Senior Software Engineer I/II - Infrastructure

Who we are Samsara (NYSE: IOT) is the pioneer of the Connected Operations™ Cloud, which is a platform that enables organizations that depend on physical operations to harness Internet of Things (IoT) data to develop actionable insights and improve their operations. At Samsara, we are helping improve the safety, efficiency and sustainability of the physical operations that power our global economy. Representing more than 40% of global GDP, these industries are the infrastructure of our planet, including agriculture, construction, field services, transportation, and manufacturing — and we are excited to help digitally transform their operations at scale. Working at Samsara means you’ll help define the future of physical operations and be on a team that’s shaping an exciting array of product solutions, including Video-Based Safety, Vehicle Telematics, Apps and Driver Workflows, and Equipment Monitoring. As part of a recently public company, you’ll have the autonomy and support to make an impact as we build for the long term. About the role: As a Senior Engineer in the Infrastructure org, you will help evolve the cloud foundations behind every Samsara product. Your goal will be to reduce systemic production risk and enable continued growth by making infrastructure safer to change, easier to operate, and more resilient and cost-efficient at scale. You will bring deep expertise in at least one infrastructure domain, such as compute and workload orchestration, networking, storage and stateful systems, or cloud control planes, and apply it across our multi-account, multi-region AWS environment. You will lead work such as modernizing compute and stateful infrastructure, strengthening capacity and failure isolation, and building standardized infrastructure-as-code workflows and reusable automation. You will partner with product engineering teams to turn recurring risks and manual operations into durable platforms and paved paths. We do not expect you to be an expert in every infrastructure domain. We are looking for engineers who have built and operated critical systems at significant scale, understand how infrastructure fails, and can use that experience to improve both our platforms and our engineering practices.

In this role, you will: - 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. Minimum requirements for the role: - 6+ years of experience designing and building software, infrastructure, or distributed systems, including operating critical systems in production.
