As a Senior Staff Software Engineer you will be tasked with owning the architecture of SentinelOnes self-hosted (on-prem) Endpoint Protection platform across multiple teams a distributed mission-critical security system deployed inside customer-controlled enterprise government and regulated environments. You will set the standard for how the platform achieves high availability scalability and reliability on infrastructure we dont operate ourselves while influencing the engineering roadmap for the product this role you will act as a recognized subject-matter expert who reviews and elevates the work of other senior engineers and drives complex cross-team designs to completion.

Primary responsibilities include:

• Own and evolve the architecture of the self-hosted platform across multiple teams backend services data pipelines control logic and the deployment topology shipped to customers (containerized microservices on bare metal delivered as an appliance/OVA) and implement improvements to existing architecture.
• Set the standard for high availability and resilience in customer-controlled deployments: clustering replication failover consensus/leader election and graceful degradation across single-node and multi-node topologies and drive infrastructure cost analysis and optimization.
• Define scalability and capacity-planning strategies that hold across a wide range of customer scale and hardware and establish frameworks for performance observability and operational excellence in constrained and air-gapped environments.
• Lead the translation of SaaS/cloud-native capabilities into on-prem architecture refine vaguely specified complex requirements into robust future-proof end-to-end designs and define coding patterns and standards that span multiple teams.
• Influence the engineering roadmap drive medium-to-large initiatives that span teams mentor staff and senior engineers and act as a cross-team technical authority sought out to review the work of others.

Ideal candidates will have:

• A degree in Computer Science or Software Engineering or equivalent experience with roughly 8 years of related experience and deep hands-on expertise in Go and/or Python across technologies such as PostgreSQL MongoDB Redis Kafka Docker and Linux.
• Extensive proven experience designing and delivering on-prem / self-hosted / customer-deployed software including packaging and lifecycle for customer-controlled environments (appliance/OVA bare-metal or containerized deployments upgrades and air-gapped or restricted networks).
• A strong track record architecting distributed systems for high availability and fault tolerance in on-prem / customer-controlled deployments replication clustering failover consensus/leader election and being recognized as a subject-matter expert in one or more of these areas.
• Deep command of scalability and performance in on-prem deployments: horizontal/vertical scaling sharding/partitioning load balancing capacity planning and evaluating technology trade-offs and costs across customer-controlled hardware and environments.
• The ability to take vaguely specified complex requirements and create efficient robust future-proof end-to-end designs across teams; experience influencing a roadmap and leading multi-team designs; and excellent communication and mentoring skills. Experience with security products is a strong advantage.

AI is redefining how the world operates and rewriting the rules of security in real time and SentinelOne was built for this moment. From day one we architected an AI-native platform designed to operate at machine speed not as an add-on to legacy systems but as the foundation itself. If you want to build where innovation and impact move together this is that place.
