Principal Software Engineer - UI

About the Position

We are seeking a Principal Software Engineer - UI to join our team in Hyderabad. This role involves defining and owning the long-term architecture of a server-rendered web component platform that powers AI-native user experiences across our product. You will be responsible for making key decisions on rendering, component runtime, design systems, and streaming UX for AI-generated content, ensuring the experience layer remains resilient and coherent as the platform scales.

Responsibilities

• Platform Architecture & Strategy: Define and own the long-term architecture of a server-rendered web component platform.
• Rendering & Performance: Own end-to-end experience performance, including server-side rendering, streaming HTML, hydration correctness, and time-to-interactive.
• AI-Native Intelligent Experiences: Build platform primitives for agentic backends, including recommendations, autonomous triage, generated insights, and multi-step agent reasoning.
• Secure, Scalable Runtime: Design how the platform runs in production on Kubernetes, ensuring sandboxed execution, multi-tenant isolation, secure credential propagation, and observability.
• Developer Platform & Ecosystem: Shape the component model, data-loading APIs, design system, tooling, and guardrails for application development on the platform.
• Agentic Pipeline Awareness: Collaborate with ML and platform teams to translate backend capabilities into usable, safe, and trustworthy UX patterns.
• Business Alignment: Tie platform and experience architecture to business goals, ensuring engineering velocity, experience quality, and AI-native feature adoption support customer acquisition, retention, and time-to-market.
• Hands-on Engineering: Write high-performance, production-grade code and debug the hardest problems yourself.
• Cross-functional Execution: Drive business-critical platform outcomes in collaboration with ML, backend platform, SRE, security, UX, and product teams.
• Engineering Culture: Mentor senior and staff engineers, lead architecture reviews, and build a culture of rapid, impact-driven innovation.
• Ownership & Initiative: Identify platform and experience gaps, propose solutions, align stakeholders, and own execution.

Requirements

• Core Skills:

  • Deep expertise in web platform internals: Web Components, Shadow DOM, server-side rendering, streaming, module loading, and browser performance.
  • Strong server-side JavaScript/TypeScript engineering skills: Node.js, HTTP/2, proxies, V8 memory behavior, and isolate or worker-based execution models.
  • Hands-on experience running latency-sensitive services on Kubernetes, including resource management, rollout strategies, Helm, and production observability.
  • Strong web security fundamentals: session and token handling, egress control, sandboxing of untrusted code, and trust boundaries in multi-tenant systems.
  • Experience designing frameworks, SDKs, or design systems adopted by many teams, including versioning, backward compatibility, and migration strategy.
  • A track record of connecting platform and UX decisions to business outcomes such as adoption, retention, and time-to-market.

• Good to Have:

  • Prior experience in distributed systems performance and scalability, or in large-scale Node.js fleet operations.
  • Open-source contributions to major web frameworks, SSR tooling, build systems, design systems, or agent-framework projects.
  • Experience with enterprise SaaS platforms and their extensibility and customization models.
  • Prior startup experience working closely with Product and Growth teams in an early-stage environment.

We Offer

• Competitive salary and benefits
• Opportunity to work in a dynamic and innovative environment
• Collaborative and inclusive company culture
• Professional growth and development opportunities
