• Lead and mentor the dev team, with strong code review culture
• Build and integrate robust front-end (React/Angular) and back-end (Node.js, APIs) layers
• Collaborate with product and cross-functional teams on real-time, data-intensive features
• Push the bar on performance, scalability and code quality

What we're looking for

• Solid command of HTML, CSS, JavaScript and React or Angular
• Strong back-end skills in Node.js, API design and server architect...
