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.
Qualifications
Professional Timeline: 12–14 years of progressive software engineering experience building and scaling full-stack applications in high-growth product teams.
Scale & Iteration History: A proven track record of building complex systems from scratch and steering them through multiple scale iterations in live production environments.
Pragmatic Delivery: Skilled at balancing rapid feature delivery with long-term code maintainability, clean documentation, and scalability.
Collaborative Leadership: Demonstrated experience managing large-scale technical initiatives, coordinating cross-functional engineering loops, and mentoring other engineers.
Education Baseline: Degree in Computer Science, Engineering, or a related quantitative technical field.
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.
