Senior Software Engineer - Backend [08 / 11 / 2025]

This is a foundational engineering role. Not a role where you just optimize endpoints or manage tickets. You’ll be helping architect the backend of a global, privacy-first communication platform— built from the ground up, on principles we don’t compromise. It’s an opportunity to craft a product that users love—and one that holds its own against WhatsApp, Teams, or Signal, not just in UX, but in security, auditability, and data control. You’ll build systems that deliver consumer-grade performance and military-grade privacy. We’re not iterating on someone else’s blueprint. We’re carving a new one.

Who are we?

We are a young product company scaling fast and outgrowing the startup tag—with global scale in our crosshairs. We don’t do “okay.” We give everything we’ve got to build the best communication platform in the world. Our team includes engineers from IIT and other top institutions—people who care deeply about the craft, performance, and purpose. You’ll learn more in 6 months here than most engineers do in 3 years elsewhere. We’re intense. High-strung. Focused. Our team includes engineers from IIT and other top-tier

backgrounds. But what defines us is not our degrees—it’s our refusal to compromise on quality, performance, or privacy.

What are we building?

WrkTalk is the world's first zero-access, zero-spam enterprise communication product that operates on a structural privacy architecture. One that’s already earned the trust of large enterprises like L&T Finance, Adani Group, and Kalyan Jewellers – just to name a few of our enterprise clients. This is not an MVP. This is production-grade software that secures communication for thousands—and soon, millions—of professionals worldwide.

What’s the role?

• Design and build blazing-fast, secure APIs using NestJS and Golang
• Architect robust microservices that scale and perform under pressure
• Engineer real-time communication using WebSockets, WebRTC, and mediasoup
• Optimize and tune PostgreSQL and Redis for lightning-fast access and reliability
• Lead Dockerized deployments and manage Kubernetes clusters
• Collaborate with our high-performance team of frontend devs, DevOps, and product leaders to ship elite-quality code
• Build for zero-trust environments—because no data should ever leak

The tech here is serious.

We work on socket-driven comms infrastructure, distributed control towers, multi-category encryption, root detection, app kill-switches, dynamic guest access, device-level lockout, and OOO / DND logic layered with smart whitelisting. This is not lightweight app dev. This is protocol-layer decision-making.

Where are we located?

We’re based in Navi Mumbai and building for the world.
