Senior Frontend Developer

Join us in building the ultimate online playground! Poki is on a mission to create the ultimate online playground, bringing easy access to the best games on web to over 100 million monthly players worldwide. These games are created by a dynamic global community of 500+ game developer teams. At the core of our work lies a simple belief: play is how we learn. This value is embodied by our team of 70 unique individuals who each bring something special to the table. What this job is about As a senior Frontend Developer at Poki, you’ll shape how players experience our platform. You will work on high-impact features and improvements, enhancing content discovery, social interactions, and performance. Whether you’re working on improving gameplay experience, running an A/B experiment, or making a new tool for our Content team, your work will directly impact our players. This is a senior role. That means we expect judgement, not just throughput. Your challenge as a Senior Frontend Engineer Building and Optimizing at Scale : You'll help ensure a smooth, lag-free experience for millions of players across various devices and network conditions. Contributing to Code Quality : We value clean, maintainable code. Poki is built on top of React + Redux, and you’ll help ensure the long-term quality of our codebase through peer reviews, sustainable practices, and constant improvements. Collaborating on Features : Work with cross-functional teams to design and implement features that improve the gameplay experience, community interaction, and player engagement. Ensuring a Seamless Multi-Device Experience : Poki is accessed across desktops, tablets, and mobiles. Your role is to make sure everything works smoothly and consistently, regardless of device or screen size. Experimenting and Iterating : As part of a fast-moving team, you’ll experiment with new features, launch A/B tests, and constantly refine the platform to improve user experience and performance. You Have deep frontend craft and the scars to prove it. We care about the scope and complexity of the work you've owned, not how many years you've been doing it. Are fluent in React and Redux, and you know how to build SPAs that are still maintainable after year two. Have advanced skills in HTML/CSS/JavaScript/TypeScript, creating responsive, performant layouts that work seamlessly across different devices and browsers. Write tests, but you don't test things for the sake of watching a number go up. You know which tests are worth writing and you’ve worked with Playwright or something similar. Understand that AI has changed how work gets done and you've already adapted your way of working around it. You use it to move faster without handing over your judgement or responsibility for the result. Are familiar with Figma or a similar tool, and are comfortable translating designs into interactive web components.
