The Role

As a full-stack Software Engineer III on our Satori AI Platform team, you will be building the interfaces and APIs that our Fortune 500 customers use to deploy, monitor, and control AI security agents across their environments - and to understand exactly what those agents are doing on their behalf.

The primary focus of this position is frontend engineering with React and its surrounding ecosystem, but the workload spans our entire stack: rich web interfaces that stay fast while visualizing large volumes of usage, cost, and forecasting data; the middle-tier API surface that powers those interfaces; and the automation that deploys and monitors your work. We regularly put prototypes in front of customers to validate ideas mid-flight, so you can't just heads-down code in a vacuum. This is a uniquely challenging role: we empower small teams to make large impacts, the scale of our event data is legitimately huge, and we're building product that is mission-critical to our customers 24/7/365.

Your day-to-day

• Participate in customer feedback sessions to understand customer needs and build products customers are genuinely excited to use

• Design and build React interfaces used by large enterprise customers that are clean, accessible, and actually usable — not just feature-complete

• Turn dense data (usage metering, credit balances, spending caps, consumption forecasts, agent lifecycle state) into visualizations and workflows that communicate clearly at a glance

• Build and evolve the API routes that power your interfaces, and shape the contracts between front end and back end

• Tune performance across the stack — time to first interaction, render performance over large datasets, API response times, and payload size

• Debug production issues that span the browser, the API tier, and our cloud-based data platform

• Write automation that deploys and monitors your systems in the cloud

• Continually ship and test your work; learn new techniques through peer review and mentorship, and share what you learn with your peers

What you bring to the team

• A passion not just for development, but for the end-user experience - you sweat the details customers feel

• An ability and desire to reason through customer feedback and quickly validate prototype solutions

• A high bar for your code's design, testability, and performance

• Strong experience building applications with React and modern front-end tooling (TypeScript, a modern build/bundler toolchain, component and state management patterns, and automated testing)

• Solid command of the web platform fundamentals: HTML, CSS, and JavaScript

• Experience building and consuming APIs, and comfort working at least one layer into the back end that serves your UI

• Experience presenting large or complex datasets in the browser (data visualization, virtualization, pagination, or streaming) with an eye on performance

• Experience debugging production problems that span multiple stack components

• A B.S. or M.S. in Computer Science (or equivalent experience)
