Job description

SiftHub is an Agentic Platform for Deal Orchestration. We deploy agents to automate sales collateral, deal briefs, RFPs, and post-meeting follow-ups; unblocking deals for sales and solutions teams.SiftHub collates and sifts through your ecosystem (Drive, Gong, CRM, Slack, and more) to identify and convert real-time deal signals into tailored content and ready-to-execute actions. Designed to replicate how top-performing reps execute deals. Trusted by revenue teams at Saviynt, Everlaw, Allego, Superhuman, Sirion and more.

Why This Role Exists

SiftHub reaches users across multiple surfaces, a web app, a Chrome extension that surfaces AI intelligence mid-call and mid-workflow, a Microsoft add-in for Office users, and a Chrome extension for Google Sheets. The frontend experience is the product. We need an engineer who can own it across all of these: architecture, performance, and the bar enterprise users will hold us to.

What You'll Own

The SiftHub Chrome extension, Microsoft add-in, and React/TypeScript web application layer — architecture, performance, reliability, and cross-surface compatibility (including Chrome extension APIs, Office add-in constraints, Google Sheets integration, and web app parity)

Component systems and design token infrastructure that the team builds on

Frontend performance: load times, rendering, memory, and extension lifecycle

Collaboration with NLP and Backend engineers to integrate AI outputs into clean, responsive UIs

Code quality bar: reviews, patterns, and technical standards for the frontend team

Must-have:

• Bachelor’s or Master’s degree in Computer Science or a related field, or equivalent practical experience
• 1-3 years of production experience with React and TypeScript
• Strong understanding of modern frontend stack including React, TypeScript, Redux or Flux, Webpack, and testing frameworks such as Jest, Mocha, Enzyme, or React Testing Library
• Strong opinion on component design and state management, with the ability to reason about trade-offs and not just implement
• Experience with performance profiling and optimization in production environments
• Writes tests as a core part of development, not as an afterthought
• Strong grasp of UI principles with the ability to build clean, accessible, and maintainable interfaces, and clearly articulate design decisions

Good to have:

• Experience with content scripts, background workers, and extension messaging patterns
• Experience working with AWS and CI/CD tools such as GitHub Actions
• Experience at a B2B SaaS company with an understanding of enterprise UI expectations
• Exposure to AI or LLM-powered product surfaces

Who You Are

• You care about the last 5%, the micro-interactions, edge cases, and polish that separate good from great
• You push back on UX decisions when something does not feel right, and you have the design intuition to back it up
• You are energised by the ambiguity of early-stage product and can build a path when there is not one
• You take ownership end to end, from design review to production monitoring
• You communicate clearly across disciplines and can work effectively with designers, PMs, and backend engineers

What We Offer

• Work on genuinely hard AI problems, not CRUD apps
• Direct access to founders
• Access to best-in-class dev tools and AI assistants to help you do your best work
• Health insurance
• In-office in Mumbai, we value building together in person
