Senior Staff Software Engineer - Full Stack

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.

Fresh vision. Real impact. Come build it with us.

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.
