Responsibilities

This is the right role for you if you thrive in a fast-paced, collaborative environment and enjoy owning both code and outcomes — across the full stack.

You’ll work in a cross-functional team where backend, frontend, mobile, and design come together to deliver high-impact, user-centric features. As a Tech Lead, you’ll drive technical direction for your team — from database design to UI — and take accountability for scalability, performance, and code quality.

Your day-to-day will include building and reviewing production features, leading architectural decisions, mentoring engineers, and collaborating with the PM and QA to deliver reliable, well-scoped releases. You’ll also participate in client discovery sessions to understand their needs and shape the right solutions.
