Pragmatike is hiring on behalf of a fast-growing AI startup recognized as a Top 10 GenAI company by GTM Capital , founded by MIT CSAIL researchers.
We are searching for a Senior UI / Frontend Engineer with strong, hands‑on experience building high-quality, high-performance user interfaces for complex, data-intensive AI products used by Fortune 500 customers.
This role is ideal for an engineer who cares deeply about UX, performance, and maintainable frontend architecture —someone who can own features end to end, collaborate closely with design and backend teams, and deliver polished, production‑ready interfaces at scale.
What Youll DoBuild and maintain modern, production‑grade web interfaces using React and TypeScript.
Translate product requirements and design systems into clean, scalable UI components.
Own complex frontend features end to end, from implementation to production support.
Optimize UI performance for large datasets, real‑time updates, and high‑usage dashboards.
Collaborate closely with product, design, and backend teams to ship user‑facing features.
Establish frontend best practices around state management, testing, and code quality.
Improve frontend architecture, tooling, and developer experience.
Debug and resolve production UI issues across browsers and devices.
5+ years of experience as a Frontend / UI Engineer.
Strong proficiency with React and TypeScript in production environments.
Solid understanding of modern frontend architecture and component‑based design.
Experience building responsive, accessible, and high‑performance user interfaces.
Familiarity with frontend build tools, bundlers, and CI/CD workflows.
Ability to collaborate effectively with designers and backend engineers.
Comfortable owning features and shipping to production.
Experience building data‑heavy dashboards or real‑time web applications.
Familiarity with modern state management solutions (Redux, Zustand, React Query).
Experience with design systems and component libraries.
Exposure to AI‑driven or ML‑powered products.
Startup experience or comfort working in fast‑moving, ambiguous environments.
Research pedigree: MIT CSAIL founders with deep AI and systems expertise.
Customer impact: Build interfaces used by Fortune 500 clients.
Industry momentum: Alumni behind major acquisitions (MosaicML Databricks, Run:AI NVIDIA, W&B CoreWeave).
Funding & growth: Oversubscribed seed round, next funding planned for 2026.
Ownership: Lead UI features for mission‑critical products.
Quality & craft: Work on frontend problems that prioritize performance and UX at scale.
