Job summary

SentinelOne is seeking a Staff Backend Engineer for the Self‑Hosted team. You will build and maintain backend services in a Python microservices platform powering on‑prem deployments, with a focus on reliability in air‑gapped environments.

You will work across Flask/SQLAlchemy, Docker, Kubernetes, and databases like PostgreSQL and MongoDB. Strong emphasis on observability, migrations, and upgrade safety in enterprise settings.

Qualifications

• 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.

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.
