Deliver Quality at Speed: Build clean, tested, and maintainable code with performance, scalability, and UX in mind
Contribute to Team Excellence: Take part in thoughtful code reviews, documentation, and monitoring (Sentry, Datadog)
Learn & Iterate: Participate in A/B tests, analyze outcomes, and use insights to guide product and code decisions
Own What You Build: From development to deployment, be accountable for delivering features that perform reliably in production
Required skills:
Experience in frontend development (3+ years) at a product-driven company
Proficiency in JavaScript (ES6+), TypeScript, React, and Redux Saga
Strong understanding of REST APIs, Core Web Vitals, and responsive design
Solid grasp of software design principles (SOLID, design patterns, maintainable architecture)
Experience working in cross-functional, fast-paced agile teams and communicating effectively in English (C1)
A curious, user-first mindset with a desire to deliver intuitive, delightful digital experiences
Nice to have:
Experience working with experimentation platforms and running A/B or multivariate tests
Experience with Material UI and its design philosophy
Familiarity with Next.js, SSR, and performance optimization
The confidence to set up or optimize bundler configs (Webpack/Vite) from scratch
Candidate journey: â•ď¸Ź Recruiter call ----> â•ď¸Ź Live Code Design Review ---> â•ď¸ŹSystem Design Interview -----> â•ď¸Ź Meet the hiring manager
✨ Why You’ll Love Being Part of Welltech:
Grow Together: Join a culture that champions both personal and professional growth. Here, you’ll thrive as we learn, evolve, and succeed together.
