Job summary

Samsara is seeking a Senior Platform Engineer to own the foundational platform for Growth Product & Engineering, enabling AI-assisted development. You will tackle security, observability, and scalable infrastructure across AWS in a fast-growing environment.

The role emphasizes building safe pipelines, governance, and self-service tooling while mentoring engineers and aligning with Samsara’s cultural principles.

Qualifications

• 6+ years of professional software, infrastructure, DevOps, platform, or site reliability engineering experience.

Responsibilities

• Own the CI/CD foundation for AI-assisted and agentic development: hardened pipeline gates, high test coverage, mutation and end-to-end tests, blocking security scans, performance and cost regression guards, and progressive delivery with automated rollback.
• Provide engineers a fast, safe inner loop with ephemer…
• Build centralized logging, monitoring, and alerting across our AWS footprint so every team has visibility and bad deployments roll back automatically.
• Lead security engineering: remediate vulnerabilities, establish secure-by-default patterns, and automate code scanning, secrets management, and access control.
• Migrate hand-built AWS resources to Infrastructure as Code, separate production and pre-production accounts, and stand up tested backup and disaster recovery with clear RTO and RPO targets.
• Build paved-path, self-service tooling and standardized blue/green, canary, and feature-flag releases, while mentoring engineers and role modeling Samsara’s cultural principles as we scale.
• Build and operate AI agents for SRE work: automated alert triage, incident investigation, and safe self-healing remediation, so on-call toil drops as our service footprint grows.
• Contribute to backend development for products: assist with backend cloud services product work, shipping customer-facing features alongside the platform, not just internal platform and infrastructure work.
• 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
