About The Position

Organizations everywhere struggle under the crushing costs and complexities of “solutions” that promise to simplify their lives. To create a better experience for their customers and employees. To help them grow. Software is a choice that can make or break a business. Create better or worse experiences. Propel or throttle growth. Business software has become a blocker instead of ways to get work done. There’s another option. Freshworks. With a fresh vision for how the world works. Freshworks Inc. builds uncomplicated service software that delivers exceptional employee and customer experiences. Our people-first approach to AI eliminates friction, helping businesses reduce complexity, lower cost-to-serve, and deliver faster, more human support through enterprise-grade yet easy-to-use CX and IT solutions. Nearly 75,000 companies, including Bridgestone, New Balance, Nucor, S&P Global, and Sony Music, trust Freshworks to power their Employee Experience (EX) and Customer Experience (CX) operations. FireHydrant, a Freshworks company, extends this mission to modern engineering teams, helping them manage incidents, reduce downtime, and operate with confidence across organizations with cloud infrastructure, developer tooling, fintech, gaming, and e-commerce. At Freshworks, we don’t just ship software—we shape it to be fast, reliable, and refreshingly simple. As a Lead Backend Engineer, you’ll build the scalable systems that drive our global products—and do it with clarity, ownership, and a sharp eye for design. You’ll lead backend modules end-to-end, influence architecture across teams, and raise the bar on performance, stability, and code quality. If you obsess over time and space complexity, love breaking down tough problems, and take pride in helping others level up—you’ll feel right at home.
