We are looking for a skilled React / Javascript developer to join our front-end development team. In this role, you will be responsible for developing and implementing user interface components using React.js concepts and workflows such as Redux, Flux, and Webpack.
**Who are we and what do we do:**
Holofy is at its core a technology that specializes in digitizing the real world so it can be transacted at the speed of light. In order to achieve that, we've built an entire sales engagement platform on top of video, as we believe it's the most powerful tool to story-tell beating any other medium ( such as 3D ) hands over fists. Whilst this is the most visible and simplest to understand value proposition, our moat comes from the complex set of algorithms, data structures and workflow tools that make our entire experience work at scale.
We operate as a SAAS, but our services can be described as B-to-B-to-C covering the entire spectrum of a user's conversion journey. We offer our product to Real-Estate businesses, as they have yet to unlock the fundamental power of software and user experience working together in unison.
Being part of Holofy means pushing yourself to do the best work in your life. Our existence and success as a startup literally depend on excellence as the only competitive advantage against competitors that are bigger than us, richer than us, and more visible than us. It's a scary and exhilarating place to be in. If that sounds like you, here are the details
**What you will do:**
* Create extremely well-crafted front-end web applications using React.js (with Hooks), Redux
* Build reusable cross-platform components and front-end libraries for future use
* Write resilient code that will be continuously tested, deployed, and performed at scale
* Be part of a self-organizing and cross-functional Agile team
* Support in leading within the team, actively improving overall software quality whilst also helping fellow team members
* Contribute to the team's technical direction and the improvement of its tools and processes as well as technical interviews

* At least 2 years experience working with React.js
* Good understanding of Browser Rendering Behavior

* Experience with any state management approach
* Unit, Integration, e2e tests

* Performance optimization
* GraphQL
* Some experience with build tools and task runners
* React Native
* Experience with cloud (AWS)
* Experience with building in Web widgets or Extensions
* Familiar with react-spring or any animation libraries
**The perks:**
* Fully flexible, work-from-anywhere policy. Forever. With reasonably flexible hours included. As long as you are reachable you can literally be on a beach or in the mountains for all we care.
* Solid equipment budget ( Macbook's + full work-from-home setup ), that most probably will stay with you when you move on.
* Medical Insurance. One that is not just for show, it actually keeps you and your family safe.
* 30-day paid holiday
* Educational Stipend
* EPAM Employee Stock Purchase Plan (ESPP) (subject to certain eligibility requirements)
