Sr Offensive AI Security 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 building a new role at the intersection of security engineering and applied AI. You'll be the most AI-forward technologist on our Application Security team. You'll use frontier AI models to find vulnerabilities across our cloud, software, and firmware before attackers do. You'll also evaluate each new model for security use and help build the guardrails for adopting AI safely.

This role reports into our App Sec team and has a clear path to shape Samsara's AI security strategy.

This role is open to candidates residing in the US except the San Francisco Bay Metro Area, NYC Metro Area, and Washington, D.C. Metro Area.

You should apply if:

• You want to impact the industries that run our world: Your efforts will result in real-world impact – helping to keep the lights on, get food into grocery stores, reduce emissions, and most importantly, ensure workers return home safely.
• You are the architect of your own career: If you put in the work, this role won’t be your last  set up our employees for success and have built a culture that encourages rapid career development, countless opportunities to experiment and master your craft in a hyper growth environment.
• You’re energized by our opportunity: The vision we have to digitize large sectors of the global economy requires your full focus and best efforts to bring forth creative, ambitious ideas for our customers.
• You want to be with the best: At Samsara, we win together, celebrate together and support each other. Youwill be surrounded by a high-calibre team that will encourage you to do your best.

In this role, you will:

• Deliver accurate, consistent security assessments of Samsara's software, code, and firmware, evaluating their resilience against AI-driven/adversarial attacks, and implementing fixes.
• Create and translate general AI security findings into Samsara-specific fixes for our application security layer— including adapting techniques built for software to apply to hardware and embedded firmware.
• Find both AI-specific and traditional vulnerabilities (e.g., injection, IDOR) using AI-driven offensive validation.
• Build and pressure-test novel AI-enabled security tooling and workflows, then drive adoption of what proves valuable across the broader security org.
• Benchmark each new frontier model against the previous one for security tasks, and build the release criteria and guardrails for adopting it.
• Support App Sec vulnerability triage through an office-hours rotation, and help run our bug bounty program, with potential expansion to hardware.
• Partner cross-functionally with engineering, hardware, and leadership. Present findings to security and executive leadership as Samsara's go-to expert on AI-related security risk.
