Staff Backend Engineer

Details

As a Staff Backend Engineer on the Self-Hosted team, you will build and maintain backend services that power SentinelOne's on-premises deployments. You will work across a Go- and Python-based microservices platform, ensuring that enterprise customers can deploy, operate, and upgrade SentinelOne in air-gapped and restricted environments. Your work will directly determine the reliability of security infrastructure for large organizations.

Responsibilities

• Design and develop backend services in Go and Python using Flask, SQLAlchemy, and gevent for customer-managed environments, with a strong focus on operational correctness and upgrade safety.
• Own the deployment lifecycle by building and maintaining Docker images and ensuring services start correctly across diverse customer infrastructure configurations.
• Build and evolve REST and gRPC APIs consumed by internal services and external management consoles while maintaining strict backward-compatibility contracts.
• Work with PostgreSQL and MongoDB to write Alembic migrations that run safely in production, support schema evolution without downtime, and maintain query performance under load.
• Improve observability by instrumenting services with OpenTelemetry, defining service-level objectives, and enabling operators to diagnose issues in environments where SentinelOne has limited visibility.

Requirements

• 8+ years of backend engineering experience with Go in a production microservices environment.
• Deep familiarity with Flask, SQLAlchemy, and asynchronous concurrency patterns such as gevent or asyncio.
• Hands-on experience packaging and deploying containerized services with Docker and Kubernetes.
• Experience 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, including structured logging, distributed tracing with OpenTelemetry or equivalent tools, and dashboard development in Grafana or similar tools.
