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: In this newly-created Staff Software Engineer role, you will architect the technical foundation for global fleet sustainability, digitising the massive transport and infrastructure sectors that power our world. Our focus isn't on traditional cost-saving; it's on resource efficiency at a global scale. At Samsara, Staff Engineers are hands-on technical leaders who bridge high-level architectural strategy with a relentless builder mindset. Operating with empowered autonomy, they tackle the most ambiguous challenges at the intersection of physical and digital operations. Unlike traditional architects, they stay deeply close to the implementation—maintaining an active "hands-on" presence in the codebase—to drive rapid innovation and maintain velocity. They act as force multipliers, raising the technical bar through thoughtful mentorship and pragmatic decision-making, ensuring that every line of code translates into tangible impact for the world’s foundational industries. In this role, you will lead the technical strategy for our Sustainability suite—from refining raw, inconsistent sensor signals into high-fidelity data for precise energy monitoring, to building the complex global infrastructure required for fleet electrification. By leveraging Samsara’s massive operational dataset, you will establish the technical foundation that empowers customers to reduce their carbon footprint, optimize real-time driver behavior, and significantly decrease fuel consumption across millions of miles. In this role, you will: - Architect and own the technical strategy for Samsara's entire Sustainability product suite, covering the full lifecycle of fuel and electric vehicle energy. - Lead the design and implementation of real time, complex, data-intensive systems, shipping production code that directly improves fuel efficiency for our customers. - Elevate the technical bar across the organization by mentoring and developing engineers, leading critical architectural decisions, and driving alignment around a cohesive long-term technical vision. - Spearhead initiatives that leverage vast datasets to solve ambiguous problems, such as driver efficiency and signal processing for raw sensor data. - Drive technical direction and build consensus across multiple product and engineering teams, acting as the key technical partner to leadership. - Operate with a high degree of autonomy to identify and solve our most challenging technical problems, taking full ownership from initial concept to operational reality. What we look for: - Proven impact designing, building, and operating real-time, distributed, fault-tolerant systems at scale, with a systems-oriented mindset and a deep understanding of long-term architectural trade-offs. - A history of hands-on contribution at a senior level. You are a builder who believes the best architects are close to the implementation. - You are a pragmatic decision-maker who excels in a fast-paced, high-stakes shipping cycle. You have the stamina for a relentless build pace and the ability to drive results quickly within a complex, global engineering team. - An ability to multiply the impact of those around you. You raise the standard through clear communication, thoughtful mentorship, and an ability to make complex ideas simple. - Experience working with large-scale data processing or machine learning pipelines. You are comfortable diving into raw data to find patterns and solve customer problems. - A deep sense of ownership and the ability to drive multi-quarter, cross-functional initiatives to completion without waiting for direction. Total Rewards At Samsara, we build for the people who keep the global economy moving. We want owners, not passengers, which is why our rewards are designed to fuel high-impact builders. Our compensation program delivers above-market total compensation through a combination of base salary, performance-based bonus/variable pay, and equity (for eligible roles) in a high-growth public company. We meaningfully differentiate pay for our top performers, who have the opportunity to earn above-market compensation that can outpace the broader market over time. Beyond compensation, we provide the foundations that enable long-term success: a flexible, employee-led remote model, a professional development stipend, comprehensive health and parental leave plans, and more. If you’re ready to build for the long term and own the outcome, your journey starts here.
