Platform Engineer

Job Description

We are building a modern software delivery platform on serverless and edge infrastructure. Our stack runs on Cloudflare Workers and Vercel, and our platform engineering function exists to help every engineer ship quickly, safely, and with confidence.

We are looking for a Platform Engineer to own our internal developer platform end to end. This is a senior individual contributor role spanning CI/CD, edge infrastructure, observability, and developer tooling across a TypeScript and Python monorepo. You will treat internal engineers as your primary users and measure success by their productivity. The role has a clear growth path toward Staff or Principal-level engineering.

Key Responsibilities

• Design and maintain GitHub Actions workflows across a monorepo, including reusable workflows, OIDC federation to Cloudflare and Vercel, and a comprehensive CI quality bar covering type-checking, linting, testing, and SAST
• Own the full deployment pipeline from branch to preview to production, including artifact signing, SBOM generation, and supply chain security practices
• Instrument Python and TypeScript services with OpenTelemetry, own OTel Collector configuration, and establish a vendor-neutral observability strategy covering traces, logs, and metrics across edge compute environments
• Define SLOs with product teams, implement error budget alerting, and set the organization-wide logging contract
• Own Cloudflare and Vercel configuration as code via Terraform or Pulumi, ensuring all infrastructure changes are PR-reviewed and version-controlled
• Build and maintain internal CLIs and scaffolding tools that provision new services pre-wired with CI, OTel, and deployment configuration
• Maintain an AI-aware development environment with agent-safe sandboxing and governance guardrails for AI-generated code entering production
• Track and report on platform impact: deployment frequency, PR cycle time, time-to-production, and developer satisfaction

Requirements

• Demonstrated experience in platform engineering, DevOps, or developer experience engineering in a professional context
• Strong hands-on proficiency in Python, TypeScript, and Bash
• Deep experience with GitHub Actions, Infrastructure as Code (Terraform or Pulumi), and OIDC-based keyless authentication
• Working knowledge of OpenTelemetry and software supply chain security practices
• Familiarity with edge compute platforms, particularly Cloudflare Workers and Vercel
• Strong written communication; able to produce documentation and architecture decision records that let the platform operate without direct intervention
• Self-directed and comfortable shaping a function that is still early in its development

Preferred Qualifications

• Experience with Sigstore or cosign, policy-as-code tooling (OPA), or internal developer portals (Backstage)
• Background in FinOps or cloud cost attribution
• Experience designing CI/CD systems that accommodate AI coding agents and non-deterministic code generation workflows
