Note: The job is a remote job and is open to candidates in USA. Samsara is the pioneer of the Connected Operations Cloud, helping organizations that depend on physical operations use IoT data to improve safety, efficiency, and sustainability. The Senior Platform Engineer will own the platform foundation for Growth Product Engineering, including secure CI/CD, AWS infrastructure, observability, security engineering, self-service tooling, and AI-assisted SRE capabilities. The role also contributes to backend product development and mentors engineers.
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 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 tooling
- 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
Skills
- 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
- 6+ years of professional software, infrastructure, DevOps, platform, or site reliability engineering experience
- Hands-on AWS production experience (IAM, Lambda, networking, and multi-account organizations) with Infrastructure as Code such as Terraform, AWS CDK, or CloudFormation
- Designed and operated CI/CD pipelines (GitHub Actions, buildkite) with automated testing, static analysis, coverage enforcement, and deployment gates, plus safe release patterns such as blue/green, canary, feature flags, and reliable rollbacks. We use GitHub Actions workflows for CI/CD
- Strong Python development experience across services, tooling, and automation, working familiarity with JavaScript-based stacks, and experience with containerization and orchestration (Docker with ECS, EKS, or Kubernetes)
- Cloud security posture management (CSPM) or our tools like Wiz, semgrep, synk, etc
- Experience building observability into distributed systems: centralized logging, metrics, tracing, and alerting (for example Sentry, Datadog, CloudWatch, or Grafana)
- Track record of designing, building, and operating production infrastructure end to end with measurable gains in reliability, security, or developer velocity, using AI-powered development tools (for example Claude, Cursor, Codex, or Copilot) in a daily workflow
- Experience with product and feature development: building and shipping customer-facing product features, not just internal platform and infrastructure work
- Experience building the guardrails that make AI or agent-generated code safe to merge and deploy: mutation testing, coverage enforcement, ephemeral preview environments, or automated rollback
- A developer experience or platform engineering background, with a track record of paved-path tooling that other engineers actually adopt
- Familiarity with cloud cost management, performance regression detection, capacity planning, and disaster recovery plans rehearsed against measured RTO and RPO targets
- Exposure to localization pipelines and to GTM or data tooling such as Salesforce, Contentful, Hightouch, or Databricks, plus an experiment-driven approach to adopting emerging AI technologies
- Experience with Service Level Indicators (SLIs) and Service Level Objectives (SLOs) as the foundation for observability in our system
Benefits
- This role is also eligible for an initial RSU grant with no vesting cliff, and ongoing refresh opportunities tied to performance, subject to plan terms and conditions.
- Performance-based variable pay
- Equity (for eligible roles)
- A flexible, employee-led remote model
- A professional development stipend
- Comprehensive health and parental leave plans
- Remote work where it aligns with our operational requirements
