Staff Backend Software Engineer (On-prem)

Join SentinelOne, a leading cybersecurity company, as a Staff Backend Software Engineer. In this role, you will be responsible for building and maintaining the backend services that power our on-premises deployments. You will work with 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 impact the reliability of security infrastructure for some of the largest organizations in the world.

• Concevoir et développer des services backend en Go (Flask, SQLAlchemy, gevent) qui fonctionnent dans des environnements gérés par le client, en mettant l'accent sur la correction opérationnelle et la sécurité des mises à niveau.
• Posséder le cycle de vie de déploiement : construire et maintenir des images Docker, et s'assurer que les services démarrent correctement dans une large gamme de configurations d'infrastructure client.
• Travailler en étroite collaboration avec la couche de base de données (PostgreSQL et MongoDB) pour écrire des migrations Alembic qui s'exécutent en toute sécurité en production, gérer l'évolution du schéma sans temps d'arrêt.
• We’re looking for people who are relentlessly curious and committed to continuous learning
• Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes
• 8+ years of backend engineering experience with Go 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
• Solid understanding of observability: structured logging, distributed tracing with OpenTelemetry or equivalent, and building dashboards in Grafana or similar tools
• Experience building and maintaining gRPC and REST APIs with explicit versioning strategies, preferably in environments where breaking changes are costly
