Staff Application Security Engineer

At Samsara, we embrace a flexible working model that caters to the diverse needs of our teams.

• Samsara sits at the center of hardware, software, AI, and the physical world, processing 25+ trillion data points annually across thousands of connected devices. The Samsara Application Security team protects this vast footprint end-to-end, spanning cloud services, internal systems, and firmware running on IoT hardware in the field.
• As a Staff Application Security Engineer, you’ll drive the overarching technical direction for our application security and vulnerability management programs. This is a high-visibility role where you'll influence a broad surface area while retaining the flexibility to dive deep into critical domain focus areas as security priorities evolve.
• Lead the ongoing strategy, operation, and continuous improvement of Samsara's vulnerability management program, along with other core application security programs — not just execute against an existing process, but define what the process should be.
• Own and drive down mean time to remediate (MTTR) across the vulnerability backlog, as SLAs tighten.
• Build and champion automation and tooling that scale vulnerability detection and response across cloud, firmware/IoT, and corporate systems, rather than relying on manual, one-by-one review.
• Set technical and architectural direction for the program, translating leadership's strategic priorities into a concrete execution plan for the team.
• Drive remediation by building trust with engineering teams and providing clear, actionable guidance — partnering with technical program management on reporting rather than owning it directly.
• Mentor and level up other engineers on secure design and remediation practices, and be a technical voice other teams look to when priorities are unclear.
• Communicate risk and remediation tradeoffs to engineering leadership in terms they can act on, without owning the relationship end to end.
• Participate in security incident investigations involving high-profile vulnerabilities, assessing potential impact on Samsara's infrastructure.
• Be regularly on call to support critical vulnerability response.
• 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

• 10+ years of relevant experience as a cloud engineer or security engineer, including hands‑on vulnerability management across a broad, multi‑product enterprise environment — not a single product or team's slice of it.
• Demonstrated ability to independently set technical and architectural direction for a security program, and to drive remediation across a broad, multi‑surface environment without direct authority over the teams doing the fixing.
• Significant experience with modern vulnerability management tooling (e.g., Wiz, Semgrep) and deep familiarity with vulnerability scoring frameworks such as CVSS and EPSS.
• Deep understanding of Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA).
• Hands‑on use of AI/LLM tooling in your own security workflow — triage, detection logic, remediation drafting — plus credibility speaking to how AI is changing the threat landscape and the tooling available to address it.
• Experience with C/C++, relevant to firmware and embedded systems.
• Background at a cloud‑native, AI‑forward company actively building agentic or AI‑driven products.
• Experience with security automation platforms (e.g., Tines) and serverless frameworks (e.g., AWS Lambda).
• Experience integrating vulnerability management into modern CI/CD pipelines with a "shift‑left"…
