Staff Backend Software Engineer, On-prem

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.
