Backend Tech Lead

About LokalIn 2018, we began with a WhatsApp group with a simple hypothesis: people in tier-2/3 towns weren't really using the internet meaningfully yet. We believed that if we started with local content in their own language, they'd come back every day; once there was a habit and trust, that same space could naturally grow into classifieds and, eventually, something they used for almost everything online.This spark became Lokal. Our first instinct was to put everything in one place & one app - local updates, classifieds, jobs, matrimony and more. It worked, till it stopped working. Users gave us the insight - when one use case outweighs the others, everything else seems like noise. We listened. Like how Craigslist quietly seeded a generation of focused companies & marketplaces, we began unbundling and verticalising.Today, Lokal is a house of focused apps, many products, one mission:To connect Tier-2/3+ India to the Knowledge, opportunities, tools and experts they've always deserved.We now operate dozens of live apps across categories like:Edutainment & Skill Learning – practical skills and learning in regional languages (GyanTV)Matrimonial Matchmaking – hyperlocal, compatibility-first partner search (Lokal Matrimony)Agri Consulting – farmer-first advisory in local languages (AgriLokal)Local Jobs – blue- and grey-collar opportunities close to home (Lokal Jobs, Sahi Jobs)Social & Community – Place to find & post social updates (Lokal app)Emotional Well-being & Peer Support – safe spaces to talk and feel heard (Dostt & Eaze)Astrology & Guidance – instant access to trusted Astrologers via chat and voice (AstroLokal)Advisory Services – early bets in legal help, financial guidance, career counselling, and moreUnder the hood, Lokal is a discovery and access platform: local-language internet + deep Bharat insight+ AI.
