Staff Full - Stack Engineer (IC4)

At Freshworks, we don't just ship software; we shape it to be fast, reliable, and refreshingly simple. As a Staff Full-Stack Engineer (IC4), you will architect the end-to-end systems that drive our global SaaS products, balancing complex distributed backend infrastructure with highly responsive, scalable frontend applications. You will lead cross-functional technical strategies, champion engineering excellence across teams, and mentor 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.

Responsibilities:

• 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 (IC4): Act as a 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 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.
• 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 production support.
• Code and 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 and Best Practices: Lead architectural reviews, establish development roadmaps, mentor 2-4 engineers, and actively drive OOPS and SOLID design principles across the org.

Requirements:

• Computer Science Foundations: Expert-level grasp of Data Structures and Algorithms (DSA), time/space complexity trade-offs, and Object-Oriented Design (OOD) anchored in SOLID principles.
• System Design (HLD and 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 and 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.
• Professional Timeline: 10+ years of progressive software engineering experience building and scaling full-stack applications in high-growth product teams.
• Iterative Sourcing History: A proven track record of building complex systems from scratch and steering them through multiple-scale iterations in production.
• Pragmatic Delivery: Skilled at balancing rapid feature delivery with long-term code maintainability, clean documentation, and scalability.
• Collaborative Leadership: Experience managing technical initiatives, coordinating cross-functional engineering loops, and mentoring other engineers.
• Education Baseline: Degree in computer science, engineering, or a related quantitative technical field.
