About Hacksaw Studios

Hacksaw Studios creates online games that run in both social and real-money modes, played by millions of people worldwide each month. To support our expanding technical landscape, we’re looking for a Client Platform Developer to join our Stockholm team.

This position focuses on primarily client-side work—building and maintaining a range of web-based products and tools, from in-game UI and back-office systems to our round-replay system and integration frameworks. However, you may occasionally work on back-end tasks as well. You’ll be part of a small but growing team that spans multiple domains, ensuring our platform remains robust, scalable, and user-friendly for both internal teams and third-party partners.

What You’ll Be Doing

Develop and Maintain: Work on core web-based products such as our in-game UI and back-office systems.
Integration & Collaboration: Manage client-side integrations of our games with various external platforms and support third-party studios building on our OpenRGS platform. Collaborate with back-end teams to align integration strategies with our broader platform architecture.
Tooling & Automation: Create and maintain help-tools (e.g., scripts for changelog generation, mock clients, game launchers) to optimize workflows across different departments.
Technical Support: Provide expertise and troubleshooting for platform-related issues, working closely with developers, QA, and customer support teams.
UX & Visual Detail: Contribute to user-friendly interfaces and ensure a polished look and feel for our products.

What We’re Looking For

Proficiency in JavaScript/TypeScript or a similar language. (Experience with Haxe, our main client-side language, is a plus but not mandatory.)
Strong Understanding of Web Technologies: Familiarity with browser APIs, cross-origin communication (e.g., postMessage, CORS, WebSockets), and third-party service integrations.
Debugging & Problem-Solving Skills: Experience using browser DevTools, Postman (or similar tools), and a structured approach to identifying and resolving issues.
Communication Skills: Ability to articulate technical concepts clearly to both technical and non-technical stakeholders.
Service-Minded & Proactive: Comfortable owning problems, driving solutions, and collaborating with diverse teams.
