Senior Software Engineer I/II - Infrastructure

Samsara is hiring a Senior Engineer in its Infrastructure organization to evolve the cloud foundations supporting its products. The role focuses on building reliable, scalable, resilient, and cost-efficient cloud platforms and infrastructure automation, while reducing production risk and enabling product engineering teams.

Responsibilities:

• Set technical direction for major infrastructure systems and lead ambiguous initiatives spanning multiple teams
• Design, build, and operate reliable cloud platforms, bringing depth in one or more areas such as compute, networking, storage, stateful systems, or infrastructure control planes
• Improve the scalability, capacity management, isolation, recovery, and cost efficiency of critical production infrastructure
• Build standardized infrastructure-as-code workflows and reusable automation that support self-service provisioning, testing, progressive rollout, reconciliation, rollback, and drift prevention
• Identify shared failure modes and build safeguards that prevent localized failures from escalating into broad customer impact
• Contribute to multi-account, multi-region, and isolated AWS architectures, including regulated environments such as GovCloud
• Participate in operational ownership and incident response, using incidents and near misses to drive durable architectural improvements
• Mentor engineers, raise the quality of infrastructure design and operational judgment, and establish patterns that can be adopted across the organization
• Clearly communicate architecture, trade-offs, risks, and migration plans to technical and organizational stakeholders
• Champion, role model, and embed Samsara’s cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team) as we scale globally and across new offices

Requirements:

• 6+ years of experience designing and building software, infrastructure, or distributed systems, including operating critical systems in production
• Deep expertise in at least one of the following: compute and workload orchestration, networking, storage and stateful systems, or cloud infrastructure control planes
• Strong software-engineering fundamentals in Go, Python, Java, or a similar language
• Hands-on experience designing and operating infrastructure on a major public cloud platform
• Experience using infrastructure as code, such as Terraform, to safely manage production infrastructure
• Strong understanding of capacity management, failure domains, observability, rollout safety, and production recovery
• Demonstrated ability to lead complex technical initiatives across teams and through ambiguous problem spaces
• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• AWS experience
• Designing and operating large-scale compute or container platforms such as ECS, EKS, Kubernetes, or similar orchestration systems
• Designing and operating stateful distributed systems such as Kafka, OpenSearch, managed databases, caching, or large-scale storage platforms
• Building internal infrastructure platforms, control planes, or self-service developer experiences adopted across multiple teams
• Designing multi-account or multi-region cloud architectures with strong workload isolation and disaster recovery
• Leading major infrastructure migrations while maintaining availability and controlling operational risk
• Delivering measurable improvements in infrastructure capacity, cost efficiency, or developer self-service
