Job summary

Proofpoint is seeking a full-time, senior Frontend/Full-stack Software Engineer III to join the Satori AI Platform team. You will craft React interfaces and robust APIs used by Fortune 500 customers to deploy and monitor AI security agents.

The role emphasizes frontend engineering with React/TypeScript while touching the middle tier and automation, enabling scalable, mission-critical applications for large deployments.

Qualifications

• 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).
• Experience building and consuming HTTP/REST APIs, and comfort working at least one layer into the back end that serves your UI.
• Experience debugging production problems that span multiple stack components.
• A B.S. or M.S. in Computer Science (or equivalent experience).

Responsibilities

• 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.
• Participate in customer feedback sessions to understand customer needs and build products customers are genuinely excited to use.
• Write automation that deploys and monitors your systems in the cloud.

Job description

Proofpoint is a global leader in human- and agent-centric cybersecurity. We protect how people, data, and AI agents connect across email, cloud, and collaboration tools. Over 80 of the Fortune 100, 10,000 large enterprises, and millions of smaller organizations trust Proofpoint to stop threats, prevent data loss, and build resilience across their people and AI workflows. Our mission is simple: safeguard the digital world and empower people to work securely and confidently. Join us in our pursuit to defend data and protect people.

How We Work:

At Proofpoint you’ll be part of a global team that breaks barriers to redefine cybersecurity guided by our BRAVE core values:

Bold in how we dream and innovate

Responsive to feedback, challenges and opportunities

Accountable for results and best in class outcomes

Visionary in future focused problem-solving

Exceptional in execution and impact

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.
