If you are motivated by meaningful challenges and want your impact to be real, measurable, and global, you will find purpose here.
About Us
SentinelOne is a company at the intersection of AI and security, pioneering a new operating model for cybersecurity. Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.
Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.
What Are We Looking For?
We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.
As a Senior Software Engineer - Agent (Endpoint Protection) Platform, you will design, develop, and operate highly available backend platform, engineered to process several millions of events per second. You will own the end-to-end lifecycle of high-volume data pipelines, ensuring mission-critical stability and data integrity through rigorous testing and proactive monitoring of key performance metrics. By continuously refining the codebase and optimizing for distributed scale, you will build the resilient backbone that allows SentinelOne’s platform to stay ahead of global cyber threats in real-time. As part of SentinelOne’s main product line - Endpoint Protection, we secure tens of millions of devices across the globe running all kinds of OS (Windows, Linux, macOS) and process billions of security events every day. You’ll be joining a team with a significant impact on how our customers’ environments (including 4 of Fortune 10 companies, hundreds of Global 2000, and public sector) are protected.
What will you do?
Primary responsibilities include:
Ideal candidates will have:
AI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself. If you want to build where innovation and impact move together, this is that place.
We invest in our Sentinels with comprehensive, competitive benefits designed to support you and your family:

What will you do?
Primary responsibilities include:
- Design, develop, implement, test, document, and operate large‑scale, high‑volume, low‑latency applications - such as e.g. policies, configurations and command distribution to millions of agents around the world (protection from SentinelOne installed on the devices), and an agent platform protocol for other teams to build upon and ship new security & detection capabilities safely and quickly.
- Improve reliability, scalability, and observability of agent fleet in production, ensuring customers and internal teams have real‑time insight into fleet health and coverage.
- Translate business and functional requirements into robust, scalable, operable solutions that work well within the overall data architecture.
- Participate and collaborate with cross functional teams in the organization to understand the business requirements and to deliver solutions that can scale.
- Maintain application stability and data integrity by monitoring key metrics and improving codebase accordingly.
- Understand & maintain existing codebase by regular re-factoring and applying requested fixes and features.
- Learn new technologies that can solve our huge volume of data and the challenges it poses.
- Your Toolkit: Our new components are primarily developed in Go and Java, and we use Python in our current backend environment. Communication between microservices is facilitated using gRPC, REST, GraphQL APIs, and Kafka, depending on specific requirements. We use Redis, PostgreSQL, Cassandra, ClickHouse and have our columnar time-series database for efficient event storage and retrieval at scale. Our services are deployed across multiple AWS/GCP regions with Kubernetes; among other tools, you'd also use Docker, GitHub and ArgoCD.
