Job description

Our client is one of the largest game studios known for its very successful online MOBA and FPS franchises. You will be part of a Player Platform team responsible for building and maintaining a web portal for players and internal teams at the company.


The Player Platform Portal is a gateway to multiple internal backend systems and plays a crucial role in the development cycle of all the games at the company.


You will work closely with the engineering team in Los Angeles and other locations in the US West Coast.

Due to working across multiple time zones, flexibility to attend later meetings on a DAILY BASIS is an important factor for success in this role (up to 9-10PM CEST).

 

Each team member is expected to proactively propose tools, designs, and implementation strategies.


Responsibilities:

  • Partner closely with Senior Engineers and Design to create and iterate on well crafted user experiences

  • Build out complex web applications that support the Player Platform Portal development

  • Work with partner teams and platforms to bring experience to life

  • Quickly iterate on prototypes and new areas to find feasible solutions for the products we are building

  • Create, manage and document RESTful APIs

  • Write and execute unit, integration and end-to-end tests, participate in code reviews


Required qualifications: 

  • 5+ years of experience with Frontend Technologies

  • 4+ years of experience with React

  • Bachelor's or higher degree in Computer Science, Software Engineering, or a related field

  • Strong frontend focus with the skills to dive into backend when needed - comfortable across the stack, but passionate about crafting great user-facing experiences

  • Deep hands-on programming experience with Typescript, React and CSS-in-JS paradigms

  • Real-Life Experience using modern Web Frameworks, such as NextJS, Astro or SvelteKit

  • Good understanding of modern web architecture and technologies

  • Working with PaaS Vendors like Netlify

  • Attention to detail, including spacing, CSS animations, and user experience nuances

  • Understanding of accessibility standards and guidelines (e.g., WCAG)

  • Experience with version control tools (e.g., Git) and build tools (e.g., Webpack, Vite)

  • Aptitude for debugging, analyzing issues, and implementing effective solutions

  • Effective communication and teamwork skills


Nice to have: 

  • Experience working with advanced GQL topics, such as Subscriptions and Federation

  • Familiarity with testing frameworks (e.g., Jest, RTL, Playwright)

  • Hands-on experience working with Public Cloud, preferably AWS (Lambda/Serverless)

  • Experience with observability and monitoring tools, preferably Datadog
