What are we looking for?

Join SentinelOne’s Endpoint Protection organization as the fullstack engineer who represents the macOS Agent team across our backend services and customer console. Your primary charter is to build and evolve the control plane, policy, and visibility experiences that power our macOS agent at scale; then surface them clearly in the UI. You’ll partner daily with macOS/Windows/Linux endpoint specialists while collaborating with cloud/platform engineers to ship reliable, low-latency agent-cloud interactions. You’ll be embedded in the Endpoint (macOS Agent) group and act as our full-stack lead for agent to cloud workflows. Prioritizing agent first, while partnering with cloud teams to deliver reliable services and intuitive console experiences.

What will you Do?

• Own agent–cloud workflows end-to-end. Design, implement, test, and ship features that configure, observe, and interact with macOS agents (policy management, live response, threat remediation, device posture, fleet operations). In this role, around 80% of your work would be focused on Backend (our primary language for new development is Golang, but you may also come across Python in our existing codebase), and 20% on Frontend (React + TypeScript for all new development).
• Craft clear customer insights. Turn raw endpoint telemetry and detections into actionable, explainable views and workflows in the console, enabling security teams to investigate and respond quickly.
• Contribute to the architecture. Get involved in designs for new modules spanning agent, services, and UI; choose patterns/technologies for scale, reliability, and performance; represent the endpoint perspective in reviews.
• Raise the bar on quality. Add robust automation, unit/component tests, and resiliency checks; drive safe rollouts, versioning, and backward compatibility for agent-facing APIs.
• Partner across disciplines. Work closely with product, customer support, and endpoint/kernel engineers; help triage production issues and translate field feedback into product improvements.

Your work will directly improve how some of the world’s largest organizations (including multiple Fortune 10, hundreds of Global 2000, and government customers) configure and control their endpoints, understand risk, and respond to threats- across millions of macOS devices.

What experience or knowledge should you bring?

• 4+ years of full-stack experience, with several years hands-on in Go and/or Python (or similar).
• Proven track record building microservices and cloud-native systems that run at scale with low latency.
• Experience with streaming/ingest and data pipelines; comfort with both SQL and NoSQL stores.
• Proficiency in a modern front-end framework (React/Angular + TypeScript).
• Hands-on with Docker and Kubernetes, and AWS and/or GCP.
• Strong product sense and the ability to translate requirements into resilient designs.
• Excellent communication; effective in hybrid/remote teams; experience leading cross-functional projects.
• Nice to have: Experience with Kafka ecosystem (Kafka Pub/Sub, Connect), gRPC/Protobuf.
• Nice to have: Security/EDR domain knowledge (threat modeling, detection/response, hardening).
