Essential requirements and candidate background

• To be successful in this role you have:
• 15+ years of software engineering experience, focused in frontend or web platform engineering at a high-growth tech company or top-tier AI lab
• Deep expertise in web platform internals: Web Components and Shadow DOM, server-side rendering and hydration, streaming, module loading, and browser performance
• Production experience with Lit.js, React, or comparable frameworks, and a clear view of the tradeoffs between them
• Server-side JavaScript/TypeScript engineering skills: Node.js, HTTP/2, proxies and streaming, 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
• Web security fundamentals: session and token handling, egress control, sandboxing of untrusted code, and trust boundaries in multi-tenant systems
• Has shipped intelligent, AI-driven user experiences (not just consumed an LLM API), with intuition for how agent and model output should surface to real users
• Experience: agentic or multi-agent systems from the consumer side
• Understands agent orchestration, tool-calling protocols (MCP or equivalent), and reasoning traceability well enough to design UX and platform primitives around them
• 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, not just technical metrics
• Self-driven with ownership: able to identify gaps, propose solutions, align stakeholders, and execute at startup pace

Preferred experience and additional strengths

• 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: enterprise SaaS platforms and their extensibility and customization models
• Prior startup experience working closely with Product and Growth teams in an early-stage environment

Location, schedule and contract conditions

• Work arrangement: Hybrid
• Advertised location: Hyderabad, India

Benefits mentioned by the employer

• Platform Architecture & Strategy — Define and own the long-term architecture of a server-rendered web component platform that powers AI-native user experiences across the product
• You'll make the key decisions on rendering, component runtime, design systems, and streaming UX for AI-generated content, and keep the experience layer resilient and coherent as the platform scales
• Rendering & Performance — Own end-to-end experience performance: server-side rendering, streaming HTML, hydration correctness, and time-to-interactive
• Push the state of the art in server rendering of web components so experiences are fast, deterministic, and consistent between server and client
• AI-Native Intelligent Experiences — Build the platform primitives product teams use to expose agentic backends to end users, including recommendations, autonomous triage, generated insights, and multi-step agent reasoning
• Own the hard UX problems specific to AI-native products: streaming model output, progressive disclosure of agent reasoning, graceful handling of latency and uncertainty, and human-in-the-loop review flows that make autonomous behavior legible and controllable
• Developer Platform & Ecosystem — Shape the component model, data-loading and context APIs, design system, tooling, and guardrails that let many teams build applications on the platform
• Make the right path the easy path
• Agentic Pipeline Awareness — Work closely with ML and platform teams building agent orchestration and tool-calling infrastructure (multi-agent dispatch, MCP-style tool integration, reasoning traceability)
• Translate what those backends can do into UX patterns that are usable, safe, and trustworthy
• Business Alignment — Tie platform and experience architecture to business goals, so that engineering velocity, experience quality, and adoption of AI-native features support customer acquisition, retention, and time-to-market
• Hands-on Engineering — Write high-performance, production-grade code across the experience stack (TypeScript, Lit.js / Web Components, Node.js, modern build tooling) and the runtime stack (Kubernetes, containerized services)
