Role
Who you are
- 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
What the job involves
- We’re looking for people who are relentlessly curious and committed to continuous learning
- AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts
- Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes
- As a Staff Backend Engineer on the Self-Hosted team, you will be tasked with building and maintaining the backend services that power SentinelOne's on-premises deployments
- You will work across a Python-based microservices platform, ensuring that enterprise customers can deploy, operate, and upgrade SentinelOne in air-gapped and restricted environments
- Your work directly determines the reliability of security infrastructure for some of the largest organizations in the world
- 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
Our take
Cybercriminals are now leveraging the power of automation to make the current threat landscape too advanced for a lot of legacy antivirus software. SentinelOne is a cybersecurity company that matches this automation with machine learning-focused software designed to help businesses defend against online attacks.
The company expanded the scope of its business from the endpoint security market to three markets valued at a combined $30 billion, including the corporate endpoint security and IT operations management markets. This gives SentinelOne a bigger potential customer base, although it also puts them in direct competition with more focused cybersecurity companies, in addition to its biggest competitor, CrowdStrike.
When the company went public in 2021, it made financial headlines as the highest-valued cybersecurity IPO ever, which gave SentinelOne a market capitalisation of $10 billion. However, it's since fallen to around $ 4 billion. It has subsequently launched S Ventures, a $100M fund, through which SentinelOne invests in cybersecurity startups and has expanded its partnership with major tax firm KPMG to accelerate cyber investigations and responses to threats.
