Job summary

Sift is hiring a product engineering leader to build Sift Agents, AI-powered frontend experiences for hardware teams. You’ll own features from MVP to production, talk to customers, and design interfaces that render agent insights over large telemetry in real time.

You’ll work on high-performance web apps using React, TypeScript, and modern CSS, collaborating with backend engineers to define API surfaces while delivering fast, polished UX across dashboards and chat interactions.

Qualifications

3+ years of professional software engineering experience.
Experience building high-performance web apps with React/TypeScript.
Experience shipping products with frontend UX polish.
Curious about AI products and agents.

Responsibilities

Talk directly to customers and partner with product to turn real review workflows into agent capabilities: generating dashboards, writing analysis scripts, and surfacing insights buried in their telemetry
Build the frontend surfaces where Sift Agents live, and make them feel great
Design the interaction patterns of agentic UX: streaming responses, long-running tasks, interruptions, and showing an agent’s work so engineers can trust it
Render an agent’s findings alongside the telemetry that backs them, and keep it fast even when the data is large
Push the browser to its limits when the data demands it: Web Workers, OPFS-backed caching, and stepping outside React when the framework becomes the bottleneck
Contribute to the component library to keep agentic UI patterns consistent across the product
Collaborate with backend and full stack engineers on the API design that powers agent sessions
