Senior Software Engineer II, Fleet Safety

About the role:

The Risk Intelligence team builds fullstack systems and customer-facing products that power Samsara’s AI-driven safety and risk solutions. Our mission is to transform massive streams of video, telemetry, and contextual data into actionable insights that help fleets reduce accidents, exonerate drivers, and manage operational risk. At scale, this means not only detecting risky driving behaviors but also uncovering complex patterns across vehicles, infrastructure, and environments to provide a holistic view of safety.

As a Senior Software Engineer II on the team, you will design and deliver AI-powered products across web, mobile, and API surfaces that surface new detections and insights at scale. You’ll collaborate closely with Product, Design, and ML teams to integrate cutting-edge models into customer workflows, own complex technical problems spanning data pipelines to front-end experiences, and deliver scalable, reliable systems that improve real-world outcomes for fleets globally.

This is a remote position open to candidates residing in the US.

You should apply if:

• You want to impact the industries that run our world: The software, firmware, and hardware you build will result in real-world impact—helping to keep the lights on, get food into grocery stores, and most importantly, ensure workers return home safely.
• You want to build for scale: With over 2.3 million IoT devices deployed to our global customers, you will work on a range of new and mature technologies driving scalable innovation for customers across industries driving the world's physical operations.
• You are a life-long learner: We have ambitious goals. Every Samsarian has a growth mindset as we work with a wide range of technologies, challenges, and customers that push us to learn on the go.
• You believe customers are more than a number: Samsara engineers enjoy a rare closeness to the end user and you will have the opportunity to participate in customer interviews, collaborate with customer success and product managers, and use metrics to ensure our work is translating into better customer outcomes.
• You are a team player: Working on our Samsara Engineering teams requires a mix of independent effort and collaboration. Motivated by our mission, we’re all racing toward our connected operations vision, and we intend to win—together.

In this role, you will:

• Build and release new features rapidly, validate with customers, and evolve them toward robust, scalable solutions.
• Solve complex problems and own the success of your solutions as you architect, build, test, and deliver fullstack products.
• Build upon skills and knowledge across a range of technologies, such as Go, GraphQL, TypeScript, React, and MySQL (prior experience with these is not required).
• Own the operational health of production systems as we scale to an ever-growing customer base.
• Make an impact on our core architecture, roadmap, and the wider engineering community.
• 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:

• 8+ years of experience in software development.
• Proven experience shipping features to customers and iterating based on feedback.
• Strong communication skills and a collaborative mindset; able to explain design choices and welcome feedback.
• A growth mindset and enthusiasm around building new skills and expertise.
• Comfortable building end-to-end solutions; preference for frontend or backend is fine, but you should be excited to work across the stack.
• Maintain production systems your team owns and provide operational support when necessary.
• Demonstrated strong interest in AI technologies and experience as an early adopter of AI tools.

An ideal candidate also has:

• 5+ years of fullstack experience in a fast-paced environment, ideally contributing to an early-stage product and scaling it for growth and impact.
• Mastery of data modeling and fullstack application architecture at scale.
• Experience deploying LLM-powered systems into production for customer-facing features.
• Experience collaborating effectively on geographically distributed teams.
• Background maintaining software products at scale.
• Familiarity with Go, GraphQL, TypeScript, React, and AWS (a plus, not required).
