Platform Engineer– Department of Technology – (1043) at CityAndCountyOfSanFrancisco1

The Department of Technology is seeking a Senior IS Engineer to join the Platform Engineering team as a lead cloud migration and modernization engineer. This position provides senior technical leadership for Cloud 2030, the City’s five-year program to migrate approximately 1,700 workloads from on-premises data centers to commercial cloud platforms. The position requires hands-on engineering: writing Terraform daily, building CI/CD pipelines, executing database migrations, modernizing legacy codebases, developing custom applications, and leading complex multi-cloud deployments from architecture through production cutover. The ideal candidate writes infrastructure-as-code fluently, has led cloud migrations of meaningful complexity, and is comfortable working across multiple cloud providers. The Platform Engineering team is undergoing a transformation from traditional systems administration to a modern engineering organization. We use GitHub for version control and CI/CD, Terraform for infrastructure-as-code, and AI coding tools (Claude Code, AWS Kiro) as part of our development workflow. We are accelerating adoption of containerization and cloud-native patterns across the team. You will help develop and further this technical and cultural change. We build and operate cloud environments that host criminal justice systems, financial systems, and public-facing applications for a city of 880,000 residents. Essential duties include, but are not limited to, the following:  • Design and implement multi-cloud infrastructure using Terraform/OpenTofu • Build and maintain GitHub Actions CI/CD pipelines for infrastructure and application deployments • Lead end-to-end cloud migrations including network architecture, compute provisioning, database migration, and production cutover • Modernize legacy applications for cloud deployment (containerization, framework upgrades, CI/CD enablement) • Develop custom applications, automation tools, and internal platform services • Perform database migrations across Oracle, SQL Server, and PostgreSQL, including data transfer, performance validation, and high-availability configuration • Implement compliance controls (CJIS, HIPAA) as infrastructure-as-code • Conduct code reviews and establish engineering standards for the team • Mentor junior engineers on cloud architecture and modern development practices
