Platform Engineer (Middle / Senior) AWS & Terraform, Developer Platform
DataArt
Project overview
The project is focused on evolving and enhancing an internal developer platform that supports hundreds of services running on AWS. The platform enables engineering teams to build, deploy, and operate applications efficiently through shared tools, automation, and cloud infrastructure capabilities. You will contribute to platform services, developer tooling, and infrastructure automation while implementing cloud infrastructure changes using Terraform and Infrastructure as Code practices. The project emphasizes scalability, reliability, security, and an improved developer experience across the engineering organization.
Team
You will work within a collaborative platform engineering team consisting of software engineers, platform engineers, and technical leads. The team partners closely with delivery teams across the organization, sharing platform standards, infrastructure patterns, and best practices while supporting Agile delivery processes.
Position overview
This role is well suited to engineers who have built and maintained internal platforms, developer tooling, or shared services - rather than working exclusively in traditional infrastructure-focused DevOps or Site Reliability Engineering environments. You will work across application development, platform engineering, and cloud infrastructure to improve developer experience, increase automation, and support reliable service delivery at scale.
