Who We Are

Samsara (NYSE: IOT) is the pioneer of the Connected Operations™ Cloud, 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 help improve the safety, efficiency, and sustainability of the physical operations that power our global economy. Representing more than 40% of global GDP, these industries form 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 part of 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.

As a member of our Security Operations Team, you will collaborate with a global team of engineers to monitor and respond to security events, lead security incidents as Incident Commander, and lead digital forensic investigations in support of Employee Relations, Legal, Compliance, or Information Security cases. Although you will be focused on security incident response, you will also have the opportunity to create and maintain runbooks, automated workflows, and assist in process refinement and implementation. You will collaborate with a diverse team of engineers and key stakeholders on security initiatives across the company. Above all, your focus is bringing Security expertise to the table in a collaborative, humble, and practical manner.

Location: This role is open to candidates residing in the UK

You should apply if

• You want to impact the industries that run our world: Every phone call you answer and every email you send can affect whether truck drivers deliver goods on time and without accidents, whether students get dropped off safely from school, or whether power gets restored quickly after a natural disaster.
• You thrive the most when solving problems: Our constantly expanding technology and the complexities faced by our customers provide an exciting range of challenges for our Customer Success teams. With a growth mindset and a desire to learn, you will strategically partner with our customers to find unique solutions to help keep their operations safe, efficient, and sustainable.
• You are a natural relationship builder: Whether the relationship is with our customers or with cross‑functional teams in Samsara, you are in constant communication and collaboration with key stakeholders to win as a team.

In this role, you will

• Monitor security events and provide technical analysis on alerts.
• Lead information security incidents and employee insider investigations by developing the incident response strategy, leading the execution through incident closure, while providing incident updates to key stakeholders throughout the incident.
• Deliver security guidance clearly and concisely for incident response and insider threat initiatives.
• Coordinate the building of services, capabilities, integrations, and implementations of technologies to support security operations, incident response, and insider threat.
• 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.
• Participate in our on‑call rota covering weekends.

• Understanding of analysis and forensics techniques on macOS, Windows, and Linux.
