## Description

We're looking for a Senior Software Development Engineer to be a technical leader on the Kiro Web team. You'll own the full-stack architecture of a system that's genuinely novel: a web application that orchestrates teams of AI agents collaborating on code in real time, with dynamic topology control, inter-agent communication, streaming visual interfaces, and tool approval workflows - all built on the Agent Client Protocol (ACP).

You'll make the hard architectural decisions: how to scale the process-per-session model as users run dozens of concurrent agents, how to design the state synchronization between server-side ACP processes and browser-side React stores, how to architect the multi-agent team orchestration layer so that agents can dynamically activate/deactivate teammates and modify communication topologies at runtime, and how to build enterprise features (multi-tenant, RBAC, usage metering) without compromising the localhost-first simplicity that makes Kiro Web fast and ergonomic.

Your influence will define the team's technical trajectory. You'll mentor engineers across the full stack, lead design reviews, drive cross-team initiatives with the Kiro CLI and Kiro IDE teams, and translate ambiguous product requirements into concrete systems. When novel problems emerge - and they will, because multi-agent orchestration UIs are a new category - you'll be the one who designs the solution.

This is your chance to lead the engineering that powers the agent that builds the future., Kiro Web builds the browser-based experiences and orchestration platform for Kiro. We own: (1) Kiro Web - a full-featured local web application for managing AI coding agent sessions with real-time streaming, multi-agent team orchestration, dynamic topology control, tool approval, diff views, and session resume, (2) the kiro.dev public portal (downloads, docs, changelog, pricing on Harmony), and (3) emerging enterprise console experiences. Our stack: React 19, TypeScript, Vite, Fastify, Node.js 22, TailwindCSS v4, Zustand, WebSockets, JSON-RPC 2.0, pnpm monorepo. We're ~15 engineers between Seattle and Portland building a genuinely new category of developer tool interface.
