Staff Software Engineer (Frontend)

Job Title : Staff Software Engineer (Frontend)

Location : Bengaluru, IN

About the Role :

As a Staff Frontend Engineer, you will be a technical leader and architect for 6sense products. You will bridge the gap between complex data-driven requirements and high-performance user interfaces. This role is for a visionary engineer who can build sophisticated frontend abstractions, define best-class engineering standards, and work as a peer to Product Design to deliver world-class AI-driven experiences.

What will you own :

• Product Collaboration: Work closely with Product Designers to translate high-fidelity designs into fluid, responsive, and accessible 6sense products.
• Systemic Abstractions: Design and build efficient, reusable frontend abstractions and systems that empower the entire engineering team to build faster and more consistently.
• Performance & Optimization: Proactively identify and resolve performance bottlenecks (e.g., rendering lag, bundle size, data-fetching efficiency) to ensure a premium user experience.
• Performance Engineering: Define and monitor Core Web Vitals. Solve complex performance bottlenecks related to bundle size, rendering patterns (SSR/ISR), and browser memory management.
• Technical Governance: Lead design and code reviews with a focus on long-term maintainability. Identify, document, and communicate frontend best practices across the organization.
• Cross-Pollination: Actively interact with other team members to incorporate their innovations into the front-end ecosystem and vice versa, fostering a culture of continuous improvement.
• Quality Leadership: Oversee the testing strategy, ensuring robust coverage across unit, integration, and E2E layers.
• Mentorship & Influence: Conduct high-level code reviews, write RFCs, and mentor Senior/Lead engineers. Influence the broader engineering organization's roadmap.
• Modern Standards: Stay at the forefront of the ecosystem (e.g., React Server Components, AI-augmented development) and strategically decide when to adopt new technologies.
• Leverage generative AI and AI coding tools to accelerate developer productivity, engineering workflows, and automation of repetitive tasks

Our Frontend Stack:

• Framework & Language: React + TypeScript
• Testing: Playwright (E2E) + Jest (Unit/Integration)
• Styling: CSS / SCSS / CSS Modules
• Component Documentation: Storybook

What we're looking for :

• Staff-Level Expertise: Extensive experience (10+ years) in frontend engineering, with a mastery of React and TypeScript.
• Architectural Thinking: Proven ability to build "internal products" (libraries, hooks, components) used by other developers.
• Testing Mastery: Deep experience with Playwright for resilient E2E flows and Jest for comprehensive unit testing.
• Styling & Design Systems: Expert knowledge of CSS/SCSS and CSS Modules. Experience using Storybook to maintain and scale a living design system.
• Analytical Mindset: Ability to profile browser performance and optimize complex React component trees.
• Communication: Exceptional ability to articulate technical trade-offs to both engineers and designers.
• Understanding of AI-native software development practices, including automated code generation, AI-driven testing, and human-in-the-loop review systems
• Proven ability to adopt and drive modern engineering paradigms, particularly integrating AI into development workflows to improve productivity, quality, and delivery speed
