Software Engineer II

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:

Samsara is seeking an experienced Site Reliability Engineer to join our Infrastructure Platform Security team.

The Infrastructure Platform Security team is responsible for the security, compliance and evolution of Samsara’s public cloud infrastructure. Using industry best practice approaches, we pave the path toward secure-by-default configurations, reducing security and compliance friction for our partnering product teams.

In this role you will directly contribute towards the evolution of Samara’s public cloud infrastructure, ensuring that it remains secure, optimised and reliable.

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:

• Design and maintain highly available, resilient and secure infrastructure across Samsara’s public cloud.

• Own infrastructure provisioning using Infrastructure as Code (IaC) to establish reliable “paved paths” for seamless developer self-service.

• Develop and maintain standardized, secure, and reliable base components like “golden images” (AMIs/container images) for fault-tolerant provisioning.

• Drive system stability and service quality by embedding reliability best practices directly into development and deployment pipelines.

• Ensure service availability by participating in a 24/7 on-call rotation, investigating outages, and contributing to root cause analysis/post-mortems.

• Define SLIs/SLOs and build observability tooling to measure and improve service reliability.

• Develop and maintain monitoring dashboards, metrics pipelines, and alerting configurations.

• Own and lead the technical delivery of engineering projects, ensuring execution meets agreed-upon timelines.

• Design and scope solutions, evaluate options and make trade-off decisions to provide accurate effort and complexity recommendations.

• 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:

• 5+ years of experience as a DevOps Engineer, Security Engineer, Software Engineer or Site Reliability Engineer

• 5+ years hands-on experience of Unix or Linux

• 3+ years hands on experience of public cloud networking engineering

• 3+ years of experience of Identity & Access Management

• Strong ability to automate through scripting languages such as Python, Bash, Go, or similar

• Experience with Infrastructure as Code (e.g. Terraform, Ansible, Puppet)

• Experience in implementing and managing containerized applications using Docker and orchestration platforms like Kubernetes, with security considerations in mind.

• Experience with AWS services such as EC2, EKS, ECS, ECR, IAM

• Understanding of security weaknesses, exploits, attacks and mitigations

An ideal candidate also has:

• Experience with AWS and GCP public cloud infrastructure

• Experience securing cloud networks ( e.g. VPCs, ACLs, Security Groups, Network Firewalls, DNSSEC)

• Experience with Security as Code (SAST/ SCA security tools)

• Strong communication skills and desire to collaborate across teams

• Excellent problem-solving skills and ability to troubleshoot network and security-related issues.

• Experience with performance and cost optimization as applied to cloud infrastructure

• Familiarity with data privacy regulations and compliance…
