Fullstack IoT Engineer
Reply Polska
This role is for building scalable IoT cloud platforms at OBI Smart Technologies (joint venture between OBI and Reply). You will primarily develop backend services using TypeScript/Node.js/NestJS, design REST APIs, and leverage AWS services like IoT Core, Lambda, SQS, Kinesis, and Timestream for device communication and telemetry ingestion. You'll also work with PostgreSQL/Aurora, TypeORM, and contribute to infrastructure as code with Terraform/OpenTofu, Docker, and CI/CD. Occasionally, you'll work on frontend components in Vue 3. The role is hybrid in Katowice (1-2 days in office per week).
Brakuje: team size and composition, on-call or after-hours support requirements.
This role is primarily a Backend Engineer for IoT cloud platforms, with occasional frontend contributions. The title 'Fullstack IoT Engineer' overemphasizes the fullstack aspect; the daily work is heavily backend with AWS services and TypeScript/Node.js.
