Job description

Our Purpose

At SentinelOne, we are driven by a clear purpose: to give the advantage to those who secure our future. As AI reshapes how organizations build, operate, and innovate, the responsibility to protect them becomes more critical than ever. When you join SentinelOne, your work helps protect global enterprises, critical infrastructure, and the technologies shaping tomorrow. 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 Staff Backend Engineer on the Self-Hosted team, you will be tasked with building and maintaining the backend services that power SentinelOne's on-premises deployments. You will work across a Python-based microservices platform, ensuring that enterprise customers can deploy, operate, and upgrade SentinelOne in air-gapped and restricted environments. Your work directly determines the reliability of security infrastructure for some of the largest organizations in the world.

What Will You Do?

Primary responsibilities include:

Design and develop backend services in Python (Flask, SQLAlchemy, gevent) that run in customer-managed environments, with a strong focus on operational correctness and upgrade safety.
Own the deployment lifecycle: build and maintain Docker images, and ensure services start correctly across a wide range of customer infrastructure configurations.
Build and evolve REST and gRPC APIs consumed by both internal services and external management consoles, maintaining strict backwards-compatibility contracts as the platform scales.
Work closely with the database layer (PostgreSQL and MongoDB) to write Alembic migrations that run safely in production, handle schema evolution without downtime, and keep query performance healthy under load.
Drive observability improvements by instrumenting services with OpenTelemetry, defining SLOs, and making sure operators can diagnose issues in environments where SentinelOne has limited visibility.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

8+ years of backend engineering experience with Python in a production microservices environment, including deep familiarity with Flask, SQLAlchemy, and async concurrency patterns (gevent or asyncio).
Hands-on experience packaging and deploying containerized services with Docker and Kubernetes, including writing Helm charts and reasoning about upgrade paths across multiple deployed versions.
Strong PostgreSQL skills including schema design, query optimization, and writing zero-downtime migration scripts using Alembic or equivalent tools.
Experience building and maintaining gRPC and REST APIs with explicit versioning strategies, preferably in environments where breaking changes are costly.
Solid understanding of observability: structured logging, distributed tracing with OpenTelemetry or equivalent, and building dashboards in Grafana or similar tools.

Why SentinelOne?

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.
