We are seeking a highly experienced Principal Platform Engineer to lead the technical direction of our core infrastructure, identity, and data platforms. In this role, you will be responsible for designing and evolving shared foundations that enable product teams to deliver high-quality software at scale. You will work at the intersection of distributed systems, cloud-native architecture, and developer experience, driving both strategic architectural decisions and hands-on execution.

Key Responsibilities

  • Data & Analytics Infrastructure: Design and implement modern data lakehouse architectures (AWS, Iceberg, Redshift) and governance models to support scalable data products.
  • Observability & Reliability: Oversee cloud-native monitoring and observability pipelines, leveraging Kubernetes, Prometheus, and Thanos to ensure enterprise-grade visibility.
  • Developer Experience (DevEx): Drive AI-assisted SDLC initiatives and establish integration patterns that accelerate product onboarding and migration across cloud environments.
  • Technical Mentorship: Act as a technical lead for multiple engineering teams, fostering a culture of excellence through coaching, architectural decision records (ADRs), and spec-driven development.

Required Skills & Qualifications

  • Proven experience as a Principal or Staff Engineer in a large-scale, distributed environment.
  • Expertise in AWS, Kubernetes, and Go, Java, or Node.js.
  • Deep understanding of IAM protocols (Auth0, OAuth, SSO/SAML, OpenFGA).
  • Experience building and scaling data platforms using Medallion architecture and cloud-native tools.
  • Strong background in DevOps/SRE practices, including CI/CD (GitHub Actions, ArgoCD) and Infrastructure as Code (Terraform).

  • Background in highly regulated environments (SOC2, FedRAMP).
  • Active contribution to open-source projects or industry conferences (e.g., Solr, CNCF).
