Staff Backend Engineer

Details

At SentinelOne you will build and maintain backend services that power on-premises (self-hosted) deployments. You will work on a Python-based microservices platform to ensure enterprise customers can deploy, operate, and upgrade SentinelOne in air-gapped and restricted environments. Work focuses on operational correctness, upgrade safety, and reliability for large organizations.

Responsibilities

• 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.

Requirements

• 8+ years of backend engineering experience with Python in a production microservices environment.
• 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.

Benefits

• Restricted Stock Units (RSUs) and Employee Stock Purchase Plan (ESPP)
• Flexible time off, paid company holidays, paid sick time, gender-neutral parental leave, and grandparent leave
• Medical, dental, and vision coverage; 401(k) with company match; life and disability insurance; FSAs
• Home office allowance and mobile phone reimbursement
• Wellness programs, fertility coverage, adoption & surrogacy reimbursement
