Senior Staff Software Engineer - Full Stack

At Freshworks, we don’t just ship software—we shape it to be fast, reliable, and refreshingly simple. As a Senior Staff Software Engineer - Full Stack , you will serve as a premier technical leader architecting the end-to-end systems that drive our global SaaS products. In this role, you will masterfully balance complex distributed backend infrastructure with highly responsive, scalable frontend applications, leading cross-functional technical strategies and mentoring engineers to level up our entire platform ecosystem. If you obsess over time and space complexity, love breaking down tough, multi-tier architectural problems, and take pride in leading technical execution without losing touch with the code—you’ll feel right at home. Impact You Can Create E2E Platform Evolution: Own and scale foundational full-stack architectures capable of handling millions of transactions while delivering seamless, high-performance web experiences globally. Technical Guidance: Act as a definitive technical compass across multiple engineering tracks, translating ambiguous product visions into resilient, modular high-level and low-level designs. Engineering Multiplier: Foster a culture of excellence across the org by leading deep-dive code reviews, mentoring junior/mid-level systems engineers, and introducing modern architectural patterns. AI-Powered Efficiency: Pioneer the integration of modern AI tools (e.g., GitHub Copilot) into the daily full-stack development workflow to accelerate delivery without sacrificing technical depth. Roles & Responsibilities Full-Stack Architecture: Architect, build, and maintain scalable backend microservices and extensible REST APIs paired with intuitive, modular frontend application layers. Full Lifecycle Ownership: Own the entire software development lifecycle—from gathering functional/non-functional requirements and data modeling to deployment, automation, and live production support. Code & Design Optimization: Write clean, modular, and testable code optimized for browser rendering efficiency, database execution performance, and space/time complexity. Production Governance: Ensure backend and frontend systems are tuned for high availability (99.99%+), multi-tenant fault tolerance, security compliance, and deep observability. Cross-Functional Partnership: Collaborate closely with Product Managers, UI/UX designers, and Site Reliability Engineers (SREs) to ship highly localized, value-driven capabilities fast. Root-Cause Analysis: Troubleshoot complex full-stack performance bottlenecks in production, from slow database queries to state-management memory leaks. Mentorship & Best Practices: Lead comprehensive architectural reviews, establish development roadmaps, mentor 2–4 engineers, and actively drive OOPS and SOLID design principles across the organization.

Skills Computer Science Foundations: Expert-level grasp of Data Structures & Algorithms (DSA), time/space complexity trade-offs, and Object-Oriented Design (OOD) anchored in SOLID principles. System Design (HLD & LLD): Proven capability to design scalable, highly available, and fault-tolerant end-to-end multi-tenant systems, including APIs, web architectures, schemas, and data models. Distributed Infrastructure Stack: Solid exposure to RDBMS, NoSQL, caching strategies, microservices architecture, and distributed queuing systems. Modern Web Ecosystems: Strong understanding of frontend engineering paradigms, including component lifecycles, state management, and client-side performance optimization. Cloud & DevOps Practice: Hands-on experience working with CI/CD automation pipelines, DevOps tooling, and cloud infrastructure platforms (AWS or GCP). AI Tool Fluency: Practical exposure and experience using generative AI tools to improve day-to-day coding efficiency and technical exploration. Technical Communication: Exceptional logical reasoning with the ability to clearly articulate complex technical thought processes and designs to both engineers and executives
