Skills, Knowledge and Expertise 🚀

Hard skills ⚡

Frontend frameworks (React, Vue, or Angular) 🖥️ – You’ll be building user-facing features, so knowing your way around a modern frontend framework is essential to create sleek, snappy, and delightful experiences.
Backend technology (Express, Python, or PHP) 🔧 – While JavaScript is our main playground, we’re interested in your other backend experience too! The key is knowing how to build solid, scalable server-side logic.
Extensive experience working with JS/TS 💻 – JavaScript and TypeScript are at the heart of everything we do. We need someone who knows them inside out, best practices, quirks, and all.
NoSQL databases like MongoDB 🗄️ – You should be comfortable working with document-based databases, structuring data efficiently, and making sure our apps run smoothly.
Worked with CI/CD pipelines 🚀 – Shipping fast and often is the goal! Experience with CI/CD means you know how to automate testing and deployments, keeping things moving with minimal hiccups.
Testing tools (Jest, Cypress, Mocha) 🧪 – Bugs are fun… said no one ever. You should be experienced with modern testing tools to ensure reliability and catch issues before they reach our users.

Soft skills ✨

Hyper collaborative 🤝 – We’re all about teamwork! You’ll be working closely with engineers, designers, and product folks, so we need someone who thrives in a highly collaborative environment.
Product-minded 🚀 – You don’t just write code for the sake of it, you think about the customer impact. We love engineers who are curious about how features improve the user experience and drive business goals.
Strong communicator 🗣️ – Whether it’s explaining a technical decision, giving feedback, or breaking down complex ideas for non-tech teammates, clear and thoughtful communication is a must.
Kind ❤️ – No room for egos here. We value kindness, respect, and a supportive attitude. We want someone who lifts others up and contributes to a positive team culture.
