Lead Back End Engineer

This is a leadership role in our engineering team – not just a cog in the wheel.
This is not a “maintenance” role. This is engineering leadership—owning the backend architecture of a global, privacy-first communication platform. You’ll lead by example, guide a high-calibre team, and ensure our backend systems remain blazing-fast, rock-solid, and uncompromising on security. You’ll be at the intersection of code and leadership—mentoring engineers, driving architectural decisions, and setting engineering standards that define how a global product is built.
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?
• Architect backend systems in NestJS and Golang to meet global scale and enterprise-grade performance.
• Drive design for microservices, real-time comms (WebSockets, WebRTC), and data stores (PostgreSQL, Redis).
• Lead code reviews, enforce coding standards, and maintain CI/CD discipline.
• Mentor and upskill backend engineers.
• Collaborate cross-functionally with frontend, DevOps, and product leaders.
• Own technical problem-solving—anticipate bottlenecks, make hard calls, and prevent tech debt from being parked for “later.”
• Manage task allocation, workflow discipline, and ensure smooth collaboration with frontend and DevOps.
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.
Who should apply?
• 6–8+ years in backend engineering, with at least 2 years in a leadership role.
• Expertise in Golang and Node.js (NestJS).
• Strong database tuning skills (PostgreSQL, Redis).
• Solid understanding of Docker, Kubernetes, and scalable deployment.
• Experience building real-time systems at scale.
• Proven ability to lead technical discussions and inspire engineering teams.
• Track record of shipping production-grade, high-performance systems.
Why should you join?
• Because you want to own backend architecture—not just follow it
• Because you’ll work directly with established founders, not buried under layers
• Because you’ll ship real, deeply engineered features used by large number of enterprise users
• Because you’ll grow 10x faster here—in experience, learning, and impact
• And because if you walk this road with us for 3–4 years, it’ll catapult you into a tech orbit or fame and glory you never imagined
Where are we located?
We’re based in Navi Mumbai and building for the world.
