • AI-Driven Prototyping: Use the power of Artificial Intelligence to rapidly prototype complex UI/UX concepts and accelerate coding workflows, using AI assistants to validate ideas faster and push technical boundaries.

  • Building the project from greenfield: Ability to work on new project builds from the ground up.

  • App Monitoring: Leveraging for real-time bottleneck identification and performance optimisation.




Requirements:


  • Experience: Around 7+ years as a Full Stack Developer with a proven track record in the GameDev or Data-Tech industry.

  • Front-end Proficiency: Demonstrated ability to create and configure modern frontend applications from scratch. Expertise in setting up and customizing UI libraries (specifically Tailwind CSS) and managing robust client-server communication and data fetching from various sources.

  • Stack Mastery: Deep expertise in Python (Django/DRF) coupled with modern frontend proficiency in React and TypeScript.

  • Modern Build Tools: Hands-on experience with Vite architecture and tooling; ability to optimize build times and application performance.

  • Complex Systems: Proven experience working with large-scale Content Management Systems (CMS), Asset Management tools, or data-heavy BI platforms.

  • Database Proficiency: Strong command of SQL (PostgreSQL preferred) and experience optimizing queries for large datasets.

  • Monitoring & Observability: Proven ability to maintain system health and rapidly diagnose production issues using Kibana (logs), Sentry (error tracking), and Datadog (metrics/APM). Experience in configuring proactive alerting workflows and Slack integrations to minimize downtime.

  • Testing Culture: Strong commitment to code quality and reliability, with experience writing unit tests for both backend (e.g., Pytest) and frontend (e.g., Vitest, React Testing Library).

  • Collaboration & Methodology: Active participation in Agile/Scrum rituals (daily standups, sprint planning) and a strict adherence to Code Review standards to ensure quality. Exceptional cross-functional communication skills are essential to thrive in a predominantly remote environment, as you will be building central systems that impact the daily workflows of every team in the company (from Design and Art to QA and DevOps).

 

Nice to Have:

  • Game Engine Knowledge: Familiarity with Unreal Engine or Unity data structures and blueprints is a massive plus.

  • Javascript Libraries: Experience with libraries like D3.js, Next.js, Recharts, Chart.js, react-flow, jsonforms, react-hook-form, codegen, apollo, react-query,

  • UI/UX Standards: Experience in building and maintaining scalable Design Systems.
