About TectSoft

TectSoft is a Lahore-based software company building production-grade mobile and web

applications for North American clients. We’ve delivered 50+ live apps across health, fitness,

productivity, and lifestyle industries. Our engineering stack is centered around React Native,

Supabase, PostgreSQL, and Next.js, and our developers work directly with founders, startups,

and product teams across the US & Canada. We’re hiring a Senior React Native Engineer

(Tech Lead) to lead delivery across our mobile portfolio while owning frontend architecture,

backend systems, and database design end-to-end.

The Role

This is a senior full-stack mobile engineering role with a strong focus on React Native

frontend architecture. You’ll lead development across production mobile apps while also

owning backend systems and database architecture using Supabase and PostgreSQL. From

project kickoff to App Store release, you’ll be responsible for building scalable, maintainable,

production-ready applications. You’ll work directly with clients, lead technical decision-

making, mentor developers, review code, and establish engineering standards across projects.

This is not a task-execution role — we’re looking for someone who can think like a technical

owner.
