Infrastructure Engineer, Data Platform

About the Role

Together AI is hiring a Lead Cloud Infrastructure Engineer to own and operate the cloud foundation that powers our rapidly scaling data platforms. In this role, you will be the primary engineer responsible for defining, building, and maintaining the AWS infrastructure that underpins data engineering systems across the company — from internal analytics pipelines to customer-facing metering and billing systems.

You will work closely with multiple data engineering teams, enabling them to move faster by building reliable, secure-by-default infrastructure they can depend on. You’ll partner with our dedicated security engineering team to ensure best practices around IAM, network design, and data lake access — while focusing on platform reliability, scalability, and developer experience.

This is a high-ownership, hands-on engineering role. You’ll manage everything from Terraform modules and CI / CD pipelines to Lake Formation permissions and observability tools — with a mandate to build infrastructure that just works, and keeps working.

Responsibilities

• Own the design, implementation, and operation of all AWS-based infrastructure supporting data systems
• Build and maintain reproducible, well-documented Terraform infrastructure modules
• Collaborate with multiple data engineering teams to understand and support their infrastructure needs
• Implement and maintain IAM policies and Lake Formation permissions in partnership with the security engineering team
• Build internal tooling and automation to support self-service infra provisioning
• Monitor infrastructure health and cost, and drive continuous improvements in reliability and efficiency
• Serve as the point person for infrastructure questions, issues, and requests across the company’s data platforms
