Sr. Software Engineer II

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:

At Samsara, we’re building the connected operations cloud to transform the world’s physical operations. Our Identity and Access Management (IAM) team secures access for millions of users and protects the integrity of over 2.3 million connected devices worldwide. IAM is the foundation of our security posture, enabling customers to trust Samsara with their most critical data—while ensuring a seamless user experience at scale.

We are looking for a Senior Software Engineer to drive innovation and resilience across Samsara’s IAM platform. In this role, you will combine technical depth, security expertise, and leadership to shape our authentication and authorization strategy. You’ll work across the stack—from frontend and backend services to data storage and integrations—while mentoring teammates and influencing technical direction for one of the most business-critical areas of Samsara’s platform.

This is a remote position open to candidates residing in the US or Canada. Relocation assistance will not be provided for this role.

You should apply if:

• You want to impact the industries that run our world: The software 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 energized by the intersection of AI and security: Samsara’s IAM team is building the future of security for humans, services, and AI agents at scale. You think deeply about zero-trust architectures, agent AuthN and AuthZ, and enterprise identity security.


• 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:  

• Design and evolve IAM foundations for AI Agents, including agent identity, permission guardrails, and enterprise-grade audit systems.


• Design and build authentication and authorization systems that are reliable, standards-based, and performant for millions of global users.


• Propose and implement technical solutions, guide system architecture, and ensure features are integrated across the stack (frontend, backend, databases, APIs, AI agents).


• Partner with Infrastructure, Security, Compliance, and Product Engineering to solve complex, cross-functional risk and governance challenges.


• Support and develop engineers on the team through code reviews, design discussions, and career development.


• Contribute to our culture and maintain an inclusive, collaborative and supportive work environment where all Samsara employees can grow and thrive.


• 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 building and operating production software using modern engineering practices.


• Strong understanding of cloud security, IAM systems, threat models, and mitigations.


• Strong programming/coding fundamentals in a language such as Java, Python, or Golang


• Experience designing and operating highly reliable, scalable distributed systems.


• Experience building security-sensitive or identity-related systems in production.


• Bachelor’s Degree in Computer Science/Engineering or equivalent experience.


• Strong communication skills and ability to influence without direct authority.

An ideal candidate also has:

• Enterprise Identity and Access Management experience: OAuth2, OIDC, SSO, SAML, JWT, Session Management, or adjacent identity/security systems.


• In-depth experience with AWS, Azure or GCP.


• Experience building secure authentication or authorization capabilities for web and/or mobile.


• Experience building AI Agent or Non-Human identity platforms.
