Senior Platform Engineer for AI-Driven CI/CD & Cloud Infra

Samsara; United States; Remote; USD 140,000 - 190,000; Full time

Job summary

The company is seeking a Senior Platform Engineer to join Growth Product & Engineering and own the platform that supports our growth teams. You will design and harden the CI/CD pipeline, migrate AWS resources to IaC, and enable self-service infrastructure across accounts.

You will lead security engineering, centralized logging, and scalable release strategies, while mentoring engineers and advancing a culture focused on customer success and long-term growth.

Qualifications

• 6+ years of professional software, infrastructure, DevOps, platform, or SRE experience.
• Hands-on AWS production experience with IaC such as Terraform, AWS CDK, or CloudFormation.
• Designed and operated CI/CD pipelines (GitHub Actions, Buildkite) with testing and deployment gates.
• Strong Python development and familiarity with JavaScript stacks; containerization 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.
• Give engineers a fast, safe inner loop with ephe­meral per‑PR environments and local tooling, including isolated databases seeded from realistic data.
• 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 the company’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 tooling.
• Champion, role model, and embed the company’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
